the map that divides Spain in two through its two large hydrographic basins

by

This curious map that divides the Spanish state into blue and red could represent political or administrative borders, but the partition is much more curious and striking: it shows the final destination of each drop of rain that falls in Spain. Each line you see is one of the many rivers that run through this part of the Iberian Peninsula and its color reveals where it will end: in the Mediterranean Sea or in the Atlantic Ocean. The result is one of the most beautiful and revealing hydrological portraits of the Iberian Peninsula. Based on data from the Ministry for the Ecological Transition and Demographic Challenge, the cartographer and GIS consultant Joe Davies has put together This map of watersheds that reveals the invisible spine that runs through the state, the continental watershed. The result is surprising to say the least. In addition to the colors, the route is more or less marked depending on the flow of the river, thus revealing which rivers are the largest. That invisible line slides approximately through the Iberian System and the Pyrenean foothills, dividing the territory into two water worlds. There are several things that draw attention to the image: the first thing is the proportion. The Atlantic takes up about two thirds of the territory. But also that although Spain “looks” towards the Mediterranean, its rivers flow mostly to the west. There is a geological reason that explains it: the Central Plateau It tilts slightly towards the Atlantic, a legacy of the Hercynian tectonics that shaped the Iberian base 300 million years ago. The curious layout of the continental watershed in Spain He Ebro river is the great traitor: Born in Cantabria, just 20 kilometers from the Cantabrian Sea. By geographical logic one would expect it to be Atlantic, but no: its entire large basin is painted the color of the Mediterranean, where it empties after traveling almost a thousand kilometers. The Pyrenees functioned as a barrier and the Iberian and Catalan Systems as a funnel, so the river was forced to flow westwards. A striking example of how the orography is capable of hijacking a river and taking it to another sea different from the one where it would belong. Another river that constitutes a curious case is the Segura: it originates in the Sierra de Segura in Jaen, more than 300 kilometers from the sea. Afterwards, it travels an enormous distance to empty into Alicante with a low flow, something that can be seen in comparison with neighboring Gualquivir. The explanation lies in the extreme aridity of its basin and the intense agricultural pressure. Where does each drop of rain that falls in Spain go. Joe Davies with data from the Ministry for the Ecological Transition and Demographic Challenge As one might expect, Galicia is very red on Davies’ map: it is a truly dense tangle that contrasts with the rest, especially if we move away from the Cantabrian coast. Galicia receive between 1,500 and 2,000 mm of annual precipitation, on a substrate of practically impermeable granites and slates, so the water does not filter, it drains. The result is that density of rivers and streams, all Atlantic, short and mighty. It is the region that best illustrates the direct relationship between geology, climate and river network. If the map were of all of Europe, Galicia would still stand out. The map also gives us unthinkable colorslike Pamplona being colored in Blue despite being a northern city extremely close to the Cantabrian Sea: its waters go to the Mediterranean through the Ebro and its tributaries. Madrid is red: the Manzanares-Jarama-Tajo takes it to the Atlantic. It has the continental divide very close, less than 80 kilometers away. On either side of that barrier, the water that falls in the same downpour ends up in seas separated by thousands of kilometers. 3D version with inverted colors.

The map of Spain where you can see how healthy the tap water in your town is

by

Water management in the Spanish state has several fronts: from the purely hydrological to the increasingly frequent shortage scenarios to the quality of this. Yes, the water that reaches the tap has passed through a water treatment plant and is therefore suitable for consumption, but there is a pollutant to keep an eye on: nitrates. The filtration of nutrients from the industrial agricultural activity so widespread in Spain brings about the degradation of ecosystems and also jeopardizes the security of public supply by saturating the self-cleaning capacity of aquifers and exceeding, in many cases, the treatment capacity of local water treatment plants. Although checking the quality of the water that reaches your tap is a resource accessible to citizens through platforms such as the National Consumer Water Information System (SINAC), the reality is that sometimes databases are too technical and dense, so someone has thought of converting the information from the Ministry of Health into an interactive map that is understandable to everyone. Is “the water of your town“and is a public consultation tool so that anyone who wants to know the quality of tap water of your municipality regarding nitrates, you can do so without needing technical knowledge through an interactive map that is easy to interpret. The map in question has been developed by DATADISTA based on official data from SINAC, which depends on the Ministry of Health and collects the analytical results of all drinking water supply networks in Spain. It is important to highlight that the last reading dates from April 2026 and does not contain real-time measurements, but rather the frequency varies depending on the supply area. Thus, while those networks that distribute more than 10 cubic meters per day have to report, those that are smaller the report is voluntary. Hence, some small rural towns appear without data. To make it easier, it comes with a direct search engine. Datadista The map shows the Spanish state with an OpenStreetMap map and points distributed throughout the territory on a color scale that goes from red for those who do not comply with the regulations to green for those who comply, passing through intermediate tones for risk or surveillance situations. In addition to being able to zoom and move the map or the Canary Islands having its own button to center the image on its archipelago, in the upper area are the layers that we can activate to view information such as the Nitrate Vulnerable Zones declared by the autonomous communities or the chemical state of the underground aquifers. In the lower left corner, the legend that explains the limits. If you prefer not to search on the map, at the top of the website there is a search box that speeds up everything and a brief summary of those critical areas. How good (or not) is the water in your town? Municipalities that fail to comply, critical points and control points. Datadista At first glance, a clear correlation is obtained: the most affected areas are concentrated in areas of intensive irrigated agriculture, especially in the interior of the peninsula. If you also activate the aquifer layer, transparent white and in the bottle: there is one direct relationship between agricultural intensity and water pollution underground with which the population is supplied. The categories in which the municipalities are classified are four: It fails to comply when any network registers 50 mg/L or more of nitrates, which is the parametric value set by European regulations and the Royal Decree 3/2023. Critical point: nitrates consistently exceed 30 mg/L. It is 60% of the legal limit and obliges the operator to develop a Water Health Plan with corrective measures. Control point, for those municipalities where high episodes have been detected but on a punctual and non-sustained basis. Complies, for municipalities that do not present a relevant risk due to nitrates. Be careful because there are 201 municipalities and almost 91,000 people supplied within that “non-compliant” range and 885 municipalities and more than a million people who drink tap water in critical areas. It is important to consider that the final state of a municipality is always determined by the worst state of all its supply networks. The nitrate problem. Nitrates reach the water due to the excess of nitrogen fertilizers and livestock manure, which, applied to the field (whether directly or not), are oxidized by bacterial action, transforming into nitrate, a very soluble anion that the soil does not retain and that easily infiltrates into the aquifers and rivers from which the population is supplied. The 50 mg/L limit was set by the WHO between the decades of the 50s and 60s to prevent acquired methemoglobinemia (blue baby syndrome) in infants due to high levels of nitrates in well water, the use of uncontrolled groundwater for infant formulas is not recommended. But science has shown that the problem is more serious than that legal limit. Without going any further, a Danish study from 2018 showed that there is a greater risk of colorectal cancer from just 3.87 mg/L, the MCC-Spain project found links to aggressive prostate tumors even below that current limit. In fact, in 2025 an international group of science professionals recommended lower this safety threshold to 6 mg/L, a figure that is very far from what comes out of the taps of numerous municipalities in the state.

The entire global electricity grid, in an impressive interactive map that shows the evolution of the energy transition

by

There are few infrastructures as complex and essential to living in the world as we know it as the electrical grid, which in practice for most mortals is reduced to touching a switch or connecting a plug to the socket and it works. Behind the world’s electrical infrastructure there is a huge conglomerate of equipment, careful planning and uses that are changing (among other things, due to the now so famous data centers). It is not the only thing that is being transformed: the energy transition is making it possible for those resources that once supplied the electrical grid to give way to renewable energies. But not all countries in the world have the same density of electrical networks or the same sources, because in fact there are real black holes in this very complete world map of the electrical network. Is called OpenGridWorks and is an interactive map of the entire world’s electrical infrastructure, from a small solar plant to the great lines that cross continents. And we already told you that it attracts attention not only for the beauty of the chromatic compositions, but also for practical purposes: from planning an engineering project to analyzing energy policy. Opengridworks This map is actually a web platform for geospatial visualization of electrical infrastructure. All its data comes from OpenStreetMap, the world’s largest open, collaborative geographic database, maintained by volunteers and experts on an ongoing basis. This guarantees global coverage, constant updating and completely free access. But for network and infrastructure data it uses information from Global Energy Monitor or the United States Energy Information Administration, among others. Its purpose is to show, in a clear and interactive way, where electricity is generated, how it travels through the grid and where consumption is concentrated. It is worth stopping at the layers and all the information it shows because as we warned you before it is very complete, so if you leave all the options activated you will find yourself in a mess. If you move on the map and get closer, you will be able to see information such as: What technology provides the energy in the form of a colored bubble: blue for hydroelectric, red for thermal, yellow for solar, green for wind and purple for nuclear. The size of each bubble represents the installed capacity in MW Transmission lines are drawn thicker the higher their voltage (from 100 kV to 765 kV) and substations appear as nodes where these lines converge. Data centers also appear in the shape of a white diamond as they are points of intensive consumption. On the other hand, easement strips (ROW) appear as shaded areas around lines and facilities. Opengridworks But you will also be able to see additional information when you hover the pointer over any of the points. An example: when touching the Montes de Cierzo wind farm in Tudela, we will see that it is in operation and the energy it provides. What the global electrical map reveals about the energy transition Playing with the zoom and scrolling you quickly discover that there are areas of saturation and others that are a desert of infrastructure. From an engineering point of view, the map allows you to search for the closest interconnection point for a new project or detect nodes whose failure would leave regions without supply. Beyond engineering, it is an energy policy tool: it highlights the electrification gaps in developing countries, shows the real progress of renewables compared to fossil fuels, and allows the resilience of different national networks to be compared. AND abysmal differences are observed. Opengridworks The densest networks They are concentrated in the United States, central Europe and China, while sub-Saharan Africa and central Asia show very poor coverage that reveals an electrical blackout. In South America, the areas with the most infrastructure are on the Atlantic coast, although there are also some timid points on the Pacific coast. However, inside we barely find more than a fade to black. The colors of energy sources also change on the map, still dominated by thermal generation, although in Western Europe and China the advance of solar and wind power is a reality already perfectly visible. This map also reveals curiosities such as that nuclear plants always appear next to rivers or coasts due to cooling needs and hydroelectric plants are concentrated in the large river systems of the world. The data centers are also not placed at random, but are clustered near large transmission nodes to ensure supply.

Most complete geological map reveals billions of years of impacts and volcanism

by

We have been talking for years not about landing, but about colonize Mars (above all, Elon Musk), but with Artemis II making history and the Orion ship just splashed down After the first manned mission to the Moon in more than 50 years, the old moon has returned to the forefront. Four astronauts have just photograph it up close and leave us with our mouths open. But the Moon is much more than a satellite full of craters: each of those craters tells a story of billions of years. At this moment when our satellite has hit us again, we rescue geological cartography most complete overview ever published. It is the unified geological map of the moonprepared in 2020 by the United States Geological Survey combining data from the lunar reconnaissance orbiter missions (LRO) from NASA and Kaguya from the Japanese Space Agency. The good thing is that although you can see a general sample, you can also download it to have a greater level of detail, since it is at a scale of 1:5,000,000 and derived from six digitized geological maps. Visually, this world map draws attention both for the number of craters and for the shades chosen to color it. The choice of color is not casual or ornamental, but rather each color represents a type of terrain with a specific age and origin. So, at a glance you know whether you’re looking at an ancient lava plain, a recent crater, or the original crust from 4 billion years ago. Without the colors, everything would be a gray mass of craters impossible to distinguish. The moon is full of secrets and this map provides information in abundance to discover them. The unified geographic map of the moon Fragment of the unified geological map of the Moon, scale 1:5M. Via: USGS The moon has five geological eras: Pre-Nectarian, Nectaric, Imbrian, Eratosthenic and Copernican, which range from 4,000 million years ago to today. How to differentiate them on the map? Because they go from purple and orange for the oldest to green and pink for the youngest. All that is seen is the fossilized record of its turbulent youth because it has been “geologically dead” for almost 3,000 million years, but it had a turbulent past as evidenced by its orography. The moon offers a striking visual dichotomy between the highlands (in reddish tones and saturated with craters) and the seas, which are the large dark spots. Of course, they don’t have any water. They are actually basaltic lava plains that filled huge impact basins about 3,000-4,000 million years ago. It is, in short, what we see from Earth. The clear, cratered areas constitute the original crust and are much older. The most characteristic thing about the Moon to the naked eye are the craters, which are something like scars that witness the passage of time: the more softened, diffuse and even buried it appears on the map, the older it is. On the contrary, the sharper, brighter and surrounded by bright rays, the younger. “Lightning bolts” are bursts of dust and rock launched after impact and can extend for many kilometers. There is two especially spectacular craters on the map: Tycho and Copernicuswhose rays cross hundreds of kilometers and are geologically very recent. The part of the Moon that we never see from Earth and that arouses so much curiosity in us (there is a project to install a radio telescope there) is its hidden side: there are almost no blue spots there. And while the visible side is rich in lava plains, the hidden side is a highland fortress, much more rugged and with a significantly thicker crust. Map At its south pole is the basin South Pole-Aitkenthe largest known impact scar in the entire Solar System, with 2,500 km in diameter and 8 km deep. Precisely that area where there are shadow craters science hopes to find water frost. This geological imbalance between both sides suggests that the Moon is asymmetric inside, a mystery that is also on the table of the scientific community.

A Spanish startup is building the map of the Earth that AI needs: Xoople

by

Xoople has closed a Series B round of 130 million dollars led by Nazca Capital and with the participation of MCH Private Equity, CDTI, Buenavista Equity Partners and Endeavor Catalyst. With the financing accumulated so far, 225 million dollars, the Madrid startup presents its candidacy for unicorn and becomes one of the most peculiar bets in the European space ecosystem. Why is it important. More than a round, this capital injection is the validation of a model that almost no one in the startup ecosystem has the stomach to execute: seven years building technology without going to market, without growth metrics to show to investors and with hardly any noise. Xoople has opted to be infrastructure before product, and that places it in a different category than almost any European space startup. The context. The company, founded in 2019 and based in Tres Cantos (Madrid), has developed its own constellation of satellites combined with an AI data processing platform called EarthAI. The goal is to become what its founders call the “Earth system of record” for the era of agentic AI: scientifically accurate geospatial data, ready to train models and feed autonomous workflows in enterprises. The comparison with Google Earth is superficial because what Xoople builds is data infrastructure, not visualization. In detail. He agreement signed with L3Harris Technologiesone of the largest aerospace defense contractors in the United States, is the piece that elevates the proposal. Its sensors, designed with defensive-grade technology and adapted for commercial use, promise to capture a volume of data two orders of magnitude greater than current monitoring systems. Marketing has started this year with clients in preview private between government agencies and companies of the Fortune 500. Between the lines. The investment pattern of this round says as much as the number. The CDTI has been in the capital of Xoople for some time and has it classified as a Strategic Company, the largest investment of your Innvierte program. That Nazca Capital, the most active fund in the Ibero-American ecosystem, leads the Series B together with MCH Private Equity is a sign that private capital already sees in Xoople something more than a technological promise. The milestone must also be read in terms of ecosystem: just a month ago, PLD Space closed 180 million euros of Series C. The Spanish space sector is no longer anecdotal. The big question. Xoople’s model requires its customers to rely on critical data infrastructure built by a startup. In sectors such as defense, climate management or urban infrastructure, this institutional trust threshold is a bottleneck, even more so than technology. The waiting list in preview private that the problem is being resolved. But climbing from a waiting list to long-term contracts with governments and global corporations is the leap he has yet to prove.

This map shows what the Earth will be like in 250 million years. If it comes true, Spain will be very lucky

by

About 200 million years ago, the last supercontinent began to break up. The division of Pangea It gave way, very little by little, to the current geological composition. But what was separated will come together again. The continents keep movingcrashing into each other, and one theory suggests that it will be within 250 million years when another supercontinent will emerge. We have named it as Pangea Ultimaand the truth is that it will not matter exactly which countries we have as neighbors. Pangea Ultima. plate tectonics It is curious because they continue to move one under the other, and that is what has led to the theory of continental drift. These movements are studied to understand the past, as well as to decipher the future, and one of those scholars is Christopher Scotese. This American geographer is the creator of the PALEOMAP Projectwhich seeks to show not only how the elements have moved these last 1,000 million years, but is also attributed the prediction of that future supercontinent. and Scotese elaborated this map: What is it that has inspired the one who opens this article: Curious neighbors. According to this, within about 50 million years North America would have rotated so much that Alaska would be at a subtropical latitude and Eurasia would also rotate, but in the opposite direction, making Britain closer to the North Pole. Africa will move closer to Europe and Arabia, both the Red Sea and the Mediterranean will disappear and, within 100 million years, the Atlantic will begin to shrink. It will be in 150 million years when the Atlantic will disappear as a result of being sucked in by the American continent, bringing America and that block composed of Eurasia and Africa much closer. And the culmination will occur within 200 million years when this new supercontinent is formed, with the Indian Ocean as a central sea and a curious neighborhood mix. According to this model, Latin America would be more or less the same, but with African neighbors to the east. Cuba would be attached to the United States, Greenland would be next to Canada (bad luck, Trump) and Spain would continue to border France and Portugal, but also with Italy, Morocco, Tunisia and Algeria. England would also be close to France and Korea would be in a curious sandwich between Japan and China. It will make exactly the same. But the truth is that it doesn’t matter what your new neighbors seem to you, not because, obviously, you won’t be there to suffer them, but because humanity may have become extinct by then. Not because we sometimes put effort into it, but because the conditions will not be the most ideal for the life of mammals. In a study Published in Nature, researchers predicted that 92% of the Earth would be uninhabitable for mammals. The reason is that, in a simulation of the climate of this new supercontinent, it is estimated that the temperatures of a large part of Pangea Ultima will be more than 40ºC, but in addition the amounts of CO₂ will make the life of mammals… complicated. Due to the number of collisions between plates, there will be great volcanic activity that will increase the CO₂ emissions into the atmospherea, not only warming the planet, but also encouraging the levels of this CO₂ to double the current levels. In addition, the Sun will be 2.5% brighter at that time because its nuclear fusion rate will have increased and this is something that will also contribute to making the planet drier. Spain not so bad. It’s not a very encouraging outlook, to be honest, since plant life will also experience mass extinction, but researchers point out that conditions may not be so bad in all parts of the new world. Thus, those closest to the top of the North Pole could have cooler conditions that facilitate better adaptation to life. And Spain, Portugal, Morocco or England are in that scenario. It is also possible that we become specialists in desert environments, becoming nocturnal animals in something similar to what was seen in ‘Dune‘. Alexander Farnsworth, one of the researchers who have simulated the climate conditions of that future, also analyzed From the most serious point of view, how life makes its way in the climate of Arrakis and points to this parallelism with the Earth in 250 million years. one more. Is this what the Earth will look like in 250 million years? Namely, but there are several hypotheses formulated in recent decades that, in one way or another, point to the existence of that supercontinent. One is Novopangeawhere the Pacific will close. another is Auricawith the closure of both the Atlantic and the Pacific. And another model is Amasiawith the union between Asia and America. And it doesn’t matter the model, they are still similar to the last Pangea and, after this new supercontinent, the estimate is that the Atlantic will open again, separating the countries and beginning a new cycle of rupture. What will happen to life? Well, it will make its way, as the great Jeff Goldblum already said in ‘jurassic park‘, because mass extinctions… there have been several.

This cool 3D map of light pollution turns cities into mountains of light

by

This 2026 is the year that opens a fantastic period to enjoy astronomical milestones, since the first of the three eclipses planned between 2026 and 2028: it will be next August 12, it will be a historic event in these latitudes (it has been more than a century since the Iberian Peninsula has witnessed a total solar eclipse) and not everyone will be able to see it: It will only be total in a strip. Being in the right place at the right time is only the first step: the next thing to be able to enjoy both the solar eclipse and any astronomical event, or simply to be able to see the stars well and distinguish constellations is total darkness. Or at least, try to be in a place free of light pollution. Getting away from the big cities is the first step as they tend to be the main sources of light, but not the only one: there are many infrastructures that can spoil the experience. Our recommendation if you plan to see the solar eclipse is that you do not leave it to improvisation and be clear about where to go to enjoy it better and here in addition to the map of the National Geological Institute To follow it, it is worth having on hand a good light pollution map. Where the solar eclipse will be seen: areas where it will be total and areas where it will be partial. IGN But does a light bulb next to you bother you so much to see the sky?? Yes, essentially because it is never usually just a light bulb. In fact, it’s not even just too much light. An example: when you approach a city with your car and it is getting dark or it is night, you can see a glow of the sky (skyglow) fruit of the rebound of light against dust particles, humidity and aerosols in the atmosphere, returning as a luminous veil that destroys astronomical observation. The underlying problem is the increase in the brightness of the sky: a star or a nebula does not compete against darkness, but against that background. If the background is brighter, the contrast drops (excepting the distances, it is like cheap TVs with bad backlighting scheme). The heavens are measured by the Bortle scalewhich goes from 1 to 9 where a class 1 sky is the darkest possible, practically a miracle in continental Europe (most medium-sized cities are around 7 – 9). With a class 9 sky you can barely see the brightest stars and the moon. Where not to see the solar eclipse of August 2026 And it does not only affect large cities (in Madrid it can be seen from quite a few kilometers away), but also industrial areas and ports. In these cases, it is also usually permanent lighting without any control. Also the road networks. A picture is worth a thousand words: the map by cartographer and geospatial developer Jacob Wasilkowski and Petrichor Studio called Earth at Night. Earth at night. JWasilGeo & Petrichor Studio This map combines several sources: night light data comes from NASA (Suomi-NPP satellite, VIIRS sensor) and background satellite mapping is provided by Earthstar Geographics along with other commercial providers integrated into Esri’s World Imagery service. The technological infrastructure to render it in 3D is also from Esri, a Californian company specialized in GIS software. Wasilkowski is the one who has put it all together to convert luminosity into topography. Simply put: It has converted the luminosity of NASA’s nighttime images into elevation, so that cities are mountains. The bigger the city, generally the bigger and higher the mountain will be. Note that there are areas, such as northern Italy or the German border with Belgium, that are real garlands. In the Iberian Peninsula, the Mediterranean coast, the Portuguese coast and a point in the middle of everything stand out: Madrid. These are the areas to escape from if we want to see the sky well. Earth at night. JWasilGeo & Petrichor Studio And just the opposite, the valleys are the most interesting areas to observe the eclipse or any other astronomical milestone: they are the dark areas. Although its controls are intuitive, you have options to switch to the satellite layer, you can zoom, pan and rotate. The map is a few years old now, but for those of us who like to observe the sky it is a good idea to always have it at hand. Furthermore, when this map was launched a decade ago it had a great impact on the cartographic community, winning the award GOLD from the KANTAR Information is Beautiful Awards 2019 in the category “Maps, Places and Spaces”, under the name “Earth at Night, Mountains of Light”. And why not say it: it is evocative. After all, it uses real light captured from space to re-sculpt the Earth, letting it be human activity that defines its topography.

The entire ocean floor of the Earth, in a spectacular 3D interactive map that reveals 50,000 unknown underwater mountains

by

Although we are already looking other planets in the universe (especially interesting are the potentially habitable ones), the reality is that the old Earth still has a few hidden secrets left. Without going any further, the seabed continues to delight us with new species at this point in the film. NASA knows this and that is why in December 2022 it launched a satellite into space with a mission: to achieve topography of surface waters and oceans. Hence its name, SWOT. Already the first year managed to map the ocean floor in more detail than in the last 30 years and is now available in full. It is, in short, the most detailed marine gravity map in history. What he has “seen” is not just the ground, but subtle variations in the height of the sea surface. These variations reveal the existence of thousands of underwater mountains, trenches and faults, invisible to conventional satellites. To prepare this map, NASA has used state-of-the-art phase coherence interferometry, which has made it possible to measure the two-dimensional height of sea level with high precision. Historically, sonar has been used to measure the seabed, but we have only managed to map less than 30% (with the Seabed 2030 project) with this technique. On the other hand, standard satellites offered a resolution well below the achieved spatial resolution, close to 8 kilometers. This exhaustive map of the ocean floor goes beyond satisfying geographical curiosity, the impact of this cartography It is evident in: Biodiversity. Underwater mountains are oases of life and knowing where they are is essential. Safety in navigation, allowing the identification of underwater peaks that may constitute a risk for vessels. Climate change. These types of structures are directly related to ocean currents, responsible for transporting heat. If we do not know the relief, we cannot predict how the sea will warm. The map of the seabed with a level of detail never seen before With this vertical gravitational gradient map, NASA has developed a 3D model through which you can move and zoom through all the depths of the seas and oceans of the Earth. Individual abyssal hills measuring 200 – 300 kilometers in length can be seen along with other small seamounts and tectonic structures, previously hidden. In fact, abyssal hills are the most common landform underwater (in the southern Indian Ocean they can be seen, for example). NASA explains that they are formed by normal faults along the axes of the oceanic ridges. From them, plate reconstruction studies are being carried out. Also in the visualization you can see seamounts located west of Central America, which are actually underwater volcanoes formed by magmatic intrusions through the oceanic crust. Their importance is crucial as they modify ocean circulation, influence the distribution of nutrients and constitute key points of biodiversity. The high-resolution mapping reveals some 50,000 previously unknown seamounts approximately one kilometer high. Tap to go to NASA’s 3D model of the seafloor. Via: NASA/JPL The topography of surface waters and oceans from SWOT also shows great clarity in the continental margins, highlighting the high latitude areas, with tectonic structures buried under sediments and ice. Thus, it allows observing submarine canyons that transport sediment from the mainland to the deep sea along the South American continental shelf, as well as ancient mid-ocean ridges hidden under the ice in the Weddell Sea.

The map of Spain’s exports, a much more industrial country than you think

by

In a global world but with tariffs where China is the factory of the world and Germany is the engine of EuropeIt is easy to fall into historical clichés when we talk about the Spanish state and the great Mediterranean classics such as olive oil, ham or wine, but the reality is that Spain exports many more products to the world. Yes, those typical ones appear on the list, but there are other less known ones that are ahead. And if we open the range to products and services, we cannot miss a sector in which it is a world power: tourism. He Atlas of Economic Complexity from the Harvard Kennedy School is a very useful tool from the popular Harvard University, which takes the international trade data that different states report to the United Nations to display them in a single graph after cleaning them with the Bustos-Yildirim method. It includes data from 250 countries and territories, classified into 20 categories of goods and five categories of services, covering more than 6,000 products. The result is an x-ray of what Spain sells to the world and what it reveals does not always coincide with the image we have. The last period of time collected by the Atlas of Economic Complexity is 2024, where we see that the Spanish state exported 590,000 million dollars in more than a dozen sectors. And there is a clear dominant: the service sector. What does Spain sell to the world? 2024 Edition. Harvard Atlas of Economic Complexity Travel and tourism takes over the top left corner, worth $107 billion. It is pure tourism: according to the World Travel & Tourism Councilthat is the spending of international tourists within the territory, 10.9% more than the previous year. It is followed by a generic “Business” and if we take into account other pink portions such as insurance, financial services, transportation or the mixed bag of “Not specified”, we find that this pink band of services is 163,000 million dollars of the total, that is, Services account for 28% of everything that Spain exports. There is life beyond services The second largest rectangle on the graph corresponds to cars, with a value of $37.1 billion. It’s in the upper right corner, in purple: the car is also the first manufactured productbut in third place and well behind two categories of services. As we saw in this map of the European automobile industrythe gold of the sector in the old continent belongs to Germany, but Spain takes the silver, with a share of 16.4% and almost two million cars assembled per year. Next to it is the rectangle of engine parts, with 10,000 million dollars. However, if we add the set of cars, parts and commercial vehicles, the set adds up to about 65 billion dollars. That is to say, that automotive is the second sector that Spain exports the most. From this point on the difference is no longer so much and in fact it can be divided into two. On the one hand and in pink, the chemical block, with medicines as the most prominent industry (more than 12,000 million dollars). The total is around 37 billion dollars. Yellow corresponds to food, which together represents about 45 billion dollars. Here exports are scattered with pork, olive oil, wine or citrus being the most relevant. Outside of these sectors, the most notable is petroleum and refined oil, with just under 9 billion dollars and below 3%. Minerals, machinery, metallurgy, electronics or textiles have even less influence. A global and deeper reading of the map makes it clear that Spain is, in terms of exports, a tourist and agri-food power with a notable automobile and chemical industry. Dependence on tourism is a double-edged sword in that it allows us to take advantage of Spain’s competitive advantages, but at the same time it depends on external factors, such as COVID or emerging markets that can absorb demand with lower prices. And although it is money that comes in without the need to manufacture anything, it does not add complexity: there are no patents or exportable technologies. Furthermore, the quality of employment is lower than other sectors. In short, it is a structural issue: no rich country sustains itself by selling good weather and that is the best invitation to reindustrialize.

This map of the August solar eclipse is a gem for discovering where and how to see it best

by

Those of us who love to look at the sky in search of astronomical landmarks are in luck: the classic summer Perseid shower is joined by the first of the three eclipses planned between 2026 and 2028that of August 12. It will be a historic event in that it will be the first total eclipse visible on the peninsula since 1912. There is still time to find a good place free of light pollution (or at least, not “light pollution dump“) close to where we are. That is, if we are lucky enough that the solar eclipse is full wherever we are. Taking into account that it will be in the middle of August, surely there are those who are preparing a getaway to a potentially ideal location. In addition to finding a place where the eclipse is total and free of buildings and streetlights, if we want to enjoy the solar eclipse in its maximum splendorthere are other aspects to take into account, such as whether the shadows will bother us or how long it will be visible. The National Geographic Institute has a section on your website where to monitor in which parts of the world the solar eclipse will be seen and which areas will be partial and which will be total. Thus, we hope to see it in North America, much of Europe and West Africa. Where to best see the total solar eclipse, on an interactive map But it will only be total in a relatively wide strip, the one you see in the dark that crosses the Arctic Ocean, the northeast of Greenland and the extreme west of Iceland, crossing the Atlantic Ocean to enter the Iberian Peninsula. The time when the eclipse will be at its maximum It will be at 19 hours and 46 minutes (peninsular time) and at that point on the planet (near Iceland) it will last at most two minutes and 18 seconds. Where the solar eclipse will be seen: areas where it will be total and areas where it will be partial. IGN The total eclipse will cross the Iberian Peninsula from west to east from A Coruña to Palma, passing through cities such as Lugo, Oviedo, León, Zamora, Valladolid, Palencia, Segovia, Burgos, Soria, Santander, Bilbao, Vitoria-Gasteiz, Logroño, Guadalajara, Cuenca, Zaragoza, Teruel, Lleida, Tarragona, València and Castelló de la Plana. In Spain, the local maximum will occur around 8:28–32 minutes, and totality will last up to 1 minute and 50 seconds at the point of longest duration (the Asturian coast). Madrid and Barcelona are outside the strip: although they will see a visually impressive 99% partial eclipse, it will not reach the point that will be seen in the strip. This IGN interactive map It has an animation where you can see the progress of the shadow that will form the superimposition of the moon on the sun. The shadow of the solar eclipse, in an animation If you are interested in having more precise information about a specific location, it includes a box where you can enter addresses or cities, which opens the doors to having data such as its visibility profile, duration, when it will start, its peak point or the time you will be able to see it. Eclipse data for Estella – Lizarra. IGN On the right side it has several options such as sharing information, background layers for example the satellite view or a particularly interesting one: layers. Thus, you can activate the duration to know in which areas you can enjoy more viewing time, the degree of obscuration or visibility, because you could go out into nature to see it without being bothered by the lights and discover that the shadows of the terrain disturb your vision. The interactive map, with visibility, darkness and duration layers activated. IGN An important detail for choosing the site: The eclipse will occur at sunset, with the sun low on the horizon, which will require observing it in a place that offers good visibility to the west, without mountains, buildings or trees that obstruct. On the other hand, remember not to look at the sun directly except during that period when the eclipse is total. But it’s better not to risk it and use approved glasses.
