Atlantic

The Atlantic has a ‘lost city’ with the key to life on other planets. Now is in danger

by

The earth seems to have no secrets at this point. That if we talk about the earth’s part, of course, because although nWe are putting the batteries With the oceanic background, much remains to be known. And one of the examples is the lost city found in 2000, a set of structures in the middle of the Atlantic that are not only curious, but they help us with the most unexpected: Study extraterrestrial ecosystems. And, ultimately, determine the clues that must be followed to find life in the universe. Only. More than 700 meters deep west of the Mesoatlantic dorsalon December 4, 2000, some explorers in command of remote control submersibles found something surprising: a set of walls and monoliths that reached 60 meters high and had a curious bluish tone due to the foci of the submarines. These carbonated structures were something that the scientific community had never seen and was baptized as the ‘lost city’. Among that we love giving rimbombant names and that could resemble Atlantis, the marketing part was already made. Chimneys. The full name is, really, ‘Hydrothermal field of the lost city’, and it is the oldest oceanic ventilation site, at least what we know. It is estimated that he is about 120,000 years old and, during all that time, his chimneys have been expelling gases at temperatures between 40 and 90 degrees Celsius. These hydrothermal vents release methane and hydrogen, but are not volcanic, so they do not produce co₂, hydrogen sulfide or metals. With the passage of the millennia, that expelled material was accumulated in the form of columns and walls of Brucita, Aragonito and Carbonate of calcium, with a whitish color and very particular schegic texture. Point of interest. For the scientific community, the lost city is a mine. Its particular environment and the conditions of its formation, as well as its age, can provide clues about the origin of life on Earth, as well as a more detailed vision of the planet’s composition. Over the years they have been studying their materials and, in 2024, a group of scientists advertisement The recovery of a rock sample more than a meter long. With her, they hope to find crucial evidence about the origin of life on earth. There are some spectacular formations. Researchers at the University of Washington described some vents as structures that “cry” fluids that form carbonated structures of multiple tips as curious as the one we see in the photo that we leave just on these lines. But there are not only rocks in the lost city. Extraterrestrials. At that depth, without oxygen, with a highly alkaline and hydrogen, methane and other gases dissolved in water, we might think that it is a ‘lunar’ ecosystem in which life is impossible. Curiously, It is full of animals such as anemones, microbial communities, crustaceans, snails and, occasionally, deep fish. The question is how life can prosper when it comes to an environment in which there is no sunlight, there is no oxygen and both hydrogen and methane, they camp their wide. That is precisely what also called the attention Of the researchers because the study of this fact can give us clues about what kind of life or signs of life to look for in environments that can be similar, such as redry or Europe (Saturn and Jupiter moons). Threatened heritage. Writing this has given me to think about ‘Avatar‘Not only because the film has attractive extraterrestrial structures, but because its director, James Cameron, is a passionate about underwater expeditions. And something that happens in his film is that we arrive at another planet and sweep it to get resources. We must not go to Pandora -the planet of ‘avatar’-, we continue to see it in areas such as the Amazon. And that we destroy the lost city is something that researchers fear. Poland got In 2018, the exploitation rights of the seabed around the lost city and, although the hydrothermal field has no valuable resources for us, altering its surroundings could endanger the entire area. That’s why you are working so that the lost city is declared a World Heritage Site with the aim of protecting it as much as possible and being able to continue studying it. We will see what happens with an area that is not the only hydrothermal field in the world, but one whose particularities can help understand how life develops in extreme conditions and in similar extraterrestrial environments.

“Festival of cycloogenesis in the middle of the Atlantic”.

Behind him Vodevil of the ‘Beast of the East’ and the anticyclonic wall last week, the thing will change radically in the Atlantic. And, in the next few days, the polar jet “He will take run“And the ocean will live an authentic”Festival of cycloogenesis“ It will only need a little luck so that this “festival” passes over Spain. “Festival of Cycogenesis”? Yes, we return to another week of creativity in terms of weather communication. However, as usual, the expression is not free: in the next few days the “anticyclonic wall” will disappear, but Blocking anticyclone in Scandinavia It will continue to entry next week. That opens a route so that, from the Atlantic, storms enter more easily. And they will take advantage of it. It is expected that, in the middle of the week, a cold air embolism will join a small storm from the Azores and will impact with the west of the peninsula. Right now, the models indicate that it will arrive weakened; But, as with these structures, it is very difficult to know what will happen until we know where exactly will be located. But that’s not the fat. The “fat” is a true turn to the country’s meteorological situation. Because shortly after, the Scandinavian anticyclone will begin to move towards Greenland and that will make LA stream current down more than usual. That can end up generating a huge storm train entering the west. In fact, today, the most likely scenario is that: the successive impact of a series of deep depressions from the Atlantic. The problem is that it remains Even too much time. That is, we do not know the details: it can be a fantastic week of water in abundance or a huge succession of storms that put in trouble in the middle country. What can we expect? Little for now. In the most likely stage, we will see how the fronts will happen throughout the week and The rain will reach the whole country (with lower incidence in the Canary Islands and the southeast of the Peninsula). For the rest, little is known: They are not clear either the temperatures or the most affected areas. Only a few days are coming and that, since The ghost of drought never abandons usIt is not bad news.

We have been fearing the arrival of the ‘Beast of the East’ a week and in the end an Atlantic front has sneaked into the squad

by

In recent days, the big topic of weather conversation has been the ‘East beast‘. Many things have been said: from Nieves generalized throughout the country to a simple decrease in temperatures. What we did not expect was the “extraordinary turn” that the situation has taken. What do we talk about when we talk about the ‘Beast of the East’? As we explained yesterdaybeyond the controversy by name, the phenomenon is very simple: a mass of polar air that takes advantage of an Atlantic blocking situation to move from the northeast of the European continent to the southwest. That is, towards us. From ‘beast’ a ‘bestiecilla’. Unlike the ‘Beast’ of 2018the mass that was approaching had no capacity to form a cold and snow storm worthy of that name. However, since these situations are rare and difficult to model, there were many doubts and uncertainties. Beyond that We were going to notice the closeness of that mass of cold airnobody was very clear about what was going to happen. The unknown is clearing. On the one hand, the mass of air has started doing something that was as far as possible: cycloogenesis. These types of masses are very dry, but on their way to the southwest they can generate cold danas or storms. On the other, an Atlantic Front It has sneaked by the northwest and is on the way to the Southeast leaving generalized rains throughout the Peninsula (less on the Mediterranean coast and the Balearic Islands). And what will happen? The interaction of the two phenomena will leave a lot of snow in the Pyrenees (already very low levels). The front will leave some water in most of the country. However, the great turn is that the instability that the front is creating will help moderate the cold peaks. That does not change the general image (it will be colder than usual), but it does make The worst forecasts are diluted Between the rain. In fact, as the front passes the temperatures will tend to rise. Be that as it may, care in the north third: snow, fog and ice will roast a few days between us.
