A group of researchers led by David Ambassus from the University of Barcelona and Ricardo Arozio from the University College Cork (Ireland) has published an extremely detailed map of underwater guns in Antarctica, which is the most accurate today. According to a study in the magazine Marine Geology, the card It includes 332 submarines, which in some cases reach a depth of 4000 meters. These guns, which are of great importance for the oceanic dynamics and climate change, are found in the remote areas of the Antarctic continent, the geological characteristics of which are largely unknown.
Underwater guns are natural formations that connect deeper areas with coastal areas, transporting the necessary deposits and nutrients. Although its environmental and geological value is huge, very little studied, especially in polar regions, and Only 27% of these guns were displayed worldwide. In Antarctica, these guns are not only larger and deeper from the action of ice and transportation of deposits with glaciers, but also have a crucial role in global changes, as they affect ocean circulation and thawing floating ice platforms.
Amblàs notes that Antarctic guns, especially in the eastern region, are more complex and branched, with large distance systems, while those in the western zone are usually shorter and more steep. In addition, researchers have created A specific code To process the guns and calculations of various geomorphological parameters, which made it possible to more accurately analyze.
These guns play an important function, allowing the exchange of cold and thick waters with the depth of the ocean, which affects both the global climate and the thaw of ice platforms in the region. This phenomenon is key to Understand how climate change can accelerate the sea level increase.
