Earth's oceans are a complex system, and their interconnected nature has global implications. Around Antarctica, cold and dense waters form in the depths of the Southern Ocean. This is known as Antarctic Bottom Water (AABW). ...
Over the past three decades, the depths of the Antarctic Weddell Sea have warmed five times faster than the rest of the ocean at depths exceeding 2,000 meters. This was the main finding of an article just published by oceanographers ...
