Freshwater is accumulating in the Arctic Ocean. The Beaufort Sea, which is the largest Arctic Ocean freshwater reservoir, has increased its freshwater content by 40% over the past two decades. How and...
Sea ice kept oxygen from reaching deep ocean during last ice age, study finds（图）
Sea ice oxygen reaching deep ocean during ice age
2021/3/5
Extensive sea ice covered the world's oceans during the last ice age, preventing oxygen from penetrating into deep ocean waters and complicating the relationship between oxygen and carbon, a new study...
Researchers discover an immense hydrocarbon cycle in the world's ocean（图）

redefines understanding icebergs meltwaterin Southern Ocean
2021/1/8
Some icebergs that break off Antarctica are massive -- the size of New York City -- but these floating cities of freshwater have been largely ignored in climate models. A new study by scientists at th...
