Submarine mountains and long-distance waves stir the deepest parts of the ocean

The deep ocean is not a silent, static place – it’s active, connected to the oceans above and always changing.

Line graph showing the daily sea-ice extent for the Arctic. 2025 is shown in the black-white line up until 2025-11-26, while the previous years of yearly minimas (2012, 2020) and minimum of this time of year (2016) are presented in red, blue, and orange, respectively. The extent in 2025 has just become record low for this time of year. Data source is the OSI SAF sea-ice index v2.3.

Arctic sea-ice extent just passed the border into the "record-low" domain.
Same for Barents, Baffin, Hudson, and Svalbard regions.
Second-lowest globally.

Sea level doesn’t rise at the same rate everywhere – we mapped where Antarctica’s ice melt would have the biggest impact Understanding what happens to Antarctica’s ice matters, because as it melts, sea levels rise, affecting lives and economies around the world.
