Current Trends in Antarctic Sea Ice: The 1990s Impact on a Short Climatology Antarctic sea ice extent, open water area, and ice area are shown to have increased significantly during the period 1987–96. These trends are largely attr... AB Watkins,I Simmonds - 《Journal of Climate》 被引量...
Oceanographers have noticed that Antarctic Bottom Waters, a massive current of cold, salty and dense water that flows 2,000 meters under the ocean's surface from near the Antarctic coast toward the equator has been shrinking in recent decades. This is cause for concern, as the current is bel...
In the summer of 2023, four alarming global climate records were broken: the hottest day on record globally; the hottest June on record; the warmest global ocean temperatures in May, June, and July; and the lowest recorded level of Antarctic sea-ice. One could not turn on the television ...
Obs.). Large numbers of post-breeding male Antarctic fur seals also use the waters of the southern Scotia Arc. Other marine mammals which were not hunted (or only lightly hunted), but which also consume krill are also present across the southern Scotia Arc, including leopard seals (Hydrurga ...

Differences between these models, as well as observed changes in NPP6,7,11 have mainly been related to the specific physical conditions of the Arctic Ocean, such as sea-ice extent and ocean circulation. However, recent studies have suggested that terrigenous nutrient inputs from rivers and ...

We propose that Antarctic sea ice extent, together with wind changes, acted as a positive feedback mechanism on increasing amplitudes in millennial-scale ACC strength towards the LGM. Sea ice effectively moderates the momentum transfer of wind-derived energy into the surface ocean5,16, because the...
