2020年7月2日,南京师范大学生命科学学院钟伯坚教授研究组联合自然资源部第一海洋研究所缪锦来研究员课题组在Current Biology发表了题为Adaptation to Extreme Antarctic Environments Revealed by the Genome of a Sea Ice Green Alga的研究论文,对南极海冰生态系统特有的南极衣藻进行了基因组适应性进化研究,揭示了南极嗜冷...
Sea level riseThe Antarctic Circumpolar Current (ACC) provides fundamental control on the Antarctic ice system. The tilt of the isopycnals of the ACC, in response to strong westerlies, serves to thermally isolate the Antarctic continent from directly receiving the overwhelming subtropical ocean surface...
Most of the deep water acquires its characteristics in the Antarctic region and in the Norwegian Sea. Antarctic bottom water is the densest and coldest water in the ocean depths. It forms and sinks just off the continental slope of Antarctica and drifts slowly along the bottom as far as the...

②King penguins are the second-largest type of penguin and only breed on specific isolated islands in the Southern Ocean where there is no ice cover and easy access to the sea. ③As the ocean warms, a body of water called the Antarctic Polar Front—an upward movement of nutrient-rich ...
With Atlas Ocean Voyages (USA) the ship operates mainly in Europe (Mediterranean Sea, Atlantic Coastal, Baltic Sea, Norwegian Fjords), Iceland and Greenland. During winter months, the ship operates on polar cruises - toAntarcticand Arctic destinations. Atlas Ocean Voyages is a fully-owned subsidi...

(EU Copernicus Marine Service) over the period 2000–2008. Consistent with previous studies (e.g.,1), Western Boundary Currents (WBC) and the Antarctic Circumpolar Current (ACC) are the most eddy active regions (Fig.1). Eastern Boundary Currents, although less active, have relatively highEKE...
Moreover, changes in ACC strength on the glacial-interglacial timescale correspond to the sea salt sodium (ssNa) flux record from the East Antarctic Dronning Maud Land (EDML) ice core (Fig. 2e–g), a proxy partially related to large-scale sea ice production34. This indicates that major ...
climate change, the researchers said. The absence of polynyas in recent decades could mean that heat is getting trapped in the deeper ocean, possibly contributing to the recent "hiatus" in global atmospheric warming and the increase in Antarctic sea ice extent that have been observed in recent ...
