The results indicate that despite catastrophic calvings such as those from the Amery, West, Bellingshausen, and Thwaites ice shelves, involving a total of about 20,000 km2 of ice, the total area of the Antarctic ice shelves during this 20year period increased by 135,000 km2 or by 9 ...

阅读理解In Antarctica, about 12.3 million km of its area are covered withice. At present, this continent holds about 26.5 million km3 of ice.However, nearly one-fifth of the total Antarctic ice sheet(冰盖) surfacehad experienced observable melting(融化) during the past two decades(1999-2019)...
The long bloom at SOI seems to drive considerable carbon immobilization, but sea-ice losses across West Antarctica mean that significant carbon sinks and negative feedbacks to climate change could also develop in the Bellingshausen and Amundsen seas. 展开 ...
A continent is defined by being a large continuous area of land that is generally separated by a body of water. Continents are made up of many countries and have millions and in some cases billions of people that call it home. There are 7 continents on planet Earth: Africa, Antarctica, ...
In analysing the occupation of wetland areas by ISA expansion on an intercontinental scale, Antarctica was not considered in this study because of the small population and unique geographical environment. And almost no artificial impervious surface and wetlands existed. Inter-annual changes in wetland ...
The area covered by permafrost in Antarctica is ca. 13.9 million km2, that is its entire surface. This result was also made possible due to the first clear determination of the boundaries and area of the continent. The Antarctic area includes (a) rocky subsurface with (b) continental ice鈥...
AntarcticaPleuragramma antarcticum is the dominant pelagic fish in the waters of the continental shelf in high Antarctic regions, where it plays a key role in the food web. A nursery ground for eggs of this species was first identified in 2002 in Terra Nova Bay (Ross Sea), where eggs ...
