Full size image Conforming aeromagnetic compilation to satellite model 1) For estimating the magnetic parameters of the equivalent dipole layer, we used BiCGSTAB iterative inversion method. For the satellite data, we located the equivalent dipole layer at 30 km beneath the reference level with a hor...
Alaska may not have compared to Antarctica when it came to glaciers, but Greenland certainly did. Greenland has the largest polar ice cap next to Antarctica and the glaciers here are very active. Jakobshavn Isbræ glacier is actually the largest glacier in the Northern Hemisphere and it is ...
However, compared to other regions in Antarctica, the Southern Peninsula is rather understudied, exactly because it did not show any changes in the past, ironically. "To pinpoint the cause of the changes, more data need to be collected. A detailed knowledge of the geometry of the local ice...

Earth's past, present and future come together here on the northern peninsula of Antarctica, the wildest, most desolate and mysterious of its continents. Clues to answering humanity's most basic questions are locked in this continental freezer the size of the United States and half of Canada: ...
Cenozoic ectothermic continental tetrapods (amphibians and reptiles) have not been documented previously from Antarctica, in contrast to all other continents. Here we report a fossil ilium and an ornamented skull bone that can be attributed to the Recent
On January 22, a massive iceberg broke off from Antarctica’s (南极洲的) Brunt Ice Shelf. Scientists say the iceberg was expected to break off and the event isn’t connected to climate change. But the size of the iceberg is hard to imagine. This iceberg covers an area of about 600 squ...
