A team of National Science Foundation (NSF)-supported researchers at the Virginia Polytechnic Institute and State University (Virginia Tech) discovered new evidence about how the Earth's magnetic fiel...
Sea-level rise from Antarctic ice sheet could double
Sea-level rise Antarctic ice sheet double
2016/4/13
An ice sheet model that includes previously underappreciated processes indicates that sea level may rise almost 50 feet by 2500 due to Antarctic ice sheet melting if greenhouse gas emissions continue ...

Severe declines in megafauna worldwide illuminate the role of top predators in
ecosystem structure. In the Antarctic, the Krill Surplus Hypothesis posits that the killing
of more than 2 million larg...
The anticipated melting of the massive West Antarctic Ice Sheet could be slowed by two big factors that are largely overlooked in current computer models, according to a new study.The findings, publis...

The U.S. National Science Foundation (NSF) has agreed to support the development of a new generation gravity map of Antarctica (ADGRAV - Antarctic Digital Gravity Synthesis), funding the development o...
Improved compilationof Antarctic Peninsula magnetic data by new interactive grid suturing and blending methods
Aeromagnetic grid compilation GridKnit™
2015/10/8
The utility of aeromagnetic and other geoscientific compilations on a range of scales, is well established for a wide variety of geological investigations. Aeromagnetic compilations, currently underwa...
Mapping and interpretation of satellite magnetic anomalies from POGO data over the Antarctic region
Antarctic geomagnetic field magnetic field satellites magnetic anomalies
2015/10/8
A satellite magnetic anomaly map made using the POGO magnetic field data is compared to three maps made using Magsat data. A total of 14 anomalies with magnitudes greater than 3 nT can be identified i...

About 40 000 km of marine magnetic and gradiometric data have been collected during eight geophysical surveys conducted since the Austral summer 1987/1988 in the circum-antarctic seas, by the research...
Warming Antarctic waters may allow king crabs to "restructure" ecosystems
Warming Antarctic waters king crabs restructure ecosystems
2015/10/13
Rapid warming of the ocean west of the Antarctic Peninsula--the part of the continent that extends north toward South America--makes it possible king crab populations could return from the deep sea to...
Quasi-parabolic reflecting bottom surfaces of the Drygalski Antarctic floating ice tongue
radio echo sounding radio glaciology glacier ice tongues
2015/9/28
Very high frequency deep radio sounding systems for ice thickness measurements are practically the only useful apparatuses for large scale radar flight surveys in polar regions. The morphology of the ...
