Antarctic waters reveals Ross Ice Shelf melts summer
2019/10/22
A new paper by NSF-funded researchers at the Earth Institute at Columbia University offers fresh insights into the forces causing the world's largest ice shelf to melt.The Ross Ice Shelf, a part of th...
APPLICATION OF MULTISPECTRAL SATELLITE DATA FOR GEOLOGICAL MAPPING IN ANTARCTIC ENVIRONMENTS
Multispectral satellite data Geological mapping Antarctic environments
2016/10/14
Remote sensing imagery is capable to provide a solution to overcome the difficulties associated with geological field mapping in the Antarctic. Advanced optical and radar satellite imagery is the most...
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...

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...

2015/10/8
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...
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 ...
