Scientists set expedition investigate Iceberg Alley Antarctica
2019/11/22
The 5.4 million-square-mile Antarctic Ice Sheet is the greatest mass of fresh water on Earth. If it all were to melt, it would raise global sea levels some 220 feet. Searching for answers to how fast ...
Radio Echo Sounding (RES) investigations at Talos Dome (East Antarctica): bedrock topography and ice thickness
radio echo sounding radio glaciology ice thickness measurements
2015/9/17
Radio echo sounding measurements were collected during two Antarctic expeditions to determine the ice thickness
and the sub-glacial morphology of Talos Dome in the region around 72°48'S; 159°06'E (ab...

Tills for this study were analyzed from sites in East Antarctica (EA), West Antarctica (WA) and along a transect in the Ross Sea. Particle size, sand petrography, and detrital zircons were used to pro...
Geochemical characteristics of meltwater and pondwater on Barton and Weaver Peninsulas of King George Island, West Antarctica
chemical compositions of meltwater and pondwater sea salt water-rock interaction King George Island Antarctica
2017/4/11
In Antarctica, the geochemical properties of meltwater and pondwater are very sensitive to global warming. Therefore,
understanding the geochemical properties of the meltwater and pondwater is crucia...
Trace element and isotopic evidence for temporal changes of the mantle sources in the South Shetland Islands, Antarctica
trace elements Sr-Nd-Pb isotopes subduction component heterogeneous mantle South Shetland Islands
2017/8/10
We present Sr-Nd-Pb isotope data from the Paleocene-Eocene volcanic rocks in King George Island, South Shetland Islands, West Antarctica. The initial isotopic ratios of the analyzed samples display li...
