B302: IceBite: an auger and sampling systems for ground...

The goal of this project is to develop an auger and sampling tool that can be used to aseptically sample subsurface ice-cemented ground on Earth and Mars. The tool, IceBite, will be developed at NASA and then tested in the dry valleys. The dry valleys con ...

C516: Ocean surfaces on Snowball Earth

According to the "snowball earth" hypothesis, climatic changes of the Neoproterozoic time, 600-800 million years ago, included episodes of extreme glaciation, during which ice may have covered nearly the entire ocean for several million years. In tropical ...

G078: Dry Valley Seismic Project

The Dry Valleys Seismic Project monitors regional and global seismicity. The Dry Valley stations are part of the Air Force Technical Applications Center’s southern network, which accumulates near-real-time data from nine locations in the southern hemisp ...

G082: Development of Quantitative Weathering Indicators...

This Dry Valleys project is part of a larger project aimed at assessing weathering in proximal alluvial systems across a variety of climates. Researchers will collect sediment samples and compare them to parent rock compositions to determine the effects o ...

G167: Dynamics of Aeolian Processes in the McMurdo Dry ...

The spatial and temporal patterns of aeolian transport in the McMurdo Dry Valleys are not well understood. In particular, the magnitude and frequency of sediment transport events, the differences between the summer and winter transport regimes, and the fl ...

G440: Orbital Spectral Mapping of Surface Compositions ...

This research project has three main objectives: 1) establish key thermal infrared (TIR) and visible-near infrared (VNIR) spectral indices for identification of surface compositions in the Dry Valleys; 2) map distributions of primary lithologies and secon ...

K026: Improved Ability to Predict Cumulative Effects an...

There is limited understanding of cumulative impacts and recovery rates in the Antarctic soil environment. With projections of tourist numbers topping 30,000 in the next few years, concerns about cumulative impacts, and the ability of the most frequently ...

K072: Paleoclimate Reconstruction from the Terrestrial ...

Our research will derive a new terrestrial paleotemperature proxy based on the isotopic composition of pedogenic carbonate in soils of the McMurdo Dry Valleys and Darwin region of Antarctica. The proxy will allow us to test hypotheses of climatically infl ...

K123: Environmental Protection of Soils of the Ross Sea...

The goal of this research is to support environmental protection and management of ice-free areas of the Ross Sea region, Antarctica by: increasing fundamental knowledge and understanding of Antarctic soils including soil distribution and climate, bacteri ...
