C 457: Assessing Changing Patterns of Human Activity in...

We will be conducting repeat photography of sites of human occupation in the McMurdo Dry Valleys in order to build a digital photo archive of the region. Historical photos are being collected from archives and individuals in the United States and New Zeal ...

C 509 M: McMurdo LTER Geochemistry Increased Connectivi...

Initially funded in 1980, the US Long-Term Ecological Research (LTER) Network is a collaborative effort involving more than 1,800 scientists and students. The McMurdo LTER program is an inter-disciplinary and multi-disciplinary study of the aquatic and te ...

C 517 M: The McMurdo Dry Valleys A Landscape on the Thr...

Rapid landscape change has been observed in the McMurdo Dry Valleys during the past decade. Increased solar radiation is hypothesized to cause surface sediment warming and subsequent rapid melting of ice in areas where sediment is in contact with ice. Sur ...

G 054 M: West Antarctic Ice Sheet Stability, Alpine Gla...

This project will develop high-resolution maps of drifts deposited from grounded marine-based ice and alpine glaciers on islands and peninsulas in McMurdo Sound. In addition, the researchers will acquire multi-clast/multi-nuclide cosmogenic analyses of th ...

G 063 M: Microbialite Morphology in Lake Joyce, Antarct...

Researchers will characterize microbial mats that are growing on the floor of Lake Joyce. Previous results demonstrate that these mats are morphologically similar to fossil mats that are 2.5 to 3 billion years old in diverse locations around the globe. Th ...

G 076 M: Petrologic Constraints on Subduction Terminati...

Rocks highly enriched in potassium such as lamprophyres potentially provide direct insight into of foundering and the processes that occur during, and immediately after, termination of subduction. These enigmatic rocks are important because they represent ...

G 078 M: Dry Valley Seismic Project

The Dry Valleys seismic project monitors regional and global seismicity. The Dry Valleys stations are part of the Air Force Technical Applications Center’s (AFTAC) southern network, which accumulates near-real-time data from nine locations in the southe ...

G 085 M: Origin and climatic significance of rock glaci...

Rock glaciers are common in the McMurdo Dry Valleys, but they are concentrated in a few isolated regions: western Taylor Valley, western Wright Valley, Pearse Valley and Bull Pass. The researchers hypothesize that the origin and age of these features vari ...

K001 1516 D: Sampling of Nunataks on Mawson Glacier

The overall goal of this work is to understand the retreat of Antarctic ice sheets during the last deglaciation (20,000 years ago to present). During this period the East and West Antarctic Ice Sheets receded from advanced positions at the continental she ...

K123 1516 B: Climate Weather Stations

The overall goal of our research is the development of an environmental classification specific for the Ross Sea region using environmental domains analysis (RSR EDA). We will fill key data gaps needed to deliver the RSR EDA, by: producing a soil map of t ...
