B 504 M: Glaciers: Increased Connectivity in a Polar D...

This project is the “glaciers and meteorology” component of the MCM LTER. Researchers will continue measurements of physical properties of dry valley glaciers and meteorology, with special emphasis on LTER core research areas.

B 505 M: Lakes: Increased Connectivity in a Polar Deser...

This project is the “Lakes 1” component of the MCM LTER. Researchers will continue their long term measurements of biological, chemical, and physical limnological properties of dry valley lakes and lake ice, with special emphasis on LTER core research ...

B 506 M: Streams: Increased Connectivity in a Polar Des...

This project is the “streams” component of the MCM LTER. Researchers operate a network of 16 stream flow gauges, collect water quality samples from 30 streams, and make hydrologic measurements. ntinue to measure lake levels at Lakes Joyce, House, Vid ...

B 507 M: Soils: Increased Connectivity in a Polar Deser...

This project is the “soils” component of the MCM LTER. Researchers maintain (through application of water and nutrients), monitor (soil moisture and temperature) and sample (soils) in their long-term experimental plots near Lakes Fryxell, Hoare and Bo ...

B 509 M: Geochemistry: Increased Connectivity in a Pola...

This project is the “geochemistry” component of the MCM LTER. Researchers monitor the inorganic geochemistry of waters and solid samples collected from the glaciers, streams, ponds, lakes and landscape of the Dry Valleys. They continue to study the up ...

B 511 M: Lakes: Increased Connectivity in a Polar Deser...

This project is the “Lakes 2” component of the MCM LTER. Its primary focus is the physical limnology of the McMurdo Dry Valley lakes. This year’s goals are to (1) To upgrade and maintain long-term automated lake monitoring equipment; (2) Carry out m ...

G 054 M: Quantifying surface processes above buried ic...

Buried glaciers of the McMurdo Dry Valleys, Antarctica (MDV) represent a potentially far-reaching archive of ancient atmosphere. Unlike relatively fast-flowing ice sheets that continually move toward margins, stagnant and/or slow-moving debris-covered gla ...

G 078 M: 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 (AFTAC) southern network which accumulates near-real-time data from nine locations in the southern ...

G 496 M: Collaborative Research: Life in a Volcanic Lan...

The record of Jurassic plant life in continental Antarctica is sparse, possibly due to tectonic and magmatic activity associated with the breakup of Gondwana and the emplacement of the Ferrar Large Igneous Province. This project will examine early Jurassi ...

I 311 M: Collaborative Research: Dating and Modeling th...

This project seeks to improve our understanding of the last deglaciation of the Ross Sea sector by developing new geochronologic constraints with in situ cosmogenic nuclides and simulating the ice-sheet recession using a state-of-the-art model of the Anta ...

K001BR2: Past Antarctic Climate and Future

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 ...

K083: Stable Carbon Isotope Constraints on Methane Sour...

Atmospheric methane, i.e. CH4, is a powerful greenhouse gas and its natural sources are strongly climate dependent. In response to anthropogenic climate change, natural CH4 emissions could therefore increase strongly, leading to further warming through hi ...

K123 Environmental Domains Classification for the Ross ...

The research develops an environmental classification for terrestrial ecosystems of Ross Sea region. The classification includes associated data and models and is underpinned by new knowledge on soil distribution, climate and microbial diversity and/or ab ...
