B 012: Importance of heterotrophic and phototrophic N2 ...

We propose to study the microbial ecology of the hyporheic and associated arid soils in various McMurdo Dry Valley systems. We want to study the biogeochemistry of these sites and the activity, composition and distribution of the N−fixing communities. U ...

B 225 M: Exploring the vulnerability of the Southern Oc...

This project will investigate the response of seals in the Ross Sea to climate change over the past several thousand years. This work follows on the PI’s recent southern elephant seals project and involves examining the population structure and paleoeco ...

B 280 M: Habitability of Antarctic lakes and detectabil...

We willl deploy autonomous instrumentation in selected lakes of Taylor Valley, Antarctica, to collect the first below−ice suite of physical, chemical and biological data during the polar night. Our proposed research will test the overarching hypothesis ...

B 330 M: An integrated ecological investigation of McMu...

Six personnel will deploy to Taylor and Wright Valleys to conduct general soil sampling and install and sample experimental plots. Plots will be established after soil surface thaw to 10 cm investigate microbial community composition and function can be m ...

B 505 M: McMurdo LTER Lakes

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 507 M: McMurdo LTER Soils

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 ...

B 509 M: McMurdo LTER Geochemistry

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: McMurdo LTER Lakes 2 - Increased connectivity ...

This project is the lake monitoring component of the MCM LTER. Our 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 (to measuring ...

G 063: Microbialite morphology in Lake Joyce, Antarctic...

Field proposal includes to: use previously collected field data and samples to quantitatively compare Lake Joyce mats to other microbial structures in Antarctic lakes as well as to Archean cuspate microbialites; and return to Lake Joyce to evaluate morpho ...

K020: Antarctic Terrestrial Ecosystems

We want to understand the processes controlling the distribution of biodiversity in ice-free areas in the Ross Sea region by biogeographically characterizing all forms of terrestrial biota for the Ross Sea region and developing an interactive model to pre ...

K081: Diving at Lake Vanda

Our programme for 2013-14 comprises collaborative, lake-based research between the NZ-supported event K081 (led by Ian Hawes, University of Canterbury) and a US-supported event (number pending, led by Dawn Sumner, University of California at Davis). This ...
