B 012 M: Collaborative Research: Importance of heterotr...

Study of 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 N2 fixing communities. Ultimately, w ...

B 247 M: CAREER: Protist Nutritional Strategies in Per...

The overall objectives of this project are to understand the metabolic versatility of single−celled eukaryotic microbial (protist) species residing in McMurdo Dry Valley (MDV) lakes and link protist trophic strategy with specific abiotic drivers (eg: te ...

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

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 that the wi ...

C 505 M: McMurdo LTER Lakes: Increased Connectivity in ...

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 ...

C 506 M: McMurdo LTER Streams: Increased connectivity ...

This project is the “streams” component of the MCM LTER. Researchers operate a network of 18 stream flow gages, collect water quality samples from over 30 streams, and make hydrologic measurements.

C 507 M: McMurdo LTER Soils: Increased Connectivity in ...

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 ...

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

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 ...

C 511 M: McMurdo LTER Lakes: Increased Connectivity in ...

The primary focus of the physical limnology and meteorology of the McMurdo Dry Valleys. Goals include (1) long term automated lake monitoring (to measuring parameters such as light levels, temperature, ice thickness, continuous lake level and ablation; (2 ...

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

The purpose of the work is to evaluate the range of changes occurring in the Dry Valleys and subsequent impacts on biological, glaciological, and hydrological systems using airborne LiDAR measurements and supporting ground analyses.

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

Characterize microbial mats that are growing on the floor of Lake Joyce, Pearse Valley, McMurdo Dry Valleys, and develop a model for biological, sedimentological, and geochemical processes that influence microbial mat morphology and use that model to help ...

K020: Assessing and validating biometrics for change: E...

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

K024: Invertebrates on the edge: Assessing Mackay Glaci...

Transitions naturally occur between one ecosystem type and another such as along shorelines of oceans, or at forest edges. These transitions are called ‘ecotones’ and are ideal for studying the physical, chemical and biological responses to climate ch ...

K082: Impacts of changing environments: Ross Sea coast...

"Anthropogenic impacts in Antarctica are increasing and a good understanding of marine ecosystem function is needed to inform decisions on environmental management and protection. With a focus on coastal benthic (seafloor) communities and the environmenta ...
