B 046 M: The biogeochemical evolution of dissolved orga...

Dissolved organic matter (DOM) is an important component of the global carbon cycle and provides a carbon source for microbial activity. Much of this carbon pool is composed of predominantly recalcitrant organic matter derived from microorganisms (most gl ...

B 332 M: Distinguishing biotic and abiotic nitrous oxid...

The project will examine nitrous oxide dynamics in Antarctic environments through the collection and examination of soil and water/brine samples. The goal of the work is to conduct a systematic study of nitrous oxide emissions in contrasting habitats to d ...

G 074 M: Collaborative Research: Activation of high ele...

The western Olympus Range is an east-west oriented mountain chain in the west-central Dry Valleys, dividing upper Wright Valley and McKelvey Valley. Our previous work in the range focused on well-preserved sequences of tills and fossil-rich proglacial lak ...

G 085 M: Collaborative Research: Multinuclide approach ...

During the past two decades, exposure dating of bedrock surfaces and glacial deposits has been used throughout Antarctica to expand scientific understanding of past ice-sheet fluctuations and to quantify average long-term weathering rates. Notwithstanding ...

G 294 M: Collaborative Research: Integrating geomorphol...

Ancient lake sediments deposited on the margins of former outlet and alpine glaciers in the Dry Valleys region are proving to be an invaluable archive for studies of past climatic and ecological changes. Using a numerical chronology based on analyses of i ...

G 298 M: Resistivity mapping of subsurface microbial ha...

The McMurdo-SkyTEM project aims to map subsurface resistivity using the Time Domain Electromagnetic (TEM) method, which offers a non-invasive and efficient way to determine the subsurface distribution of water salinity, hydrogeologic connectivity, buried ...

K123: Antarctic soils

Our Antarctic-wide Environmental Domains has been formally adopted by the Committee for Environmental Protection (CEP) as the environmental classification framework for the Antarctic continent. Within this framework Antarctica New Zealand (AntNZ) requires ...

O 283 M S: Collaborative Research: Antarctic Automatic ...

This continuing project, now in its 30th year, is the largest in the Antarctic and has the broadest spatial coverage, with a network of automatic weather stations (AWS) on the Antarctic continent and several surrounding islands. These facilities measure s ...

O 324 M: Augmenting the Ross Island area automatic weat...

The Antarctic troposphere has the least anthropogenically influenced surface air on Earth and presents a unique opportunity for the study of naturally occurring processes that control the chemical composition of our atmosphere. Of particular interest to t ...
