Sediment Melt-Migration Dynamics in Perennial Antarctic Lake Ice
We examined sediment melt-migration dynamics in the ice cover of Lake Fryxell, Taylor Valley, McMurdo Dry Valleys, Antarctica, using a combination of laboratory experiments, field observations, and modeling. The specific objectives were to determine the thermal conditions required for sediment melt and how sediment migration rates vary with meteorological forcings and ice microstructure. These ...
متن کاملPerennial Antarctic lake ice: an oasis for life in a polar desert.
The permanent ice covers of Antarctic lakes in the McMurdo Dry Valleys develop liquid water inclusions in response to solar heating of internal aeolian-derived sediments. The ice sediment particles serve as nutrient (inorganic and organic)-enriched microzones for the establishment of a physiologically and ecologically complex microbial consortium capable of contemporaneous photosynthesis, nitro...

متن کاملMicroplankton dynamics in a perennially ice-covered Antarctic lake – Lake Hoare
1. Temporal and spatial variation in planktonic abundance, biomass and composition were determined in Lake Hoare (McMurdo Dry Valleys, Antarctica) over two summer seasons (1996–97 and 1997–98). 2. Phototrophic nanoflagellates (PNAN) dominated planktonic biomass, with a mean monthly biomass ranging between 27.3 and 40.4 lg C L. The deep chlorophyll maximum was mainly composed of cryptophytes (>8...
متن کاملSeasonal to interannual variability in Antarctic sea-ice surface melt
Satellite remote sensing time-series images are used to illustrate the spatial and temporal variability in Antarctic-wide seaice surface melting during the austral summer. Combinations of collocated data from the Active Microwave Instrument on board the ERS-1/2 spacecraft, RadarSat Synthetic Aperture Radar (SAR) and SSM/I passive microwave radiometer are used in characterization of the effects ...
