Seasonal 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 ...
متن کاملSediment 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 کاملSeasonal climate information preserved in West Antarctic ice core water isotopes: relationships to temperature, large-scale circulation, and sea ice
As part of the United States’ contribution to the International Trans-Antarctic Scientific Expedition (ITASE), a network of precisely dated and highly resolved ice cores was retrieved from West Antarctica. The ITASE dataset provides a unique record of spatial and temporal variations of stable water isotopes (dO and dD) across West Antarctica. We demonstrate that, after accounting for water vapo...
متن کاملDetecting Surface Melt of Antarctic Ice-sheets Using Scatterometers
The SeaWinds on QuikScat and ERS-1/2 scatterometers measure the radar response of the Earth’s surface with high spatialand temporal-resolution. The data collected by these space-borne active-microwave sensors are used to detect periods of surface melting in the Antarctic iceshelves. A description of a statistical melt-detection algorithm is given and the results are shown and compared to other ...
