Title: Land and sea ice sructure west and south of Ross Island measured by ground penetrating radar, UAV, and helicopter EM bird
Description:
Abstract:
This data set decribes surface and volume properties of snow and ice to validate radar satellite measurements. Ground penetrating radar (GPR) at 500 and 1000GHz provides information on snow layers and thickness near the surface at two sites on the McMurdo Ice Shelf, one site at Ross Island, and on the landfast and new sea ice in McMurdo Sound. A 50MHz antenna is used to measure total ice thickness and the thickness of the ice above the saline layer underneath the ice shelf. Snow density and morphology is measured in snow pits using standard glaciological methods and an infrared camera, as well as an ice corer for depths down to about 8m. Snow stakes were used to measure the annual accumulation on land ice over a one year period. A dust layer is used to quantify the average accumulation over a 5 year period. Stake and GPR measurements suggest a high temporal and spatial variabilty in snow accumulation near Ross Island. A laser ranger on the skidoo and a small unmanned aircraft are used to determine the surface roughness of snow on land ice. For sea ice, the GPR system is used on one north south and two east-west transects to measure snow thickness on ice. Ice drilling is used to determine total sea ice thickness along the transects. A helicopter EM bird is used to measure a grid of sea ice and ice shelf thickness across the McMurdo Sound. Ground measurements validate the performance of the HEM bird in the presence of platelet ice.
