- Antarctic Ice Sheet Velocity and Mapping Project (AIV)
The Antarctic ice sheet is a continental glacier covering 98% of the Antarctic continent, with an area of 14 million square kilometres (5.4 million square miles) and an average thickness of over 2 kilometres (1.2 mi). It is the largest of Earth's two current ice sheets, containing 26.5 million cubic kilometres (6,400,000 cubic miles) of ice ...
13 gru 2019 · University of California, Irvine-led team releases high-precision map of Antarctic ice sheet bed topography. New findings will help scientists predict climate change impact on frozen continent.
AIV products use state-of-the-art techniques in mapping ice sheet velocity from space. The results are independent of cloud cover and solar illumination, and offer a uniform, high-resolution sampling of the entire Antarctic continent.
Based on U.S. National Ice Center's Antarctic daily and weekly analyses, various ice charts are produced to represent ice conditions in a graphical format. Ice conditions are based on ice concentrations, stage of development (ice type / thickness), and 30 day ice concentration changes.
The East Antarctic Ice Sheet ( EAIS) lies between 45° west and 168° east longitudinally. It was first formed around 34 million years ago, [3] and it is the largest ice sheet on the entire planet, with far greater volume than the Greenland ice sheet or the West Antarctic Ice Sheet (WAIS), from which it is separated by the Transantarctic Mountains.
The Antarctic Ice Sheets ECV project develops methods for producing long-term and reliable climate data records of Antarctica from satellite observations, and distributes these records for use by the wider scientific community.
