Accumulation (Standard and Compact)

An ultra-wideband radar that maps internal layers in the upper few hundred meters of the ice sheet and sounds shallow ice caps and ice shelves. It has also been shown to measure the bottom melt rate of ice shelves, and it demonstrates the potential to measure thick snow on sea ice and sound sea ice thickness.
