Measurement of sea ice thickness and subice morphology in Arctic Ocean using ice penetrating radar
Listed in NASA Earthdata CMR
During the first Chinese Arctic Scientific Expedition between July and September in 1999, a ground radio-echo sounding survey was carried out, using a new type of ice penetrating radar system with antenna center frequencies of between 100 and 200 MHz, for detecting the sea ice thickness in the Arctic Ocean.
Description
In addition, the radar sounding yielded a subtle morphology on the bottom of the sea ice in the summer in the Arctic Ocean.
