C-band and Ramac Shallow Radar Profiles Troll Station - South Pole (IPY 2007-2008)
The shallow radar measurements were made to obtain accumulation rates from the variation in depth to internal layers, and their lateral and temporal variability along the traverse route. The data were also collected for back-scatter comparison of the ground penetrating radars (GPR) and synthetic ape...
