ICECAP-2 consortium processed airborne ice thickness data from the Princess Elizabeth Land, East Antarctica
Airborne ice thickness data from the Princess Elizabeth Land (PEL), East Antarctica was collected in four separate seasons. During the first ICECAP2 season (2015/16), a survey acquiring exploratory ‘fan-shaped’ radial profiles to maximize range and data return on each flight was completed across the...
