New publications on Sea Ice Elevation in the Western Weddell Sea, Antarctica
This work presents a method to retrieve sea ice elevations based on satellite synthetic aperture radar (SAR) imagery over old and rough sea ice in the Weddell Sea.
In the first part, we developed a radar theory relating electromagnetic scattering mechanisms to sea ice elevation over old and deformed rough ice.
In the second part, we generated a high-resolution map of sea ice elevation over a wide sector in the Western Weddell Sea. Numerous sea ice 3D features were derived from the sea ice elevation map, and these features provide oceanographic insights into sea ice formation processes in the Antarctic.
The work is supported by the Operational Icebridge and TanDEM-X Antarctic Scientific Campaign.
