Late spring 2018 land-fast sea ice and sub-ice platelet layer thicknesses from electromagnetic induction soundings on transect TNB-2021_NS-1_EM in Gerlache Inlet, Terra Nova Bay, Antarctica
Ground-based electromagnetic induction (EM) measurements of land-fast sea ice and sub-ice platelet layer thickness distributions were carried out on land-fast sea ice in Gerlache Inlet, Terra Nova Bay, Antarctica in late spring (November 3-7) of 2021. EM transects were carried out across Gerlache In...
