Late spring 2018 land-fast sea ice and sub-ice platelet layer thicknesses from electromagnetic induction soundings along transect West-East-EM-Transect_20181107 in McMurdo Sound, Antarctica
Ground-based electromagnetic induction (EM) time-series measurements of land-fast sea ice and sub-ice platelet layer thickness distributions were carried out on land-fast sea ice in McMurdo Sound, Antarctica late spring (November 01-19) of 2018. Repeated west to east EM transects were carried out ac...
