Abstract:
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 Inlet in north to south and east to west directions. The EM data were acquired using a frequency-domain Geonics Ltd EM31-MK2 instrument mounted on a sledge and towed by skidoo. The thicknesses of consolidated ice (sea ice plus the snow layer) and the SPL were simultaneously retrieved from the EM31 measured response using the forward modelling and inversion methods of Irvin (2018).

Ground-based electromagnetic induction (EM) measurements of land-fast sea ice and sub-ice platelet layer (SIPL) 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 Inlet in north to south and east to west directions. The EM data was acquired using a frequency-domain Geonics Ltd EM31-MK2 instrument mounted on a sledge and towed by skidoo. The thicknesses of consolidated ice (sea ice plus the snow layer) and the sub-ice platelet layer were simultaneously retrieved from the EM31 measured response using the forward modelling and inversion methods of Irvin (2018) and are presented here geolocated in latitude and longitude (decimal degrees).
