Spring 2018 time-series measurement of land-fast sea ice and sub-ice platelet layer thicknesses from electromagnetic induction soundings in McMurdo Sound, Antarctica
PANGAEA
Brett, Gemma Marie; Leonard, Gregory H; Rack, Wolfgang; Irvin, Anne; Haas, Christian; Langhorne, Patricia J; Smith, Inga J — 2024 Ground-based electromagnetic induction (EM) time-series measurements of land-fast sea ice and sub-ice platelet layer thicknesses were carried out on land-fast sea ice in McMurdo Sound, Antarctica in winter (August 8 to 26 October) and late spring (November 4-18) of 2018. The EM data were acquired using a frequency-domain Geonics Ltd EM31-MK2 instrument mounted on the sea ice surface in winter and a sledge in late spring. 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 (i.e., Apparent Conductivity (AppCond) and Inphase (Inph)) using the forward modelling and inversion methods of Irvin (2018). Temporal variability in EM measured thicknesses detected the seasonal growth of land-fast sea ice and sub-ice platelet layer in winter, and shorter timescale variability related to strong offshore wind events in winter and the tides in late spring (Brett et al., 2024). https://creativecommons.org/licenses/by/4.0/legalcode

Brett, Gemma Marie; Leonard, Gregory H; Rack, Wolfgang; Irvin, Anne; Haas, Christian; Langhorne, Patricia J — 2024 Ground-based electromagnetic induction (EM) measurements of land-fast sea ice and sub-ice platelet layer (SIPL) thickness distributions were carried out in McMurdo Sound, Antarctica in late spring (November 1-19) of 2018. Repeated west to east EM transects were carried out across McMurdo Sound along latitude 77.767°S. 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 forward modelling and inversion methods of Irvin (2018). Variability in EM thicknesses detected significant growth of sub-ice platelet layer over the 18-day survey period (Brett et al., 2024). https://creativecommons.org/licenses/by/4.0/legalcode
