Sea Ice Mass Balance in the Antarctic - Shipboard Electro-Magnetic induction (EMI) Ice Thickness
Entry ID: SIMBA_Shipboard_EMI_Ice_Thickness

[ Update this Record ]

Summary
Abstract: EMI (electromagnetic induction) records of ice thickness, utilized a Geonics EM-31 induction meter, were conducted with the meter suspended from the ship’s starboard A-frame, at heights varying from 2.5 to 4.0 meters. Conductance data (in millisiemens/meter) were acquired at 2 second intervals. Heights to the snow/ice surface were measured with a sonic ranger attached to the frame housing the ... View entire text

Purpose: Ice thickness values in continuous tracks in the Antarctic sea ice zone obtained here are important for determining the ice thickness variations over distances of tens of kilometers. Measurements made on ice floes by drilling provide important calibration points but the areal distribution of ice thickness can only be determined by these shipborne methods, and these are commensurate with the scale of satellite remote sensing imagery and the grid resolution of sea ice models.
