Measurements of ice thickness were carried out by a ship-borne electromagnetic induction instrument mounted on the R/V Xuelong during the Second Chinese National Arctic Research Expedition (CHINARE-2003) in summer 2003 in the Chukchi Sea. A 1-D multi-layer model, consisting of three layers of snow, ice and seawater, was used to calculate the total thickness of snow and sea ice. The time series of total thickness from 24 August to 7 September 2003 indicates that deformed and second-/multi-year ice floes appear frequently in very close pack ice farther from the ice edge, while thinner ice floes less than 1 m are frequently found in open pack ice. The probability density function of total thickness shows that a major peak appears at around 1.5 m thickness in very close pack ice, presumably corresponding to second-year or deformed ice. Also shown is a peak at around 0.3 m thickness, corresponding to typical level ice in open pack ice.
