摘要
Ship-based sea ice observation data (concentrations, ice thickness, topography and overlying
snow cover) were collected from Middle Weddell Sea to Prydz Bay, Antarcticduringthe period of 4 to 17
Jan 2003. Antarctic ice chart of first week of Jan 2003 was derived from National Ice Center (NIC). The
compared analysis of sea ice concentrations and thickness distributions were conducted though in situ data
and NIC chart. Results from sea ice concentration-analysis indicated the presence of large-scale open
water between 2000 and 4100 km along transit route resulted from sea ice drifting. We describe the exist-
ence of mostly smooth first-year sea ice in study region ranged between 30 and 120 cm. We also display
the derived overlying snow coverage. Our results reveal the strong correspondence between ship-based
observations and remotely sensed ice charts whatever in ice concentrations and ice thickness distributions.
