This study took place between September and November 1989 in the Weddell Sea, Antarctica. Several times each day throughout the cruise, we took notes on the ice conditions that the ship was passing through at that time. These notes included ice concentration, thickness, ice type, amount of ridging, number of icebergs in the area and other distinguishing characteristics. Photos of the area are included. During the cruise a Soviet ice scientist was stationed on the bridge 24 hours a day to compile detailed ice observation maps. These maps contain information for every mile of ice that was passed through during the cruise, including ice thickness, type and concentration; iceberg size, number and type; and the extent and size of leads. Copies of their maps are included. Every 30-60 miles during the cruise we would stop for an ice station where ice cores and water measurements were made. At each site Dr. Shilnikov compiled an ice map of the station, including wind direction and speed, air temperature, ice type, ice thickness and other characteristics of the area. Copies of these maps are included. Daily satellite photos of the area the ship was traversing are also provided. 收起
