Tracking Near-Ship Icebergs from Ship Observations in Pack Ice, 1985

In 1985, the Nella Dan was trapped in sea ice for several weeks while undertaking a marine science voyage. During the time it was trapped, iceberg drift was measured in the region, tracking the movement of several icebergs relative to the ship. Iceberg movements included mt biscoe angle, bearing, and ship position so can get rotations with redundancy. Observations were done several times a day. The physical logs are archived at the Australian Antarctic Division.
