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

Published: 2012-09-03

In 1985, the Nella Dan was trapped in sea ice for several weeks while undertaking a marine science voyage (Voyage 1, (85/86) ADBEX III). 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 in order to get rotations with redundancy. Observations were completed several times a day. The physical logs are archived at the Australian Antarctic Division.
