Abstract
The drift of the large (length 160 km, area 5800 km2) A68A iceberg in the western part of the Weddell Sea is considered. Analysis was carried out on the basis of satellite images and field measurements in the region of the iceberg. The iceberg calved from the Larsen Glacier in July 2017 and slowly drifted northward. In February 2020, during cruise 79 of the R/V Akademik Mstislav Keldysh, hydrophysical observations were carried out near the iceberg. The presence of an iceberg in the western part of the Weddell Sea caused displacement of currents and fronts to the west in the space between the iceberg and the Antarctic Peninsula.
