Prydz Bay
Søstrene Islands () is a group of small islands and rocks that rise above the northern part of the Publications Ice Shelf at the head of Prydz Bay. They were discovered and charted in February 1935 by Captain Klarius Mikkelsen in the Norwegian whaling ship "Thorshavn", sent out by Lars Christensen. They gave the name "Søstrene" after the islands by that name lying in the entrance to the Oslofjord, Norway.
