Riiser-Larsen Ice Shelf

Discovery and naming

Parts of the ice shelf were sighted by William Speirs Bruce in 1904, Ernest Shackleton in 1915, and Hjalmar Riiser-Larsen in 1930. Most of it was photographed from the air in 1951-52 by the Norwegian-British-Swedish Antarctic Expedition (NBSAE) and delineated from these photos. Additional delineation of the southern and landward margins of the feature was accomplished from aerial photos taken, by the USN's Operation Deep Freeze from 1967 to 1969. The feature was named by Norway for Captain Hjalmar Riiser-Larsen, who explored the area in the late 1920s and early 1930s.
