Schmidt Glacier (53°3′S 73°24′E / 53.050°S 73.400°E) is a glacier, 0.7 nautical miles (1.3 km) long, flowing west from Baudissin Glacier between Mount Drygalski and North West Cornice, on the west side of Heard Island.[5][6] To the north of Schmidt Glacier is Baudissin Glacier, whose terminus is located at the western side of Corinthian Bay, near Sealers Cove. Kildalkey Head is west of Schmidt Glacier. To the south of Schmidt Glacier is Vahsel Glacier, whose terminus is at South West Bay, between Erratic Point and Cape Gazert. Immediately south of Vahsel Glacier is Allison Glacier.
Discovery and naming
Schmidt Glacier was roughly charted in 1902 by the 1st German Antarctic Expedition under Erich von Drygalski. He named it for Dr. J. Schmidt of the Royal Prussian Ministry, who assisted in obtaining government support for the expedition.[5][6]
Retreat of Heard Island glaciers
Heard Island is a heavily glacierized volcanic island in the Southern Ocean. 80% of the island is covered in ice, with glaciers descending from 2400 meters to sea level.[1] Due to the steep topography of Heard Island, most of its glaciers are relatively thin (averaging only about 55 meters in depth).[2]
Retreat of glacier fronts across Heard Island is evident when comparing aerial photographs taken in December 1947 with those taken on a return visit in early 1980.[1] During the time period between 1947 and 1988, the area of Heard Island's glaciers decreased by 11%, from 288 km² (roughly 79% of the total area of Heard Island) to only 257 km².[2] A Spring 2000 visit to the island found that the Stephenson, Brown and Baudissin glaciers, among others, had retreated even further. [2] Retreat of Heard Island glaciers is most dramatic on the eastern section of the island, where the termini of former tidewater glaciers are now located inland.[1] Glaciers on the northern and western coasts have narrowed significantly, while the area of glaciers and ice caps on Laurens Peninsula have shrunk by 30% - 65%.[2][1] The retreat of Heard Island's glaciers is expected to continue for the forseeable future.[1]
Flora and fauna
To date, no flora or fauna have been observed within 1.0 degrees of Schmidt Glacier.[6]
