Princess Martha Coast

Princess Martha Coast. It is a sector of Coats Land along the Weddell Sea in East Antarctica. Named for Princess Märtha of Sweden, the coast is defined by major ice shelves and nunataks. It has been a significant area for polar exploration and modern scientific research.

Geography

The coastline is dominated by the extensive Fimbul Ice Shelf and the Veststraumen Glacier. Key geographical features include the prominent Wohlthat Mountains and the Mühlig-Hofmann Mountains, which form part of the larger Orvin Mountains range. Notable landmarks are Jutulstraumen Glacier, one of Antarctica's largest ice streams, and the Drygalski Mountains. The region borders the Princess Astrid Coast to the west and the Princess Ragnhild Coast to the east, with its interior reaching toward the polar plateau near the South Pole.

History

The area was first sighted by the German Antarctic Expedition led by Wilhelm Filchner aboard the ship ''Deutschland'' in 1912. It was later mapped in detail by the Third German Antarctic Expedition under Alfred Ritscher, which named it for the Swedish princess. The Norwegian–British–Swedish Antarctic Expedition conducted extensive scientific work here in the late 1940s. Subsequent major expeditions include those by the Soviet Antarctic Expedition and the United States Antarctic Program, which established permanent research stations. The region is governed under the terms of the Antarctic Treaty System.

Climate

The climate is characterized as a severe polar climate, with temperatures rarely rising above freezing. It experiences the extreme polar night during the Antarctic winter and the midnight sun in the summer months. The coast is influenced by cold air drainage from the Antarctic ice sheet and frequent katabatic winds. Weather patterns are also affected by the proximity to the Weddell Sea and the formation of sea ice.

Flora and fauna

Terrestrial life is extremely limited, consisting primarily of lichens, mosses, and algae found on exposed nunataks. The coastal and marine ecosystems are more vibrant, supporting populations of Adélie penguin, Antarctic petrel, and snow petrel. The Weddell Sea waters are important for Antarctic krill, which sustains Weddell seal, leopard seal, and minke whale. The Southern Ocean here falls under the purview of the Commission for the Conservation of Antarctic Marine Living Resources.

Research stations

The primary year-round facility is Neumayer-Station III, operated by the Alfred Wegener Institute for Germany. Another significant base is the SANAE IV station, maintained by the South African National Antarctic Programme. Seasonal field camps are often established by the Norwegian Polar Institute and other national programs. These stations conduct research in disciplines like glaciology, atmospheric sciences, and marine biology, contributing to global projects such as the International Polar Year.
