Adams Fjord

Last updated March 06, 2019

Adams Fjord, also variously known as Bukhta Semerka, Bukhta Semyorka or Seven Bay, is a fjord about 13 miles (21 km) long in the northeast part of Amundsen Bay, just south of Mount Riiser-Larsen. Photographed and mapped from ANARE (Australian National Antarctic Research Expeditions) aircraft during 1956. An ANARE party led by Phillip Law entered the fjord by motor launch from the Thala Dan on 14 February 1958 and made a landing at the foot of Mount Riiser-Larsen. Named by ANCA for Ian L. Adams, Officer-in-Charge at Mawson Station in 1958.

Geologically, a fjord or fiord is a long, narrow inlet with steep sides or cliffs, created by a glacier. There are many fjords on the coasts of Alaska, Antarctica, British Columbia, Chile, Greenland, the Faroe Islands, Iceland, Kamchatka, the Kerguelen Islands, New Zealand, Norway, Novaya Zemlya, Labrador, Nunavut, Newfoundland, Quebec, Scotland, South Georgia Island, and Washington state. Norway's coastline is estimated at 29,000 kilometres (18,000 mi) with nearly 1,200 fjords, but only 2,500 kilometres (1,600 mi) when fjords are excluded.

Amundsen Bay, also known as Ice Bay, is a long embayment 39 kilometres (24 mi) wide, close west of the Tula Mountains in Enderby Land, Antarctica. The bay was seen as a large pack-filled recession in the coastline by Sir Douglas Mawson on January 14, 1930. Seen by Captain Hjalmar Riiser-Larsen in charge of a Norwegian expedition during an airplane flight on January 15 and subsequently mapped nearer its true position by the Norwegians. The bay was mapped in detail by an Australian National Antarctic Research Expeditions party landed by aircraft in 1956 and another landed by launch from Thala Dan in February 1958. It was named by Mawson after Roald Amundsen, the Norwegian explorer who was first to reach the South Pole.

Mount Riiser-Larsen is a prominent mountain, 870 m, standing at the northwest end of the Tula Mountains on the east side of Amundsen Bay. It was named by the British Australian New Zealand Antarctic Research Expedition (BANZARE) under Mawson in January 1930 for Captain Hjalmar Riiser-Larsen, the leader of a Norwegian expedition in the Norvegia which also explored the area in that season.

United States Geological Survey scientific agency of the United States government

The United States Geological Survey is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization has four major science disciplines, concerning biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility.

The Geographic Names Information System (GNIS) is a database that contains name and locative information about more than two million physical and cultural features located throughout the United States of America and its territories. It is a type of gazetteer. GNIS was developed by the United States Geological Survey in cooperation with the United States Board on Geographic Names (BGN) to promote the standardization of feature names.

Geographic coordinate system Coordinate system

A geographic coordinate system is a coordinate system that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are often chosen such that one of the numbers represents a vertical position and two or three of the numbers represent a horizontal position; alternatively, a geographic position may be expressed in a combined three-dimensional Cartesian vector. A common choice of coordinates is latitude, longitude and elevation. To specify a location on a plane requires a map projection.

Mount Menzies is the culminating peak on the large massif between Mount Mather and Mount Bayliss, standing on the south side of Fisher Glacier, Antarctica. It was sighted by Flying Officer J. Seaton from an ANARE Beaver aircraft in 1956, and mapped by an ANARE southern seismic party under K.B. Mather in 1957–58. Mount Menzies was named by ANCA after the Rt. Hon. Robert Menzies, Prime Minister of Australia, 1939–41 and 1949–66.

The Prince Charles Mountains are a major group of mountains in Mac. Robertson Land in Antarctica, including the Athos Range, the Porthos Range, and the Aramis Range. The highest peak is Mount Menzies. Other prominent peaks are Mount Izabelle and Mount Stinear. These mountains together with other scattered peaks form an arc about 260 miles long, extending from the vicinity of Mount Starlight in the north to Goodspeed Nunataks in the south.

Cape Ann is a cape on the coast of East Antarctica, surmounted by Mount Biscoe rising to a peak of 700 metres.

The Tula Mountains are a group of extensive mountains lying immediately eastward of Amundsen Bay in Enderby Land, Antarctica. They were discovered on January 14, 1930 by the British Australian New Zealand Antarctic Research Expedition (BANZARE) under Mawson and named "Tula Range" by him after John Biscoe's brig, the Tula, from which Biscoe discovered Enderby Land in 1831. The term "mountains" was recommended for the group following an ANARE sledge survey in 1958 by G.A. Knuckey.

The Scott Mountains are a large number of isolated peaks lying south of Amundsen Bay in Enderby Land of East Antarctica, Antarctica. Discovered on 13 January 1930 by the British Australian New Zealand Antarctic Research Expedition (BANZARE) under Sir Douglas Mawson. He named the feature Scott Range after Captain Robert Falcon Scott, Royal Navy. The term mountains is considered more appropriate because of the isolation of its individual features.

Athos Range is the northernmost range in the Prince Charles Mountains of Mac. Robertson Land, Antarctica. The range consists of a large number of individual mountains and nunataks that trend east-west for 40 miles (60 km) along the north side of Scylla Glacier.
