Jensen Ridge ( 60°41′S45°38′W / 60.683°S 45.633°W / -60.683; -45.633 Coordinates: 60°41′S45°38′W / 60.683°S 45.633°W / -60.683; -45.633 ) is a curving ridge running eastward from Foca Point toward Jane Col on Signy Island in the South Orkney Islands. It was named in 1991 by the UK Antarctic Place-Names Committee after Captain Gullik Jensen, of the whaling ship Strombus from Tønsberg, Norway, who made the last whaling expedition to Signy Island in 1935–36.

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.

Foca Point is a rocky point forming the south side of the entrance to Express Cove on the west side of Signy Island in the South Orkney Islands. It was surveyed in 1947 by the Falkland Islands Dependencies Survey, and was named by the UK Antarctic Place-Names Committee for the whale catcher Foca, belonging to the Compañía Argentina de Pesca, which visited the South Orkney Islands in December 1926.

Jane Col is a col to the west of Jane Peak at the head of Limestone Valley on Signy Island in the South Orkney Islands. It was named in association with Jane Peak by the UK Antarctic Place-Names Committee.

Laws Glacier

Laws Glacier is a confluent glacier system which flows into Marshall Bay on the south coast of Coronation Island, in the South Orkney Islands off Antarctica. It was surveyed in 1948–49 by the Falkland Islands Dependencies Survey (FIDS), and was named by the UK Antarctic Place-Names Committee for Richard M. Laws of the FIDS, leader and biologist at Signy Research Station in 1948 and 1949, and at South Georgia in 1951.

Williams Haven is a cove 0.2 nautical miles southwest of North Point, Signy Island, in the South Orkney Islands. There is a large sea cave in the cliff on the north side of the cove. Named by United Kingdom Antarctic Place-Names Committee (UK-APC) in 1990 after David D. Wynn-Williams, British Antarctic Survey (BAS) microbiologist from 1974, including two winters and six summer seasons on Signy Island.

Usnea Ridge is a ridge at an elevation of 100–160 m, extending north-northwest from Jane Peak to Spindrift Col in central Signy Island, South Orkney Islands. This ridge was an ecological study site for British Antarctic Survey (BAS) biologists. Named by the United Kingdom Antarctic Place-Names Committee (UK-APC) in 1991 after lichens of the genus Usnea, which form a main element of the plant life on the ridge.

Confusion Island is an island 0.2 nautical miles (0.4 km) long at the west side of the entrance to Clowes Bay, off the south side of Signy Island.

Port Jebsen is a cove immediately north of Jebsen Point on the west side of Signy Island, in the South Orkney Islands. It was charted in 191213 by Petter Sorlle, a Norwegian whaling captain. The cove is named in association with Jebsen Point.

Jane Peak is a conspicuous nunatak, 210 metres (700 ft) high, standing 0.5 nautical miles (1 km) west of the northern part of Borge Bay on Signy Island, in the South Orkney Islands. It was roughly surveyed in 1933 by Discovery Investigations personnel, and resurveyed in 1947 by the Falkland Islands Dependencies Survey. It was named in 1954 by the UK Antarctic Place-Names Committee for the brig Jane, James Weddell commanding, which visited the South Orkney Islands in 1822–23.

Fyr Channel is a channel 0.2 nautical miles (0.4 km) wide between the southwest end of Signy Island and Moe Island, in the South Orkney Islands. The name "Fyr Strait" appears on a manuscript chart drawn by Captain Petter Sorlle in 1912, and corrected by Hans Borge in 1913, but the generic term channel is approved because of the small size of this feature. The Corral Whaling Co. of Bergen, a subsidiary of Messrs. Christensen and Co., Corral, Chile, operated the steam whaler Fyr in the South Orkney Islands in 1912-13.

Strombus Ridge is a ridge curving eastward from Thulla Point toward Jane Col on Signy Island, South Orkney Islands. The feature is 0.3 nautical miles (0.6 km) south of Jensen Ridge. Named by the United Kingdom Antarctic Place-Names Committee (UK-APC) after the whaling ship Strombus, from Tonsberg, Norway, used on the last whaling expedition to Signy Island, 1935-36.

Deschampsia Point is a point on the northwest side of Signy Island, South Orkney Islands, 0.3 nautical miles (0.6 km) northeast of the Spindrift Rocks. It was descriptively named by the UK Antarctic Place-Names Committee in 1991, following British Antarctic Survey ecological research, after the Antarctic hair grass Deschampsia antarctica, which grows on the slopes near the point.

Flensing Islands

The Flensing Islands are a group of small islands lying 1 nautical mile (2 km) west of Foca Point on the west side of Signy Island, in the South Orkney Islands. The islands were named "Flenserne" on a chart of 1912–13 by Norwegian whaling captain Petter Sorlle. The name Flensing Islands, suggested by the earlier Norwegian name, was used by Discovery Investigations personnel on the Discovery II who surveyed the group in 1933. Flensing is the process of stripping skin and blubber from whales.

The Moss Braes are west-facing slopes (braes) situated west of Robin Peak on Signy Island, in the South Orkney Islands off Antarctica. They were named by the UK Antarctic Place-Names Committee in 1990 from the extensive moss banks on the dissected rocky slopes.

Lovegrove Point is the north entrance point to Express Cove on the west side of Signy Island, South Orkney Islands, Antarctica. It was named by the UK Antarctic Place-Names Committee after Ian W.

McLeod Glacier (South Orkney Islands) glacier on Signy Island in the South Orkney Islands

McLeod Glacier is a glacier 1 nautical mile (2 km) long, flowing in a southeasterly direction into Clowes Bay on the south side of Signy Island, in the South Orkney Islands off Antarctica.
