Prince Gustav Channel

The Prince Gustav Channel (63°50′S 58°15′W / 63.833°S 58.250°W / -63.833; -58.250 (Prince Gustav Channel)) is a strait about 80 nautical miles (150 km; 92 mi) long and from 4 to 15 nautical miles (7.4 to 27.8 km; 4.6 to 17.3 mi) wide, separating James Ross Island and Vega Island from the Trinity Peninsula, Antarctica.

It separates the James Ross Island group to the east from the Trinity Peninsula and Detroit Plateau to the west.

[1] On 27 February 1995, the British Antarctic Survey (BAS) reported that the ice shelf formerly blocking the channel had disintegrated.

[citation needed] Carbon dating of organic material found in the sediment layers suggested that for a period between 2,000 and 5,000 years ago, much of the channel was seasonally open water.

Prince Gustav Ice Shelf retreated in the mid-Holocene period 5000 to 2000 years before present, [this] "corresponds to regional climate warming deduced from other paleoenvironmental records.

With the return of colder conditions about 1900 years ago, the Prince Gustav Ice Shelf reformed until its recent retreat and collapse.

Named by the UK Antarctic Place-Names Committee (UK-APC) for Bramah J. Diplock, British engineer who made considerable advances in the design of chain-track tractors (1885-1913).

Glacier about 10 nautical miles (19 km; 12 mi) long, flowing east-southeast from the Detroit Plateau, Graham Land, to Prince Gustav Channel close north of Alectoria Island.

Surveyed by the FIDS, and so named because the glacier was sighted in the week following the surrender of Japan in World War II, in August 1945.

It lies in Prince Gustav Channel, about 0.5 nautical miles (0.93 km; 0.58 mi) off the terminus of Aitkenhead Glacier.

Circular, flat-topped island, 1 nautical mile (1.9 km; 1.2 mi) in diameter and 495 metres (1,624 ft) high, with reddish cliffs of volcanic rock, lying 3.5 nautical miles (6.5 km; 4.0 mi) northwest of Cape Lachman, James Ross Island, in Prince Gustav Channel.

A rock pillar rising to 495 metres (1,624 ft) high on Red Island in Prince Gustav Channel.
