The Balleny Islands ( English Balleny Islands ) are a group of uninhabited islands stretching over 190 km from northwest to southeast in the Somow Sea in the Southern Ocean around 2300 km south of New Zealand . The archipelago is about 300 kilometers from the Antarctic mainland ( Oatesland ) and is part of the Ross subsidiary area , the Antarctic territory claimed by New Zealand. However, since claims south of 60 degrees south latitude are not recognized under the Antarctic Treaty , the islands are not yet part of any state. The Balleny Islands are all completely in the Screaming Sixties .

geography

The 95% glaciated islands have a total area of ​​approximately 800 km² and are of volcanic origin. The archipelago consists of the three main islands Young Island , Buckle Island and Sturge Island as well as numerous, much smaller islets and rocks.

The Arctic Circle cuts the archipelago between Young and Buckle Island near Borradaile Island. The highest point of the archipelago, the still unclimbed Brown Peak with 1524 m height, is on Sturge Island. There are small emergency shelters on two islands: "Swan Base" on Borradaile and "Sabrina Refuge" on Sabrina Island.

history

Seal hunt on Young Island Beach (1894)

The archipelago was discovered in 1839 by whaling captains John Balleny with the schooner Eliza Scott and Thomas Freeman († 1839) with the cutter Sabrina . Thomas Freeman set foot on one of the islands for the first time on February 12, 1839 - this was also the first landing beyond the Arctic Circle.

In December 1894, the Balleny Archipelago was called by the Norwegian Bark Antarctic . The expedition under Captain Henryk Bull was commissioned to research the climatic and economic conditions of the Antarctic waters, especially for whale and seal hunting .

Since 1982 part of the archipelago (Sabrina Island, The Monolith and Chinstrap Island) has been under the protection of the Antarctic Treaty , since 2002 as specially protected area No. 104.

Wildlife

Seven species of birds have been shown to breed on the Balleny Islands. The silver petrel colonies on the northwest coast of Sturge Island are estimated to consist of 10,000 to 20,000 pairs, while the western cliffs are populated by approximately 10,000 pairs of snow petrels. 6000 pairs of the silver petrel breed on Row Island. The most common penguin species is the Adelie penguin . 3500 pairs breed on Sabrina Island alone. The chinstrap penguin, which is rarer on the Balleny Islands, is found in three colonies out of a total of 1350 pairs on Buckle Island. The other breeding birds are the Cape petrel , the Antarctic petrel and the spotted petrel .
