Location

::figure[src="https://upload.wikimedia.org/wikipedia/commons/a/a9/Trinity_Peninsula.svg" caption="Trinity Peninsula on Antarctic Peninsula. Tabarin Peninsula east of the tip"] ::

Tabarin Peninsula lies in Graham Land and forms the east tip of Trinity Peninsula, which is itself the tip of the Antarctic Peninsula. The peninsula extends in a southeast direction from the tip of Trinity Peninsula. It is separated by Antarctic Sound from the Joinville Island group to the east. It is northwest of the Erebus and Terror Gulf, and northeast of James Ross Island. Argentina's Esperanza Base is at the northeast end of the peninsula, beside Uruguay's ECARE base, named for Ruperto Elichiribehety.

The Tabarin Peninsula extends southwards into the Weddell Sea for about 25 km. It is connected to the mainland by an isthmus about 12 km wide which lies between Hope Bay to the north and Duse Bay to the south. The average height of the peninsular is about 250 m and the highest point, at around 1000 m, is Mount Taylor which lies just north of the isthmus.

Discovery and name

The Tabarin Peninsula was discovered and charted by the Swedish Antarctic Expedition (SwedAE), 1901–1904, led by Otto Nordenskjöld and Carl Anton Larsen. It was mapped in 1946 by the Falkland Islands Dependencies Survey (FIDS) and named after Operation Tabarin, the naval code name for the FIDS from 1943 to 1945.

Geology

Recently, more of the ground surface of the peninsula has become exposed by the melting of ice, and its geological structure is becoming clearer. Near Trepassey Bay there is a 60 m bed of steeply-dipping quartz-rich sandstones and mudstones which are probably part of the Hope Bay Formation dating to the Permian-Triassic. Dioritic rocks in this area are probably part of the early Cretaceous Antarctic Peninsula batholith. Rocks exposed above Duse Bay are Mesozoic marine sediments dipping gently to the southeast, and consisting of 60% coarse-grained conglomerates, 30% mudstones and 10% sandstones.

Flora and fauna

The crumbling cliffs of Brown Bluff tower over Trepassey Bay, causing rock falls and scree slopes, and some wind-eroded boulders fall to the beach below. There are a few lichens on boulders at the top of the beach and some mosses grow higher up the slope, but no vascular plants grow here. Weddell seals often haul out on the beach and leopard seals hunt offshore. This is a breeding site for gentoo and Adélie penguins, Cape petrels, snow petrels, skuas and kelp gulls. Other birds that probably breed here include the southern giant petrel, the southern fulmar and Wilson's storm petrel.
