Skua Island (65°15′S 64°16′W / 65.250°S 64.267°W) is a roughly triangular island 0.7 nautical miles (1.3 km; 0.81 mi) long, lying between Black Island to the southwest and Winter Island and Galindez Island to the north and northeast, in the Argentine Islands, Wilhelm Archipelago.[1]
Location
[edit]
The Argentine Islands are off the Graham Coast of the Antarctic Peninsula. They are south of the French Passage, west of Mount Shackleton on the mainland, north of the Berthelot Islands and Grandidier Channel and east of the Betbeder Islands.[2]
Sailing directions
[edit]The US Defense Mapping Agency's Sailing Directions for Antarctica (1976) describes Skua Island and its surroundings as follows:
Cornice Channel, which separates Galindez Island and Skua Island, is narrow and shallow at its northern entrance; it has a depth of 4 feet in it. The channel between Galindez Island and Skua Island, which is known as Skua Creek (Skua Inlet), has depths that decrease from 11 fathoms at the northwestern entrance to 8 feet at the south-eastern extremity. The southeastern end of the channel is obstructed by foul ground. The northwestern entrance to the channel is narrowed by a bank, which extends from its northeastern side, and on which there is a rock with a depth of 6 feet over it. In 1947, the M.V. Trepassey entered this channel from northwestward and anchored otf the southeastern oorner of winter Island, close to the meteorological station. The fast Ice. In Skua Creek, does not always break ont each summer.[3]
A number of islets and above-water rocks lie within 200 yards of the western aide of Skua Island and shoals have been observed from the air, to extend about 400 yards southward from the southern side of the same island. The northwestern part of the Argentine Islands contain three groups of islands. The northern group is named Horseshoe Islands [Forge Islands], the central, Three Little Pigs, and the southern, Shelter Islands...[4]
The southwesternmost group of the Argentine Islands consists of two principal islands, of which the southeastern is named Black Island and the northwestern is named Leopard Island, and a number of islets and above-water and sunken rocks. Black Island Channel, which passes between Skua Island and Black Island, is about 200 yards wide, deep and dear of dangers in the fairway, but Runciman Rock, is marked by breakers, lies in the middle of the southern apprnech to the channel, about 200 yards eastward of Black Island, and shoals extend southward from Skua Island and about 200 yards southeastward from Finger Point, its southwestern extremity. A 7-foot depth Use about 600 yards eastward of Runciman Rock. The John Biscoe reported, in June 1950, that Meek Channel, as an anchorage and refuge, is preferable to Black Island Channel; and that throughout the two previous seasons Black Island Channel had been blocked by icebergs. Meek Channel Is also blocked at times by icebergs.[4]
Between Winter Island and Skua Island, on the southeast, and Three Little Pigs and Shelter Islands, on the northwest, is an area about half a mile long from east to west and about 400 yards wide, with depths of 8 to 19 fathoms. The channel leading to this area from Black Island Channel and peening between Skua Island and Shelter Island is deep and clear of dangers in the fairway. [4]
