Catodon Rocks ( 63°30′S60°0′W / 63.500°S 60.000°W / -63.500; -60.000 Coordinates: 63°30′S60°0′W / 63.500°S 60.000°W / -63.500; -60.000 ) are a small group of rocks just northeast of Ohlin Island, in the Palmer Archipelago. They were photographed by the Falkland Islands and Dependencies Aerial Survey Expedition in 1955–57 and mapped from these photos. They were named by the UK Antarctic Place-Names Committee in 1960 after the sperm whale, Physeter catodon.

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.

Ohlin Island island

Ohlin Island or Bailys Island is an island lying 11 kilometres (6 nmi) west of the north end of Tower Island in the Palmer Archipelago. Ohlin Island was discovered by the Swedish Antarctic Expedition (1901–1904) and named by Otto Nordenskiöld for Axel Ohlin, zoologist with the expedition.

Palmer Archipelago Group of islands off the northwestern coast of the Antarctic Peninsula

Palmer Archipelago, also known as Antarctic Archipelago, Archipiélago Palmer, Antarktiske Arkipel or Palmer Inseln, is a group of islands off the northwestern coast of the Antarctic Peninsula. It extends from Tower Island in the north to Anvers Island in the south. It is separated by the Gerlache and Bismarck straits from the Antarctic Peninsula and Wilhelm Archipelago, respectively.

South Orkney Islands A group of islands in the Southern Ocean north-east of the Antarctic Peninsula

The South Orkney Islands are a group of islands in the Southern Ocean, about 604 kilometres (375 mi) north-east of the tip of the Antarctic Peninsula and 844 kilometres (524 mi) south-west of South Georgia Island. They have a total area of about 620 square kilometres (240 sq mi). The islands are claimed both by Britain, and by Argentina as part of Argentine Antarctica. Under the 1959 Antarctic Treaty, sovereignty claims are held in abeyance.

Tabarin Peninsula

Tabarin Peninsula is a peninsula 15 nautical miles (28 km) long and 5 to 12 nautical miles (22 km) wide, lying south of the trough between Hope Bay and Duse Bay and forming the east extremity of Trinity Peninsula in the Antarctic Peninsula. It was discovered and charted by the Swedish Antarctic Expedition, 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.

The Governor Islands in the South Atlantic are a group of islands and rocks 0.5 nautical miles (1 km) north of Penguin Point, the northwestern extremity of Coronation Island, in the South Orkney Islands. They were discovered by Captain George Powell and Captain Nathaniel Palmer during their joint cruise in December 1821. The name appears on a chart based upon a running survey of the South Orkney Islands in 1912–13 by Petter Sorlle, a Norwegian whaling captain.

The Boyer Rocks are a small group of rocks in the northeast corner of Bone Bay, 3 nautical miles (6 km) southwest of Cape Roquemaurel, Trinity Peninsula. The rocks were mapped from surveys by the Falkland Islands Dependencies Survey (1960–61), and named by the UK Antarctic Place-Names Committee for Joseph Boyer, a French naval officer on the Astrolabe during her Antarctic voyage (1837–40).

Oluf Rocks is a small group of rocks lying 3.5 nautical miles (6 km) east of Cape Neumayer, Trinity Island, in the Palmer Archipelago. Photographed by the Falkland Islands and Dependencies Aerial Survey Expedition (FIDASE) in 1955-57 and mapped from these photos by the Falkland Islands Dependencies Survey (FIDS). Named by the United Kingdom Antarctic Place-Names Committee (UK-APC) in 1960 after the Danish freighter Oluf Sven which transported the FIDASE to Deception Island in 1955 and 1956, and was used during the two summer seasons as a mobile base for operations by ground survey parties.

West Melchior Islands is a group of small ice-covered islands and rocks which lie west of The Sound in the Melchior Islands, Palmer Archipelago. The islands east of The Sound are called East Melchior Islands. The name was probably given by DI personnel who roughly surveyed these islands in 1927. The islands were surveyed by Argentine expeditions in 1942, 1943 and 1948.

Physeter Rocks is a small group of rocks lying west of Ohlin Island, Palmer Archipelago, Antarctica. The rocks were photographed by Falkland Islands and Dependencies Aerial Survey Expedition (FIDASE), 1956–57, and mapped from these photos. They are named by the United Kingdom Antarctic Place-Names Committee (UK-APC) in 1960 after the sperm whale, Physeter catodon.

The Eden Rocks are two rocks lying 1.5 km off the east coast of Dundee Island, at the northern end of the Antarctic Peninsula. A small island was reported there on 30 December 1842 by Captain James Clark Ross of the Royal Navy, who named it "Eden Island" for Captain Charles Eden. Following a survey by the Falkland Islands Dependencies Survey in 1953, it was reported that the feature consists of two rocky islets rising to about 90 m in height and lying close together.

The Français Rocks are a group of fringing rocks lying off the northeast coast of D'Urville Island, in the Joinville Island group. The name "Pointe des Français" was given by Captain Jules Dumont d'Urville, of the French Antarctic Expedition, 1837–40, to the northeast point of the island which at that time was believed to be continuous with Joinville Island. Surveys by the Falkland Islands Dependencies Survey (1952–54) and aerial photographs by the Falkland Islands and Dependencies Aerial Survey Expedition (1956–57) have not revealed a definable point hereabout. For the sake of historical continuity in the area, the UK Antarctic Place-Names Committee (1978) applied the name Français Rocks to these fringing rocks.

Goudier Island is a small island with an appearance of bare, polished rock, lying 0.05 nautical miles (0.1 km) north of Jougla Point in the harbor of Port Lockroy, Wiencke Island, in the Palmer Archipelago. It was discovered by the French Antarctic Expedition, 1903–05, under Jean-Baptiste Charcot, and named after E. Goudier, chief engineer of the expedition ship Français.

The Minerva Rocks are a small group of rocks lying off Chionis Island near Trinity Island, in the Palmer Archipelago, Antarctica. They were so named by whalers because the Minerva, one of the whale catchers of the British factory ship Pythia, went aground on these rocks in March 1922. The catcher was abandoned and, because of the heavy swell, became a total wreck.

The Hydrodist Rocks are four rocks, one of which dries at low tide and two are submerged, lying 4 nautical miles (7 km) west of Trinity Island in the Palmer Archipelago, Antarctica. These rocks were fixed in January 1964 by HMS Protector (A146) by means of a helicopter-borne hydrodist.

Sinker Rock is a rock off the north tip of Goudier Island, near the center of the harbor of Port Lockroy, in the Palmer Archipelago. Rocks were charted in this position by the French Antarctic Expedition, 1903–05, under Charcot. So named by the Falkland Islands Dependencies Survey (FIDS) in 1944 because a sinker was laid near this rock for a boat mooring.

Ryge Rocks is a group of rocks lying east of Oluf Rocks, in the Palmer Archipelago. Photographed by the Falkland Islands and Dependencies Aerial Survey Expedition (FIDASE) in 1955-57 and mapped from these photos by the Falkland Islands Dependencies Survey (FIDS). Named by the United Kingdom Antarctic Place-Names Committee (UK-APC) in 1960 for J.C. Ryge, Danish master of the freighter Oluf Sven, chartered by the FIDASE, 1955-57.

The Kendall Rocks are a group of pillar-shaped rocks, lying 3 nautical miles (6 km) north of Tower Island in the Palmer Archipelago, Antarctica. The name "Kendall Group" appears northwest of this position on a chart based upon work by a British expedition under Commander Henry Foster, Royal Navy, 1828–31, but it was later found that no islands exist there. The name Kendall Rocks has subsequently been applied to these pillar-shaped rocks discovered in 1838 by a French expedition under Captain Jules Dumont d'Urville. They are named for Lieutenant E.N. Kendall of Foster's expedition ship, the Chanticleer.
