Clark Peninsula

Clark Peninsula is a rocky peninsula, about 3 km (2 mi) long and wide, lying 5 km (3 mi) north-east of Australia's Casey Station at the north side of Newcomb Bay on the Budd Coast of Wilkes Land in Antarctica.

The peninsula was first mapped from aerial photographs taken by the US Navy's Operation Highjump in February 1947 and thought to be an island connected by a steep snow ramp to the continental ice overlying Budd Coast.

This party was led by Scientific Station Leader Carl R. Eklund, who conducted many ground surveys and named many of the peninsula's features.

Unless otherwise noted, all of the following features were first mapped from air photos taken by Operation Highjump in 1946–1947, and named by Carl Eklund following ground surveys in 1957, typically for members of the Wilkes Station party.

[11] Gibney Reef is exposed off the shore 0.5 nautical miles (0.9 km) to the west of the peninsula.

[12] The 9.4 km2 peninsula is protected under the Antarctic Treaty System as Antarctic Specially Protected Area (ASPA) No.136 because of the long-term and ongoing research programs and monitoring studies carried out on its plant communities and Adélie penguin breeding colonies.

[13] The site has also been designated an Important Bird Area (IBA) by BirdLife International because of its large numbers of breeding seabirds.
