Peterson Island

The island was first mapped from aerial photos taken by the USN's Operation Highjump and Operation Windmill in 1947 and 1948. It was named by the US-ACAN for Lt. Mendel L. Peterson, USN, supply officer with Operation Windmill which established astronomical control stations in the area in January 1948.

Benlein Point is the southernmost point of the island. It was named by the US-ACAN for Construction Man Franklin J. Benlein, USN, a member of the Wilkes Station party of 1958.

Mackemer Point is the north-westernmost point of the island. It was named by the US-ACAN for Aerographer's Mate Frederick W. Mackemer, USN, another member of the Wilkes Station party of 1958.

Knowles Passage separates Holl Island from Peterson Island. It was named by US-ACAN for Lt Lloyd C. Knowles, USN, engineer officer of the USS Burton Island, who took part in survey and photographic operations in January 1948.

A 397 ha site, comprising the whole island and its central inlet, has been designated an Important Bird Area (IBA) by BirdLife International because it supports a colony of some 30,000 Adélie penguins, based on 2011 satellite imagery. Other birds breeding on the island include a large colony of snow petrels, as well as Cape petrels, southern fulmars, south polar skuas and Wilson's storm petrels. Southern elephant seals haul out and breed on the island's northern and north-western slopes, the most southerly known breeding site for the species.^[1]
