Herring, USN, photographic officer with Operation Windmill parties which obtained air and ground photos of the area in January 1948.
Bousquet Island, 0.6 kilometres (0.3 nmi) long, lies immediately east of Herring Island in the Windmill Islands. It was first mapped from air photos taken by USN Operation Highjump in 1946 and 1947. Named by C. R. Eklund, station scientific leader, for Utilities Man 2nd Class Edward A. Bousquet, USN, a Navy Support force member of the 1957 wintering party at Wilkes Station during the International Geophysical Year (IGY).
Bøving Island is a small Antarctic island in the south part of Newcomb Bay, lying 0.2 km (0.1 nmi) east of McMullin Island in the Windmill Islands.

Bøving, third officer on MV Thala Dan in 1965, who assisted in a hydrographic survey in the vicinity.
Fitzpatrick Rock is a low ice-capped rock lying 1 kilometre northwest of Kilby Island at the mouth of Newcomb Bay, in the Windmill Islands, Antarctica. It was first charted in February 1957 by a party from the USS Glacier. The name was suggested by Lt. Robert C. Newcomb, USN, navigator of the Glacier, for Boatswain's Mate 2nd Class John Fitzpatrick, USN, member of the survey party.
Kilby Island is a rocky Antarctic island, 0.37 kilometres (0.2 nmi) long, lying northeast of McMullin Island in the entrance of Newcomb Bay, in the Windmill Islands. It was first mapped from air photos taken by USN Operation Highjump and Operation Windmill in 1947 and 1948. It was named by the US-ACAN for Arthur L. Kilby, who served as photographer with both operations.
The Sikorski Glacier is a small glacier in the north-eastern part of the Noville Peninsula, Thurston Island, Ellsworth Land, Antarctica. It flows north-east to the Bellingshausen Sea between Mount Palmer and Mount Feury. It was first roughly delineated from aerial photos taken by the USN's Operation Highjump in 1946–47. It was named by the Advisory Committee on Antarctic Names (US-ACAN) for Stephen Sikorski, electronics technician on USS Glacier, who assisted in setting up an automatic weather station on Thurston Island during the USN's Bellingshausen Sea Expedition in February 1960.

It was first charted by the Discovery Expedition under Robert Falcon Scott, 1901–1904, then named by the Advisory Committee on Antarctic Names (US-ACAN) in 1964 for Donald E. Wohlschlag, professor of biology at Stanford University, who outfitted the biology laboratories on the USNS Eltanin and at McMurdo Station.
Coulter Glacier is a steeply inclined glacier, 5 nautical miles (9 km) long, flowing south from the Havre Mountains, northern Alexander Island, into Kolokita Cove in Lazarev Bay, Antarctica.
