King Peninsula

King Peninsula (-73.2°N, -101°W) is an ice-covered peninsula, 100 nmi long and 20 nmi wide, lying south of Thurston Island and forming the south side of Peacock Sound, Antarctica. It projects from the continental ice sheet and trends west between the Abbot Ice Shelf and Cosgrove Ice Shelf to terminate at the Amundsen Sea.

Location
The north shore of the King Peninsula is the western end of the Eights Coast, while the west and southern shore is in the Walgreen Coast. Peacock Sound is to the north, completely filled by the western part of the Abbot Ice Shelf. The Amundsen Sea is to the west. Ferrerro Bay and the Cosgrove Ice Shelf are to the south. Burke Island is in the sea to the west. The Waite Islands are off Cape Waite, the northwest extremity of the peninsula. Marelli Glacier drains northeast from the peninsula into the Abbot Ice Shelf.

Mapping and name
The King Peninsula was photographed from the air by United States Navy Operation Highjump, 1946–47. It was plotted from these photos as a long island, or possible peninsula. Photos taken by the United States Navy in 1966 show it is a peninsula. King Peninsula was named by the United States Advisory Committee on Antarctic Names (US-ACAN) for Fleet Admiral Ernest J. King, United States Navy, Chief of Naval Operations from 1942 to 1945, who approved the preliminary work for Operation Highjump (OpHjp).

Glaciers
Glaciers flowing into Peacock Sound are, from northwest to southeast,

Stapleton Glacier
-72.93333°N, -102.5°W Glacier about 6 nmi long flowing east from King Peninsula just north of Morelli Glacier. Named by US-ACAN after Jo Anne Stapleton, United States Geological Survey (USGS), Reston, Virginia, geographer and map specialist, participated in Antarctic map production from the 1980s to the present, part of the United States Geological Survey (USGS) team that compiled the 1:5,000,000-scale Advanced Very High Resolution Radiometer maps of Antarctica and the 1: 250,000-scale Landsat TM image maps of the Siple Coast area.

Morelli Glacier
-72.98333°N, -102.55°W. A glacier in the west part of King Peninsula, 18 nmi southeast of Cape Waite, draining northeast to Abbot Ice Shelf in Peacock Sound. Mapped by USGS from surveys and United States Navy air photos, 1960-66. Named by US-ACAN for Panfilo S. Morelli, glaciologist at Byrd Station, 1961-62.

Rignot Glacier
-73.1°N, -102°W Glacier about 4 nmi long draining north from the King Peninsula into Abbot Ice Shelf. Named by US-ACAN after Eric J. Rignot, Jet Propulsion Laboratory, California Institute of Technology, geophysicist; uses field and remotely sensed data to study Antarctic glacier mechanics from the 1990s to the present.

Rosanova Glacier
-73.25°N, -97.91667°W Glacier about 8 nmi long flowing north from King Peninsula into the Abbot Ice Shelf. Named by US-ACAN after Christine E. Rosanova, United States Geological Survey (USGS), Flagstaff, AZ; specialist in the use of satellite imagery for geological and glaciological studies from the early 1990s to 2002; a pioneer in the use of imagery for glacier velocity measurements.

Features
Features surrounding the peninsula include, clockwise from the south,

Cosgrove Ice Shelf

Cosgrove, United States Navy Reserve, assistant communications officer on the staff of the Commander, United States Navy Support Force, Antarctica, during United States Navy OpDFrz, 1967 and 1968.

Ferrero Bay
-73.46667°N, -102.5°W. A body of water about 15 nmi wide, lying immediately west of Cosgrove Ice Shelf and occupying the outer (west) part of the embayment between King and Canisteo Peninsulas. Mapped from air photos taken by United States Navy OpHjp in December 1946. Named by US-ACAN for Lieutenant Commander H.H. Ferrero, communications officer on the staff of the Commander, United States Navy Support Force, Antarctica, 1966-68.

Early Islands
