McGrady Cove
McGrady Cove () is a cove at the head of Newcomb Bay in the Windmill Islands of Antarctica. It was first mapped from air photos taken by U.S. Navy Operation Highjump and Operation Windmill in 1947 and 1948, and was named by the Advisory Committee on Antarctic Names The Advisory Committee on Antarctic Names (ACAN or US-ACAN) is an advisory committee of the United States Board on Geographic Names responsible for recommending commemorative names for features in Antarctica.

Cove
A cove is a small type of bay or coastal inlet. Coves usually have narrow, restricted entrances, are often circular or oval, and are often situated within a larger bay. Small, narrow, sheltered bays, inlets, creeks, or recesses in a coast are often considered coves. Colloquially, the term can be used to describe a sheltered bay. Geomorphology describes coves as precipitously-walled and rounded cirque-like openings as in a valley extending into or down a mountainside, or in a hollow or nook of a cliff or steep mountainside. A cove can also refer to a corner, nook, or cranny, either in a river, road, or wall, especially where the wall meets the floor. A notable example is Lulworth Cove on the Jurassic Coast in Dorset, England. To its west, a second cove, Stair Hole, is forming. Formation Coves are formed by differential erosion Weathering is the deterioration of rocks, soils and minerals as well as wood and artificial materials through contact with water, atmospheric gase ...

Newcomb Bay
Newcomb Bay is a sheltered bay about 1 mile (1.6 km) in extent, between Clark Peninsula and Bailey Peninsula in the Windmill Islands area. First mapped from U.S. Navy Operation Highjump aerial photographs taken in February 1947. In February 1957, Willis L. Tressler, oceanographer, led a party from the USS Glacier (AGB-4) to survey the bay and record depth soundings. Name suggested by Tressler for Lieutenant Robert C. Newcomb, U.S. Navy, navigator of the Glacier and member of the survey party. On the northern side of Newcomb Bay, Wilkes Station was located, while the southern side is the location of Casey Station Casey Station, commonly called Casey, is one of three permanent stations and research outposts in Antarctica managed by the Australian Antarctic Division (AAD). Casey lies on the northern side of the Bailey Peninsula (Antarctica), Bailey Peninsu .... See also * Larsen Bank * Orton Reef References Bays of Wilkes Land {{WilkesLand-geo-stub ...

Windmill Islands
The Windmill Islands are an Antarctic group of rocky islands and rocks about wide, paralleling the coast of Wilkes Land for immediately north of Vanderford Glacier along the east side of Vincennes Bay. Kirkby Shoal is a small shoal area with depths of less than extending about westwards and SSW, about from the summit of Shirley Island, Windmill Islands, and NW of Stonehocker Point, Clark Peninsula. The Windmill Islands were mapped from aerial photographs taken by USN Operation Highjump, 1946–47. So named by the US-ACAN because personnel of Operation Windmill, 1947–48, landed on Holl Island at the southwest end of the group to establish ground control for USN Operation Highjump photographs. The term "Operation Windmill" is a popular expression which developed after the expedition disbanded and refers to the extensive use of helicopters made by this group. The official title of this expedition was the 'Second Antarctic Development Project', U.S. Navy Task Force 39, 1947†... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Operation Highjump
Operation HIGHJUMP, officially titled The United States Navy Antarctic Developments Program, 1946–1947, (also called Task Force 68), was a United States Navy (USN) operation to establish the Antarctic research base Little America IV. The operation was organized by Rear Admiral Richard E. Byrd, Jr., USN (Ret), Officer in Charge, Task Force 68, and led by Rear Admiral Ethan Erik Larson, USN, Commanding Officer, Task Force 68. Operation HIGHJUMP commenced 26 August 1946 and ended in late February 1947. Task Force 68 included 4,700 men, 13 ships, and 33 aircraft. HIGHJUMP's objectives, according to the U.S. Navy report of the operation, were: # Training personnel and testing equipment in frigid conditions; # Consolidating and extending the United States' sovereignty over the largest practicable area of the Antarctic continent (publicly denied as a goal before the expedition ended); # Determining the feasibility of establishing, maintaining, and utilizing bases in the Antarctic an ...

Operation Windmill
Operation Windmill (OpWml) was the United States Navy's Second Antarctica Developments Project, an exploration and training mission to Antarctica in 1947–1948. This operation was a follow-up to the First Antarctica Development Project known as Operation Highjump. The expedition was commanded by Commander Gerald L. Ketchum, USN, and the flagship of Task Force 39 was the icebreaker USS ''Burton Island''. Missions during Operation Windmill varied including supply activities, helicopter reconnaissance of ice flows, scientific surveys, underwater demolition surveys, and convoy exercises. Malcolm Davis collected live animals, such as penguins and leopard seals, for zoological studies. The icebreaker USS ''Edisto'' (AG-89) sailed on 1 November 1947 for the Panama Canal to rendezvous with the ''Burton Island'' for the expedition.U.S. NAVY SECOND ANTARCTICA DEVELOPMENTS PROJECT, OPERATION WINDMILL, 1947–1948. http://www.south-pole.com/windmill.htm See also *List of Antarctic e ...

Advisory Committee On Antarctic Names
The Advisory Committee on Antarctic Names (ACAN or US-ACAN) is an advisory committee of the United States Board on Geographic Names responsible for recommending commemorative names for features in Antarctica. History The committee was established in 1943 as the Special Committee on Antarctic Names (SCAN). It became the Advisory Committee on Antarctic Names in 1947. Fred G. Alberts was Secretary of the Committee from 1949 to 1980. By 1959, a structured nomenclature was reached, allowing for further exploration, structured mapping of the region and a unique naming system. A 1990 ACAN gazeeter of Antarctica listed 16,000 names. Description The United States does not recognise territorial boundaries within Antarctica, so ACAN assigns names to features anywhere within the continent, in consultation with other national nomenclature bodies where appropriate, as defined by the Antarctic Treaty System. The research and staff support for the ACAN is provided by the United States Geologi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
