Scree Peak
Scree Peak () is a conspicuous, flat-topped peak with talus-covered slopes, 560 m, standing at the northeast end of Eagle Island in Prince Gustav Channel The Prince Gustav Channel was named in 1903 after Crown Prince Gustav of Sweden (later King Gustav V) by Otto Nordenskiöld of the Swedish Antarctic Expedition. The channel is bounded on the west by the Antarctic Peninsula and on the east by Ja ..., off the south coast of Trinity Peninsula. Discovered by the Falkland Islands Dependencies Survey (FIDS) and so named following their 1945 survey. The name is descriptive of the slopes of the peak.

Summit (topography)
A summit is a point on a surface that is higher in elevation than all points immediately adjacent to it. The topographic terms acme, apex, peak (mountain peak), and zenith are synonymous. The term (mountain top) is generally used only for a mountain peak that is located at some distance from the nearest point of higher elevation. For example, a big, massive rock next to the main summit of a mountain is not considered a summit. Summits near a higher peak, with some prominence or isolation, but not reaching a certain cutoff value for the quantities, are often considered ''subsummits'' (or ''subpeaks'') of the higher peak, and are considered part of the same mountain. A pyramidal peak is an exaggerated form produced by ice erosion of a mountain top. Summit may also refer to the highest point along a line, trail, or route. The highest summit in the world is Mount Everest with a height of above sea level. The first official ascent was made by Tenzing Norgay and Sir Edmund Hillary ...

Eagle Island, Antarctica
Eagle Island is one of several islands around the peninsula known as Graham Land, which is closer to South America than any other part of that continent. It is an island in the continent of Antarctica, separated from the Antarctic mainland by the 1.77 km wide Aripleri Passage. It is volcanic in origin, having been K-Ar dated 1.7 ± 0.2 and 2.0 ± 0.2 million years old. It forms part of the James Ross Island Volcanic Group. During the Southern Hemisphere summer of 2019-2020 three melting events occurred on Trinity peninsula, in November 2019, January 2020, and particularly February 6- February 11, 2020, during which 106 millimeters of snow melted, forming melt ponds on Eagle Island. The nine day heatwave in early February 2020 melted about 20% of the island's snow cover. Map Trinity Peninsula.Scale 1:250000 topographic map No. 5697.

Prince Gustav Channel
The Prince Gustav Channel was named in 1903 after Crown Prince Gustav of Sweden (later King Gustav V) by Otto Nordenskiöld of the Swedish Antarctic Expedition. The channel is bounded on the west by the Antarctic Peninsula and on the east by James Ross Island. It is about long and ranges from wide. On 27 February 1995, the British Antarctic Survey (BAS) reported that an ice shelf formerly blocking the channel had disintegrated. This ice shelf had spanned approximately prior to its disintegration. In the area previously covered by the shelf, the channel's water depth is between . Between February and March 2000, scientists collected sediment cores 5 to 6 m in length from the ocean floor. Carbon dating of organic material found in the sediment layers suggested that for a period between 2,000 and 5,000 years ago, much of the channel was seasonally open water. While icebergs were able to navigate the channel, ice rafted debris was deposited within the sediment. Prince Gustav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trinity Peninsula
Trinity Peninsula is the northernmost part of the Antarctic Peninsula. It extends northeastward for about 130 km (80 mi) to Cape Dubouzet from an imaginary line connecting Cape Kater on the north-west coast and Cape Longing on the south-east coast. Prime Head is the northernmost point of this peninsula. Some 20 kilometers southeast of Prime Head is Hope Bay with the year-round Argentinian Esperanza Base. History It was first sighted on 30 January 1820 by Edward Bransfield, Master, Royal Navy, immediately after his charting of the newly discovered South Shetland Islands nearby. In the century following the peninsula's discovery, chartmakers used various names (Trinity Land, Palmer Land, and Land of Louis Philippe) for this portion of it, each name having some historical merit. The recommended name derives from "Trinity Land", given by Bransfield during 1820 in likely recognition of the Corporation of Trinity House, Britain's historical maritime pilotage authority, altho ...

Falkland Islands Dependencies Survey
The British Antarctic Survey (BAS) is the United Kingdom's national polar research institute. It has a dual purpose, to conduct polar science, enabling better understanding of global issues, and to provide an active presence in the Antarctic on behalf of the UK. It is part of the Natural Environment Research Council (NERC). With over 400 staff, BAS takes an active role in Antarctic affairs, operating five research stations, one ship and five aircraft in both polar regions, as well as addressing key global and regional issues. This involves joint research projects with over 40 UK universities and more than 120 national and international collaborations. Having taken shape from activities during World War II, it was known as the Falkland Islands Dependencies Survey until 1962. History Operation Tabarin was a small British expedition in 1943 to establish permanently occupied bases in the Antarctic. It was a joint undertaking by the Admiralty and the Colonial Office.
