Recovery Glacier
Template:Short description Template:Use dmy dates Script error: No such module "Infobox".Template:Template otherScript error: No such module "Check for unknown parameters".
The Recovery Glacier (Template:Coord) is a glacier, at least Template:Convert long and Template:Convert wide at its mouth, flowing west along the southern side of the Shackleton Range in Antarctica.Template:Sfn
Discovery and name
The Recovery Glacier was first seen from the air and examined from the ground by the Commonwealth Trans-Antarctic Expedition in 1957. It was so named because of the recovery of the expedition's vehicles which repeatedly broke into bridged crevasses on this glacier during the early stages of the crossing of Antarctica.Template:Sfn
Glaciology
Dana Floricioiu and Irena Hajnsek of the German Aerospace Centre spoke on the radar data showing the interior of the Recovery Glacier at the IEEE Geoscience and Remote Sensing Symposium in Cape Town, South Africa, in July 2009. The data comes from the German public-private satellite Terrasar-X and when combined with Radarsat-1 shows the changes in the glacier over 11 years.
Features
Recovery Ice Stream
This ice stream drains part of the East Antarctic Ice Sheet into the glacier. It is nearly Template:Convert long and feeds the Filchner Ice Shelf over the Weddell Sea. The area contains four subglacial lakes.Template:Sfn This causes the ice flow rate to vary dramatically, ranging between 2 and 50 meters per year. The ice stream drains about 35 billion tons of water and ice into the ocean each year.Template:Sfn The entire East Antarctic ice sheet releases about 57 billion tons a year.Template:Sfn
Glen Glacier
Script error: No such module "Labelled list hatnote". Template:Coord. A glacier at least Template:Convert long, flowing south in the Shackleton Range to join the Recovery Glacier to the west of the Read Mountains. First mapped in 1957 by the Commonwealth Trans-Antarctic Expedition (CTAE) and named for Alexander R. Glen, member of the Committee of Management of the CTAE, 1955-58.Template:Sfn
Cornwall Glacier
Script error: No such module "Labelled list hatnote". Template:Coord. A glacier Template:Convert long, flowing south from Crossover Pass in the Shackleton Range to join Recovery Glacier east of Ram Bow Bluff. First mapped in 1957 by the CTAE and named for Gen. Sir James Marshall-Cornwall, member of the Committee of Management of the CTAE, 1955-58.Template:Sfn
Blackwall Ice Stream
Template:Coord. A slightly S-shaped ice stream about Template:Convert long and Template:Convert wide. It descends from about Template:Convert high to Template:Convert high where it joins Recovery Glacier between Argentina Range and Whichaway Nunataks. It was named after Hugh Blackwall Evans (1874-1975), Canadian naturalist with the British Antarctic Expedition, 1898–1900, led by Carsten Borchgrevink.Template:Sfn
Whichaway Nunataks
Template:Coord. A group of rocky nunataks extending for Template:Convert and marking the south side of the mouth of Recovery Glacier. First seen from the air and visited in 1957 by the CTAE and so named because it was uncertain which route from the nunataks would lead furthest inland.Template:Sfn
