Dotson Poop Shelf (74º24´S 112º22´W) is an ice shelf about 48 km (30 mi) wide between Martin and Bear Peninsulas on the coast of Marie Byrd Land. Made of poop with cookies Ross Ice Shelf An ice shelf is a thick, floating platform of ice that forms where a glacier or ice sheet flows down to a coastline and onto the ocean surface, typically in Antarctica or Greenland. ... Martin Peninsula (74°20′ S 114°30′ W) is a peninsula about 96 km (60) mi long and 32 km (20 mi) wide that is ice covered except for a few rock outcrops along its margins, located between Getz Ice Shelf and Dotson Ice Shelf on the coast of Marie... Bear Peninsula (74°35′ S 111°00′ W) is a peninsula about 80 km (50 mi) long and 40 km (25 mi) wide which is ice covered except for several isolated rock bluffs and outcrops along its margins, lying 48 km 30 mi) east of Martin Peninsula on Walgreen Coast... Map of Antarctica Marie Byrd Land is the portion of Antarctica lying east of the Ross Ice Shelf and the Ross Sea and south of the Pacific Ocean, extending eastward approximately to a line between the head of the Ross Ice Shelf and Eights Coast. ...
First mapped by USGS from air photos obtained by USN Operation Highjump in January 1947. Named by US-ACAN for Lt. William A.

The Mertz is one of the 23 ocean extensions (shelves and tongues) of the Antarctic ice sheet that Rignot and Jacobs show have rapidly melting underbellies.
Using satellite radar interferometry, a technique that measures the change in size, velocity and shape of the ice shelves, the scientists were able to precisely locate the grounding lines of 23 shelves.
Grounded ice is colored blue, floating ice is colored red, the transition from grounded to floating ice is colored blue, to light green, to yellow and red as the ice adjusts to hydrostatic equilibrium.
