Orr Glacier
Rennick Glacier () is a broad glacier, nearly long, which is one of the largest in Antarctica. It rises on the polar plateau westward of Mesa Range and is wide, narrowing to near the coast. It takes its name from Rennick Bay where the glacier reaches the sea. Early exploration The seaward part of the glacier was photographed by United States Navy Operation Highjump, 1946–47. The upper reaches of the Rennick Glacier were discovered and explored by the U.S. Victoria Land Traverse (VLT) in February 1960, and the first ascent made of Welcome Mountain by John Weihaupt, Alfred Stuart, Claude Lorius and Arnold Heine of the VLT party. On February 10, 1960, Lieutenant Commander Robert L. Dale, pilot of U.S. Navy (USN) Squadron VX-6, evacuated the VLT from , on this glacier, and then conducted an aerial photographic reconnaissance to Rennick Bay on the coast before returning the VLT team to McMurdo Station. Course The Rennick Glacier rises to the east of the Tobin Mesa in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glacier Morphology
Glacier morphology, or the form a glacier takes, is influenced by temperature, precipitation, topography, and other factors. The goal of glacial morphology is to gain a better understanding of glaciated landscapes and the way they are shaped. Types of glaciers can range from massive ice sheets, such as the Greenland ice sheet, to small cirque glaciers found perched on mountain tops. Glaciers can be grouped into two main categories: * Ice flow is constrained by the underlying bedrock topography * Ice flow is unrestricted by surrounding topography Unconstrained Glaciers Ice sheets and ice caps Ice sheets and ice caps cover the largest areas of land in comparison to other glaciers, and their ice is unconstrained by the underlying topography. They are the largest glacial ice formations and hold the vast majority of the world's fresh water. Ice sheets Ice sheets are the largest form of glacial formation. They are continent-sized ice masses that span areas over . They are dome ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

United States Geological Survey
The United States Geological Survey (USGS), founded as the Geological Survey, is an agency of the U.S. Department of the Interior whose work spans the disciplines of biology, geography, geology, and hydrology. The agency was founded on March 3, 1879, to study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The agency also makes maps of planets and moons, based on data from U.S. space probes. The sole scientific agency of the U.S. Department of the Interior, USGS is a fact-finding research organization with no regulatory responsibility. It is headquartered in Reston, Virginia, with major offices near Lakewood, Colorado; at the Denver Federal Center; and in NASA Research Park in California. In 2009, it employed about 8,670 people. The current motto of the USGS, in use since August 1997, is "science for a changing world". The agency's previous slogan, adopted on its hundredth anniversary, was "Earth Science in the Pub ...

Serrat Glacier
Rennick Bay () is an embayment of the coastline of Antarctica at the terminus of Rennick Glacier. It is bounded on the west and east by Belousov Point and Stuhlinger Ice Piedmont. Discovery and naming The eastern part of the bay was discovered from the ship '' Terra Nova'', of the British Antarctic Expedition (1910–13) under Scott. It was named by the British Antarctic Expedition for Lieutenant Henry E. de P. Rennick, Royal Navy, an officer on the Terra Nova. The bay was photographed by United States Navy Operation Highjump (1947) and by the Soviet Antarctic Expedition (1958).
