Situated 70 km east of Breid Bay in northern part of Roi Baudouin Ice Shelf, directly in front of Western Ragnhild Glacier. Named for geodesist of Belgian Antarctic expedition Jean-Jacques Derwael.

Ice Rise
An ice rise is a clearly defined elevation of the otherwise very much flatter ice shelf, typically dome-shaped and rising several hundreds of metres above the surrounding ice shelf . An ice rise forms where the ice shelf touches the seabed due to a locally increased elevation of the seabed, which however remains below sea level. (In contrast, an elevation in the seabed that extends above sea level is defined as an island). The ice shelf flows over the seabed elevation, completely covering it with ice, thereby forming an ice rise. The resulting stress increases cause crevasse formation around the ice rise. An island within and totally covered by the ice shelf may appear the same as an ice rise. Elaborate measurements may be required to distinguish between these two geographic features. Although ice rises are typically located within the ice shelf area, they can partially face the open sea. At present, ice rises are found only within the ice shelves of Antarctica. The largest ice ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ice Shelf
An ice shelf is a large floating platform of ice that forms where a glacier or ice sheet flows down to a coastline and onto the ocean surface. Ice shelves are only found in Antarctica, Greenland, Northern Canada, and the Russian Arctic. The boundary between the floating ice shelf and the anchor ice (resting on bedrock) that feeds it is the grounding line. The thickness of ice shelves can range from about to . In contrast, sea ice is formed on water, is much thinner (typically less than ), and forms throughout the Arctic Ocean. It is also found in the Southern Ocean around the continent of Antarctica. The movement of ice shelves is principally driven by gravity-induced pressure from the grounded ice. That flow continually moves ice from the grounding line to the seaward front of the shelf. In steady state, about half of Antarctica's ice shelf mass is lost to basal melt and half is lost to calving, but the relative importance of each process varies significantly between ice s ...

Princess Ragnhild Coast
Princess Ragnhild Coast is the portion of the coast of Queen Maud Land in Antarctica lying between 20° E and the Riiser-Larsen Peninsula, at 34° E. All but the eastern end of the coast is fringed by ice shelves. It was discovered by Capt. Hjalmar Riiser-Larsen and Capt. Nils Larsen in aerial flights from the ship ''Norvegia'' on February 16, 1931, and named for Princess Ragnhild of Norway. Vestvika Bay is a large bay on the west side of Riiser-Larsen Peninsula; it was mapped from air photos taken by the Lars Christensen Expedition, 1936–37, and named Vestvika, meaning "west bay." Important Bird Area A 379 ha site on fast ice, within a crack in the ice shelf some 230 km west of the Riiser-Larsen Peninsula, has been designated an Important Bird Area (IBA) by BirdLife International because it supports a breeding colony of emperor penguin The emperor penguin (''Aptenodytes forsteri'') is the tallest and heaviest of all living penguin species and is endemic to ...

Antarctica
Antarctica () is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean, it contains the geographic South Pole. Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of . Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of . Antarctica is, on average, the coldest, driest, and windiest of the continents, and it has the highest average elevation. It is mainly a polar desert, with annual precipitation of over along the coast and far less inland. About 70% of the world's freshwater reserves are frozen in Antarctica, which, if melted, would raise global sea levels by almost . Antarctica holds the record for the lowest measured temperature on Earth, . The coastal regions can reach temperatures over in summer. Native species of animals include mites, nematodes, penguins, seals and tardigrades. Where vegetation o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Breid Bay
Breid Bay is a bay A bay is a recessed, coastal body of water that directly connects to a larger main body of water, such as an ocean, a lake, or another bay. A large bay is usually called a Gulf (geography), gulf, sea, sound (geography), sound, or bight (geogra ... about wide, irregularly indenting, for as much as , the ice shelf fringing the coast of Queen Maud Land. This feature was charted and descriptively named "Breidvika" ("broad bay") by H.E. Hansen, as a result of aerial photographs made on February 6, 1937, by the Lars Christensen Expedition of 1936–37.

Roi Baudouin Ice Shelf
The King Baudouin Ice Shelf (also called Roi Baudouin Ice shelf, from French: Plateforme de glace Roi Baudouin) in Dronning Maud Land, East Antarctica, is within the Norwegian part of Antarctica. It is named after King Baudouin of Belgium (1930-1993). Geology The King Baudouin ice shelf is confined by two ice rises (including Derwael Ice Rise) and one under-ice pinning-point with a width of only a few kilometres; the latter seems to define the seaward edge of the ice shelf and impacts ice flow in the hinterland.Be:Wise -The Buttressing Effect: Why ice shelves are essential antarcticstation.org, 12 November 2012, accessed 14 January 2015 Roi Baudoin Base Belgium was one of the original 12 sig ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ice Rises Of Antarctica
Ice is water frozen into a solid state, typically forming at or below temperatures of 0 degrees Celsius or Depending on the presence of impurities such as particles of soil or bubbles of air, it can appear transparent or a more or less opaque bluish-white color. In the Solar System, ice is abundant and occurs naturally from as close to the Sun as Mercury to as far away as the Oort cloud objects. Beyond the Solar System, it occurs as interstellar ice. It is abundant on Earth's surfaceparticularly in the polar regions and above the snow lineand, as a common form of precipitation and deposition, plays a key role in Earth's water cycle and climate. It falls as snowflakes and hail or occurs as frost, icicles or ice spikes and aggregates from snow as glaciers and ice sheets. Ice exhibits at least eighteen phases ( packing geometries), depending on temperature and pressure. When water is cooled rapidly (quenching), up to three types of amorphous ice can form depending on its his ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
