Mount Nickens
The Hudson Mountains are a mountain range in western Ellsworth Land just east of Pine Island Bay at the Walgreen Coast of the Amundsen Sea. They are of volcanic origin, consisting of low scattered mountains and nunataks that protrude through the West Antarctic Ice Sheet. The Hudson Mountains are bounded on the north by Cosgrove Ice Shelf and on the south by Pine Island Glacier. The mountains were volcanically active during the Miocene and Pliocene, but there is evidence for an eruption about two millennia ago and uncertain indications of activity in the 20th century. Geography and geomorphology The Hudson Mountains rise in western Ellsworth Land of West Antarctica and were discovered in 1940 by the United States Antarctic Service Expedition. The mountains lie at some distance from the Amundsen Sea's Walgreen Coast, facing Pine Island Bay. The Cosgrove Ice Shelf lies north of the Hudson Mountains. The mountains are remote and visits are rare. In 1991, they were prospected ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Parasitic Vent
A parasitic cone (also adventive cone, satellite cone, satellitic cone or lateral cone) is the cone-shaped accumulation of volcanic material not part of the central vent of a volcano. It forms from eruptions from fractures on the flank of the volcano. These fractures occur because the flank of the volcano is unstable. Eventually, the fractures reach the magma chamber and generate eruptions called flank eruptions, which, in turn, produce a parasitic cone. A parasitic cone can also be formed from a dike or sill cutting up to the surface from the central magma chamber in an area different from the central vent. A peculiar example of multiple parasitic cones is Jeju Island in South Korea. Jeju Island features 368 "oreums" (Korean: ; "mount"), which lie in a roughly lateral line on either side of the island's central dormant shield volcano Hallasan.

Webber Nunatak
Webber Nunatak is a nunatak (495 m). It stands 6 nautical miles (11 km) west of Mount Manthe in the Hudson Mountains. It was mapped using air photos taken by U.S. Navy Operation Highjump, which took place during 1946 and 1947. It was named in 1967 by the Advisory Committee on Antarctic Names (US-ACAN) for George E. Webber, an electrical engineer at Byrd Station. Webber Nunatak is one of several volcanic cone Volcanic cones are among the simplest volcanic landforms. They are built by ejecta from a volcanic vent, piling up around the vent in the shape of a cone with a central crater. Volcanic cones are of different types, depending upon the nature and s ...s in the Hudson Mountains. Satellite imagery suggested an eruption at Webber Nunatak in 1985, although this remains unconfirmed.

Global Warming
Present-day climate change includes both global warming—the ongoing increase in global average temperature—and its wider effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to Earth's climate. The current rise in global temperatures is driven by human activities, especially fossil fuel burning since the Industrial Revolution. Fossil fuel use, deforestation, and some agricultural and industrial practices release greenhouse gases. These gases absorb some of the heat that the Earth radiates after it warms from sunlight, warming the lower atmosphere. Carbon dioxide, the primary gas driving global warming, has increased in concentration by about 50% since the pre-industrial era to levels not seen for millions of years. Climate change has an increasingly large impact on the environment. Deserts are expanding, while heat waves and wildfires are becoming more common. Amplified warming in the Arctic has c ...

Volcanic Crater
A volcanic crater is an approximately circular depression in the ground caused by volcanic activity. It is typically a bowl-shaped feature containing one or more vents. During volcanic eruptions, molten magma and volcanic gases rise from an underground magma chamber, through a conduit, until they reach the crater's vent, from where the gases escape into the atmosphere and the magma is erupted as lava. A volcanic crater can be of large dimensions, and sometimes of great depth. During certain types of explosive eruptions, a volcano's magma chamber may empty enough for an area above it to subside, forming a type of larger depression known as a caldera. Geomorphology In most volcanoes, the crater is situated at the top of a mountain formed from the erupted volcanic deposits such as lava flows and tephra. Volcanoes that terminate in such a summit crater are usually of a conical form. Other volcanic craters may be found on the flanks of volcanoes, and these are commonly refe ...
