The McMurdo Volcanic Group is a large group of Cenozoic volcanic rocks in the western Ross Sea and central Transantarctic Mountains areas of Antarctica. [1] It is one of the largest provinces of alkaline volcanism in the world, having formed as a result of continental rifting along the West Antarctic Rift System .
The giant volcano sponge (Anoxycalyx joubini) is a species of Antarctic sponge. [1] It is one of the largest sponges in the world which can grow up to a diameter of 1.5 metres (5 feet) and 1.95 metres (6.5 feet) in height. [2] The species may have an extremely long lifespan, with estimates of up to 15,000 years. [3]
McMurdo Sound experiences katabatic winds from the Antarctic polar plateau. McMurdo Sound freezes over with sea ice about 3 metres (9.8 ft) thick during the winter. During the austral summer when the pack ice breaks up, wind and currents may push the ice northward into the Ross Sea, stirring up cold bottom currents that spill into the ocean basins.
The volcano is part of the McMurdo Volcanic Group, and together with The Pleiades, Mount Overlord, Mount Rittmann and the Malta Plateau forms a subprovince, the Melbourne volcanic province. The volcanism is related both to the West Antarctic Rift and to local tectonic structures such as faults and grabens .
Scientists are tracking changes at the giant supervolcano that lies under Yellowstone National Park, but they say there's no need to worry at the moment. “The western part of the Yellowstone ...
Ross Island is an island in Antarctica lying on the east side of McMurdo Sound and extending 43 nautical miles (80 km; 49 mi) from Cape Bird in the north to Cape Armitage in the south, and a similar distance from Cape Royds in the west to Cape Crozier in the east. The island is entirely volcanic.
McMurdo Dry Valleys, Landsat 7 imagery acquired on December 18, 1999. The Dry Valleys are so named because of their extremely low humidity and lack of snow or ice cover. They are also dry because, in this location, the mountains are sufficiently high that they block seaward-flowing ice from the East Antarctic Ice Sheet from reaching the Ross ...
