Extraterrestrial spherules in glacial sediment from the Transantarctic Mountains, Antarctica: Structure, mineralogy, and chemical composition
Abstract-Silicate and glassy spherules of probably extraterrestrial origin have been discovered in glacial till from localities in the Beardmore glacier region, Tramantarctic Mountains, Antarctica. These spherules are similar in structure, appearance, and composition to spherules found in deepsea sediments and in Greenland. Most spherules have a shiny and smooth dark surface, while some show a ...
متن کاملConnected subglacial lake drainage beneath Thwaites Glacier, West Antarctica
We present conventional and swath altimetry data from Cryosat-2 revealing a system of subglacial lakes that drained between June 2013 and January 2014 under the central part of Thwaites Glacier, West Antarctica. Much of the 10 drainage happened in less than six months, with an apparent connection between three lakes spanning more than 130 km. Hydropotential analysis of the glacier bed shows a l...
متن کاملRapid subglacial erosion beneath Pine Island Glacier, West Antarctica
[1] We present measurements of ice thickness, gravimetry and surface elevation on Pine Island Glacier, West Antarctica, separated by a period of 49 years. At one station, on the main trunk of the glacier we measured a surface elevation lowering with no significant change in ice thickness. We interpret these as indicating subglacial erosion of 31.8 13.4 m at this location, at a mean rate over th...
متن کاملPliocene Nothofagus Wood from the Transantarctic Mountains
Subfossil wood fragments up to 10 cm long and 2 cm in diameter recovered from a locality thought on the basis of diatom deposits to be upper Pliocene-lower Pleistocene (Oliver Bluffs, Sirius Formation, 85°1 O'S., between 1800 and 1900 m in the Transantarctic Mountains) were sectioned for identification. Degradation prevented observation of some wood features, but others were well preserved. All...
متن کاملShear-wave velocities under the Transantarctic Mountains and Terror Rift from surface wave inversion
Rayleigh wave data between 20 and 120s period recorded in the western Ross Sea region of Antarctica are inverted using the waveform inversion technique described in Passier and Snieder [1995]. From the data we extract estimates of local S velocity structure beneath the Transantarctic Mountains and the Terror Rift. The shear wave velocities found are up to 6 % slower than the PREM model at betwe...
