ANTASed – An Updated Sediment Model for Antarctica
نویسندگان
چکیده
We compile existing seismic, gravity, radar and magnetic data, together with the subglacial bedrock relief from BEDMACHINE project, to build most detailed sediment model for Antarctica. interpolate these data according a tectonic map of Antarctica using statistical kriging method. Our results reveal significant accumulation in several types sedimentary basins: parts Beacon Supergroup more recent rifting basins. The basement closely resembles major geological structures. thickness sediments has variations around continent, depends on degree crustal extension. West wide Ross basin (thickness 2–6 km), Filchner-Ronne (2–12 km) continuations into East Antarctica, Bentley Subglacial Trench Byrd (2–4 km). deepest complex structure multi-layered sediments. is characterized by vast basins such as Pensacola-Pole (1–2 Coats Land (1–3 Dronning Maud Vostok (2–7 Aurora Astrolabe Adventure Wilkes (1–4 basins, along narrow deep rifts filled sediments: JutulStraumen Lambert (2–5 Scott, Denman, Vanderford Totten rifts. average whole continent about 0.77 km. new model, ANTASed, represents improvement over CRUST 1.0 reveals Differences between ANTASed reach +12/−3

Neptunomonas antarctica sp. nov., isolated from marine sediment.
A Gram-negative, motile, oxidase- and catalase-positive and facultatively aerobic bacterium, designated S3-22T, was isolated from marine sediment of the Nella Fjord, Antarctica. Strain S3-22T reduced nitrate to nitrite and grew at pH 6.0-8.0, at 4-25 degrees C and with 0.5-5% (w/v) NaCl. It contained Q-8 as the only respiratory quinone and summed feature 3 (C16:1omega7c and/or iso-C15:0 2-OH), ...
متن کاملAn updated digital model of plate boundaries
[1] A global set of present plate boundaries on the Earth is presented in digital form. Most come from sources in the literature. A few boundaries are newly interpreted from topography, volcanism, and/or seismicity, taking into account relative plate velocities from magnetic anomalies, moment tensor solutions, and/or geodesy. In addition to the 14 large plates whose motion was described by the ...
