Soil properties of an Antarctic inland site: implications for ecosystem development
Read more of: Soil properties of an Antarctic inland site: implications for ecosystem developmentInland Antarctic nunataks typically have simple physically weathered soils and limited ecosystem complexity. In this paper we present quantitative measurements of soil physical and chemical properties at one Antarctic nunatak. […]

Pc1-Pc2 waves and energetic particle precipitation during and after magnetic storms: superposed epoch analysis and case studies
Read more of: Pc1-Pc2 waves and energetic particle precipitation during and after magnetic storms: superposed epoch analysis and case studiesMagnetic pulsations in the Pc1-Pc2 frequency range (0.1-5 Hz) are often observed on the ground and in the Earth’s magnetosphere during the aftermath of geomagnetic storms. Numerous studies have suggested […]

DWM07 global empirical model of upper thermospheric storm-induced disturbance winds
Read more of: DWM07 global empirical model of upper thermospheric storm-induced disturbance windsWe present a global empirical disturbance wind model (DWM07) that represents average geospace-storm-induced perturbations of upper thermospheric (200-600 km altitude) neutral winds. DWM07 depends on the following three parameters: magnetic […]

Coordination Action for Research Activities on life in Extreme Environments – the CAREX project
Read more of: Coordination Action for Research Activities on life in Extreme Environments – the CAREX projectLife, as we know it, is constrained by various environmental parameters ( physical and chemical) and these vary both in space and time. Combinations of specific ranges for each of […]

Ground-based measurements of spatial and temporal variability of snow accumulation in East Antarctica
Read more of: Ground-based measurements of spatial and temporal variability of snow accumulation in East AntarcticaThe East Antarctic Ice Sheet is the largest, highest, coldest, driest, and windiest ice sheet on Earth. Understanding of the surface mass balance (SMB) of Antarctica is necessary to determine […]

Antarctic Tropospheric Chemistry Investigation (ANTCI) 2003 overview
Read more of: Antarctic Tropospheric Chemistry Investigation (ANTCI) 2003 overviewThe Antarctic Tropospheric Chemistry Investigation (ANTCI) was carried out from late November to December 2003 with both extended ground-based and tethered balloon studies at Amundsen Scott Station, South Pole. ANTCI […]

Near-future level of CO2-driven ocean acidification radically affects larval survival and development in the brittlestar Ophiothrix fragilis
Read more of: Near-future level of CO2-driven ocean acidification radically affects larval survival and development in the brittlestar Ophiothrix fragilisThe world’s oceans are slowly becoming more acidic. In the last 150 yr, the pH of the oceans has dropped by similar to 0.1 units, which is equivalent to a […]

Bed Ribbing Instability Explanation: testing a numerical model of ribbed moraine formation arising from coupled flow of ice and subglacial sediment
Read more of: Bed Ribbing Instability Explanation: testing a numerical model of ribbed moraine formation arising from coupled flow of ice and subglacial sedimentRibbed moraines are large (up to 16 km long) ridges of sediment produced transverse to ice flow direction that formed widely beneath palaeo-ice sheets. Since ice sheet stability is sensitive […]

An empirical model of the Earth’s horizontal wind fields: HWM07
Read more of: An empirical model of the Earth’s horizontal wind fields: HWM07The new Horizontal Wind Model (HWM07) provides a statistical representation of the horizontal wind fields of the Earth’s atmosphere from the ground to the exosphere (0-500 km). It represents over […]

A major trough-mouth fan on the continental margin of the Bellingshausen Sea, West Antarctica: The Belgica Fan
Read more of: A major trough-mouth fan on the continental margin of the Bellingshausen Sea, West Antarctica: The Belgica FanA 330-km length of the little known continental shelf edge and slope of the Bellingshausen Sea, West Antarctica, is investigated using multibeam swath-bathymetric and sub-bottom profiler evidence. The shelf break […]

First airborne gravity results over the Thwaites Glacier catchment, West Antarctica
Read more of: First airborne gravity results over the Thwaites Glacier catchment, West AntarcticaRecent satellite observations of Thwaites Glacier in the Amundsen Sea Embayment, West Antarctica, have shown that the glacier is changing rapidly. The causes of its dynamic behavior are uncertain but […]
