This manuscript was produced as an introduction to this publication emanating from CIAC ’09, the recent triennial symposium of the Cephalopod International Advisory Council. Given the importance of one of […]
Pack ice and icebergs are two of the biggest hazards to shipping around Antarctica. Andrew Fleming and Paul Bowyer demonstrate how a new satellite system is protecting ships in the […]
Inland 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. […]
Magnetic 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 […]
We 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 […]
Life, 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 […]
The 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 […]
The 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 […]
The 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 […]
Ribbed 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 […]
