A unified model of the response of ionospheric convection to changes in the interplanetary magnetic field
Read more of: A unified model of the response of ionospheric convection to changes in the interplanetary magnetic fieldTwo competing paradigms of the response of ionospheric convection to changes in the interplanetary magnetic field are synthesized into the common framework of the expanding-contracting polar cap (ECPC) model in […]

Heterotrophic microbial colonization of the interior of impact-shocked rocks from Haughton impact structure, Devon Island, Nunavut, Canadian High Arctic
Read more of: Heterotrophic microbial colonization of the interior of impact-shocked rocks from Haughton impact structure, Devon Island, Nunavut, Canadian High ArcticThe polar desert is one of the most extreme environments on Earth. Endolithic organisms can escape or mitigate the hazards of the polar desert by using the resources available in […]

The Dufek and Forrestal intrusions, Antarctica: a centre for Ferrar Large Igneous Province dike emplacement?
Read more of: The Dufek and Forrestal intrusions, Antarctica: a centre for Ferrar Large Igneous Province dike emplacement?Newly acquired aeromagnetic data indicate the presence of a dike swarm that may have acted as a magma transport and feeder system from the plume impact site up to 3,500 […]

Large-scale geomagnetic effects of May 4, 1998
Read more of: Large-scale geomagnetic effects of May 4, 1998We study large-scale magnetospheric disturbances elicited by the May4, 1998 high speed stream by modeling the Dst and studying records from 4 meridional magnetometer chains covering key local time sectors. […]

Power to the magnetosphere: May 4, 1998
Read more of: Power to the magnetosphere: May 4, 1998An extraordinary powering of the magnetosphere by the solar wind occurred in a 3-hour burst early on May 4 when the IMF was very intense and pointed south (≈-35 nT; […]

Supraglacial debris along the front of the Larsen-A Ice Shelf, Antarctic Peninsula
Read more of: Supraglacial debris along the front of the Larsen-A Ice Shelf, Antarctic PeninsulaSemi-continuous, linear accumulations of poorly-sorted debris are present on the surface of the remnant Larsen-A Ice Shelf, Antarctic Peninsula. These accumulations form a complex of debris bands extending parallel to […]

Rapid, large-scale temperature changes in the polar mesosphere and their relationship to meridional flows
Read more of: Rapid, large-scale temperature changes in the polar mesosphere and their relationship to meridional flowsMesospheric temperatures derived from spectroscopic measurements of the hydroxyl (OH) nightglow have been observed from Rothera (67.6°S, 68.1°W) and Halley (75.6°S, 26.6°W) stations in Antarctica during the 2002 austral winter […]
