1. Sensitivity of interglacial Greenland temperature and δ18O: ice core data, orbital and increased CO2 climate simulations

   The sensitivity of interglacial Greenland temperature to orbital and CO2 forcing is investigated using the NorthGRIP ice core data and coupled ocean-atmosphere IPSL-CM4 model simulations. These simulations were conducted in […]

2. The “tipping” temperature within Subglacial Lake Ellsworth, West Antarctica and its implications for lake access.

   We present results from new geophysical data allowing modelling of the water flow within Subglacial Lake Ellsworth (SLE), West Antarctica. Our simulations indicate that this lake has a novel temperature […]

3. Snow optical properties at Dome C, (Concordia), Antarctica: implications for snow emissions and snow chemistry of reactive nitrogen

   Measurements of e-folding depth, nadir reflectivity and stratigraphy of the snowpack around Concordia station (Dome C, 75.10 S, 123.31 E) were undertaken to determine wavelength dependent coefficients (350 nm to […]

4. Improved magnetic anomalies of the Antarctic lithosphere from satellite and near-surface data

   The Antarctic magnetic anomaly map compiled marine and airborne surveys collected south of 60 degrees S through 1999 and used Magsat data to help fill in the regional gaps between […]

5. Perspectives on marine zooplankton lipids

   We developed new perspectives to identify important questions and to propose approaches for future research on marine food web lipids. They were related to (i) structure and function of lipids, […]

6. The surprising polar troposphere

   Chemical processes in the troposphere are driven by a combination of factors. Emissions from the Earth’s surface, either natural or anthropogenic, are the primary source of trace gases in the […]

7. Melting of floating ice and sea level rise

   [1] Contrary to popular belief, the melting of floating ice (in the form of ice shelves, icebergs and sea ice) may have a non-zero impact on sea level. This is […]

8. Applying new tools to cephalopod trophic dynamics and ecology: perspectives from the Southern Ocean Cephalopod Workshop, February 2-3, 2006

   A two day workshop on Southern Ocean cephalopods was held in Hobart, Tasmania, Australia prior to the triennial 2006 Cephalopod International Advisory Council (CIAC) symposium. The workshop provided a second […]

9. Statistical significance of the association between whistler-mode chorus enhancements and enhanced convection periods during high-speed streams

   During high-speed solar wind streams, substorms occur repetitively and relativistic electron fluxes enhance significantly. It has recently been proposed that enhanced dawnside chorus waves lead to the energization of the […]

10. The influence of regional circulation patterns on wet and dry mineral dust and sea salt deposition over Greenland

    Annually resolved ice core records from different regions over the Greenland ice sheet (GrIS) are used to investigate the spatial and temporal vari- ability of calcium (Ca2+, mainly from mineral […]

12. Response of the inner and outer magnetosphere to solar wind density fluctuations during the recovery phase of a moderate magnetic storm

    We examine the geomagnetic field and space plasma disturbances developing simultaneously in the solar wind, in the inner and outer magnetosphere, and on the ground from 0730 to 2030 UT […]
