Synchronisation of the EDML and EDC ice cores for the last 52 kyr by volcanic signature matching
Read more of: Synchronisation of the EDML and EDC ice cores for the last 52 kyr by volcanic signature matchingA common time scale for the EPICA ice cores from Dome C (EDC) and Dronning Maud Land (EDML) has been established. Since the EDML core was not drilled on a […]

Rich and rare – first insights into species diversity and abundance of Antarctic abyssal Gastropoda (Mollusca)
Read more of: Rich and rare – first insights into species diversity and abundance of Antarctic abyssal Gastropoda (Mollusca)The abyssal depths of the polar oceans are thought to be low in diversity compared with the shallower polar shelves and temperate and tropical deep-sea basins. Our recent study on […]

Impact of instantaneous sea ice removal in a coupled general circulation model
Read more of: Impact of instantaneous sea ice removal in a coupled general circulation model1] The impact of extreme sea ice initial conditions on modelled climate is analysed for a fully coupled atmosphere ocean sea ice general circulation model, the Hadley Centre climate model […]

Intra-annual variability in the density of Antarctic krill (Euphausia superba) at South Georgia, 2002-2005: within-year variation provides a new framework for interpreting previous ‘annual’ estimates of krill density
Read more of: Intra-annual variability in the density of Antarctic krill (Euphausia superba) at South Georgia, 2002-2005: within-year variation provides a new framework for interpreting previous ‘annual’ estimates of krill densityUpward-looking acoustic Doppler current profilers (300 kHz) and echo sounders (125 kHz) were deployed on moorings on- and off-shelf to the northwest of South Georgia between 14 October 2002 and […]

Boundary layer halogens in coastal Antarctica
Read more of: Boundary layer halogens in coastal AntarcticaHalogens influence the oxidizing capacity of Earth’s troposphere, and iodine oxides form ultrafine aerosols, which may have an impact on climate. We report year-round measurements of boundary layer iodine oxide […]

“EDML1”: a chronology for the EPICA deep ice core from Dronning Maud Land, Antarctica, over the last 150 000 years
Read more of: “EDML1”: a chronology for the EPICA deep ice core from Dronning Maud Land, Antarctica, over the last 150 000 yearsA chronology called EDML1 has been developed for the EPICA ice core from Dronning Maud Land (EDML). EDML1 is closely interlinked with EDC3, the new chronology for the EPICA ice […]

Oxygen three-isotope fractionation lines in terrestrial silicate minerals: an inter-laboratory comparison of hydrothermal quartz and eclogitic garnet
Read more of: Oxygen three-isotope fractionation lines in terrestrial silicate minerals: an inter-laboratory comparison of hydrothermal quartz and eclogitic garnetGeochemical—and perhaps biochemical—processes may yield tell-tale proxies in rocks and minerals on the Earth or other planetary bodies, in the form of distinctive slopes of linear fractionation arrays on the […]

A new surface accumulation map for western Dronning Maud Land, Antarctica, from interpolation of point measurements
Read more of: A new surface accumulation map for western Dronning Maud Land, Antarctica, from interpolation of point measurementsAs a result of intensive field activities carried out by several nations over the past 15 years, a set of accumulation measurements for western Dronning Maud Land, Antarctica, was collected, […]

Influences of ozone depletion, the solar cycle and the QBO on the Southern Annular Mode
Read more of: Influences of ozone depletion, the solar cycle and the QBO on the Southern Annular ModeWe present results of multiple regressions of the leading mode of atmospheric variability at southern high latitudes: the Southern Annular Mode (SAM). It is regressed against indices with large interannual […]

Introduction: Antarctic ecology from genes to ecosystems. Part 2. Evolution, diversity and functional ecology
Read more of: Introduction: Antarctic ecology from genes to ecosystems. Part 2. Evolution, diversity and functional ecologyThe Antarctic biota has evolved over the last 100 million years in increasingly isolated and cold conditions. As a result, Antarctic species, from micro-organisms to vertebrates, have adapted to life […]
