Mass balance of Devon Ice Cap, Canadian Arctic
Interferometric synthetic aperture radar data show that Devon Ice Cap (DIC), northern Canada, is drained through a network of 11 glacier systems. More than half of all ice discharge is […]

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 […]

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 […]
