1. A new heat flux model for the Antarctic Peninsula incorporating spatially variable upper crustal radiogenic heat production

   A new method for modelling heat flux shows the upper crust contributes up to 70% of the Antarctic Peninsula’s subglacial heat flux, and that heat flux values are more variable […]

2. Identification of C 25 highly branched isoprenoid (HBI) alkenes in diatoms of the genus Rhizosolenia in polar and sub-polar marine phytoplankton.

   We report the identification of a range of C25 highly branched isoprenoid (HBI) alkenes and certain sterols in filtered phytoplankton samples obtained from western Svalbard (Arctic) and near South Georgia […]

4. Using super-high resolution satellite imagery to census threatened albatrosses

   This study is the first to utilize 30-cm resolution imagery from the WorldView-3 (WV-3) satellite to count wildlife directly. We test the accuracy of the satellite method for directly counting […]

5. Subglacial sediment pathways and deglacial chronology of the northern Barents Sea Ice Sheet

   New information is presented on the configuration of the northern Barents Sea Ice Sheet (BSIS) during the last glacial and deglaciation (21–11.5 ka). The glacial dynamics of the BSIS that […]

6. How accurate are estimates of glacier ice thickness? Results from ITMIX, the Ice Thickness Models Intercomparison eXperiment

   Knowledge of the ice thickness distribution of glaciers and ice caps is an important prerequisite for many glaciological and hydrological investigations. A wealth of approaches has recently been presented for […]

7. Multi-model study of mercury dispersion in the atmosphere: atmospheric processes and model evaluation

   Current understanding of mercury (Hg) behavior in the atmosphere contains significant gaps. Some key characteristics of Hg processes, including anthropogenic and geogenic emissions, atmospheric chemistry, and air–surface exchange, are still […]

8. Multifrequency Radar Imagery and Characterization of Hazardous and Noxious Substances at Sea

   The increase in maritime traffic, particularly the transport of hazardous and noxious substances (HNSs), requires advanced methods of identification and characterization in environmental chemical spills. Knowledge about HNS monitoring using […]

9. Using globally threatened pelagic birds to identify priority sites for marine conservation in the South Atlantic Ocean

   The Convention on Biological Diversity aspires to designate 10% of the global oceans as Marine Protected Areas (MPAs), but so far, few MPAs protect pelagic species in the high seas. […]

10. Early last glacial intra-interstadial climate variability recorded in a Sardinian speleothem

    Chemical and physical proxy data from a precisely dated early last glacial (∼113–110 ka, MIS5d) Sardinian stalagmite reveal a sub-millennial-scale, cool-dry climate event centered at 112.0 +0.52/-0.59 ka, followed by […]

11. Widespread biological response to recent rapid warming on the Antarctic Peninsula

    Recent climate change on the Antarctic Peninsula is well documented [1, 2, 3, 4, 5], with warming, alongside increases in precipitation, wind strength, and melt season length [1, 6, 7], […]

12. The impact of atmospheric storminess on the sensitivity of Southern Ocean circulation to wind stress changes

    The influence of changing the mean wind stress felt by the ocean through alteration of the variability of the atmospheric wind, as opposed to the mean atmospheric wind, on Southern […]
