Diet and growth rates of Meganyctiphanes norvegica in autumn
Read more of: Diet and growth rates of Meganyctiphanes norvegica in autumnFatty acid biomarkers analysis was performed on juvenile and adult northern krill (Meganyctiphanes norvegica) to determine variability in diet between individuals and the consequences for their growth rates. Animals were […]

Inbreeding and inbreeding depression of early life traits in a cooperative mammal
Read more of: Inbreeding and inbreeding depression of early life traits in a cooperative mammalMating between relatives often results in negative fitness consequences or inbreeding depression. However, the expression of inbreeding in populations of wild cooperative mammals and the effects of environmental, maternal and […]

Psychiatric illness and suicide in the heroic age of Antarctic exploration
Read more of: Psychiatric illness and suicide in the heroic age of Antarctic explorationDuring the heroic age of Antarctic exploration, a number of the early explorers developed psychiatric illness either in the Antarctic or shortly after leaving it. Most of these were psychotic […]

Psychology during the expeditions of the heroic age of Antarctic exploration
Read more of: Psychology during the expeditions of the heroic age of Antarctic explorationThe psychology of Antarctic explorers and groups in Antarctic bases has been much studied in recent years, and current knowledge has been summarized in a review by Palinkas and Suedenfeld […]

Longitudinal surface structures (flowstripes) on Antarctic glaciers
Read more of: Longitudinal surface structures (flowstripes) on Antarctic glaciersLongitudinal surface structures (“flowstripes”) are common on many glaciers but their origin and significance are poorly understood. In this paper we present observations of the development of these longitudinal structures […]

Trend and abrupt changes in long-term geomagnetic indices
Read more of: Trend and abrupt changes in long-term geomagnetic indicesAdvanced statistical methods are employed to analyze three long-term time series of geomagnetic activity indices (aa, IHV, and IDV) together with sunspot number (Rz) to examine whether or not the […]

Atmosphere-ionosphere conductivity enhancements during a hard solar energetic particle event
Read more of: Atmosphere-ionosphere conductivity enhancements during a hard solar energetic particle eventOn 20 January 2005, a solar energetic particle (SEP) event caused the largest recorded solar proton ground level event since 1956. Serendipitously, a balloon-borne experiment intended to measure effects of […]

Diurnal and semidiurnal tide-induced lateral movement of Ronne Ice Shelf, Antarctica
Read more of: Diurnal and semidiurnal tide-induced lateral movement of Ronne Ice Shelf, AntarcticaRecent GPS observations from a spatially extensive network across Ronne Ice Shelf show significant daily ice flow variations. At all sites, the almost-synchronous horizontal displacements occur at diurnal and semidiurnal […]

Where might we find evidence of a Last Interglacial West Antarctic ice sheet collapse in Antarctic ice core records?
Read more of: Where might we find evidence of a Last Interglacial West Antarctic ice sheet collapse in Antarctic ice core records?Abundant indirect evidence suggests that the West Antarctic Ice Sheet (WAIS) reduced in size during the Last Interglacial (LIG) compared to the Holocene. This study explores this possibility by comparing, […]

Investigations of squid stocks using acoustic survey methods
Read more of: Investigations of squid stocks using acoustic survey methodsAcoustic survey methods are now widely used for stock assessments of finfish, both those with and without swimbladders, but their application to squid stocks has been limited in the past, […]

Results of the Marine Ice Sheet Model Intercomparison Project, MISMIP
Read more of: Results of the Marine Ice Sheet Model Intercomparison Project, MISMIPPredictions of marine ice-sheet behaviour require models that are able to robustly simulate grounding line migration. We present results of an intercomparison exercise for marine ice-sheet models. Verification is effected […]
