Frazil ice formation in an ice shelf water plume
[1] We present a model for the growth of frazil ice crystals and their accumulation as marine ice at the base of Antarctic ice shelves. The model describes the flow […]

Global and hemispheric climate variations affecting the Southern Ocean
Read more of: Global and hemispheric climate variations affecting the Southern OceanThe hemispheric and regional atmospheric circulation influences the Southern Ocean in many and profound ways, including intense air-sea fluxes of momentum, energy, fresh water and dissolved gases. The Southern Ocean […]

Ice flow direction change in interior West Antarctica
Read more of: Ice flow direction change in interior West AntarcticaUpstream of Byrd Station (West Antarctica), ice-penetrating radar data reveal a distinctive fold structure within the ice, in which isochronous layers are unusually deep. The fold has an axis more […]

Diurnal variability of subglacial drainage conditions as revealed by tracer experiments
Read more of: Diurnal variability of subglacial drainage conditions as revealed by tracer experimentsThe morphology of the drainage system of Unteraargletscher, Switzerland, and the diurnal variability of drainage conditions were investigated by conducting a series of tracer tests over a number of discharge […]

Meteoric marine and total ice thickness maps of Filchner-Ronne-Schelfeis, Antarctica
Read more of: Meteoric marine and total ice thickness maps of Filchner-Ronne-Schelfeis, AntarcticaMapping the geometry of the ice sheet is fundamental to many advanced investigations, e.g., on ice dynamics, mass balance, ice – ocean interaction, ice – atmosphere interaction, and ice body […]

Salinity, depth and the structure and composition of microbial mats in continental Antarctic lakes
Read more of: Salinity, depth and the structure and composition of microbial mats in continental Antarctic lakes1. Lakes and ponds in the Larsemann Hills and Bolingen Islands (East-Antarctica) were characterised by cyanobacteria-dominated, benthic microbial mats. A 56-lake dataset representing the limnological diversity among the more than […]

The annual cycle of a trans-equatorial Eurasian–African passerine migrant: different spatio-temporal strategies for autumn and spring migration
Read more of: The annual cycle of a trans-equatorial Eurasian–African passerine migrant: different spatio-temporal strategies for autumn and spring migrationThe small size of the billions of migrating songbirds commuting between temperate breeding sites and the tropics has long prevented the study of the largest part of their annual cycle […]

Assessment of soil bacterial communities on Alexander Island (in the maritime and continental Antarctic transitional zone)
Read more of: Assessment of soil bacterial communities on Alexander Island (in the maritime and continental Antarctic transitional zone)Despite an increasing number of Antarctic soil diversity assessments, understanding of the bacterial community composition in the arid soil environments of the maritime/continental Antarctic transitional zone remains lacking. Most documented […]
