Remote sensing space weather events: Antarctic-Arctic radiation-belt (Dynamic) Deposition-VLF Atmospheric Research Konsortium network
Read more of: Remote sensing space weather events: Antarctic-Arctic radiation-belt (Dynamic) Deposition-VLF Atmospheric Research Konsortium network[1] The Antarctic-Arctic Radiation-belt (Dynamic) Deposition-VLF Atmospheric Research Konsortium (AARDDVARK) provides a network of continuous long-range observations of the lower ionosphere in the polar regions. Our ultimate aim is to […]

The West Gondwana margin : Proterozoic to Mesozoic
Read more of: The West Gondwana margin : Proterozoic to MesozoicThe longevity and extent of the oceanic southern margin of Gondwana have made it the subject of intense study for more than 70 years. It was one of the cradles […]

How insects survive the cold: molecular mechanisms – a review
Read more of: How insects survive the cold: molecular mechanisms – a reviewInsects vary considerably in their ability to survive low temperatures. The tractability of these organisms to experimentation has lead to considerable physiology-based work investigating both the variability between species and […]

Characterisation of the warm acclimated protein gene (wap65) in the Antarctic plunderfish (Harpagifer antarcticus)
Read more of: Characterisation of the warm acclimated protein gene (wap65) in the Antarctic plunderfish (Harpagifer antarcticus)Physiological adaptation to increased environmental temperatures has been studied experimentally in a number of fish species, with the up-regulation of several genes identified as being associated with the process, such […]

A change in seasonality in Greenland during a Dansgaard–Oeschger warming
Read more of: A change in seasonality in Greenland during a Dansgaard–Oeschger warmingA new sub-seasonal chemical record is presented from the North Greenland Icecore Project (NorthGRIP) ice core during the onset of one of the longest and strongest interstadials of the last […]

Normal forms for reduced stochastic climate models
Read more of: Normal forms for reduced stochastic climate modelsThe systematic development of reduced low-dimensional stochastic climate models from observations or comprehensive highdimensional climate models is an important topic for atmospheric low-frequency variability, climate sensitivity, and improved extended range […]

Comparison of mid-Pliocene climate predictions from the HadAM3 and GCMAM3 General Circulation Models
Read more of: Comparison of mid-Pliocene climate predictions from the HadAM3 and GCMAM3 General Circulation ModelsThe mid-Pliocene warm period (ca. 3 to 3.3 million years ago) has become an important interval of time for palaeoclimate modelling exercises, with a large number of studies published during […]

High-latitude oceanography using the Autosub autonomous underwater vehicle
Read more of: High-latitude oceanography using the Autosub autonomous underwater vehicleA combination of measurements from Autosub, an autonomous underwater vehicle, and ship-based instruments are used to describe the oceanographic conditions beneath Fimbul Ice Shelf, Antarctica. The data show an intricate […]

Influence of trophic position and foraging range on mercury levels within a seabird community
Read more of: Influence of trophic position and foraging range on mercury levels within a seabird communitySeabirds are often advocated as biomonitors for marine contaminants such as mercury (Hg). However, contaminant levels can vary widely depending on among-individual and among-species variation in foraging preferences and physiology, […]

Tracer-derived freshwater composition of the Siberian continental shelf and slope following the extreme Arctic summer of 2007
Read more of: Tracer-derived freshwater composition of the Siberian continental shelf and slope following the extreme Arctic summer of 2007We investigate the freshwater composition of the shelf and slope of the Arctic Ocean north of the New Siberian Islands using geochemical tracer data (δ18O, Ba, and PO4*) collected following […]

Analytical solutions for the surface response to small amplitude perturbations in boundary data in the shallow-ice-stream approximation
Read more of: Analytical solutions for the surface response to small amplitude perturbations in boundary data in the shallow-ice-stream approximationNew analytical solutions describing the effects of small-amplitude perturbations in boundary data on flow in the shallow-ice-stream approximation are presented. These solutions are valid for a non-linear Weertman-type sliding law […]
