Stratigraphy and regional significance of the Upper Jurassic-Lower Cretaceous Byers Group, Livingston Island, Antarctica
Read more of: Stratigraphy and regional significance of the Upper Jurassic-Lower Cretaceous Byers Group, Livingston Island, AntarcticaThe Byers Group, exposed on Byers Peninsula, western Livingston Island, Antarctica, comprises a mudstone dominated sequence at least 1 km thick which accumulated in a marginal fore-arc environment. The basal, […]

Extreme relativistic electron fluxes in the Earth’s outer radiation belt: Analysis of INTEGRAL IREM data
Read more of: Extreme relativistic electron fluxes in the Earth’s outer radiation belt: Analysis of INTEGRAL IREM dataRelativistic electrons (E > 500 keV) cause internal charging and are an important space weather hazard. To assess the vulnerability of the satellite fleet to these so-called “killer” electrons, it […]

Bipolar molluscs and their evolutionary implications
Read more of: Bipolar molluscs and their evolutionary implicationsThe phenomenon of bipolarity, one of the major disjunct distribution patterns on the face of the earth, has been investigated repeatedly since the mid-nineteenth century. Running through the many hypotheses […]

Latitudinal range fluctuations in the marine realm through geological time
Read more of: Latitudinal range fluctuations in the marine realm through geological timeOur concept of polar marine faunas as having evolved in comparative isolation over long periods may need to be revised. New evidence from the Southern Ocean, in particular, suggests that […]

Testing Munk’s hypothesis for submesoscale eddy generation using observations in the North Atlantic
Read more of: Testing Munk’s hypothesis for submesoscale eddy generation using observations in the North AtlanticA high-resolution satellite image that reveals a train of coherent, submesoscale (6 km) vortices along the edge of an ocean front is examined in concert with hydrographic measurements in an […]

Revealing higher than expected meiofaunal diversity in Antarctic sediments: a metabarcoding approach
Read more of: Revealing higher than expected meiofaunal diversity in Antarctic sediments: a metabarcoding approachAn increasing number of studies are showing that Antarctic mega- and macrofauna are highly diverse, however, little is known about meiofaunal biodiversity in sediment communities, which are a vital part […]

An assessment of recent and future temperature change over the Sichuan Basin, China, using CMIP5 climate models
Read more of: An assessment of recent and future temperature change over the Sichuan Basin, China, using CMIP5 climate modelsThe Sichuan basin is one of the most densely populated regions of China, making the area particularly vulnerable to the adverse impacts associated with future climate change. As such, climate […]

Simulated climate change: the interaction between vegetation type and microhabitat temperatures at Ny Ålesund, Svalbard
Read more of: Simulated climate change: the interaction between vegetation type and microhabitat temperatures at Ny Ålesund, SvalbardSmall polythene tents were used to simulate the effects of climate warming on two contrasting vegetation types (polar semi-desert and tundra heath) at Ny Ålesund, Spitzbergen, Svalbard. Temperature microclimates are […]

Radar absorption due to impurities in Antarctic ice
Read more of: Radar absorption due to impurities in Antarctic iceMeasurements of radar echo strength have been carried out on Ronne and George VI Ice Shelves, Antarctica. The differences in ice-column absorption between the two sites cannot be resolved by […]

Investment in sexual reproduction by Antarctic mosses
Read more of: Investment in sexual reproduction by Antarctic mossesWe propose four measures of allocation to sexual reproduction in mosses, and apply these to data obtained from 15 species found fruiting on Signy Island, South Orkney Islands, in the […]
