The populations of two non-native Dipterans have been established at two Antarctic research stations since at least 1998. Both belong to Sciaridae (“black fungus midge”), and have been determined to […]
New U–Pb zircon ion-microprobe ages from the alluvial conglomerates and flood plain sediments of the Botany Bay Group demonstrate that sedimentation occurred at c. 167 Ma, coeval with rift-related silicic […]
We investigated the possible effects of a 12-g data-logger attached to a darvic ring on the performance of Coryrsquos shearwater (Calonectris diomedea, 600–850 g) from two different colonies in the […]
Svalbard ice cores have not yet been fully exploited for studies of climate and environmental conditions. In one recently drilled ice core from Lomonosovfonna, we have studied the methanesulfonic acid […]
Climatological change in the tides in the lower thermosphere has been estimated at five different latitudes using wavelet analysis of geomagnetic data series extending back to the beginning of the […]
Polar Mesosphere Summer Echoes (PMSE) are a pointer to summer mesospheric conditions and have fuelled the debate over temperature differences between the Antarctic and Arctic mesopause regions. However few PMSE […]
We investigate and quantify the variability of snow accumulation rate around a medium-depth firn core (160 m) drilled in east Dronning Maud Land, Antarctica (75°00′S, 15°00′E; 3470 m h.a.e. (ellipsoidal […]
We present a high-resolution record of water-soluble ion chemistry from a 121 m ice core spanning about 800 years. The core is well dated to 2/3 depth using cycle counting […]
Ocean tide models around Antarctica are presently only sparsely tested against independent data. Ocean tide modeling errors, along with subsequent ocean tide loading (OTL) displacement modeling errors, alias into altimetry […]
During the austral summer of 2003, a large scale survey of the Scotia Sea was undertaken by the British Antarctic Survey as part of the Southern Ocean Global Ocean Ecosystems […]
Bryozoans are one of the major macrofaunal groups of the high polar regions. Here we present data on the nature of bryozoan assemblages in the Svalbard Archipelago sampled over 6 […]
