Late Cretaceous extinction patterns in Antarctica
New correlations of marine clastic sedimentary rocks exposed within the James Ross Basin, Antarctica have shown that the mid-to late Cretaceous succession is in excess of 5 km thick. Plotting […]

Antarctica and the evolution of taxonomic diversity gradients in the marine realm
Read more of: Antarctica and the evolution of taxonomic diversity gradients in the marine realmAlthough it will probably never be as complete as that known from any of the other continents, the Antarctic fossil record comprises a surprising amount of information. Originally gathered primarily […]

Effects of experimental temperature elevation on high-arctic soil microarthropod populations
Read more of: Effects of experimental temperature elevation on high-arctic soil microarthropod populationsAn experiment was conducted to measure the effects of summer warming on the total population densities of soil-dwelling microarthropods in the high Arctic and to compare these results with those […]

Correction of satellite radar altimeter data on ice-covered surfaces in Antarctica using an integrated geographical information system
Read more of: Correction of satellite radar altimeter data on ice-covered surfaces in Antarctica using an integrated geographical information systemThe problem of correcting satellite altimeter measurements for errors introduced by topographic surfaces was chosen to test the capabilities of a prototype integrated geographical information system. A system to calculate […]

Geomorphic and shallow-acoustic investigation of an Antarctic Peninsula fjord system using high-resolution ROV and shipboard geophysical observations: Ice dynamics and behaviour since the Last Glacial Maximum
Read more of: Geomorphic and shallow-acoustic investigation of an Antarctic Peninsula fjord system using high-resolution ROV and shipboard geophysical observations: Ice dynamics and behaviour since the Last Glacial MaximumDetailed bathymetric and sub-bottom acoustic observations in Bourgeois Fjord (Marguerite Bay, Antarctic Peninsula) provide evidence on sedimentary processes and glacier dynamics during the last glacial cycle. Submarine landforms observed in […]

One tunic but more than one barcode: evolutionary insights from dynamic mitochondrial DNA in Salpa thompsoni (Tunicata: Salpida)
Read more of: One tunic but more than one barcode: evolutionary insights from dynamic mitochondrial DNA in Salpa thompsoni (Tunicata: Salpida)The DNA barcode within the mitochondrial cox1 gene is typically used to assess the identity and diversity of animals under the assumption that individuals contain a single form of this […]

Iceberg killing fields limit huge potential for benthic blue carbon in Antarctic shallows
Read more of: Iceberg killing fields limit huge potential for benthic blue carbon in Antarctic shallowsClimate-forced ice losses are increasing potential for iceberg-seabed collisions, termed ice scour. At Ryder Bay, West Antarctic Peninsula (WAP) sea ice, oceanography, phytoplankton and encrusting zoobenthos have been monitored since […]
