Use of ice-sheet normal modes for initialization and modelling small changes
Read more of: Use of ice-sheet normal modes for initialization and modelling small changesLinearizations about two horizontal-dimensional ice sheets are proposed as methods of generating normal mode initializations for ice-sheet models and for computing the short-term response. Linearized models can be generated directly […]

Normal modes of an ice sheet
Read more of: Normal modes of an ice sheetA linearized perturbation about the Vialov-Nye fixed-span solution for a steady-state ice sheet yields a Sturm-Liouville problem. The numerical eigenvalue problem is solved and the resulting normal modes are used […]

Deforming beds: Viscous and plastic scales of deformation
Read more of: Deforming beds: Viscous and plastic scales of deformationSmall scale field and laboratory observations of sub-glacial sediment deformation suggest that failure is the predominant method of sediment deformation, while large scale modelling studies using a viscous model of […]

Ecology and seed morphology of endemic species from Kerguelen Phytogeographic Zone
Read more of: Ecology and seed morphology of endemic species from Kerguelen Phytogeographic ZoneMorphological descriptions of the seeds of eight phanerogamic species are provided together with observations on the dispersal of the seeds and the habitats of parent plants. These are discussed in […]

Seed germination of endemic species from Kerguelen phytogeographic zone
Read more of: Seed germination of endemic species from Kerguelen phytogeographic zoneSeeds of six endemic species and two circumpolar species were collected from several sites on Kerguelen and tested for germination between 5 and 25°C on thermogradient bars. Pringlea antiscorbutica and […]

Nonmarine sedimentation in an Early Cretaceous extensional continental-margin arc, Byers Peninsula, Livingston Island, South Shetland Islands
Read more of: Nonmarine sedimentation in an Early Cretaceous extensional continental-margin arc, Byers Peninsula, Livingston Island, South Shetland IslandsUpper Jurassic-Lower Cretaceous rocks of the Byers Group, exposed on Byers Peninsula, Livingston Island, record the expansion of Gondwana-margin continental-arc facies into a marine intra-arc basin. At least 1.3 km […]

An analysis of a 34-year air temperature record from Fossil Bluff (71°S, 68°W), Antarctica
Read more of: An analysis of a 34-year air temperature record from Fossil Bluff (71°S, 68°W), AntarcticaAn analysis of a long-term surface air temperature record for Fossil Bluff in the George VI Sound, West Antarctic Peninsula (WAP) documents in detail some important aspects of the climate […]

Atmospheric meridional circulation impacts on contrasting winter sea ice extent in two years in the Pacific sector of the Southern Ocean
Read more of: Atmospheric meridional circulation impacts on contrasting winter sea ice extent in two years in the Pacific sector of the Southern OceanAn explanation is sought for the marked variation in maximum sea ice extent observed between 2 years in the 2 areas of greatest interannual variability in winter ice extent in […]

Rock temperatures and implications for cold region weathering. I: New data from Viking Valley, Alexander Island, Antarctica
Read more of: Rock temperatures and implications for cold region weathering. I: New data from Viking Valley, Alexander Island, AntarcticaA principal tenet of cold region weathering studies is that of temperature. Unfortunately, despite the appearance to the contrary, actual data are still sadly lacking in many instances. Here data […]

Observations on “cryoplanation” benches in Antarctica
Read more of: Observations on “cryoplanation” benches in AntarcticaA series of benches on nunataks of Alexander Island (Antarctica) are described. An increase in bench size with distance away from the retreating glacier suggests an age spectrum. The benches […]
