  • A computer model along a flow-line of an ice dome: captured ice shelf
  • Floating ice ; Glacial flow ; Glacier mass balance ; Ice ; Numerical model ; Skane ; Sweden
  • The paper examines the captured ice shelf hypothesis through the construction of a numerical model. Based on ice surface elevation, ice thickness, and ground topography, the velocity is calculated. The thickness is adjusted, taking into account
  • Ross ice shelf oxygen isotopes and West Antarctic climate history

  • Late Wisconsinan age glacial Landforms and deposits indicate that an ice shelf of at least 60,000 km flowed northwestward into Viscount Melville Sound, probably from the M'Clintock Dome of the Laurentide Ice Sheet. The ice shelf overlapped coastal
  • areas and laid Winter Harbour Till up to 150 m above present sea level on the north coast of Victoria Island. The contemporary sea-level was 50 to 100 m higher than present. A maximum age of 10,340150 yr BP for the till, and thus for the ice shelf
  • advance, is provided by shells in marine sediments which underlie it, whereas a minimum age of 9880150 yr BP is provided by overlying shells that postdate the ice advance.
  • The captured ice shelf hypothesis and its applicability to the Weichselian glaciation
  • Concept ; Floating ice ; Glaciation ; Glacier margin ; Ice ; Meltwater ; Quaternary ; Skane ; Sweden
  • -filled cavities. The terms captured ice shelf and captured lake are introduced, suggesting that a floating ice is the norm, rather than an exception, in this concept.
  • The early and late stages of the Weichselian glaciation of the Baltic Sea proper and the Baltic countries is tentatively suggested as having been by means of a thin ice with very low basal friction, to a great extent floating on a number of water
  • Spatial Sciences on Ice : 50 years of Australian activities on the Amery Ice Shelf, East Antarctica
  • Antarctica ; Climatic change ; Cold area ; Global Positioning System ; Global change ; Ice ; Ice shelf ; Polar region ; Remote sensing
  • This paper presents a history of the use of spatial science techniques from basic survey equipment to satellite systems in Australian research projects based on the Amery Ice Shelf (and surrounding glaciers) since 1955. The application
  • information provides scientists with a better understanding of the ice shelf/ocean/atmosphere system allowing future monitoring to observe the effects of global climate change.
  • An ice-shelf moraine, George VI sound, Antarctica
  • The morphology, sediments and processes associated with the construction of a moraine along the western margin of the ice-shelf in George VI Sound, Antarctica, are discussed. A conceptual model of the moraine is developed and may help to explain

  • Estimation de l'état d'équilibre de trois bandes d'écoulement du Ross Ice Shelf. A partir d'estimations, il semble que le glacier s'épaissit au rythme de 3415 cm par an. Les plus grands courants d'écoulement sont vers le Sud et l'Est de Roosevelt

  • Melting rates at the bottom of Filchner-Ronne ice shelf, Antarctica, from short-term mass-balance studies
  • Antarctica ; Glacier mass balance ; Glaciology ; Ice ; Methodology ; Scientific expedition
  • Field studies which were performed in 1990 on a strain network yielded all quantities which are necessary to solve the mass-conservation equation with respect to the melting rate underneath the Filchner-Ronne ice shelf, Antarctica. The network
  • was located about 30 km inland from the ice front and about 50 km north-west of Filchner Station. - (L'A.).

  • Submarine landforms preserved in bathymetric troughs on the Antarctic continental shelf show that the style of ice stream retreat across the shelf following the last glacial maximum varied between different troughs. Three styles of retreat
  • are inferred from the geological evidence : rapid, episodic and slow. They indicate that Antarctic palaeo-ice-streams did not respond uniformly to external forcing at the end of the last glacial cycle. Rather, their diachronous retreat reflects the dominance
  • of local controls in the form of bathymetry and drainage basin size. These data provide important constraints for numerical models that attempt to predict the dynamics of large polar ice sheets.
  • Response of a marine ice sheet to changes at the grounding line

  • A numerical model was designed to study the stability of a marine ice sheet, and used to do some basic experiments. The ice-shelf/ice-sheet interaction enters through the flow law in which the longitudinal stress is also taken into account
  • . An attempt is made to simulate a whole cycle of growth and retreat of a marine ice sheet. The question as to what might happen to the West Antarctic Ice Sheet in the near future where a climatic warming can be expected as a result of the CO effect, seems
  • to be open for discussion again. From the results presented in this paper one can infer that a collapse, caused by increased melting on the ice shelves, is not very likely.
  • Variations in valley glaciers activity in the Transantarctic Mountains as indicated by associated flow bands in the Ross Ice Shelf in Sea level ice and climatic change.
