    Abstract : Permafrost soils in the Arctic store large quantities of organic matter, roughly twice the amount of carbon that was present in the atmosphere before the industrial revolution. This freeze-locked carbon pool is susceptible to thawing caused by amplified global warming at high latitudes. READ MORE

  4. 2. High Arctic submarine glaciogenic landscapes : their formation and significance

    Author : Francis Fletcher Freire; Richard Gyllencreutz; Martin Jakobsson; Haflidi Haflidason; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; High Arctic; GrIS; marine geophysics; glaciogenic landscapes; ice streams; submarine slides; Marine Geology; maringeologi;

    Abstract : This thesis is focused on studies of glacial and slope morphology in the high Arctic of western Greenland shelf and the Molloy Hole seafloor spreading area, based on high-resolution acoustic methods and other geophysical data. The main purpose is to improve our understanding of glacial dynamics and associated processes in the marginal region of a large marine-terminating ice sheet. READ MORE
