Description
Summary:By using high resolution multibeam swath batymetry and 2- and 3D seismic data this thesis investigate the interactions between ice streaming, glacitectonics and fluid flow in Håkjerringdjupet. The source area for a glacitectonic hill-hole pair is located directly above spatial fluid accumulations assosiated to a fault complex. Glacitectonic deposits are found directly downstream from this area. We suggest that sub-glacial gas hydrate formation due to low temperature - high pressure conditions caused basal freeze-on and subsequent glacitectonic rafting.
