Abstract

This study is a combined effort resulting from two cruises (SVAIS, of the BIO Hespérides and EGLACOM of the R/V OGS-Explora) within the International Polar Year (IPY) Activity 367 NICESTREAMS to resolve with the highest possible resolution the mechanisms of spatial and temporal changes in marine sedimentation on the Storfjorden and Kveithola Troughs Mouth Fans (TMFs) on the northwestern Barents Sea continental margin, from the Last Glacial Maximum to present. We used a combined geophysical, sedimentological and cronobiostratigrafic approach of the sedimentary sequence. Data analysis suggests strong across- and along-slope variability of the depositional system especially during the early phase of deglaciation
