| Summary: | Although the structural framework of the subsurface offshore West Greenland has been well documented based on com-prehensive seismic analysis (cf. Dalhoff et al. 2003), the stratigraphy of the region is less well known. The oldest doc-umented sedimentary rocks drilled offshore West Greenland are Santonian sandstones reached at TD in the 6354/4-1 well (Fig. 1) although reworked palynomorphs of Carboniferous, Triassic and Jurassic (Kimmeridgian) age have been reported from a number of wells in the region. In order to obtain better constraints on the pre-Upper Cretaceous stratigraphy, a preliminary screening was undertaken to identify inversion structures and erosional canyons where such deeper strati-graphic levels crop out at the seabed (Nielsen et al. 2001). Sea-floor sampling at selected sites between 62 ° and 67°N (Fig. 1) was undertaken during the summers of 2003 and |
