At Geochemical Ocean Sections Study station 28, in the basin east of the Newfoundland Ridge, dramatic evidence for the 'underthrusting' of the benthic boundary layer was encountered. Results from the continuous temperature, salinity, and nephel measurements and from discrete water samples are presented in order to document that strong shearing within the near-bottom water column must occur in this area. These observations amplify previous observations that Denmark Strait overflow water penetrates as a thin wedge far to the south of its place of origin.
