| Summary: | Abstract. Two recent surveys of velocity, temperature and salinity in the Denmark Strait are used to characterize the flow structure, transport and dynamics of the dense overflow from the Nordic Seas. The mean transport of dense water found at the sill is indistinguishable from measurements made in 1973 (to within 20%), and the statistics of variability are similarly identical. Estimates of entrainment rate from watermass dilution in the descending plume are consistent with the near-doubling of transport deduced from previous current meter arrays. In addition, the rate of descent of the dense plume agrees with that of a streamtube retarded by bottom stress. |
