    • Fine-grained sediment and industrial waste distribution and dispersal in New Bedford Harbor and Western Buzzards Bay, Massachusetts 

      Summerhayes, Colin P.; Ellis, Jeffrey P.; Stoffers, Peter; Briggs, Scott R.; Fitzgerald, Michael G. (Woods Hole Oceanographic Institution, 1977-04)
      New Bedford Harbor and its approaches form the estuary of the Acushnet River in southeastern Massachusetts. The estuary is weakly stratified and only partially mixed because river discharge is very small. It appears to ...
    • The structural and sedimentological evolution of the Somali Basin : paleoceanographic interpretations 

      Burroughs, Richard H. (Woods Hole Oceanographic Institution, 1977-07)
      The paleooceanographic development of the Somali Basin in the Northwestern Indian Ocean is determined through considering the structural, evolution of the area; its influence on Neogene atmospheric and oceanic circulation ...
    • Fluxes, dynamics and chemistry of particulates in the ocean 

      Gardner, Wilford D. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1977-10)
      Sediment traps designed to yield quantitative data of particulate fluxes have been deployed and successfully recovered on four moorings in the deep sea. The traps were designed after extensive calibration of different ...
