  • A large-volume, deep-sea submersible pumping system 

    Sachs, Peter L.; Hammar, Terence R.; Bacon, Michael P. (Woods Hole Oceanographic Institution, 1989-11)
    Eight self-contained, in-situ pumps have been used effectively and routinely by our group for the past six years to collect both particulate and dissolved phases from large volumes of sea water. Multiple pumps are rapidly ...
  • A modified wire clamp system for thirty-liter Niskin bottles 

    Hammar, Terence R.; Sachs, Peter L.; Bacon, Michael P. (Woods Hole Oceanographic Institution, 1988-11)
    A modified clamping system for 30-liter Niskin bottles, consisting of a wire stop, a socket block, and a toggle clamp, has been designed and has been tested at sea. The modified system makes deployment and recovery of the ...
