Abstract:
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 and easily deployed on the same wire, to any ocean depth, in almost
any weather. Each is capable of drawing up to 200 liters per hour through
four large Nuclepore™ filters, then through three cartridge filters.
Pumping is controlled by a Sharp™ pocket computer suitably interfaced with
the pump motor and flow meter. Endurance is about 15 hours. Total flow
and flow rate are recorded, respectively, by a mechanical flow meter and
the computer.
