A SELF-PROPULSION MODIFICATION TO THE CLARKE-BUMPUS QUANTITATIVE PLANKTON SAMPLER.
NAVAL POSTGRADUATE SCHOOL MONTEREY CALIF
Pagination or Media Count:
The existence of a plankton sampler which is capable of filtering a reasonably large volume of water but which need not be towed in order to perform this function would provide a means whereby the planktonologist could conduct his collection in areas which preclude towing operations or under circumstances where towing is inconvenient. A modification to the standard Clarke-Bumpus quantitative plankton sampler which provides such a capability is described and a calibration procedure is discussed. Results of comparative testing indicate the satisfactory operation of the modified sampler. Author
