VMPS – VERTICAL MULTIPLE-OPENING PLANKTON SAMPLER
Manufacturer : 14 / Category : 38The VMPS is a plankton net sampler that makes collections with vertical tows. The system is ideally suited for monitoring the vertical distribution of plankton and for collecting living specimens.
The on-deck system consists of a controller unit and an optional,user supplied computer. The system is raised through the water column with an oceanographic winch,making precise positioning and operation possible.
Prior to deployment the nets are spring loaded.A trigger holds the nets in a closed position unit a signal from the Net Controller turns on the trigger motor.This releases the trigger and opens the net.Each net is open until the next is triggered.
During operation,flow volume,depth,and net position data are sent to the sufface and displayed on the Net Conetroller and can be stored on a personal computer.
