Efficient, shipboard sampling of tiny zooplankters is within reach. This description highlights a towed pump and shipboard filtering system designed for quantitative collection of very small organisms, including crustaceans, during cruising speeds. The material here outlines the apparatus, its operation, and how it supports density estimates with known precision across areas and depths.
The book details how the system combines a collector with a pump, a suspension hose-cable, a winch, and a filtering unit to gather discrete samples in time and space. It explains why smaller mesh sizes are needed and how filtering rate can be measured independently of mesh. It also covers practical use at sea, sample handling, and issues like fouling and maintenance, offering a clear view of design decisions and operational results from 1961 field work.

Paperback. Etat : New. Print on Demand. This book describes the construction, operation, and performance of a towed pump and shipboard filtering system for sampling small zooplankters. The system is composed of a collector containing a pump towed by a suspension unit featuring a steel cable for support and an electric line to power the pump, as well as a winch and filtering unit. Zooplankters between 100 and 200 microns in length are collected quantitatively, collected samples are discrete for consecutive 1-minute intervals of vessel travel at cruising speed, and discrete samples representing very short segments of the vessel track at vessel cruising speed can be taken. The towed pump and shipboard filtering system is a practical sampling tool that can be used to estimate known precision of small zooplankters for areas as small as 20 square miles or as large as several hundred square miles.
