Excerpt from Zooplankton Volumes Off the Pacific Coast, 1959 The method used for determining the wet plankton volume of a sample by displacement is as follows: The plankton is separated from its preserving liquid (3-percent formalin) by filtering, allowed to drain, then placed into a graduated cylinder to which is added a known volume of 3-percent formalin. Two volumes are obtained for each sample: (1) the total volume of all plankton material and (2) the volume of smaller organisms after removal of larger organisms, such as jellies, fish, squid, salps, pyrosomes, larger mollusks, and larger crustaceans. Larger organisms are those with individual volumes greater than 5 cubic centimeters (except juvenile or adult fish).

Excerpt from Zooplankton Volumes Off the Pacific Coast, 1952: Special Scientific Report The plankton hauls were made obliquely from approximately 140 meters deep (200 meters of wire out at greatest depth) to the surface. The hauls were made at a.vessei speed of to 2 knots. In taking a haul. The net was lowered to a depth of approximately meters in about 4 minutes and then brought upward at the rate of 14 meters per minute (20 meters of wire retrieved).
