Experimental and teaching uses

The composition of the tows varies seasonally. Usually, they contain protozoans, bacteria, larval forms, copepods, medusae, zooplankton, and phytoplankton. Supplied in quantities obtained in a thirty-minute tow.

Phototropism in Marine Plankton. Some species of plankton are positively phototrophic while others exhibit a negative response. This phenomenon can be illustrated by covering a jar of plankton with black card stock, leaving a slit where the ends meet. Some species will be attracted to a light placed at the slit while others will not. Examination of each group of organisms should be made by taking samples from light and dark areas.

Seasonal changes in Plankton Composition. Plankton tows will be made at the same site at specified intervals

Advanced Research on Plankton. Plankton and data collection will be made for researchers requiring the use of advanced equipment and techniques. Researchers requiring such assistance should write, supplying details of their project.
