ICES Guidelines for Biological Plankton data. (Compiled August 2001; reviewed April 2006)

Abstract

In the context of this guideline, phytoplankton or zooplankton sampling may be accomplished using either a vertical, horizontal or oblique tow of a net or from a ro sette bottle. In the case of a net, such a device would consist of frame which houses a mesh used in collecting the sample. An example maybe a square frame with multiple nets, of a single, conical shaped mesh with a circular ring opening. Typical mesh s izes would be less than 1000  m (microns). At the mouth end the opening may be of up to 2 m. Attached at the small end of the net would be a jar or cod - end with a typical opening of about 10 cm.
