1.1 This practice covers the procedures for obtaining qualitative samples of a phytoplankton community by use of conical tow nets. Nets will not retain all phytoplankton taxa; for example, nannoplankton and ultraplankton generally will pass through a net.

1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
