Phytoplankton (F028)

This file format is used for data from the sampling and analysis of marine phytoplankton. Information on phytoplankton abundance, distribution, and productivity derived from these data support studies of marine populations and ecosystems. Data reported may include: position, date, and time of sampling; bottom depth and sampling depths; volume of water filtered; and concentration of cells, carbon concentration, wet and dry weight, and counts for each species reported. Comments may be relayed in a text record.

File Structure:

Four 80-character records: (1) Master Record, (2) Text Record, Detail Record 1, and (4) Detail Record 2.
