Primary Productivity 2 (F049)
This file format is used for data from measurements of photosynthetic capacity and phytoplankton productivity. In addition to cruise information, position, date, time, sampling depths, bottom depth, and general environmental information, this file may contain measured parameters including: concentrations of chlorophylls A, B, C, plant carotenoids, and phaeo-pigments; concentrations of oxygen, particulate organic carbon, ammonia, nitrite, nitrate, silicate, and urea; temperature, salinity, and total alkalinity; and light penetration and light intensity. Values of photosynthetic capacity and primary productivity may be reported as total values or partial values for phytoplankton, net plankton, nano- plankton, and dissolved organic matter.
File Structure:
Five 105-character records: (1) File Header Record, (2) First Station Record, (3) Environmental Record, (4) Physical/Chemical Record, and (5) Pigments/Carbon Assimilation Record.
