Both the factors controlling phytoplankton production and the magni- 

 tude of phytoplankton production are considered for a Georgia estuary. 

 Nutrients are abundant in these estuarine waters and are not important 

 limiting factors. High turbidity limits light penetration, which minimizes 

 photosynthetic activity at depths below two meters. 



Photoplankton production is measured at selected depths using both 

 the carbon-14 method and the light- and dark-bottle oxygen method. These 

 measurements are for periods of less than six hours. The intensity (rate 

 per unit volume) of production is high in the upper two meters where there 

 is sufficient light for high rate of photosynthesis. (A. A.)

Pomeroy, L.R. 1960. Primary productivity of Boca Ciega Bay, Florida. 

 Bulletin of Marine Science of the Gulf and Caribbean 10:1-10. 



The relative importance of turtle grass, phytoplankton, and the 

 benthic microflora as primary producers was determined in Boca Ciega 

 Bay, Florida. The relative importance of phytoplankton, marine 

 spermatophytes, and the benthic microflora as primary producers varies 

 with the depth of the water. In water less than two meters in 

 depth, which makes up 75 percent of the bay, the three are about equally 

 important. In deeper water only phytoplankton is significant. The 

 methods used and the estimation of community production are discussed.

A study of the phytoplankton community in Flax Pond, a Long Island 

 salt marsh, from June 1972 to October 1973 revealed relatively little 

 net primary production. Thirteen variables were sampled at three 

 locations in the marsh e\/ery other hour throughout the photoperiod
