The rates of gross primary production ranged from 2.75 to 6.98 g [O.sub.2] [m.sup.-2] [d.sup.-1] in the ponds, and the rates of respiration from 3.61 to 6.91 g [O.sub.2] [m.sup.-2] [d.sup.-1].
We measured gross primary production (GPP) and chlorophyll a concentration at two stations in each of five estuaries of Waquoit Bay (Childs River, Quashnet River, Jehu Pond, Hamblin Pond, and Sage Lot Pond).
Our data show that gross primary production was higher in the Childs River, and that it fluctuated daily in both estuaries ([Mathematical Expression Omitted], CV = 39%, [Mathematical Expression Omitted], CV = 62% for Quashnet).
