Average gross production (mg C/1/day) in the altered area (canals) was 8% higher than in the marsh and 48% higher than in the bay during June, July, and August 1969. Gross and net production were significantly higher in the canals and marsh than in the bay; differences between the canals and marsh were not significant.phytoplanktonplanktonologyecological distributionmarshescanalsArticle
