Description
Data of macrobenthic communities of Casco Bay and Portland Harbor, Maine sampled in April 1980 in order to provide an environmental benchmark more

The soft bottom macrobenthic communities of Casco Bay and Portland Harbor, Maine were sampled in April 1980 in order to provide an environmental benchmark. Fifty-six subtidal stations were occupied using a 0.1 m2 Smith-McIntyre grab. Depths ranged from 7 to 140 feet. Subsamples were taken for grain size, CHN, trace metal and hydrocarbon analyses. The samples were sieved on a 1.0 mm screen and the fauna removed and identified to the lowest taxonomic level possible. The results yielded 266 putative species several of which represented range extensions. Density ranged from 120 to 36,380/m2 with a mean of 8,743/m2. Total Distribution Records: 1847 Total Number of Taxa: 266 Related URL
