    "title": "Biological effects of ocean acidification on juvenile Atlantic surfclams (Spisula solidissima) observed in laboratory experiments from 2019-04-10 to 2019-07-03 (NCEI Accession 0245952)",
    "description": "This dataset contains laboratory experimental data that were collected to examine the effects of elevated levels of carbon dioxide on the growth of Atlantic surfclam (Spisula solidissima), a species that supports both commercial and recreational fisheries in the Northeast United States. Three levels of carbon dioxide enrichment (low, medium, and high) were delivered to surfclams in a 12-week exposure experiment. All treatments were done in 3 replicates (A, B, C). Approximately every 2 to 3 weeks, 12 individuals were removed from each treatment and measurements of length, width, height, dry tissue, and dry shell were recorded. Length was measured across the longest part of the shell, parallel to the hinge. Width was the thickness of the shell, and height was measured form the hinge to the outer edge of the shell. Dry tissue and dry shell samples were dried at 60\u00b0C until constant weight was achieved (~5 days). DIC measurements of carbon dioxide enrichment were taken and analyzed on an Apollo SciTech, while pH was measured weekly with a spectrophotometer. Values reported for DIC, pH, temperature, and salinity are the mean of each treatment during the 12-week experiment. The data indicated that increased carbon dioxide affected growth, tissue mass, and shell weight for Atlantic surfclam.",
