Laboratory carbon dioxide exposure experiments measuring scope for growth for juvenile Atlantic sea scallops (Placopecten magellanicus) from 2019-10-23 to 2019-12-19 (NCEI Accession 0276024)

This dataset contains the biological response for Atlantic sea scallops (Placopecten magellanicus) exposed to three different levels of carbon dioxide enrichment (low, medium, high). The experiment took place from October 23, 2019 to December 19, 2019 (8 weeks). Salinity, temperature, dissolved oxygen, dissolved inorganic carbon, pH, chlorophyll-a, and seston counts are reported for the seawater during the 8 week exposure. Physiological measurements (feeding, respiration, and excretion rates) were taken 4 times during the experiment at the following temperatures (13.1C, 9.4C, 7.4C, and 6.1C). For feeding rates, the clearance rate, organic ingestion rate, assimilation rate, and assimilation efficiency are reported. From the respiration rate and excretion rate the atomic oxygen to nitrogen ratio is also reported. Scope for growth (the amount of energy available to grow) is calculated from the assimilated energy minus the energy for catabolic processes. Growth parameters were also taken during the 8 week experiment every 2 weeks. For growth parameters, dry tissue weight, dry shell weight, length, width, and thickness are reported.
