Effects of food supply on northern bay scallops (Argopecten irradians) reared under two pCO2 conditions from 2021-09-14 to 2021-10-26 (NCEI Accession 0289954)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Metadata Last Checked: January 29, 2026 | Last Modified: 2024-03-23T00:00:00.000+00:00
The effects of food supply on bivalves under long-term ocean acidification exposure remains incompletely understood. In this study, juvenile northern bay scallops (50 days post fertilization), Argopecten irradians, that had been reared since 4 hours post-fertilization under one of two ocean acidification conditions (~500-600 or ~750-850 µatm pCO2; ~1.37-1.5 or ~1.0-1.2 Ωaragonite), were subjected to two food levels for 42-days (low food = ~400 and high food = ~1,400 chlorophyll cells mL-1). Standard metabolic rate (SMR) and clearance rate (CR) were measured at day 0 and standard metabolic rate, clearance rate, growth, and survivorship were measured at 14 and 42 days of exposure to two food levels for each of the ocean acidification treatments. This data archive contains (i) seawater carbonate chemistry and discrete seawater chemistry records throughout the experiment (ii) standard metabolic rates, (iii) clearance rates, (iv) survival, (v) shell length, (vi) shell and tissue dry weights ,(vii) and experiment metadata.
