Abstract. Coastal ecosystems can experience acidification via upwelling, eutrophication, riverine discharge, and climate change. While the resulting increases in pCO2 can have deleterious effects on calcifying animals, this change in carbonate chemistry may benefit some marine autotrophs. Here, we report on experiments performed with North Atlantic populations of hard clams (Mercenaria mercenaria), eastern oysters (Crassostrea virginica), bay scallops (Argopecten irradians), and blue mussels (Mytilus edulis) grown with and without North Atlantic populations of the green macroalgae, Ulva. In 6 of 7 experiments, exposure to elevated pCO2 levels (~ 1,700 µatm) resulted in depressed shell- and/or tissue-based growth rates of bivalves compared to control conditions (p

Quality Of Water

Shellfish (Crassostrea virginica and Mercenaria mercenaria) and shellfish-raising waters from a variety of Long Island and New Jersey marine embayments were examined for the presence of human enteroviruses. Little difference in virological quality was noted between areas designated as being open or closed to shellfishing. Viral isolations could not be correlated with coliform counts from identical samples, indicating the need to re-evaluate the use of bacterial standards as indices of the overall sanitary quality of water and shellfish.

Gas Chromatographic Separation

Abstract A method of analysis for mixtures of chlorinated benzenes in clam (Mercenaria mercenaria) and oyster (Crassostrea virginica) samples is reported. The method involves Soxhlet extraction with n-hexane-isopropanol (1:1) for 6 hours followed by gas chromatographic separation on a Silicone gum column with an electron affinity detector. Quantities as small as 10-10 g are detectable. Average recovery of added Polystream (a mixture of chlorinated benzenes) was 99% for clam samples and 104% for oyster samples. Recoveries were based on reading the 1,2,3,4-tetrachlorobenzene peak. The relative precision for triplicate chromatograms, averaged over all levels, was ± 5%.
