Graduate Doctoral Dissertations
The relation among essential habitat, ocean acidification, and calcification in Argopecten irradians (Lamarck 1819) was examined through field and laboratory research. Three major questions were addressed: 1) What habitat conditions are associated with abundant populations of bay scallops in Nantucket Harbor? 2) How might future predictions of ocean pH decline affect the biomineralization of shell by bay scallop across juvenile and adult life stages? 3) Are there biochemical indicators that can inform our understanding on how the bay scallop may cope with ocean acidifying events? Elemental fingerprinting of adult and juvenile Nantucket bay scallop shells, A. irradians, revealed distinct element/Ca …

Graduate Masters Theses
The burning of fossil fuels, and other natural processes, has led to an increase of carbon dioxide (CO2) in the atmosphere. The equilibration of atmospheric CO2 with surface waters causes the ocean pH to decrease from the current value of 8.1. Evidence suggests that as the ocean becomes more alkaline, organisms such as the bay scallop, Argopecten irradians¸will become more stressed due to increased energy demands to maintain shell deposition and growth. This stress, as hypothesized here, may cause the deposition of S-bearing organic macromolecules to aid in mineralization as well as the potential for sulfate …
