“…These data suggest Virginia oysters stop calcifying at an upper threshold T of 24-25°C (Figs. 3 and 4), which is close to the temperature of growth cessation determined for Florida oysters (~26-30°C) (24). Most of the seasonal differences in minima (and maxima) δ 18 O calcite values in the WS oysters likely result from interannual shifts in S due to its control on δ 18 O water (Fig.…”

“…Within the Chesapeake Bay system, oyster shell growth occurs between~8 and 25°C (22). Each oyster shell contains a geochemical ( 18 O/ 16 O) record of growth, season of collection, estuarine temperatures and salinities (23,24) and information that can identify locations of source oyster reefs. The James River and watershed have changed dramatically between 1607 and the present in terms of terrestrial vegetation (25), land use (25,26), sedimentation rates (27,28), nutrient sources (29,30), and trophic structure (1,9,27,30,31).…”

Oysters (Crassostrea virginica) were a central component of the Chesapeake Bay ecosystem in 1607 when European settlers established Jamestown, VA, the first permanent English settlement in North America. These estuarine bivalves were an important food resource during the early years of the James Fort (Jamestown) settlement while the colonists were struggling to survive in the face of inadequate supplies and a severe regional drought. Although oyster shells were discarded as trash after the oysters were eaten, the environmental and ecological data recorded in the bivalve geochemistry during shell deposition remain intact over centuries, thereby providing a unique window into conditions during the earliest Jamestown years. We compare oxygen isotope data from these 17th century oyster shells with modern shells to quantify and contrast estuarine salinity, season of oyster collection, and shell provenance during Jamestown colonization (1609-1616) and the 21st century. Data show that oysters were collected during an extended drought between fall 1611 and summer 1612. The drought shifted the 14 psu isohaline above Jamestown Island, facilitating individual oyster growth and extension of oyster habitat upriver toward the colony, thereby enhancing local oyster food resources. Data from distinct well layers suggest that the colonists also obtained oysters from reefs near Chesapeake Bay to augment oyster resources near Jamestown Island. The oyster shell season of harvest reconstructions suggest that these data come from either a 1611 well with a very short useful period or an undocumented older well abandoned by late 1611.Chesapeake Bay | Crassostrea virginica | environmental reconstruction | oxygen isotope | scleroarchaeology

“…Assuming equilibrium conditions, variations in δ 18 O of bivalve shells (δ 18 O ar ) reflect oxygen isotope ratios of ambient water (δ 18 O w ) and temperature during biomineralization (Epstein et al, 1953;Dettman et al, 1999). Although many species of bivalve precipitate their shells in oxygen isotope equilibrium with the ambient environment (Dettman et al, 1999;Surge et al, 2001;Elliot et al, 2003;Chauvaud et al, 2005), some mollusk display an offset attributed to metabolic processes (e.g., vital effects) (Wefer and Berger, 1991;Fenger et al, 2007). Therefore, we must examine modern and living species to verify isotopic equilibrium before interpreting past climate and environmental conditions preserved in their fossil shells (Goewert et al, 2007).…”

Stable isotope composition of the modern freshwater bivalve Corbicula fluminea

et al. 2009

Bivalve shells have been used in a number of paleoclimate and paleoenvironment studies. In order to investigate oxygen and carbon isotope fractionation between bivalve aragonite and host water, a one year monitoring experiment was conducted. Cooler temperatures seem to cause cessation of growth, suggesting that a threshold temperature may control the onset and cessation of growth. Shell δ 13 C are more negative than predicted δ 13 C values, and we observed that all the specimens showed a trend of lower δ 13 C values with increasing age, this suggests that the incorporation of metabolic carbon is the cause of the negative offset in shell δ 13 C. The variable offset from equilibrium δ 13 C values precludes the direct use of Corbicula fluminea shell in the study of the δ 13 C DIC in ancient bodies of water.

Oxygen isotope ratios (δ 18 O) of three Pacific oyster (Crassostrea gigas) specimens from the Neolithic Yeondae-do shell midden site, Tongyeong, Korea, were analyzed to determine the seasonality of shellfish gathering and site occupation. Oxygen isotope samples were taken from the left valve hinge sections of the specimens. Oxygen isotope values ranged between -0.1 ‰ and -2.4 ‰, between -0.2 ‰ and -2.9 ‰, and between 0.3 ‰ and -2.8 ‰ in oyster specimen #one, #two and #three, respectively. The isotope profiles showed seasonal temperature cycles, providing information related to the seasonality of shellfish gathering and site occupation. Hinge-edge oxygen isotope values of the specimens showed decreasing trends after passing through maximum values (winter), indicating that they formed during spring. Thus it can be assumed that during spring season, oysters were gathered and the site was occupied.
