“…Cold cathode (Cathodyne-OPEA, 15-20 kV and 200-300 lA mm -2 under a pressure of 0.05 Torr) observations were made on the foliated calcite of the hinge section (see Fig. 3), because this area contains an ontogenetic record of both the oysters' hinge growth and the environmental conditions experienced throughout their life (Stenzel 1963;Carriker and Palmer 1979;Richardson et al 1993;Kirby et al 1998). Following the methodologies of Langlet et al (2006) and Lartaud et al (2006), CLintensity variations across the hinge sections were analyzed using the software Image J-1.33 (http://rsbweb.nih.gov/ij/) to determine microscopic changes in CL that would reveal the patterns of incremental growth lines in the hinges of the oyster shells.…”

Cathodoluminescence (CL) microscopy of the foliated calcite shell hinge sections of live-collected oyster Crassostrea gigas collected at seven locations along a latitudinal gradient from the Netherlands in the North Sea to the Atlantic coast of France, revealed variations in luminescence that were attributable to seasonal variations in calcification of the hinge. Photomicrographs of hinge sections and luminescence profiles were analyzed to define a micro-sampling strategy that was adopted to drill the hinge samples to determine their isotopic composition. Reconstructed seasonal seawater temperatures determined from the stable oxygen isotope (d 18 O) composition along growth profiles from 32 oyster shell hinges showed distinct seasonal isotopic cycles that were compared with in situ measured seawater temperatures and salinities at each location. Comparison of the amplitude of the (d 18 O) signal and the annual maximum and minimum seawater temperatures demonstrated that C. gigas shells from several locations provided a reliable record of seasonal seawater temperature variation. The exception to this was oysters from the Netherlands and northern France where winter growth rates at low temperatures were slow so that insufficient shell was deposited to allow adequate spatial resolution of sampling and this resulted in time-averaging of the reconstructed seawater temperatures and an overestimation of winter seawater temperature. A potential variability in d 18 O w -salinity relationship at low salinities could also explain the high difference between measured and predicted seawater temperatures in Dutch areas. The finding that latitudinal differences in oyster hinge growth rates and/or changes in the d 18 O w -salinity relationship can result in bias of the seawater temperature deduced from the stable isotopic composition of the hinge should be taken into account when reconstructing latitudinal gradients in seawater temperature.

“…Although direct observations of the life span of wild oysters are scarce, modern Ostrea edulis and Crassostrea gigas have been known to live for more than 25 years (Stenzel 1971;Emmett et al 1991;Richardson et al 1993). Moreover, counting of presumed annual layers in the ligamental area of a Sr/ 86 Sr of freshwater ( Table 6) that entered the Lorca Basin during secretion of oyster shells #x1-1, 1a-1, 1a-2, 4-1, and 4-2.…”

We use d 18 O and d 13 C of oyster shells, inferred seawater d 18 O (d w ), and temperature tolerance ranges of modern zooxanthellate coral communities to constrain and model paleo-salinities of marginal-marine waters of the Miocene Lorca Basin, Spain. Salinities ranged from 22 to 32 PSU during growth of coral bioherms and carpets of the Soriana and Parrilla formations, and from 35 to 39 PSU during deposition of the Hondo Formation reef complex. The periods with lower modeled salinities correspond with deltaic and alluvial-fan sedimentation in the area. The modeling is supported by 87 Sr/ 86 Sr data and provides new insights into the evolution of the local depositional settings. Departures of Sr-isotope values from the global oceanic curve occur within the intervals with the lowest modeled salinities, and the non-oceanic 87 Sr/ 86 Sr preserved in individual oyster shells was probably sourced from uplifted Aquitanian-Burdigalian limestones. 87 Sr/ 86 Sr values that plot along the global ocean Sr-isotope curve for the late Miocene indicate a Tortonian age for the upper part of the Soriana Formation and the Parrilla Formation, and a Messinian age for the Hondo Formation. More generally, we demonstrate how the chemical analyses of oyster shells provide additional information regarding short-term oscillations of salinity and temperature of seawater beyond what can be obtained by traditional paleoecological methods.

“…Acetate peels of the sectioned umbo region of twelve oyster shells collected in April and May 1993 from natural populations, which had settled intertidally on the ground in the River Teign, Menai Strait and from oysters, hatchery-reared in 1989 and grown in trays in the Menai Strait, were prepared by the method of Richardson et al (1993b). Annual growth lines were examined and counted using a low power microscope.…”
