“…The term sclerochronology was first applied to a radiographic study on corals by Buddemier et al (1974, p. 196) and more formally by Hudson et al (1976) Many authors differentiate sclerochronological studies and geochemical studies, for example, Williams et al (1982) state that they used "coordinated isotopic and sclerochronological (growth increment) studies" and Schöne et al (2007) entitled their paper "Combined sclerochronologic and oxygen isotope analysis of gastropod shells…". Therefore, in line with the differentiation already used by dendrochronologists to separate studies of tree ring width increments (dendrochronology) from isotopic or chemical analyses across rings (dendrochemistry) (e.g., Smith and Shortle 1996;Verheyden et al 2005;Poussart et al 2006), we propose to use sclerochronology for studies of the physical structure of the hard tissues of organisms, even when combined with geochemistry (e.g., growth line periodicity) and that sclerochemistry, as a sub-discipline of sclerochronology, be used to describe solely geochemical (isotopic or elemental) studies of the hard tissues of organisms.…”

Mg/Ca, Sr/Ca and Ba/Ca), which illustrate the usefulness and difficulties associated with using these proxies. Studies on fossil mollusc shells are also provided, with one study that usesPliocene scallop shells to understand past ocean circulation and another that addresses the problem of diagenesis. Finally, a sclerochronological study of crystal prism width across the shell is presented. This issue demonstrates that many elemental and isotopic proxies contained in mollusc shells are complex. In spite of these complexities, environmental and climatic conditions can be extracted from them for use in palaeoclimatic and palaeoenvironmental research.

“…Scleractinian corals deposit a calcium carbonate skeleton (aragonite) in distinct, annual bands and can grow for several hundred yr. X-radiographic analysis of a thin slab of coral skeleton typically reveals alternating light and dark bands, each pair of which represents 1 yr of coral growth (e.g., Weber et al 1975;Hudson et al 1976;Barnes and Lough 1993). Corals incorporate the dissolved inorganic carbon (DIC) of the surrounding seawater as aragonite, a crystalline form of calcium carbonate, into their exoskeleton.…”

ABSTRACT. Coral skeletal radiocarbon records reflect seawater D 14 C and are useful for reconstructing the history of water mass movement and ventilation in the tropical oceans. Here, we reconstructed the inter-annual variability in central equatorial Pacific surface water D 14 C from 1922-1956 using near-monthly 14 C measurements in a Porites sp. coral skeleton (FI5A) from the windward side of Fanning Island (3°54¢32²N, 159°18¢88²W). The most pronounced feature in this record is a large, positive shift in the D 14 C between 1947 and 1956 that coincides with the switch of the Pacific Decadal Oscillation (PDO) from a positive to a negative phase in the mid-1940s. Although the absolute D 14 C values from 1950-1955 in FI5A differ from the D 14 C values of another coral core collected from the opposite side of the island, both records show a large, positive shift in their D 14 C records at that time. The relative increase in the D 14 C of each record is consistent with the premise that a common mechanism is controlling the D 14 C records within each coral record. Overall, the Fanning D 14 C data support the notion that a significant amount of subtropical seawater is arriving at the Equator, but does not allow us to determine the mechanism for its transport.

“…As regards sclerochronology, the term was first applied to a radiographic study on coral skeletons by Buddemeier et al (1974) and Hudson et al (1976), and its meaning has been recently reviewed by Grö cke and Gillikin (2008). The technique can be applied to mollusk shells (postmortem examination) and allows the historical reconstruction of shell-layer thickness changes, i.e., growth rate, in the temporal context in which the shell layers formed.…”

The life history of 15 giant clams, Hippopus hippopus, was studied in situ in the southern lagoon of New Caledonia; growth rate and animal behavior were studied both by sclerochronology and high-frequency noninvasive (HFNI) valvometry. Electrodes glued on each valve of each specimen recorded the shell-gaping behavior at 0.6-Hz frequency. A nonparametric regression model was used to model clam behavior. The daily increment thickness in the inner layer of five representative clams was measured. H. hippopus has its valves open during the day and partly closed during the night all year round, and shell growth is continuous. The cumulative growth using both techniques was similar, as was the mean daily thickness increment. The occurrence of one increment per day in H. hippopus shell was measured by valvometry. The five sclerochronological profiles were highly similar. Shell growth was significantly correlated to rising sea surface temperature (SST), up to 27uC. At the solar maximum, gaping behavior and increment thickness became erratic. SST-and solar irradiance-related stress could be related to physiological oxidative stress triggered by zooxanthellae symbionts. In the present context of globally increasing SST, our data indicate that the giant clams H. hippopus could live beyond their thermal comfort limits in summer in New Caledonia.
