  abstract = {{T}he use of the sclerochronology and geochemistry of a {N}ew {C}aledonian ({S}outh {W}est {P}acific) giant clam {H}ippopus hippopus shell as markers of environmental changes has been investigated. {G}rowth increment thickness and delta {O}-18 ratios were measured on 4 years of shell growth of a modern specimen. {D}uring the last year, this giant clam was placed in a tank equipped for high-frequency environmental monitoring. {B}ecause shell is secreted in isotopic equilibrium with the seawater, the palaeo-sea surface temperature ({SST}) equation obtained faithfully reproduces the seasonal {SST} amplitudes. {G}rowth increment thickness changes are seasonal and, for more than 50%, governed by the {SST} changes. {T}he transplantation from the in situ site to the tank and reproduction events reduces the strength of growth and {SST} relationships. {N}evertheless, growth increment thickness measurements can give information on average, minimal and maximal past {SST} in diagenetically altered shells. {A} peculiar growth event characterized by a short, drastic and significant decrease has been identified and attributed to an intense upwelling event. {T}his study further highlights the use of giant clam shell delta {O}-18 as a {SST} proxy but also demonstrates that {H}. hippopus growth increment thickness changes provide useful information on past environmental settings and on exceptional events, for example, intense upwellings.},
