  abstract = {{W}e evaluate the use of oxygen isotope values of biogenic apatite for tracking freshwater to marine migration in modem and fossil {P}acific sockeye salmon. {O}xygen isotope analyses of otoliths, vertebrae, and teeth of three anadromous modem sockeye salmon from {A}laska establish a basis for the interpretation of fossil vertebrae and tooth apatite from {P}leistocene sockeye salmon of the {S}kokomish {R}iver {V}alley, {W}ashington. {H}igh resolution delta {O}-18 profiles in salmon otoliths provide, at a monthly resolution, a detailed record of individual history including continental rearing, migration to sea, seasonal variation in sea surface temperatures during marine life, and spawning migration before capture. {P}acific salmon teeth are constantly renewed with the last set of teeth forming under the influence of freshwater. {T}herefore, they do not allow inference concerning sea-run versus landlocked life history in fossil salmon. {S}almon vertebrae are also ambiguous indicators of life history regarding fresh versus marine water because centra are minimally ossified in the freshwater stages of life and the outermost layer of vertebral bone might be resorbed to provide nutrients during the non-feeding phase of the spawning migration. {T}herefore, delta {O}-18 values of accretionary growth rings in sea-run salmon vertebrae are dominated by the marine signal only if they are not diagenetically altered in freshwater deposits. {I}n {P}leistocene sockeye reported here, neither the teeth nor vertebral apatite present clear marine delta {O}-18 values due to the combined effects of tooth replacement and diagenetic alteration of bone and dentine. delta {O}-18({PO}4) values of fossil vertebrae are intermediate between delta {O}-18({PO}4) values of enamel and basal tooth dentin. {A}ssuming a similar rate of isotope exchange of vertebrae and dentine with freshwater during diagenesis, these results are interpreted to reflect formation of the teeth under the influence of freshwater, and formation of the vertebrae under the influence of oceanic water. {O}ur approach demonstrates that when appropriate knowledge of tissue formation is available, isotopic differences between altered and unaltered tissue holds promise of distinguishing between marine and freshwater origin of the tissues.
