Sampling of individual growth increments of two specimens of the bivalve Camptochlamys alaskensis provides a high-resolution record of shell stable isotope composition. The heavy carbon isotopic values of the specimens support a late Paleocene age for the youngest marine beds of the Prince Creek Formation exposed near Ocean Point, Alaska. The oxygen isotopic composition of regional freshwater runoff is estimated from the mean ´18O value of two freshwater bivalves collected from approximately coeval fluviatile beds. Over a 30  340 range of salinity, values assumed to represent the tolerance of C. alaskensis, the mean annual shallow-marine temperature recorded by these individuals is between 11° and 22°C. These values could represent maximum estimates of the mean annual temperature because of a possible warm-month bias imposed on the average ´18O value by slowing or cessation of growth in winter months. The amplitude of the molluscan ´18O time series probably records most of the seasonality in shallow-marine temperature. The annual temperature range indicated is approximately 6°C, suggesting very moderate high-latitude marine temperature seasonality during the late Paleocene. On the basis of analogy with modern Chlamys species, C. alaskensis probably inhabited water depths of 3050 m. The seasonal temperature range derived from ´18O is therefore likely to be damped relative to the full range of annual sea surface temperatures. High-resolution sampling of molluscan shell material across inferred growth bands represents an important proxy record of seasonality of marine and freshwater conditions applicable at any latitude. If applied to other regions and time periods, the approach used here would contribute substantially to the paleoclimate record of seasonality.","pubRank":"1"}],"site":[{"NOAASiteId":"57159","siteName":"Ocean Point","siteCode":null,"mappable":"Y","locationName":"Continent>North America>United States Of America>Alaska","geo":{"geoType":"Feature","geometry":{"type":"POINT","coordinates":["70.0833","-151.3667"]},"properties":{"southernmostLatitude":"70.0833","northernmostLatitude":"70.0833","westernmostLongitude":"-151.3667","easternmostLongitude":"-151.3667","minElevationMeters":null,"maxElevationMeters":null}},"paleoData":[{"dataTableName":"Bice1996","NOAADataTableId":"33088","earliestYear":65000000,"mostRecentYear":62000000,"timeUnit":"cal yr BP","earliestYearBP":65000000,"mostRecentYearBP":62000000,"earliestYearCE":-64998050,"mostRecentYearCE":-61998050,"coreLengthMeters":null,"dataTableNotes":null,"species":[],"dataFile":[{"fileUrl":"https://www.ncei.noaa.gov/pub/data/paleo/contributions_by_author/bice1996/bice1996.txt","urlDescription":"Original Data and Full Metadata","linkText":"bice1996.txt","variables":[{"cvDataType":"PALEOCEANOGRAPHY","cvWhat":"sampling metadata>sample identification","cvMaterial":null,"cvError":null,"cvUnit":null,"cvSeasonality":null,"cvDetail":null,"cvMethod":null,"cvAdditionalInfo":null,"cvFormat":"Character","cvShortName":null},{"cvDataType":"PALEOCEANOGRAPHY","cvWhat":"chemical composition>isotope>isotope ratio>delta 18O","cvMaterial":"biological material>organism>bivalve","cvError":null,"cvUnit":"concentration unit>parts per notation unit>parts per thousand>per mil>per mil PDB","cvSeasonality":null,"cvDetail":null,"cvMethod":null,"cvAdditionalInfo":null,"cvFormat":"Numeric","cvShortName":null},{"cvDataType":"PALEOCEANOGRAPHY","cvWhat":"chemical composition>isotope>isotope ratio>delta 13C","cvMaterial":"biological material>organism>bivalve","cvError":null,"cvUnit":"concentration unit>parts per notation unit>parts per thousand>per mil>per mil PDB","cvSeasonality":null,"cvDetail":null,"cvMethod":null,"cvAdditionalInfo":null,"cvFormat":"Numeric","cvShortName":null},{"cvDataType":"PALEOCEANOGRAPHY","cvWhat":"chemical composition>isotope>isotope ratio>delta 18O","cvMaterial":"biological material>organism>bivalve","cvError":null,"cvUnit":"concentration unit>parts per notation unit>parts per thousand>per mil>per mil PDB","cvSeasonality":null,"cvDetail":null,"cvMethod":null,"cvAdditionalInfo":"replicate","cvFormat":"Numeric","cvShortName":null},{"cvDataType":"PALEOCEANOGRAPHY","cvWhat":"chemical composition>isotope>isotope ratio>delta 13C","cvMaterial":"biological material>organism>bivalve","cvError":null,"cvUnit":"concentration unit>parts per notation unit>parts per thousand>per mil>per mil PDB","cvSeasonality":null,"cvDetail":null,"cvMethod":null,"cvAdditionalInfo":"replicate","cvFormat":"Numeric","cvShortName":null}],"NOAAKeywords":["earth science>paleoclimate>paleocean>carbon isotopes","earth science>paleoclimate>paleocean>oxygen isotopes"]}]}]}],"reference":{"pastThesaurusSkos":"https://www.ncei.noaa.gov/access/paleo-search/skos/past-thesaurus.rdf","pastThesaurusExplorer":"https://www.ncei.noaa.gov/access/paleo-search/cvterms","gcmdKeywordThesaurus":"https://earthdata.nasa.gov/earth-observation-data/find-data/idn/gcmd-keywords"},"dataLicenseDescription":null,"dataLicenseUrl":null}
