The data set first provides specimen identification information: Specimen ID, estimated age, and AFSC RACE cruise number. Second, the data describes the milling and physical properties of each milled sampled, up to 42 samples per specimens: volume and mass. Finally, the data contain information and results from mass spectrometry analysis measuring d13C and d18O. The purpose of this data set is to use stable to confirm the accuracy of Pacific cod ages estimated from otolith growthzones. The funding source for this study is the North Pacific Research Board. The samples used in this study were collected by the Research Assessment and Conservation Engineering Division (RACE) on survey cruises. underDevelopment Kastelle, Craig craig.kastelle@noaa.gov pointOfContact Kastelle, Craig craig.kastelle@noaa.gov custodian notPlanned Non-Federal Funding theme PARR Exclusion Stable 18 O age validation annual seasonal temperature cycles break-and-burn age fish age determination high-resolution microsampling mass spectrometry micromilling otolith theme Alaska Bering Sea place DOC/NOAA/NMFS/AFSC > Alaska Fisheries Science Center, National Marine Fisheries Service, NOAA, U.S. Department of Commerce dataCentre Global Change Master Directory (GCMD) Data Center Keywords 2017-04-24 publication 8.5 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2025.

Completeness Report AFSC RACE surveys may not contain a representation of the smallest juvenile Pacific cod, because they are not able to sample the very near-shore areas. Also, by careful design, our study did not use specimens that were aged 6 years or older in the original age reading (final age) Conceptual Consistency Data from RACE is proofed by normal protocols routinely used on survey data. Data generated by the Age and Growth program (age estimates and associated codes) is proofed for typing errors, tested for precision with a 20% replicate.
