Published by Pacific Islands Fisheries Science Center | National Oceanic and Atmospheric Administration, Department of Commerce | Metadata Last Checked: December 19, 2025 | Last Modified: 1981-01-01T00:00:00.000+00:00
This data set contains records of all individually identified Hawaiian monk seals since 1981. These seals were identified by PSD personnel and cooperating scientists as part of the ongoing monk seal population assessment efforts. In addition, this data set contains records for all seals tagged by USFWS in earlier years and still present in the population when the current research effort began, and also contains some miscellaneous earlier records extending back as far as 1962. MasterID data are contained in two record types, the "Seal" record containing information that doesn't change over the seal's lifetime (ex., sex, birth date and location, mother, death date) and the "Annual" record containing information that changes annually (ex., size, pupping and molting information, location that year, and applied bleach marks).
