    dct:description "We summarize available information on Pacific walrus haulouts from available reports, interviews with coastal residents and aviators, and personal observations of the authors.  We provide this in the form of a georeferenced database that may be queried and displayed with standard geographic information system and database management software.  The database contains 150 records of Pacific walrus haulouts, with a summary of basic characteristics on maximum haulout size, age-sex composition, season of use, and decade of most recent use.  Citations to reports are provided as a bibliographic database." ;
