Pacific Walrus Coastal Haulout Database 1852-2016

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.我们从已公开的研究报告、对沿海居民与航空观测者的访谈，以及作者的实地观测记录中，整理了现有关于太平洋海象（Pacific walrus）上岸聚集位点（haulout）的相关信息。本数据集以地理参考数据库的形式呈现，可通过标准地理信息系统与数据库管理软件进行查询与可视化展示。该数据库共收录150条太平洋海象上岸聚集位点记录，并附带基础特征摘要，涵盖最大聚集规模、年龄与性别组成、使用季节以及最近一次使用的年代。相关报告的引文信息以文献数据库的形式一并提供。
