Marine Arctic polygon distribution of Sockeye Salmon (Oncorhynchus nerka) (Walbaum, 1792)

Region(s) of distribution of Sockeye Salmon (Oncorhynchus nerka) (Walbaum, 1792) in the Arctic as digitized for U.S. Geological Survey Scientific Investigations Report 2016-5038. For details on the project and purpose, see the report at https://doi.org/10.3133/sir20165038. Complete metadata for the collection of species datasets is in the metadata document "Dataset_for_Alaska_Marine_Fish_Ecology_Catalog.xml" at https://doi.org/10.5066/F7M61HD7. Source(s) for this digitized data layer are listed in the metadata Process Steps section. Note that the original source may show an extended area; some datasets were limited to the published map boundary. Distributions of marine fishes are shown in adjacent Arctic seas where reliable data are available. The data were clipped to show only the marine distribution areas although some species also may have an inland presence.

本数据集为美国地质调查局（U.S. Geological Survey）《2016-5038号科学调查报告》（Scientific Investigations Report 2016-5038）数字化处理的红大马哈鱼（Sockeye Salmon，*Oncorhynchus nerka*，Walbaum, 1792）在北极区域的分布范围数据。有关本项目的细节与研究目的，请参阅DOI为https://doi.org/10.3133/sir20165038的官方报告。本次物种数据集合集的完整元数据收录于元数据文档"Dataset_for_Alaska_Marine_Fish_Ecology_Catalog.xml"，对应DOI为https://doi.org/10.5066/F7M61HD7。本数字化数据图层的数据源详见元数据文档的"处理步骤（Process Steps）"章节。需注意，原始数据源可能标注了更广的分布范围，部分数据集被限定于已发表的地图边界内。在具备可靠数据支撑的相邻北极海域，均标注了海洋鱼类的分布范围。尽管部分物种可能存在内陆栖息记录，但本数据集仅裁剪展示了其海洋分布区域。
