SANPHAB -- Habitat polygons for South Anacapa Passage (UTM 10N, NAD83)

Benthic habitat polygon coverages have been created for marine reserve locations surrounding the Santa Barbara Basin. Diver, ROV and submersible video transects, bathymetry data, sedimentary samples, and sonar mapping, have been integrated to describe the geological, biological, and oceanographic aspects of habitat. Anacapa Reserve, is part of the Marine Ecological Reserves Research Program (MERRP). The U.S. Geological Survey (USGS), in a cooperative project with Sea Grant-MERRP and investigators at National Marine Fisheries Service (NMFS), the Channel Islands National Marine Sanctuary (CINMS), and National Park Service (NPS) has collected sidescan sonar and video data to produce a polygon coverage. The habitat polygons have attributes for megahabitat, bottom induration, macrohabitat (where macrohabitat observations are available), polygon area, polygon perimeter, and water depth. The habitat GIS shows rocky habitat suitable for rockfish (Sebastes sp.), abalone (Haliotis sp.), and other threatened benthic species from the shoreline out to the 100-m depth limit of the survey.

针对圣巴巴拉盆地周边的海洋保护区点位，已生成底栖生境（benthic habitat）多边形覆盖数据集。研究整合了潜水员、遥控无人潜水器（Remotely Operated Vehicle, ROV）与载人潜水器的视频样带测线数据、水深地形数据、沉积物样品资料以及声呐测绘成果，用以描述生境的地质、生物与海洋学特征。阿纳卡帕保护区（Anacapa Reserve）隶属于海洋生态保护区研究计划（Marine Ecological Reserves Research Program, MERRP）。美国地质调查局（U.S. Geological Survey, USGS）联合海赠-海洋生态保护区研究计划（Sea Grant-MERRP）、美国国家海洋渔业局（National Marine Fisheries Service, NMFS）、海峡群岛国家海洋保护区（Channel Islands National Marine Sanctuary, CINMS）以及美国国家公园管理局（National Park Service, NPS）的科研人员，通过采集侧扫声呐与视频数据，生成了本多边形覆盖数据集。该底栖生境多边形数据集包含以下属性字段：巨型生境、底质固结度、大型生境（仅在具备大型生境观测数据时提供）、多边形面积、多边形周长以及水深。这套生境地理信息系统（Geographic Information System, GIS）数据集展示了从岸线延伸至本次调查100米水深阈值范围内，适合岩鱼属（Sebastes sp.）、鲍属（Haliotis sp.）及其他受胁底栖物种栖息的岩质生境。
