NANAHAB -- Habitat polygons for the nearshore North Anacapa Island, Channel Islands NMS

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。研究人员整合了潜水员、遥控无人潜水器（ROV）与载人潜水器的视频样带测线数据、水深地形数据、沉积样品资料以及声呐测绘成果，以全面刻画生境的地质、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）联合海洋资助-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）与美国国家公园管理局（National Park Service, NPS）的科研人员开展合作项目，采集侧扫声呐与视频数据，最终生成该多边形覆盖数据集。该生境多边形数据集包含如下属性字段：大型生境（megahabitat）、底质固结度（bottom induration）、大型生境（macrohabitat，仅在具备对应实地观测数据时提供）、多边形面积、多边形周长以及水深。本生境地理信息系统（GIS）数据集展示了从海岸线至本次调查100米水深上限范围内的岩质性生境，此类生境可支撑石斑鱼属（Sebastes sp.）、鲍属（Haliotis sp.）及其他受胁底栖生物的栖息生存。
