NANPHAB -- Benthic Habitat polygons for North 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.

已针对圣巴巴拉盆地周边的海洋保护区点位，构建了底栖生境多边形覆盖数据集。本数据集整合了潜水调查、遥控无人潜水器（Remotely Operated Vehicle，ROV）及载人潜水器的视频样带数据、水深地形数据、沉积样品与声呐测绘成果，以刻画生境的地质、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）联合海格兰特-MERRP、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）与国家公园管理局（National Park Service，NPS）的研究人员，通过协作项目采集了侧扫声呐与视频数据，进而生成了该多边形覆盖数据集。该生境多边形具备以下属性字段：大生境类型、底质固结程度、宏生境（仅当宏生境观测数据可用时填充）、多边形面积、多边形周长与水深。本生境地理信息系统（GIS）数据集展示了从岸线延伸至本次调查100米水深限值范围内的岩质生境，该生境适宜平鲉属（Sebastes sp.）鱼类、鲍属（Haliotis sp.）鲍鱼及其他受威胁底栖物种栖息。
