Baited remote underwater video station (BRUVS) surveys of fish in the Hawaiian Archipelago from 2012-09-01 to 2014-09-27 (NCEI Accession 0169370)

Supported by the NOAA Coral Reef Ecosystem Program (CREP), the data provided in this data set — including fish species, lengths, counts, and benthic cover — were generated from the analysis of video footage from baited underwater video station (BRUVS) surveys conducted during NOAA Pacific Islands Fisheries Science Center (PIFSC) missions in the Main Hawaiian Islands in September 2012 and November 2013, and the Northwestern Hawaiian Islands in May and September 2014.

Each BRUVS uses high-definition video cameras mounted 0.7 m apart on a base bar that is inwardly converged at 8°, set up as a stereo-video system. The video images from the cameras are subsequently analyzed to identify fish species and length. The use of bait attracts a wide diversity of fish species into the field of view of the cameras, but CREP is also experimenting with unbaited deployments.

本数据集由美国国家海洋和大气管理局珊瑚礁生态系统项目（NOAA Coral Reef Ecosystem Program，简称CREP）支持，其中包含鱼类物种、长度、数量以及底栖覆盖度等信息。这些数据是通过分析2012年9月和2013年11月在夏威夷群岛主群岛及2014年5月和9月在夏威夷群岛西北部岛屿期间，美国国家海洋和大气管理局太平洋岛屿渔业科学中心（NOAA Pacific Islands Fisheries Science Center，简称PIFSC）任务中布设的诱饵水下视频站（Baited Underwater Video Station，简称BRUVS）调查的视频资料所得。BRUVS系统采用高清视频摄像头，摄像头之间相距0.7米，并安装在向内收敛的8°基座上，构成立体视频系统。随后对摄像头捕捉的视频图像进行分析，以识别鱼类物种及其长度。诱饵的使用吸引了多种鱼类进入摄像头的视野，但CREP也在尝试无诱饵部署的实验。
