North Central Coast: ROV surveys of soft and rocky deep-water ecosystems

This package includes data collected during ROV transects conducted within and adjacent to California's North Central Coast MPAs which were designated in accordance with the Marine Life Protection Act. The transects were conducted by the Institute of Applied Marine Ecology (IfAME) and Marine Applied Research and Exploration (MARE) aboard F/V Donna Kathleen during the summers of 2010 and 2011. These surveys were designed to collect baseline data, capturing the state of the NCC MPAs at the time of designation, to be used as a basis for future comparisons. The areas surveyed comprise deep benthic soft-bottom and rocky-reef ecosystems within a depth range of 20 m to 116 m. The ROV, Beagle, was equipped with forward and down facing video cameras as well as a downward facing still camera. Video and still imagery were collected for post-processing which included the extraction of ecological data including the number and size of fish and invert species along with habitat classification.This dataset was originally uploaded to Oceanspaces (http://oceanspaces.org/) in 2013 as part of the North Central Coast baseline monitoring program. In 2020 the baseline data and reports were uploaded to the California Ocean Protection Council Data Repository by Mike Esgro ([e-mail]) and Rani Gaddam ([e-mail]). Every attempt has been made to include all of the original data, metadata, and reports submitted in 2013, but please contact the Data Set Contacts with any questions. The long-term California MPA boundary and project info tables referenced in this dataset can be found as a separate dataset here: https://opc.dataone.org/view/doi:10.25494/P64S3W

本数据包收录了依照《海洋生物保护法》（Marine Life Protection Act）划定的加利福尼亚州中北部海岸海洋保护区（Marine Protected Areas, MPAs）及其毗邻海域内开展的遥控无人潜水器（Remotely Operated Vehicle, ROV）断面调查所采集的数据。该调查由应用海洋生态学研究所（Institute of Applied Marine Ecology, IfAME）与海洋应用研究与勘探中心（Marine Applied Research and Exploration, MARE）于2010年及2011年夏季搭乘渔船F/V Donna Kathleen完成。本次调查旨在收集基线数据，记录该批次海洋保护区获批时的生态现状，作为后续对比研究的基准。调查区域覆盖深度范围20米至116米的深海底质软底与岩礁生态系统。所用ROV“比格尔号（Beagle）”配备了前视、下视摄像机及下视静态相机。采集的视频与静态影像将用于后期处理，从中提取鱼类与无脊椎动物物种的数量、体型及栖息地分类等生态数据。该数据集最初于2013年作为中北部海岸基线监测计划的一部分上传至Oceanspaces平台（http://oceanspaces.org/）。2020年，Mike Esgro（[e-mail]）与Rani Gaddam（[e-mail]）将该基线数据及相关报告上传至加利福尼亚海洋保护委员会数据仓库。本次发布已尽可能完整收录2013年提交的全部原始数据、元数据与报告，如有疑问，请联系数据集联系人。本数据集引用的加利福尼亚州长期海洋保护区边界及项目信息表格，可通过以下独立数据集获取：https://opc.dataone.org/view/doi:10.25494/P64S3W
