SCR_Aerial_SantaCatalinaIslandNorth_1999_2012_KelpPersistence

These raster and vector datasets were developed for the Sea Grant South Coast MPA Baseline Program as part of the project “Nearshore Substrate Mapping and Change Analysis using Historical and Concurrent Multispectral Imagery” (#R/MPA 30 10-049). The study region is the South Coast Region (SCR). Kelp thematic maps from 1999-2012 were used for this product. Ocean Imaging acquired the imagery and classification data used for this analysis from its own Digital Multispectral Camera (DMSC), the Microsoft UltraCam-X aerial camera system and from kelp habitat classifications archived by the California Department of Fish and Wildlife (CDFW). Details on this systems and the data processing are below in the Lineage section of this document. The persistence analyses show the persistence of kelp beds in the SCR and MPAs as a percentage of the number of years analyzed. The coverage area is from Conception, CA south to Imperial Beach, CA. The GIS analysis product files are deliverd are in GeoTIFF (.tif) and ESRI Shapefile formats as well as Adobe Acrobat PDF files. This raster dataset contains a persistence analysis of giant kelp beds along the California South Coast Region (SCR) from from Point Conception, CA down to Imperial beach, CA. This specific raster classification includes the Long Point SMR, Blue Cavern SMCA, Arrow Point to Lion Head Point SMCA. This dataset was originally uploaded to Oceanspaces (http://oceanspaces.org/) and the Knowledge Network for Biocomplexity (KNB, https://knb.ecoinformatics.org/data) in 2013 as part of the South Coast baseline monitoring program. In 2022 this dataset was moved to the California Ocean Protection Council Data Repository (https://opc.dataone.org/) by Mike Esgro ([e-mail]) and Rani Gaddam ([e-mail]). At that time the GIS analysis products were added to the dataset. The long-term California MPA boundary and project info tables can be found as a separate dataset here: https://opc.dataone.org/view/doi:10.25494/P64S3W.本栅格与矢量数据集是为海洋资助计划（Sea Grant）南海岸海洋保护区（Marine Protected Area, MPA）基线项目开发，作为“基于历史与同期多光谱影像的近岸底质制图与变化分析”项目（编号#R/MPA 30 10-049）的组成部分。本研究的区域为南海岸区域（South Coast Region, SCR）。本数据集采用了1999年至2012年的大型褐藻（Kelp）专题图件。 影像与分类数据由Ocean Imaging公司通过其自研的数字多光谱相机（Digital Multispectral Camera, DMSC）、微软UltraCam-X航空相机系统获取，同时还采用了加利福尼亚州鱼类与野生动物局（California Department of Fish and Wildlife, CDFW）归档的褐藻生境分类数据。关于该系统与数据处理的详细说明，请参见本文档的“数据谱系（Lineage）”章节。 本持续性分析以研究年数占比为指标，展示了南海岸区域及海洋保护区内大型褐藻床的存续情况。数据覆盖范围为从加利福尼亚州孔塞普申角（Point Conception, CA）向南至帝国海滩（Imperial Beach, CA）的海域。 本GIS分析成果文件的格式包括GeoTIFF（.tif）栅格格式、ESRI Shapefile矢量格式，以及Adobe Acrobat可移植文档格式（PDF）文件。本栅格数据集包含加利福尼亚州南海岸区域（SCR）内，从孔塞普申角至帝国海滩沿线的巨型褐藻床持续性分析结果。本次栅格分类覆盖的区域包括长点州立海洋保护区（Long Point State Marine Reserve, SMR）、蓝洞州立海洋保护区域（Blue Cavern State Marine Conservation Area, SMCA）以及箭头角至狮头角州立海洋保护区域（Arrow Point to Lion Head Point SMCA）。 本数据集最初于2013年作为南海岸基线监测项目的一部分，上传至Oceanspaces平台（http://oceanspaces.org/）与生物复杂性知识网络（Knowledge Network for Biocomplexity, KNB, https://knb.ecoinformatics.org/data）。2022年，Mike Esgro（邮箱：[e-mail]）与Rani Gaddam（邮箱：[e-mail]）将本数据集迁移至加利福尼亚州海洋保护委员会数据仓储平台（https://opc.dataone.org/），并于同期将GIS分析成果补充至本数据集内。加州长期海洋保护区边界与项目信息表格可通过以下链接获取独立数据集：https://opc.dataone.org/view/doi:10.25494/P64S3W。
