SCR_Aerial_SantaCatalinaIslandEast_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 Lover's Cove SMCA and Casino 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岸海洋资助计划（Sea Grant）南海岸海洋保护区基线项目开发，作为“利用历史与同期多光谱影像开展近岸底质制图与变化分析”项目（项目编号：#R/MPA 30 10-049）的组成部分。研究区域为南海岸区域（South Coast Region, SCR）。本次数据集采用了1999年至2012年的巨藻专题图。海洋成像公司（Ocean Imaging）从自有数字多光谱相机（DMSC）、微软UltraCam-X航空相机系统获取本次分析所用的影像与分类数据，同时获取了由加利福尼亚州鱼类与野生动物局（CDFW）归档的巨藻栖息地分类数据。关于该类设备与数据处理流程的详细说明，请参见本文档的数据溯源（Lineage）章节。持久性分析结果以分析年度占比的形式，展示了南海岸区域（SCR）及海洋保护区内巨藻床的存续情况。本次交付的GIS分析成果文件覆盖范围北至加利福尼亚州孔塞普申角，南至加利福尼亚州帝国海滩，文件格式包括GeoTIFF（.tif）、ESRI Shapefile以及Adobe Acrobat PDF格式。本栅格数据集针对加利福尼亚州南海岸区域（SCR）的巨藻床开展持久性分析，分析范围同样北至孔塞普申角、南至帝国海滩。本次特定栅格分类覆盖了情人湾州立海洋保护区（Lover's Cove SMCA）与赌场角州立海洋保护区（Casino Point SMCA）。本数据集最初于2013年作为南海岸基线监测项目的组成部分，上传至海洋空间平台（Oceanspaces, 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，由迈克·埃斯格罗（[e-mail]）与拉尼·加达姆（[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/），同期新增了GIS分析成果。加利福尼亚州长期海洋保护区边界与项目信息表格可通过以下链接的独立数据集获取：https://opc.dataone.org/view/doi:10.25494/P64S3W。
