SCR_Aerial_SantaRosaIslandNorth_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 Carrington Point SMR, and Skunk Point SMR. 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）基线计划开发，作为"利用历史与同期多光谱影像开展近岸底质制图及变化分析"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）。本数据集采用了1999年至2012年的海带专题图。

海洋成像公司（Ocean Imaging）所用的影像与分类数据来源于自研的数字多光谱相机（Digital Multispectral Camera, DMSC）、微软UltraCam-X航空相机系统，以及加州鱼类与野生动物局（California Department of Fish and Wildlife, CDFW）归档的海带生境分类数据。关于该系统与数据处理的详细说明，请参见本文档的"谱系（Lineage）"章节。

持久性分析结果以分析年份占比的形式，展示了南海岸区域及各海洋保护区内海带床的留存情况。数据覆盖范围为从加州孔塞普申角向南至帝国海滩的海域。本地理信息系统（GIS）分析成果文件采用GeoTIFF（.tif）、ESRI Shapefile以及Adobe Acrobat PDF格式存储。

本栅格数据集针对加州南海岸区域（SCR）内从孔塞普申角至帝国海滩的巨型海带床开展了持久性分析。本次栅格分类范围涵盖卡林顿点州立海洋保护区（Carrington Point SMR）与斯坎克点州立海洋保护区（Skunk Point SMR）。

本数据集最初于2013年作为南海岸基线监测计划的组成部分，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，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州海洋保护委员会数据仓储库（California Ocean Protection Council Data Repository, https://opc.dataone.org/），并于同期将GIS分析成果补充至本数据集内。
