SCR_Aerial_SantaCatalinaIsland_East_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 vector 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. These data ware originally provided to Oceanspaces (http://oceanspaces.org/) in 2013 as part of the South Coast baseline monitoring program. In 2022 this dataset was uploaded to the California Ocean Protection Council Data Repository (https://opc.dataone.org/) by Mike Esgro ([e-mail]) and Rani Gaddam ([e-mail]). 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）基线计划开发的，隶属于项目“基于历史与同步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）。本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年的巨藻（Kelp）专题图。本次分析所用的影像与分类数据，由海洋成像公司（Ocean Imaging）通过其自主研发的数字多光谱相机（Digital Multispectral Camera, DMSC）、Microsoft UltraCam-X航空相机系统采集，同时还获取了由加利福尼亚州鱼类与野生动物局（California Department of Fish and Wildlife, CDFW）归档的巨藻栖息地分类数据。关于该类设备与数据处理的详细说明，详见本文档的数据溯源（Lineage）章节。

持久性分析结果展示了南海岸区域与海洋保护区内巨藻床的存续情况，以分析年度占比进行量化。数据集覆盖范围为从加利福尼亚州康塞普申角（Point Conception, CA）向南至加利福尼亚州帝国海滩（Imperial Beach, CA）的海域。本GIS分析成果文件的交付格式包括GeoTIFF（.tif）、ESRI Shapefile以及Adobe Acrobat PDF格式。

本矢量数据集针对加利福尼亚州南海岸区域（SCR）内从康塞普申角至帝国海滩的巨型巨藻床开展了持久性分析。本次特定栅格分类数据涵盖了情人湾州立海洋保护区（State Marine Conservation Area, SMCA）与赌场角州立海洋保护区（SMCA）。本数据集最初于2013年作为南海岸基线监测计划的一部分，提交至Oceanspaces平台（http://oceanspaces.org/）。2022年，Mike Esgro（邮箱：[e-mail]）与Rani Gaddam（邮箱：[e-mail]）将本数据集上传至加利福尼亚州海洋保护委员会数据仓库（California Ocean Protection Council Data Repository, https://opc.dataone.org/）。加利福尼亚州长期海洋保护区边界与项目信息表可通过以下链接的独立数据集获取：https://opc.dataone.org/view/doi:10.25494/P64S3W。
