Seafloor character--Offshore of Carpinteria, California

This part of SIM 3261 presents data for the seafloor-character map (see sheet 5, SIM 3261) of the Offshore of Carpinteria map area, California. The raster data file is included in "SeafloorCharacter_OffshoreCarpinteria.zip," which is accessible from http://pubs.usgs.gov/ds/781/OffshoreCarpinteria/data_catalog_OffshoreCarpinteria.html.
This raster-format seafloor-character map shows five substrate classes of Offshore of Carpinteria map area. The five substrate classes mapped in this area have been colored to indicate which of the following California Marine Life Protection Act depth zones and slope classes they belong: Depth Zone 2 (intertidal to 30 m), Depth Zone 3 (30 to 100 m), and Slope Class 1, 0 degrees to 5 degrees (flat). Depth Zone 1 (intertidal), Depth Zones 4 and 5 (greater than 100 m), and Slopes Classes 2 to 4, greater than 5 degrees (sloping to vertical) are not present in this map area. The map is created using a supervised classification method described by Cochrane (2008), available at http://doc.nprb.org/web/research/research%20pubs/615_habitat_mapping_workshop/Individual%20Chapters%20High-Res/Ch13%20Cochrane.pdf.

SIM 3261的本章节提供了加利福尼亚州卡平特里亚近海制图区的海底特征地图（seafloor-character map，详见SIM 3261第5幅图）的相关数据。栅格数据（raster data）文件包含于"SeafloorCharacter_OffshoreCarpinteria.zip"压缩包中，可通过http://pubs.usgs.gov/ds/781/OffshoreCarpinteria/data_catalog_OffshoreCarpinteria.html获取。

该栅格格式海底特征地图展示了卡平特里亚近海制图区的5类底质类型。本区域内绘制的5类底质已通过配色标注其所属的《加州海洋生物保护法》（California Marine Life Protection Act）划定的深度带与坡度等级：深度带2（潮间带至30米）、深度带3（30米至100米），以及坡度等级1（0°至5°，平缓地形）。本制图区未涵盖深度带1（潮间带）、深度带4与5（水深大于100米），以及坡度等级2至4（坡度大于5°，涵盖缓坡至垂直崖壁）的区域。本地图采用Cochrane（2008）所述的监督分类（supervised classification）方法制作，相关文献可通过http://doc.nprb.org/web/research/research%20pubs/615_habitat_mapping_workshop/Individual%20Chapters%20High-Res/Ch13%20Cochrane.pdf查阅。
