Seafloor character, 2 m resolution--Monterey Canyon and Vicinity, California

This part of DS 781 presents the seafloor-character map of Monterey Canyon and Vicinity, California. The raster data file is included in "SeafloorCharacter_2m_MontereyCanyon.zip," which is accessible from http://dx.doi.org/10.5066/F7XD0ZQ4.
This raster-format seafloor character map shows five substrate classes in Monterey Canyon and Vicinity, California. The substrate classes mapped in this area have been further divided into the following California Marine Life Protection Act depth zones and slope classes: Depth Zone 2 (intertidal to 30 m), Depth Zone 3 (30 to 100 m), Depth Zone 4 (100 to 200 m), Slope Class 1 (0 degrees - 5 degrees), and Slope Class 2 (5 degrees - 30 degrees). Depth Zone 1 (intertidal), Depth Zone 5 (greater than 200 m), and Slopes Classes 3-4 (greater than 30 degrees) are not present in the region covered by this block. The map is created using a supervised classification method described by Cochrane (2008), using multibeam echosounder (MBES) bathymetry and backscatter data collected and processed between 1998 and 2014.

DS 781的本章节展示了加利福尼亚州蒙特雷峡谷及其周边区域的海底特征图。栅格数据文件包含于"SeafloorCharacter_2m_MontereyCanyon.zip"压缩包中，可通过http://dx.doi.org/10.5066/F7XD0ZQ4获取。

该栅格格式海底特征图涵盖了加利福尼亚州蒙特雷峡谷及其周边区域的5种基底类型。本区域绘制的基底类型进一步划分为《加州海洋生物保护法（California Marine Life Protection Act）》规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）、深度带4（100米至200米）、坡度等级1（0°~5°）以及坡度等级2（5°~30°）。深度带1（潮间带）、深度带5（200米以上）以及坡度等级3~4（坡度大于30°）未在本图幅覆盖范围内出现。本图采用Cochrane（2008）提出的监督分类方法制作，所用数据为1998年至2014年间采集并处理的多波束测深声呐（multibeam echosounder, MBES）水深与反向散射数据。
