资源简介:
Substrate was classified using the method of (Cochrane and Lafferty, 2002) for this study. Sea floor character derived from towed sidescan sonar data is available for the mainland coast within the study area from USGS online publications (Cochrane and others, 2003; Cochrane and others, 2005). The number of substrate classes was reduced because rugosity could not be derived for all areas due to the lack of bathymetry data for other data sets used in the study.

本研究采用Cochrane与Lafferty(2002)提出的方法开展底质分类。研究区内大陆海岸的海底特征可通过美国地质调查局(U.S. Geological Survey, USGS)在线公开文献获取,该特征基于拖曳式侧扫声呐(towed sidescan sonar)数据解译得到(Cochrane等,2003;Cochrane等,2005)。由于本研究所用的其他数据集缺乏水深数据(bathymetry data),无法在全部研究区域提取粗糙度(rugosity)信息,因此缩减了底质分类的类别数量。
