Nearshore marine fish diversity in southern California using trawl information from the Southern California Coastal Water Research Project.

This is a point file of mean fish diversity within 5 minute grid cells. The Shannon Index of diversity was calculated from Southern California Coastal Water Research Project (SCCWRP) fish trawl data. Data from 425 fishery independent trawls ranging from 2-215 meters depth were collected in 1994 and 1998 during the months of June-August. Using ArcGIS, 5 x 5 minute grids were created and mean...

本数据集为一组均值鱼类多样性点文件，其基于5分钟网格单元内的数据。多样性指数采用香农指数（Shannon Index）计算，数据源自南加州沿海水资源研究项目（Southern California Coastal Water Research Project，简称 SCCWRP）的鱼类拖网调查数据。该数据集包含1994年和1998年6月至8月期间收集的425次独立渔业拖网调查数据，调查深度范围在2至215米之间。利用ArcGIS软件，创建了5 x 5分钟的网格，并计算了每个网格单元的鱼类多样性均值。
