Summary

These data are in seven tables relating to surveys of eelgrass (Zostera marina) and widgeongrass (Ruppia maritima) beds in embayments of the north Pacific coast of Baja California, Mexico. The tables provide environmental conditions, eelgrass and widgeongrass abundance, and measurements used to estimate their aboveground biomass. These tables also provide information on percent cover, location, and tide height of eelgrass, widgeongrass and seaweeds, and water conditions during the survey.

Purpose

The north Pacific coastal waters of Baja California, Mexico contain extensive beds of eelgrass and widgeongrass, but the status and trends of these seagrasses are unknown. These data were collected to provide point-sampling survey to determine eelgrass (Zostera marina) and widgeongrass (Ruppia maritima) abundance, distribution, and ground-truthing data for an effort to classify and map the spatial extent of these seagrasses.
