Point Sampling Data for Eelgrass (Zostera marina) and Widgeongrass (Ruppia marina) Abundance in Embayments of the North Pacific Coast of Baja California, Mexico

공공데이터포털

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.

Point Sampling Data for Eelgrass (Zostera marina) and Seaweed Distribution and Abundance in Bays Adjacent to the Izembek National Wildlife Refuge, Alaska

공공데이터포털

This data package is comprised of nine tables relating to surveys of eelgrass beds in Izembek and Kinzarof Lagoons, Izembek National Wildlife Refuge, Alaska (2007-2024). The tables provide environmental conditions, eelgrass abundance, distribution, and measurements used to estimate overall biomass.

Mapping Data of Eelgrass (Zostera marina) Distribution, Baja California, Mexico

공공데이터포털

Provided here are three vector geospatial datasets that characterize the distribution of (1) eelgrass (Zostera marina), (2) salt marshes, and (3) mangroves in three bays along the west coast of the Baja California Peninsula, Mexico (Bahia San Quintin, Laguna Ojo de Liebre, and Laguna San Ignacio). These data were derived from satellite imagery (Landsat 5 TM) acquired on three different days (1992-09-05, 1999-03-24, 2000-05-11). After pre-processing, imagery was classified into land cover categories. The habitat distribution data were then extracted from the raster grid and converted to vector data.
