BCO-DMO is preparing to move to a new data access system that provides more functionality and features. This system, called ERDDAP, is free and open source with a strong and growing user community. Currently, we are providing the following data access and download capabilities for datasets as we work through our legacy data holdings. These capabilities will soon be available for all data at BCO-DMO:Data Access
- - view the data in an HTML table
- - filter the data before viewing or downloading in a variety of formats
- - download the data with comma-separated values (Excel-ready)
- - download the data with tab-separated values (Excel-ready)
- - download the data as GeoJSON. Try it out at geojson.io
- - download the data as a valid MATLAB file

Invertebrate survival: Invertebrate survival rates from feeding experiments, conducted at Bodega Marine Laboratory, where food sources (eelgrass (Zostera marina) genotypes) were varied
Abstract:
Seagrass meadows are among the world's most productive ecosystems, and as in many other systems, genetic diversity is correlated with increased production. However, only a small fraction of seagrass production is directly consumed, and instead much of the secondary production is fueled by the detrital food web. Here, we study the roles of plant genetic diversity and grazer species diversity on detrital consumption in California eelgrass Zostera marina meadows. We used three common mesograzers—an amphipod, Ampithoe lacertosa, an isopod, Idotea resecata, and a polychaete, Platynereis bicanaliculata. In this experiment, we raised communities of either Ampithoe lacertosa or communities of all three mesograzers on either no food, eelgrass detritus from a single clone, or eelgrass detritus from 3 of from 6 different clones. Under monospecific grazer assemblages, plant genetic identity but not diversity influenced detritus consumption. However, more realistic, diverse mesoconsumer communities combined with high plant-detrital genotypic diversity resulted in greater consumption and grazer survival. These data are illustrated in figure 6 of Reynolds et al., 2017 (DOI:10.1111/oik.04471).
