View, Subset and Download Data
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
- - download the data in NetCDF format

Bacterial transcriptional response to picoeukaryote Micromonas commoda
Abstract:
Marine biogeochemical cycles are built on interactions between surface ocean microbes, particularly those connecting phytoplankton primary producers to heterotrophic bacteria. However, direct influences of bacteria on phytoplankton physiology are poorly known. In this study, three marine bacteria (Ruegeria pomeroyi DSS-3, Stenotrophomonas sp. SKA14, and Polaribacter dokdonensis MED152) were co-cultured with green alga Micromonas commoda, and the phytoplankter's transcriptome was studied by RNASeq. The presence of each bacterium invoked transcriptomic remodeling by M. commoda after 8 h in co-culture. Some aspects of the algal transcriptomic response were conserved across all three bacteria, while others were restricted to a single bacterium. M. commoda had both rapid and extensive responses to heterotrophic bacteria.
