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
- - download the data in Ocean Data View format

A compilation of dissolved noble gas and N2/Ar ratio measurements collected from 1999-2016 in locations spanning the globe
Abstract:
Inert gases dissolved in the ocean are powerful tracers of the impact of physical processes on gases, particularly air-sea gas exchange (by both diffusive and bubble-meditated processes), temperature change, atmospheric pressure variation, mixing between different water masses, and ice processes. We have compiled a global ocean database of dissolved neon, argon, and krypton measurements, supplemented by helium, xenon, and nitrogen/argon (N2/Ar) ratios in some locations. Samples were collected on board multiple research cruises spanning the period 1999 through 2016 and analyzed by mass spectrometry at four different shore-based laboratories (University of Victoria, Woods Hole Oceanographic Institution, University of Washington, and Scripps Institution of Oceanography).
