The Biological and Chemical Oceanography Data Management Office (www.BCO-DMO.org) was created to serve scientific investigators funded by the National Science Foundation's Biological and Chemical Oceanography Sections as a location where marine biogeochemical, ecological, and physical oceanographic data and information developed in the course of scientific research can easily be stored, disseminated, and protected, on short and intermediate time-frames. Our main objective is to support the scientific community through improved accessibility to ocean science data. The BCO-DMO manages existing and new data sets from individual scientific investigators and collaborative groups of investigators through use of open-source software, and makes these available via any standard Web browser. This presentation focuses on the current status of the University of Minnesota's OGC-compliant MapServer interface to these data including the ability to view the entire data collection in the map view, and multiple ways to select data i.e by Program, Cruise, Principal Investigator, Project, Sensor/data type, etc. The presentation also reviews the additional metadata necessary to support several different data display options. The system's interface provides for simple and advanced data searches and several interoperability features. Using the MapServer interface to the BCO-DMO data system provides a geospatial context in which to discover the availability of data sets that are of potential interest.
