Objective: Unified, networked access to geographically distributed data from

Observing Systems and Historical Data Archives (focus on in situ data) Method:

Integrate several new, modern and proven, off-the-shelf, Open Source, network-based applications and technology developments

CORBA/Java RMI Data Server – network middleware SGT - Interactive, Java graphics tools NdEdit - Interactive Java in-situ data selecting / subsetting tool LDAP - Directory Services XML - Automated metadata generation tool Habanero - Collaborative tool environment

Dual access: Web and desktop Java application Web help and tutorial

In situ Data collections Data presently available:

TAO El Nino buoy data (realtime) – PMEL Global sea level data (realtime) – University of Hawaii Global Temperature-Salinity Profile Program (GTSPP) – NODC PMEL hydrographic data collection – PMEL

Data in progress: WOCE hydrographic data – Scripps Institution of Oceanography Intl. Pacific Research Center in-situ collection –University of Hawaii WOCE Acoustic Doppler Current Profiler data– University of Hawaii Marine Environmental Data Service (MEDS) Canada

Future plans: ARGO profiling float data WOCE/CLIVAR data DODS proxy server - selected DODS datasets

Uniform network access to distributed observational datasets

Sophisticated Java tools for subsetting large, irregular, in situ data collections

Data fusion and data download From a desktop Java application or the web

Modern, scalable off-the-shelf components Open Source Java, CORBA, LDAP, XML Free and low maintenance

Extensible Scalable Extensible to satellite, gridded products, model results Poised to utilize new networking technology (e.g.,network Quality

of Service, Collaboration) Significant technology spin-offs already realized
