Environmental Data Server (EDS)
  • Access to global/regional current and wind data
  • Data from NOAA, NAVY, Regional Associations,
    Universities and commercial providers
  • Aggregation Services (temporal and spatial)
  • Redundancy and Backup
  • Objective Analysis Tools
  • Web Services Protocols

15
SAROPS EDS Data
  • Operational Forecast Model Data
  • Observation Data (NDBC buoys, satellite,
    drifters, Sea Surface Radar, etc.)
  • Seasonal data
  • Tidal databases (harmonic databases)

Conclusions
  • SAROPS - operational in the USCG since January
    2007
  • Use of open standards allows for interoperability
  • Adding improved regional coastal data
  • Need for uncertainty measurements and dispersion
    coeffs
  • Researching new Lagrangian techniques
