3. Ocean Observatories Initiative Ocean Observatories Initiative Approved by the National Science Board for a Future NSF Budget Includes: Coastal Observatories Plate Scale Observatory Global Mooring Observatory

4. Partners University of Washington Woods Hole Oceanographic Institution National Aeronautics & Space AdministrationNational Aeronautics & Space Administration, JPL JPL Monterey Bay Aquarium Research Institute NEPTUNE Canada (IPOST)

5. MARS (the Monterey Accelerated Research System). A cabled observatory in Monterey Bay built with NEPTUNE infrastructure as a proof of concept.

6. Tropical Atmosphere Ocean project Real-time data from moored ocean buoys for improved detection, understanding and prediction of El Niño and La Niña.

7. Issues - Existing ocean observing systems such as TAO & ARGO deal with relatively simple data sets of well known format - e.g. vertical T & Salinity profiles. New sensors cannot be easily fit into the platform or data system. Data transmission from unattended platforms in the middle of the ocean is a problem. ARGO Global Profiling Drifter Array Temp. & Salinity of Ocean Interior

8. E.g., the MBARI OASIS System - Now two moorings in Monterey Bay & two in the equatorial Pacific. M2 M1

9. MBARI OASIS Moorings The OASIS moorings communicate by ARGOS, microwave or packet radio. Adding new sensors becomes a large software configuration issue, particularly for complicated sensors.

12. MOOS software Application software for sensors, user interfaces, databases, etc. Distributed applications are “glued” together by smart network infrastructure

13. Smart network Self-organizing; applications are notified by infrastructure when network configuration changes –E.g., database ingest engine always “aware” of available sensors Enables automatic configuration, remote control, and autonomous coordination of sensors

14. Network configuration “Just plug the sensor in, and it works!” Easily replace, remove, or add a new kind of sensor Remote update of sensor’s driver software Minimal configuration effort by human operators lower maintenance cost

15. Leading technology candidates CORBA Java - JINI LonWorks Universal Plug-n-Play

16. What kind of data will we assimilate in global observing systems? Physical, geophysical observations (T, S, seismicity) - generally sensors are mature. Chemical - nutrients (nitrate, phosphate, iron), gases (carbon dioxide, oxygen) - sensors exist but have not gone commercial. Biological - bio-optical systems are mature, but not very specific. DNA based systems are beginning to appear.

25. Iron (nM) Pseudo-nitzschia australis (cells/L) Does iron regulate toxic plankton blooms (e.g., Wells et al., Evaluation of iron as a triggering factor for red tide blooms. MEPS, 69, 93, 1991)?
