  1. Look ma, no cables!Observing the ocean with underwater gliders • Dan Rudnick • Scripps Institution of Oceanography

  2. The world is going wireless

  3. Wisdom “The chief source of ideas in oceanography comes, I think, from new observations.” Henry Stommel

  4. Stommel’s vision

  5. Argo • The ocean’s role in climate • Global system for sustained observation of ocean temperature, salinity, velocity

  6. Glider observations on the US coast • Gliders’ role in ocean observing system is to patrol the boundaries, connecting the coastal and open ocean

  7. Spray underwater glider

  8. Glider operations

  9. Gliders have carried all kinds of sensors

  10. A growing enterprise

  11. California Glider Network

  12. Sections on CalCOFI line 80 • Depth-average velocity • Salinity • Along-shore velocity • Acoustic backscatter • Chlorophyll fluorescence

  13. Dissolved oxygen and ocean acidification • Using a proxy relationship to derive aragonite saturation (Alin et al. 2012)

  14. The SoCal Niño Index • Temperature anomaly at 50 m • We are experiencing weak El Niño conditions now.

  15. Gulf Stream • Cross Atlantic 2009 • Cross Gulf Stream 2004
