Argo • The ocean’s role in climate • Global system for sustained observation of ocean temperature, salinity, velocity
Glider observations on the US coast • Gliders’ role in ocean observing system is to patrol the boundaries, connecting the coastal and open ocean
Sections on CalCOFI line 80 • Depth-average velocity • Salinity • Along-shore velocity • Acoustic backscatter • Chlorophyll fluorescence
Dissolved oxygen and ocean acidification • Using a proxy relationship to derive aragonite saturation (Alin et al. 2012)
The SoCal Niño Index • Temperature anomaly at 50 m • We are experiencing weak El Niño conditions now.
Gulf Stream • Cross Atlantic 2009 • Cross Gulf Stream 2004
Operations Piloting Glider Data Center Users Data management • National standards to ease exchange of data from regional glider operators • Real-time distribution • Quality control • Archiving
