Questions
• On what temporal scale does salinity vary?• On what spatial scale does salinity vary?• Coupled models?

Summary
• Temporal variation present in salinity– Tidal at some sites– Event-driven– Short and long-term
• Spatial variation present between NERR sites• Investigate if finer spatial variation exists
