Variability of GOM Transport
Sources of variability:  (standard deviation)/(6 month mean) for transport along Pen Bay/Georges Bank axis, not including coastal current.
•Hydrographic variability, 30 to 40%
•Scotian Shelf inflow variability, about 20%
•Winter winds, about 10%.
Open questions? (one of many!)
•What is timescale of hydrographic variability?
What we know best is not what is important on 6 month or longer timescales
