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
