Now, I ran across another graphic I had to do some work on to get it sized to fit a standard(800 X 600 resolution) window. You'll notice re our previous discussion a possible(?) sea level "spike" at ~80,000ya. This more or less coincides with a previous argument about the age(s) of the bays being ~70,000ya. HOWEVER, the sea level indicated at that time was only ~30' above present level(s).
I know you have stated you believe the bays were formed within a marine environment, and if you're correct, something is amiss. What are the chances these marine sediments could have been deposited in existing bays by something like a "mega" tsunami? Or possibly some other process??? Or are there actual sediments deposited over a long period of time?
Anyway, getting late, so here's the graphic witout further comment. Original found HERE.
