True, the large-order transgressions and regressions are driven by an increase or decrease in the creation of oceanic crust. That is what caused the development of the Western Interior Seaway during the Cretaceous. Much of the western US was covered a couple hundred feet of water. But the small-scale changes are driven primarily by glaciation which a function of climate.

If I read you correctly, on that we can agree. I have no doubt that major portions of the continent were underwater at one time, thus the sedimentary build ups. Very different from the sea level rising and falling independent of the continental heaving.

I hope we arent upset with each other after this.
