What complex geological process must scientists account for when modeling the true elevation of an ancient shoreline marker after the water disappeared?

Answer

Isostatic adjustment

The weight of the water would depress the crust (isostatic adjustment); subsequent rebound after water loss shifts the original elevation marker, which must be factored into calculations.
