In geology, a marginal sea is the sea bordering continents, semi-isolated from open ocean by island arc or land ridge, and underlain by oceanic crust (Karig, 1971). Thus a marginal sea is a deep-sea basin with water depth in general over ~3,000 m, while its slopes and shelves are called as its continental margins.
