Bay, Gulf

Shallow marine

Overview

A sedimentary system composed of a series of sedimentary facies at seashores surrounded by lands such as peninsula. The facies are less subjected to the influences of waves and currents than storm-dominated shelf. Bays are protected from waves and currents by sand spits, longshore bars and barrier islands at the entrances of bays.
