Inner Shelf


The Inner Shelf is the region between the mid continental shelf, including waters of about 50 m and seaward, and the surfzone where surface waves break in very shallow water of only a few meters depth. The inner shelf connects the wind-driven continental shelf and the shore. There is much interest in how water and material move across the inner shelf. For example, sediment, nutrients, plankton, and waters low in dissolved oxygen or high in CO2 (low pH). It is a challenge to work in the inner shelf due to strong currents and potentially large waves.
