Coastal Waters nclude the area from a line approximating the mean high water along the mainland or island as far out as 25 miles including the bays, harbors and sounds.
Coastal Upwelling (ocean)
A type of vertical current that arises when offshore winds (or winds blowing toward the ocean) push water away from the shore and deep, colder water rises to replace the water that has been blown out into the ocean. This cold water from deep off the ocean floor brings many nutrients to the surface.
