Marine provinces are specific geographic areas of the ocean delineated by common landform (i.e., coastal geology and position of the continental shelf) and water conditions (i.e., temperature, currents, wind patterns, and salinity). In addition, marine provinces may be categorized by the unique flora and fauna (or biota) they support.

Of the open ocean zones, most life is found in the epipelagic zone. This is where light is able to penetrate the ocean, allowing for photosynthetic processes to take place. It extends roughly 200m or 650 feet below the surface. This zone may also be known as the euphoric zone, the sunlight zone, or the photic zone.
