Neritic , derived from the Latinized name Nerine for a sea nymph in Greek mythology ( Nereïde ), is the attribute for the mostly well-lit shallow water zones of the sea on the open continental shelf . The Neritic sea area extends between the coastal zone, the littoral , and the upper edge of the continental slope , that is, over the regions relatively close to the coast to a depth of about 200 m. In some ecological classification schemes of the marine regions it only includes the free water column without the benthal . It is then considered part of the pelagialand is called the neritic-pelagic zone . The corresponding part of the bent neck is then called the sublit (t) oral zone (not to be confused with the sublittoral of the coastal zone). Towards the sea, the Neritic Zone, at the transition from the shelf to the deep ocean basin, is followed by the pelagial in the narrower sense or the oceanic-pelagic zone and, with regard to the zoning of the Benthals, the Bathyal .

The Neritic marine areas only take up about 5% of the world's oceans, but due to their good transparency and the relatively high content of nutrients that are brought into the shelf seas by rivers, they are particularly rich. As a result of the shallow depth, there is also a thorough mixing and thus aeration (oxygenation) of the entire water column.

In geology , the adjective neritic refers to shelf sediments and sedimentary rocks, provided that they were still deposited in relative proximity to the coast (cf. facie types of marine sedimentary rocks and shelf term in the sense of geology ).
