nearshore zone
Earth science; Physical oceanography
A zone extending from the upper limit of a beach to the offshore. In terms of the beach profile, it consists of (progressing seawards) the backshore, foreshore and inshore. In ...
nekton
Earth science; Physical oceanography
One of three major ecological groups into which marine organisms are divided, the other two being the benthos and the plankton. Nekton are strongly swimming pelagic animals such ...
neritic
Earth science; Physical oceanography
Living in coastal waters as opposed to living upon the high seas, i.e. oceanic. A division of the pelagic portion of the ocean that overlies the continental shelf.
nested modeling
Earth science; Physical oceanography
In climate modeling this is a method for obtaining improved regional climate change predictions by the use of a spatial hierarchy of simulation models. Output from GCM simulations ...
neutral density
Earth science; Physical oceanography
A density for which three properties should ideally hold: * it should be constant on approximate neutral surfaces; * its horizontal gradients should coincide with the horizontal ...
neutral trajectory
Earth science; Physical oceanography
A three-dimensional path in the ocean defined such that no buoyancy forces act on a water parcel when it is moved a small distance along the path. Neutral trajectories are ...
new production
Earth science; Physical oceanography
Photosynthesis due to the uptake of nitrate. It is so-called because ocean circulation is the only source of nitrate to the euphotic zone and, as such, the nitrate can be thought ...
