The wave base is the maximum depth at which a water wave's passage causes significant water motion. [1] In this portion of the coastal marine environment, only the larger waves produced during storms have the power to agitate the seafloor.

The lower oceanic crust is the lower part of the oceanic crust and represents the major part of it (volumetrically biggest part). [1] It is generally located 4–8 km below the ocean floor and the major lithologies are mafic ( ultramafic and gabbroic rocks) which derive from melts rising from the Earth's mantle . [ 2 ]
The following outline is provided as an overview of and introduction to Oceanography.. Thermohaline circulation. Oceanography (from Ancient Greek ὠκεανός (ōkeanós) 'ocean' and γραφή (graphḗ) 'writing'), also known as oceanology, sea science, ocean science, and marine science, is the scientific study of the ocean, including its physics, chemistry, biology, and geology.
River – a narrow strip of water that flows over land from a higher elevation to a lower one; Tributary – a small river that flows into a larger one; Estuary – the piece of a river that flows into the sea or ocean; Strait – a narrow area of water connecting two wider areas of water, also sometimes known as a passage
[198] [199]: 33 A body plan refers to a blueprint which describes the shape or morphology of an organism, such as its symmetry, segmentation and the disposition of its appendages. The idea of body plans originated with vertebrates, which were grouped into one phylum. But the vertebrate body plan is only one of many, and invertebrates consist of ...
There are several different areas or zones in the ocean. The area along the bottom of any body of water from the shore to the deepest abyss is called the benthic zone . It is where decomposed organic debris (also known as ocean 'snow') has settled to form a sediment layer.
As of 2010 a number of different outputs are generated, including a sub-set of the original measurements that satisfy some conditions (e.g., most representative likely soundings, shallowest in a region, etc.) or integrated digital terrain models (DTM) (e.g., a regular or irregular grid of points connected into a surface).
An anchialine system is a landlocked body of water with a subterranean connection to the ocean. Depending on its formation, these systems can exist in one of two primary forms: pools or caves. The primary differentiating characteristics between pools and caves is the availability of light; cave systems are generally aphotic while pools are ...
