The southernmost parts of the Atlantic, Pacific, and Indian oceans converge into a cold, oceanic water mass with singularly unique biologic and physical characteristics.
Pelagic sediments, either terrigenous or biogenic, are those that are deposited very slowly in the open ocean either by settling through the volume of oceanic water or by precipitation.
As the carbon dioxide is absorbed, it alters the oceanic water chemistry, turning it increasingly acidic.
Thermocline, oceanic water layer in which water temperature decreases rapidly with increasing depth.
Newly discovered deep-sea vents, where life itself may have begun, recycle all of the planet's oceanic water every 10 years.
Halocline, vertical zone in the oceanic water column in which salinity changes rapidly with depth, located below the well-mixed, uniformly saline surface water layer.
The migration was still on, and the fish were showing up, blue-tinted in the clear and cool oceanic water of May.
The public health issue there resurrected lingering bitterness over the $11 million — most of it federal and state money — that was spent to help revitalize the waterfront of a deep-port city famous for more oceanic water pursuits.
Equatorial countercurrent, current phenomenon noted near the equator, an eastward flow of oceanic water in opposition to and flanked by the westward equatorial currents of the Atlantic, Pacific, and Indian oceans.
Halite, sodium chloride (NaCl), is the most familiar example; it often occurs with other evaporite minerals in enormous beds resulting from the accumulation of brines and trapped oceanic water in impermeable basins and their evaporation.
Some nutrients enter the lagoonal waters with the oceanic water that flows through the reef openings, but the dissolved phosphates in the lagoons are probably derived chiefly from bacterial decomposition of the organic matter on the sea bottom, as well as from detritus swept in from the reef surfaces.
