Thermocline

Science / Weather / Thermocline: A vertical negative temperature gradient in some layer of a body of water which is appreciably greater than the gradients above and below it. In the ocean, this may be seasonal, due to the heating of the surface water in the summer, or permanent.

Internal Tide

Science / Tides and Currents / Internal Tide: A tidal wave propagating along a sharp density discontinuity, such as a thermocline, or in an area of gradually changing (vertically) density. MORE

Progressive Wave

Science / Tides and Currents / Progressive Wave: A wave that advances in distance along the sea surface or at some intermediate depth. Although the wave form itself travels significant distances, the water particles that make up the wave merely desc MORE

Deep Layer

Science / Marine Biology / Deep Layer: The layer extending from the lowest part of the thermocline to the bottom MORE

Oxygen Minimum Layer

Science / Marine Biology / Oxygen Minimum Layer: A depth zone, usually below the thermocline, in which dissolved oxygen is minimal MORE
