Science / Tides and Currents / Geopotential: The unit of geopotential difference, equal to the gravity potential of 1 meter squared per second squared, m2 / s2, or 1 joule per kilogram, J / kg.

Geopotential Anomaly

Science / Tides and Currents / Geopotential Anomaly: The excess in geopotential difference over the standard geopotential difference [at a standard specific volume at 35 parts per thousand (?€°) and 0 degrees C] between isobaric surfaces. See geopote MORE

Geopotential Topography

Science / Tides and Currents / Geopotential Topography: The topography of an equiscalar (usually isobaric) surface in terms of geopotential difference. As depicted on maps, isopleths are formed by the intersection of the isobaric surface with a series of g MORE

Geopotential Difference

Science / Tides and Currents / Geopotential Difference: The work per unit mass gained or required in moving a unit mass vertically from one geopotential surface to another. See geopotential, geopotential anomaly, and geopotential topography. MORE

Geopotential (Equipotential) Surface

Science / Tides and Currents / Geopotential (Equipotential) Surface: A surface that is everywhere normal to the acceleration of gravity. MORE

Dynamic Meter (D)

Science / Tides and Currents / Dynamic Meter (D): The former practical unit for geopotential difference (dynamic depth), equal to 10 geopotentials (dynamic decimeters). See geopotential (dynamic depth) anomaly. MORE

Level Of No Motion

Science / Tides and Currents / Level Of No Motion: A level (or layer) at which it is assumed that an isobaric surface coincides with a geopotential surface. A level (or layer) at which there is no horizontal pressure gradient force. MORE
