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 geopotential and 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
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
Science / Geology / Magnetic Anomaly: The value of the local magnetic field remaining after the subtraction of the dipole portion of the Earth's field. MORE
Science / Tides and Currents / Specific Volume Anomaly, Or Steric Anomaly: The excess in specific volume over the standard specific volume at 35 ‰, 0°C, and the given pressure. See thermosteric anomaly and specific volume. MORE
Science / Tides and Currents / Thermosteric Anomaly: The specific volume anomaly (steric anomaly) that would be attained if the water were changed isothermally to a standard pressure of one atmosphere. The specific volume anomaly with pressure terms omi MORE
