A tide of decreased amplitude, occurring semimonthly one or two days after quadrature .
Industry:Earth science
1. An integral multiple or submultiple of a given frequency; a sinusoidal component of a periodic wave.
2. A signal having a frequency that is a harmonic (sense 1) of the fundamental frequency.
Industry:Earth science
A unit of measurement which indicates the amount of solids in the water by quantifying the degree to which light travelling through a water column is scattered by the suspended particles.
Industry:Earth science
A gravitational solar or lunar tide in the ocean or atmosphere which is in phase with the apparent motions of the attracting body, and consequently has its local maxima directly under the tide-producing body and on the opposite side of the earth. A gravitational tide which is in opposite phase to the apparent motions of the sun or moon is called a reversed tide .
Industry:Earth science
A tide in which the diurnal and semidiurnal components are both prominent. Diurnal inequality is present in high waters , low waters , or in both.
Industry:Earth science
A fixed point number composed of the most significant digits of a given floating point number. The positive decimal part of a common logarithm.
Industry:Earth science
A listing of all the sources of heat transfers for some thermodynamic system, to account for the total heat transfers into or out of the system.
Industry:Earth science
A submarine plateau or irregular area adjacent to a continent , with depths greatly exceeding those on the continental shelf , but not as great as in the deep oceans.
Industry:Earth science
A tidal current which flows alternately in approximately opposite directions, with periods of slack water at each reversal. Such currents occur chiefly in restricted channels; open sea areas generally have rotary currents .
Industry:Earth science
A multiyear surplus accumulation of snowfall in excess of snow melt on land and resulting in a mass of ice at least 0. 1 km2 in area that shows some evidence of movement in response to gravity. A glacier may terminate on land or in water. Glacier ice is the largest reservoir of fresh water on Earth, and second only to the oceans as the largest reservoir of total water. Glaciers are found on every continent except Australia.
