The UK charity dedicated to the protection of the marine environment and its wildlife.
Long high swells which have increased in height, almost to the breaking point, as they pass over shoals or run in shallow water.
Industry:Earth science
Long, narrow islands of sand and/or gravel that are usually aligned parallel to the shore of some coasts.
Industry:Earth science
Marshy low lying area in a stream's floodplain. Commonly found behind levees.
Industry:Earth science
Measurement of atmospheric humidity. Absolute humidity is the mass of water vapor in a given volume of air (this measurement is not influenced by the mass of the air). Normally expressed in grams of water vapor per cubic meter of atmosphere at a specific temperature.

Near a boundary in a rotating system, a Kelvin wave propagates with wave crests perpendicular to the side wall and wave height greatest at the side wall to the right of an observer looking in the direction of wave propagation. The wave height decreases exponentially from the side wall with e-folding length scale equal to the Rossby deformation radius c/f, in which f is the Coriolis parameter and c is the phase speed of the wave in the along boundary direction. In the shallow water approximation the waves are non-dispersive with frequency \omega = +/- c k, in which k is the along boundary wavenumber and the phase speed c = (gH)^(1/2) with g the acceleration of gravity and H the mean fluid depth. Related to Kelvin waves in a channel are Poincare' waves.
