The UK charity dedicated to the protection of the marine environment and its wildlife.
The study of the interaction of waves and currents with the coast.
Industry:Earth science
The study of the sea , embracing and integrating all knowledge pertaining to the sea's physical boundaries, the chemistry and physics of sea water, and marine biology.
Industry:Earth science
The study of water depths.
Industry:Earth science
The temperature at which a substance in liquid form freezes, equal to the temperature at which its solid form melts; this represents equilibrium between the liquid and solid phases.
Industry:Earth science
The tendency for linear motion to be deflected in a rotating (non-inertial) reference frame. In most geophysical circumstance, the horizontal deflection of horizontal motion is most significant. Zonal motion experiences an acceleration -f v and meridional motion experiences an accleration f u in which u and v are the zonal and meridional components of velocity, respectively, and f is the Coriolis parameter.
Industry:Earth science
The terrestrial interface area in between land and a water body where there are accumulations of unconsolidated sediments like sand and gravel. These deposits are laid down by the action of breaking waves.
Industry:Earth science
The theoretical temperature at which molecular motion vanishes and a body would have no heat energy; the zero point of the Kelvin and Rankine temperature scales. Absolute zero may be interpreted as the temperature at which the volume of a perfect gas vanishes or, more generally, as the temperature of the cold source that would render a Carnot cycle 100 percent efficient. The value of absolute zero is not estimated to be -273. 15° Celsius, -459. 67° Fahrenheit, 0° Kelvin, and 0° Rankine.
Industry:Earth science
The thermal atmospheric region of the atmosphere between the troposphere and the mesosphere. The lower boundary of the stratospheric region is marked by the tropopause and begins at approximately 13 km; however, this altitude of the troposphere depends on latitude. The upper limit of the stratosphere is marked by the stratopause at approximately 50 km. The stratosphere is characterized by relatively stable temperatures (between -80°C and -50°C) in the lower regions, and begins warming near 20 km, reaching its maximum temperature of approximately 0°C at the stratopause. Stratospheric chemistry is of particular interest to scientists because ozone, the principal substance that shields Earth from incoming solar ultraviolet radiation, is found in the stratosphere. It should also be noted that wind currents in the stratosphere are primarily horizontal in nature.
Industry:Earth science
The thin layer of air adjacent to Earth's surface, extending to the Ekman layer. Thus, it is the lowest layer of the troposphere. Within this layer the wind distribution is determined largely by the vertical temperature gradient and the nature and contours of the underlying surface; shearing stresses are approximate constant. Also called surface layer, friction layer, atmospheric boundary layer, ground layer. Together with the Ekman layer it forms the planetary boundary layer.
Industry:Earth science
The transfer of energy within and through a conductor by means of internal particle or molecular activity and without any net external motion. Conduction is to be distinguished from convection (of heat) and radiation (of all electromagnetic energy).
