This is the study of the physics of the earth. Geophysical survey techniques use physical properties themselves (e.g. magnetism) or apply properties to see how the earth affects them (e.g. radar), to determine something about the earth structure.
Industry:Earth science
This radiation law suggests that the wavelength of maximum emission of any body is inversely proportional to its absolute temperature.
Industry:Earth science
Tide occurring when the moon is near maximum declination; the diurnal inequality is then at a maximum.
Industry:Earth science
Tide occurring when the moon is near the equator; diurnal inequality is at a minimum.
Industry:Earth science
Tide of increased range occurring when the moon is near perigee.
Industry:Earth science
Time during the tidal period when the tide is falling. Compare with flood tide.
Industry:Earth science
Using the same principles as single-beam echo-sounding, multi-beam or swathe echo-sounding is a method of hydrographic survey using hull-mounted arrays which transmit sound beams perpendicular to the direction of the ships track, potentially providing 100% coverage of the seafloor.
Industry:Earth science
Vortical structures that result from the growth and nonlinear development of unstable waves in a shear flow. The billows get their name from the instability responsible for the growth of the unstable waves: Kelvin-Helmholtz instability.
Industry:Earth science
Wave refraction is the process by which wave crests are bent according to variations in seabed contours. This is because as a wave enters shallow water its speed becomes a function of water depth, which causes a change in wave direction in differing water depths.
