Document Summary
Lab 7 physical oceanography: water properties, measured by ctd- conductivity, temperature, depth, temperature: Temperature is an indicator of the intensity of insolation. Deep ocean is pretty much the same temperature all over. Attraction between molecules determines how soluble a particle is. Process which increase salinity of surface water. Cause sea level to rise and fall. Induced by the masses of the sun and the moon. Gravitation force between two objects is proportional to the two masses and to the square distance between them. Bulges result due to the gravitational force and centrifugal force. Two highs, two lows of same height. Sun and earth are perpendicular to the moon. High current speeds are notehe associated with high and low. Capillary dependant on surface tension, electromagnetic. Surface gravity waves gravity is the restoring force. Internal gravity waves gravity is the restoring force. Long waves (30 200m) swell. Two speeds associated with gravity wave propagation:
