| Zusammenfassung: | An apparatus and method for measuring the diffuse absorption coefficient of seawater provides reliable readings. An emitter of pulsed light is disposed below the water's surface and an irradiance receiver is located between the pulsed light emitter and the water's surface. Because the irradiance receiver is facing downward, is separated from the light emitter a given amount and may be disposed a suitable distance below the water's surface, reliable day and nighttime readings are obtained that are unaffected by atmospheric or surface conditions. |
