Abstract:

Large scale surveys have been made of the horizontal and vertical distributions of turbidity in the waters of Gulf St Vincent in South Australia. The beam attenuation coefficient at a wavelength of 530 nm was determined from measurements made with a transmissometer operated from a boat. Both horizontal and vertical stratification of turbidity was observed and explanations for these two conditions are offered. Two methods for determining water turbidity from an aircraft were investigated. They involved measuring the amplitude and attenuation of the backscatter envelope from a laser pulse transmitted from the aircraft into the water. The relative merits of the two methods are evaluated. Author
