ABSTRACT OF THE DISCLOSURE An underwater light scattering sensor is disclosed that includes a light source, light stop and a light detector mounted on a planar support capable of measuring nearly all suspended particle concentrations found in natural waters, 1 µg/l to 3 g/l. The sensor is designed to measure light scattered at nearly all angles, which includes forward scattering, back scattering, and multiple scattering, from suspended particles in water through a very short light path length. The small and simple design of the sensor allows it to be produced at low cost, permitting its use in both expendable and non-expendable applications for the detection or measurement of suspended particulate concentrations in water. The magnitude of the scattered light measured by the sensor is proportional to the suspended particle concentration in water, provided the nature of the particles does not change.
