A method of determining the Volume Scattering Function of Ocean Waters in the backward direction using a Satellite Ocean Color Sensor the said method made to exploit the geometry of the sun-ocean-satellite detector to function as a backscatter system comprising of the sun [as a source of radiation, the ocean as the sampling volume [, and the satellite ocean color sensor [as the detector of the backscattered flux from the ocean emanating from separate ocean pixels arranged on a scan line across the track of the satellite payload and arriving at corresponding pixels on the CCD array detector of the satellite sensor [; the output signals from each electronic pixel of the detector is shown to be related to the Volume Scattering Function at a fixed scattering angles (&#x3c8;) which bears a direct relation to the cosines of the solar incident angle (&#x3b8;) and the angle (&#x3b8;) of the upwelled flux at the ocean surface, the Remotely Sensed Reflectance (Rrs), and the diffuse attenuation coefficient (Kd) thereby resulting in a new product of the Volume Scattering Function at fixed backscattering angles.

The present invention relates to a pressure housing for in-water pressure based systems and to a method for improving the life of the transducers and electronics of underwater systems by maintaining a humidity-free and clean environment around them by avoiding the entry of humidity, dust, or any suspended particles in the air during occasional data offloading and battery replacement in a humid and dust-laden field station; improving the ease of closing and opening of the pressure housing by the use of a novel arrangement thereby avoiding the use of conventionally employed cumbersome protruding and corrosion-prone locking devices such as screws, bolts, or clamps; and implementing reliable transmission of water pressure to the pressure port of the transducer, simultaneously minimizing the errors arising from dynamic pressure effects, preventing its chemical corrosion from saline water, and arresting bio-fouling in the vicinity of the pressure inlet.
