C-OPS
Compact-Optical Profiling System

The Compact-Optical Profiling System (C-OPS) is an in situ water-based radiometer system developed at Biospherical Instruments. It measures vertical profiles of ocean radiance and irradiance from 150 to 300 m depth. It consists of two radiometers operating across the 250-1650 nm wavelength range. C-OPS has a typical sampling rate of 125 Hz and a vertical resolution of less than 1 cm. It also includes ancillary sensors that measure water temperature, pressure, and humidity.
