Abstract:

We developed a unique system, called K-SOLO, that is an integration of the Sounding Oceanographic Lagrangian Observer SOLO and a profiling 3-wavelength downwelling irradiance Ed sensor Biospherical Instruments PER-300. The system measures temperature and allows calculation of spectral diffuse attenuation coefficients K at 380, 490 and 555 nm from the depth derivative of downwelling irradiance e.g. K -1ED dEddz. Data is relayed via satellite when the unit is on the surface. By measuring K rather than absolute radiometric quantities or inherent optical properties, the system is not sensitive to changes in calibration or bio-fouling. K-SOLO was deployed from RN Khromov in the Sea of Japan near 410 degrees N and 1340 degrees E in March, 2000 and transmitted profiled data every second day until the middle of August, 2000. The unit was caught by a Japanese fishing vessel and recently returned to SIO. The SOLO unit suffered major damage and can not be re-utlized. The radiometer is being assessed. 15. TERMS
