ac-9. Simultaneously determines the spectral transmittance and spectral absorption of water over nine wavelengths. Manual

ac-s. Determines the spectral resolution of in-situ absorption and beam attenuation. The 4 nm resolution allows for spectral "fingerprinting" and deconvolution analysis. Manual

C-Star Transmissometer. Measures the beam transmission (underwater visibility parameter) at 532 nm and the total suspended particle mass at 650 nm. Manual
