The underwater optical package was deployed on October 28 2009. The package consists of four sensors and associated hardware.
The WETLabs WQM measures Conductivity, temperature, pressure, dissolved oxygen,chlorophyll fluorescence and turbidity
A WETLabs WETStar fluorometer measures coloured dissolved organic matter fluorescence
A WETLabs ac-smeasures particulate and dissolved absorption and attenuation spectral coefficients
A WETLabs BB9 is used to measure total backscattering coefficients
