Measurement Capabilities of WET Labs' Sensors
 

Biogeochemical property Related IOP Importance Sensor(s)
Chlorophyll absorption Particulate absorption Chlorophyll captures and provides the quantum energy for aquatic photosynthesis. Absorption of packaged chlorophyll is a critical IOP for estimating primary productivity and carbon production in bio-optical models. • ac-9, ac-s
Chlorophyll fluorescence Fluorescence emission In-vivo chlorophyll fluorescence is a sensitive indicator of chlorophyll concentration, though highly dependent on pigment packaging and quantum efficiency of fluorescence. • ECO FL
• WETStar
Particulate mass concentration

 

 Beam attenuation Beam attenuation in the red is linearly correlated with particle mass concentration. Where phytoplankton are the dominant particulates, the beam atteunation coefficient can be correlated to the particulate organic carbon (POC) concentration and can be used to estimate net primary production and biomass-specific production rates. • ac-9, ac-s
• C-Star
Particulate mass concentration Backscattering Backscattering is a less precise proxy of particle mass concentration but is effective over a wide range of concentrations and can be related to the common unitless measurement of turbidity. • ECO BB2F, FLNTU, BB
Phytoplankton composition Spectral absorption Phytoplankton have specific pigment compositions related to species and physiological parameters. Precise absorption spectra can distinguish the bulk ratios of pigments in a given population and can be used for taxonomic and niche identification. • ac-9,
• ac-s
Particle composition: the proportion of pigmented to non-pigmented particles a/b (absorption-to-scattering ratio) Can estimate the abundance of phytoplankton particles relative to the total particle population • ac-9, ac-s
Size distributions Spectral attenuation The hyperbolic slope of the attenuation spectrum in the visible is linearly linked to the slope of the hyperbolic, Junge-type particle size distribution, thus providing a simple means of determining relative proportions of small and large particles. • ac-9, ac-s
Bulk refractive indices—PIC:POC Backscattering ratio
and spectral attenuation		 The strong relationship between the backscattering ratio and bulk refractive index allows a direct estimate of the proportion of organic to inorganic particulate material (POC:PIC) • ECO BB
• ECO VSF
Colored dissolved organic matter (CDOM) UV and blue wavelength spectral fluorescence and dissolved absorption Identification of fluorescent amino acids, terrestrial humic and fulvic acids, aquatic humic acids and whitening agents. Composition of chromophoric dissolved organic material based on dissolved absorption spectrum. • CDOM WetStar,
• Filtered ac-9, ac-s

 

WETSAT

The world of aquatic science is changing. Long term data collection systems are enhancing individual research. At the same time, community efforts to understand global systems are developing. Now, more than ever, our modeling and observational methods must change accordingly. Integrated observing systems that address the diverse needs of both the scientific, regulatory and industrial aquatic community will be essential tools in the future.

We have worked alongside some of the world's leading institutes to develop products such as the chemical-free nitrate sensor - MBARI-ISUS and the Water Quality Monitor and have now teamed with leading developers such as WET Labs Inc. to expand our capabilities and continue to provide superior products and customer support.

In response to the unique requirements of water quality managers, WETSAT , WET Labs and Satlantic operate as a single, unified team to meet your needs. Combined, we provide the best solutions for your unique challenges. With the strength of our three-company team, you can be sure of a comprehensive and coordinated approach.
