Real-time WISP monitoring Water color spectrum (400 – 760 nm range) A calibrated and quantitative measurement of the

spectrum The spectrum reveals information about parameters in

water influencing light reflection: Chlorophyll-a TSM Colored dissolved organic matter (e.g. humic

acids (CDOM) Vertical distinction (Kd) Secchi disk depth Blauwalgae pigments (Phycocyanine, PC)

Strong points of optical measurements

• No water contact • From any platform (hand, buoy, boat,

airplane, satellite, ISS) and inter-changeable • Measurements : digital physical quantity

(never looses value) • Information translated into relevant

indicators • Large archives of historic satellite data

available • Techniques for interpretation well

understood

Data Validation – Chlor -a

COASTCOLOR: an ESA funded comparison of the 12 world leading algorithms WISP algorithme (AP06) proved to be #1

Validation coast-color in situ data

WISP-3 versus fluoroprobes

14

No quenching effects Combined determination of both CDOM and TSM (no further

calibration required due to light restrictions) One instrument measuring a range of parameters: TSM, Chl-

a, PC, Kd, SD, CDOM,... Algorithms are not sensitive for changes in optical

characteristics

Above water analysis: no biofouling

Flexible in use from various platforms (boat, satellite, aeroplane, on shore

Integrated measurements in the water body (surface and depth)
