Underwater Enclosure

Marine science and limnological research extends to water column and reflectance measurements below the surface with the SVC diver-operated underwater enclosures.

Early underwater spectral measurements were made using special fiber optic light guides to bring the reflected energy from the underwater subject to the spectroradiometer located above the water surface. The expensive fiber optic guides proved to have extremely short service due to unintentional injury.

The approach proved it nearly impossible to acquire accurate measurements due to the poor coordination of the instrument operator and diver.

To overcome these difficulties, an underwater enclosure was developed for the GER 1500 Spectroradiometer. With this capability, scientists were able to directly observe the area of interest and direct the spectroradiometer to acquire the desired measurements.
