This study used to Spectron Industries SE-590 portable spectroradiometer to investigate a common Midwestern wetland species, Ceratophllum. Primary research objectives were: determine the effect of Ceratophllum on the composite spectral signal upwelling from a column of water, determine the death constraint for remote identification of Ceratophllum, and ascertain the presence of Ceratophllum in chlorophyll-laden water. Characteristic absorption features at 443 nm and 670 nm decreased with increasing depth and also as the algal chlorophyll concentrations increased. A wavelength shift in the NIR, associated with increasing depth was found to exist for water columns relatively free of algal chlorophyll as well …
