247 - LAKE EUTROPHICATION AS INDICATED BY ERTS SATELLITE IMAGERY Dr, James P. Scherz University of Wisconsin, Madison, Wisconsin Dr, John F, Van Domelen Norwich University, Northfield, Vermont Dr. Kenneth Holtje U.S. Forest Service, Milwaukee, Wisconsin William Johnson State University of New York, Syracuse, New York ABSTRACT Light reflectance from water in the laboratory always correlates to the water quality parameter of turbidity. This turbidity is caused by suspended solids in the water and for a particular type of material there is a good correlation between the weight of these suspended solids and turbidity. However, this correlation is different for different types of material. When this suspended material is living green matter as in an eutrophic lake, the changes in reflectance can be detected as changes in brightness on a particular aerial image. Two test sites have shown that there is indeed a good correla tion between the brightness on an ERTS image and lake eutrophi cation. ZUSAMMENFASSUNG Von Wasser reflecktiertes Licht in Laborexperimenten steht in direkter Beziehung zu dem Wassergüteparameter Trübheit. Diese Trübheit ist durch schwebende Stoffe verursacht und für bestimmte Materien steht in direkter Beziehung zu der Menge des Stoffes im Wasser. Diese beziehung ist jedoch unterschiedlich für verschiedene Stoffe. Wenn das schwebende Material lebender Grünstoff ist, wie in einem eutrophishen See, kann die veränderte Reflektion in unterschiedlicher Hellheit an einer Luftaufnahme erkannt werden. Zwei Versuchsstandorte zeigen hohe Korelation zwischen der Hellheit eines ERTS Bildes und Seeeutrophierung.
