Recommendations for estimating suspended solids in the UMRS Ahearn, S. C., R. D. Martin, and J. H. Wlosinski. 1989. Recommendations for estimating suspended solids in the Upper Mississippi River System using remote sensing. Report by the University of Minnesota, St. Paul, Minnesota, and the U.S. Fish and Wildlife Service, Environmental Management Technical Center, Onalaska, Wisconsin, August 1989. EMTC 89-01. 23 pp. (NTIS # PB89236715/AS) ABSTRACT The purpose of this report was to determine the feasibility of obtaining estimates of the concentrations of suspended solids in 1300 miles of the Upper Mississippi River System using remote sensing. The report includes: 1) a review of measured concentrations of suspended solids in different portions of the system. 2) a literature search of the spectral characteristics of suspended solids in water bodies in the laboratory and field and the use of remote sensing for qualitative and quantitative estimation of suspended solids in water bodies; and 3) the steps necessary to initiate a study to obtain estimates of error which would be needed because of the length and diversity of the Upper Mississippi River System.
