Results are presented from a series of studies conducted at the Department of Energy (DOE) Savannah River Plant (SRP) with the NASA Airborne Oceanographic Lidar (AOL). These studies included a topographic survey of a {approximately}1000 acre lake basin (presently designated L Lake) which had been excavated for use as a cooling pond for L Reactor; a study of the movement of discharged cooling water in Pond C and the warm arm of Par Pond using Rhodamine WT dye as a tag; initial baseline studies of the vegetation cover of the Steel Creek corridor (through which the outflow of L Lake is carried to the Savannah River); and a demonstration of potential forestry applications of the AOL. These investigations were conducted over a 3-day period in June 1985. The AOL is an advanced airborne laser system capable of making temporal or time history measurements of laser backscatter (bathymetry mode) or spectral measurements of laser induced fluorescence from waterborne constituents (fluorosensing mode). The AOL is flown together with auxiliary instruments and camera systems on board a four engine P-3A aircraft. Recent modifications to the AOL allow in-flight changes between the two basic operational modes of the instrument which permitted the topographic study to be conducted on the same flights as the fluorescent dye study. The L Lake topographic survey represents a state-of-the-art demonstration of airborne laser surveying capability.
