Last updated 10/02   EG & G 500 and 1000 kHz Side-scan Sonar Co-owned with the Hobart William Smith Geosciences Department Purchased with a grant from the National Science Foundation Analyses: Like sub-bottom profiling, side-scan sonar records sonic reflections along cruise-track survey lines that provide an 'image' of the underlying stratigraphy of marine and lake bottom sediments. The EG & G system is able to image a 50 to 200 meter survey swath width with 1 to 10 meter resolution. Related Research: This system has been used to collect data for the following research: Eastern Lake Ontario, NY state: study of bottom and coastal sediment distribution and dynamics Lagoon of Venice, Italy: study of the evolution of tidal channel migration within this subsiding basin New South Wales, Australia: study of estuarine sediments and the history of tidal "lakes"
