At head of title: Lakes Research Branch Technical Note. "NWRI and the Centre Saint-Laurent are cooperating on an assessment of commercially-available echo-sounders for mapping the thickness of modern contaminated sediments. NWRI is contributing the engineering and scientific expertise and CSL is providing the survey equipment, the field support and the test site- Lac St-Louis. This note describes the echo-sounders considered by NWRI and the criteria used to select the sounders recommended for testing. It also discusses some new types of equipment which have some potential for future use"--Introduction, page 1. Echo sounding gccst Sediments gccst Lakes gccst Measurement Rukavina, N. A., author.
