Jim Gardner will present the USGS monthly public lecture in Menlo Park on February 25. He will describe multibeam swath-mapping he conducted last summer in Lake Tahoe and display images of the lake bottom. Topics to be covered include:

  • State-of-the-art technology in marine echo-sounding applied for the first time in mapping a lake

  • Collaborative research by the USGS, University of New Brunswick (Canada), and C&C Technologies, Inc. (Louisiana) that yielded more than 65 million depth soundings in 10 days

  • Discoveries of a giant prehistoric landslide and an underwater glacial valley and what they reveal about the history of Lake Tahoe

  • Computer-generated fly-through tours of Lake Tahoe's bottom features

The lecture will take place in USGS Conference Room A, Building 3, Menlo Park, Calif., on Thursday, February 25, at 7 p.m. You can read about USGS research in Lake Tahoe and view images of the lake floor on the Web site.
