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.
