Single beam sonar to multi-beam WASSP sonar - finds HMS INVESTIGATOR - HMS EREBUS & TERROR ?

Start here - view this video then view the next video, then next video etc...

2011 - GREY GOOSE with Wide Angle Scanning Sonar Profiler (WASSP)

 - Bathymetric survey over 10,000nm voyage (including the Northwest Passage)
 - 120 degree beam will achieve more accurate survey area from one track line than previously available - new hydro data - new areas - better accuracy - best safety for navigation
   - Increase Arctic navigation safety - two ships went aground in 2010, one with 6 million gallons of diesel - luckily there was no oil spill - not if but when - accurate navigation charts are vital to maritime safety.
