Acoustics on a SWATH vessel

The best part about studying oceanography is the need to experience the ocean fi rst hand. In order to fulfill the requirements of my Oceanography Master’s degree, I had the opportunity to spend two weeks at sea. In the middle of May, I flew from Halifax to Fort Lauderdale, Florida and boarded the R/V Planet, which would take...

In July 2012, I had the opportunity to conduct fieldwork in Grand Passage, Nova Scotia. This tidal channel lies between Brier Island and Long Island, along the Digby Neck, and is proposed for in-stream tidal turbine development. We collected acoustic measurements from a bottom-mounted frame with a hydrophone on it. The greatest...
