Baltic sea derelict gear training and conferencE Update

Stralsund & Sassnitz Germany

Innerspace Exploration Team and Fenn Enterprises have just returned from Germany where we provided side scan sonar training dealing specifically with detection of nets in the Baltic. The participants were from World Widlife Fund, Marelitt Baltic and the Global Ghost Gear Initiative from Germany, Denmark, Netherlands, Poland, Sweden, Estonia, Peru, and Hong Kong.  These countries are all in the beginning phases of implementing derelict gear programs and the purpose or our trip was to demonstrate our proven sonar techniques, present on the success of the Derelict Gear program in the Salish Sea, and provide hands-on training to scientists from various disciplines, some of whom already had some side scan experience and their own sonar equipment.  

We spent four days on the water in all kinds of sea states demonstrating proper deployment and survey techniques.  A very important component to our training is post processing where the participants learn how to interpret the data.  We spent about 2.5 hours on post processing each evening.  We also performed ground-truthing with divers to verify targets and also setup a test bed where we set a known target (chain/net) so everyone could experience detection of derelict gear.

For this project Marine Sonic provided a demo ARC Chirp side scan system.  This is an upgraded version of the sonar we used in the Salish Sea. Our training was a huge success.  Discussions afterwards revealed that even more hands-on training will be needed for the teams who will be responsible for performing the sonar work and we will be scheduling a return visit for this purpose.

Port Gardner and Mukilteo WA

225 pots recovered - see how it's done in the video below.


DERELICT Fishing gEAR Removal project

Location and removal of lost or abandoned fishing gear and related debris from the waters of the Northwest Straits. We have located and recovered over 1000 crab pots to date. Recently we have expanded this project to the waters of Humboldt and Monterey counties in California and also assisted in training U.S. Navy divers in net removal techniques. For more information see the Northwest Straits Foundation Derelict Gear site.
