MCDV and Side Scan SONAR
« on: March 06, 2005, 01:56:53 »
Technical question that a fixed wing flunkie such as myself has no knowledge...

There is an MCDV coming up the coast some time in the future (sorry guys, ship movements are OPSEC) to look for the Beaver float plane that went down off Campbell River, BC.  The water in that area is approx. 600' deep.  How effective is the Side Scan SONAR that our MCDVs carry (within reason - no details required) ?  I know that we had MCDVs in Lake Ontario looking for Avro Arrow models - will it be able to do the job here in BC?

Well seeing how detailed the side scan details are of Halifax harbour is I would say its one of the best features of the MCDV.

Only when it's more then 48hrs away!!


It's not my trade, so I'm not all that knowledgeable on this, but hopefully some others that I know are out there will fill in the high points (Cronicbny, I mean you...).   What I do know though is that the gear has been trialled out here (B.C.) numerous times, but most recently just a month or so ago.   And trialled successfully too.   There is also other gear that can be taken for mission-specific to aid in Route Survey, dependent on the depth, area, terrain etc.

Sorry, I know that didn't answer much...

Zoomie, can I assume that you have been part of the search so far to know about what's happening next?

Guys,

I think this goes into "CAPABILITIES AND LIMITATIONS" discussions.  I am not sure that it is appropriate for an open forum?

This is all open source

The 511 side scan sonar is capable of operating in upto 200m of water... so 600' fits right in there. The sonar on the 511 is generally considered one of the best on the market as far as detail goes... the exact detail level is classified, however it's comparable to commercially available units (read Klein 5500). What makes the 511 perfect for this job is it's depth capability, accuracy, and, relative platform stability (easier to use than a 200lb 5500 sonar lowered by hand off a skiff). The bottom conditions on the west coast are also quite favourable for side scan sonars.

Hopefully the results of this will prove the equipment worthwhile... the sonar has had a bad go of things in the last few years. Of course, the flip side... if it doesn't work... the Navy will look stupid. I have faith that the system will perform capably.

We are kept in the proverbial loop.   RCMP is now handling the crash as a missing persons case.   More to follow once pertinent details are released officially to the public.

Thanks for the good Gen on the system Cronicbny...   It certainly seems like excellent conditions for this unit to locate any wreckage and hopefully give closure to the remaining victim's families.

I was on the original search in 2005, its amazing how far the technology has come.

And I ended up working at Route Survey for a year as the Side-scan SONAR tech.

Good times.
