Dr. Tom Goreau and a crew of volunteers through Vone install his "Biorock" artificial reef arrays on the first reef off LBTS yesterday. The reef array comprised of reinforcing steel is impressed with a weak electric field supplied by solar panels on a stationary buoy over the site. This field aids in the "plating" of carbonate accretions on the rebars and transplanted corals attached to the array. The impressed field reportedly cathodically protects against corrosion of the rebar while promoting even more vigorous coral growth than might be observed on adjoining natural reefs. The natural reefs are taking some serious hits in these times sad to say. It will be interesting to see how this artificial reef performs. Originally it was planned to run power from the shore via the LBTS fishing pier. I understand the pier operators would give permission for this but only if they agreed to pay for rewiring the entire pier?! Next, too bad the power buoy brings aboard a lot of technical difficulties beyond simply promoting carbonate accretion. More about the Biorock concept at http://www.biorock.org


Here is a video of the Biorock system shot on September 28, 2011. The Vone and crew are hitting it hard down here finishing up. Lots of final securing to be done, pinning electrical cable to the bottom, securing anodes, cleaning and ferro-cementing in the array legs into the holes drilled into the bottom. It is looking good. We should have some wind and waves early next week. It will be interesting to see how things fare. There are already carbonate accretions on the array near the anode. Shot a lot more stills and video of work underway today.https://www.facebook.com/rick.iossi/videos/10150285423403199/

I recall that Vone and Tom Goreau reengineered the mooring in time to better deal with wave loading in this shallow area.

A video of a portion of the construction of the project. The buoys were eventually lost given the shallow, hostile wave environment and the array design.
