...I assumeing it rooted into coral...very innovative to use a non stable base like those balls for the reef...it is quite differetn from the artificials over on this coast where we want them as undesturbed as possible for the small corals to take hold and propagate.
/QUOTE] and [quote='LunkerBuster','http://spearfishing.world/forums/index.php?thread/&postID=38186#post38186']me too, provided they do it right.
I wonder if any of the "reefballs" from the east coast have been used over there...
LB - it's not exactly what you think....:" The rocks, quarried at Catalina Island, are roughly the size of medicine balls and scattered in a single layer on the sand, not piled on top of each other".
these are quarried granitic bolders of "medicine ball size"..... they are not balls - and they are not coral.
"Kay said the goal was to create a dynamic ecosystem in which the boulders are jostled during storms so they can clear out patches of old-growth kelp and create a natural mosaic."
“To get giant kelp coming back generation after generation, there always needs to be bare rock on the reef, and you are only going to get that if you have an unstable reef,” he said.
Of course, we get bare rock from the urchins eating kelp and storms tearing loose kelp..... we have massive kelp beds on rock reefs that don't move.
Long term... not sinking...or getting buried in sand. especially if they move....is a big deal. The 30' depth provides good conditions........ good light, long shore sediment transport is shallower, and still enough turbulence to keep finer sediment moving. Some of the local divers may have noticed that we have a 30' submerged terrace along parts of southern CA. This dates to about 6000 years ago when we had a pause is sea-level rise..... "beach cobbles" are common on the submerged terrace.
The current success of kelp growth comes in a period of unusually cold water summer........ time will tell if the new reef works..... I would have preferred to see a reef with more relief and shelter/ holes.
I hope their design works.
