I mentioned it as an addendum on an earlier comment, I'm going with sea floor rising (due to expanding magma/expanding earth theory) If you follow any of the buoy data reporting here and there, they have posted huge anomalies that most certainly have to be equipment malfunction, or is it? There is controversy about buoys going 'offline' as well, mostly in the south east (Jakarta) area. The rising seafloor would certainly lead to coastline submersion as a counter force This florida video feels even more disturbing than other areas experiencing same thing, maybe cause its our backyard. The sea floor anomalies were occuring around the same time as Sandy if I'm not mistaken, so that could account for the "how Sandy did this' question.
