What happens underwater during a hurricane?

Some studies conducted in the Caribbean Sea have shown that in the year following a hurricane, coral cover is reduced by 15-20% (more or less, depending on the intensity of the hurricane) in the affected areas. There are several factors that go into the negative effect on coral: 1) the turbulent water breaks it, 2) the days of muddied water reduces the amount of sunlight reaching the algae in coral tissue, 3) the fine suspended particles clog the pores, and 4) the tremendous amount of rain reduces the salinity of the shallow ocean in the immediate area which can stress coral.
