A shameless plug --

As a follow-up on Gene Shinn's comments about the dust hypothesis and its bearing on the blooms of floating seaweeds in the Caribbean, some of you may be interested in the vicious circle hypothesis for the lack of Caribbean reef resilience, which includes the dust hypothesis and is congruent with increasing floating seaweed abundance because of a combination of dissolved organic carbon inputs from major river systems and the cycling of dissolved organic carbon and nutrients between sponges and seaweeds.  For more, see:
