Saharan dust storms may be a factor in Caribbean reef health
By Summit Voice
SUMMIT COUNTY — Coral reefs in the Caribbean have declined much faster than their counterparts in the Indo-Pacific region, and scientists know think they know at least part of the reason — seaweed.
Seaweed grows much more prolifically in the Caribbean, possibly because of the iron-rich dusts that blow off the Sahara and are carried across the Atlantic by the Trade Winds.
Along with fending off the stresses of global warming, pollution and overfishing, the Caribbean reefs have to deal with more of the aquatic vegetation.
As a result, coral reefs in the Indo-Pacific region, including the Great Barrier Reef, recover faster from major stresses than their Caribbean counterparts. (more…)
