Saharan dust is key to formation of Bahamas’ Great Bank, study finds

24 julio 2014

Saharan dust played a major role in the formation of the Bahamas islands, a new study suggests. Researchers showed that iron-rich Saharan dust provides the nutrients necessary for specialized bacteria to produce the island chain’s carbonate-based foundation. Persistent winds across Africa’s 3.5-million square mile Sahara Desert lifts mineral-rich sand into the atmosphere where it travels the nearly 5,000-mile northwest journey towards the U.S. and Caribbean.
