Saharan dust blown over Cape Verde Islands

From Africa's Sahara Desert, wind-blown dust billows out over the Atlantic Ocean. Dust transport over the ocean deposits iron-rich dust onto the ocean, where it supports ocean-based plant life. The dust is both a blessing and a curse, however, as some scientists have begun to show that fungal pathogens in the dust are contributing to the ailing health of Caribbean coral reefs.
