This is very interesting.....to me, anyway

Saharan Dust blows across the Atlantic, through the Bahamas each year,  never gave it much thought, though it would coat everything at times.
Here is report from Brian Kakuk, the underwater cave explorer and mixed gas diver on Abaco.
Abaco has spectacular underwater cave system and Kakuk has been exploring and mapping them for many years.
Cave diving never appealed to me after working in hazardous underwater oilfield locations around the world.
