That deep blue abyss is the Tongue of the Ocean, a trench between Great Exuma
and Andros islands in the
Bahamas
. It's fringed by this crenelated structure: the
Great Bahama Bank, a huge rim of shoals made of ooids. An ooid? A tiny pearles-
cent, carbonate-coated sphere hugging a miniscule grain of sand or bit of shell.
Ooids shift with the tides. If you had a camera trained on this spot for 20 years,
you'd capture these underwater dunes rippling and billowing slightly, like curtains
breathed on by the wind.
