Florida Keys, U.S.A. November 1990. The Florida Keys, a line of narrow, low
islands that begins at Key Largo extend in a gently curving, southwesterly arc
along U. S. Highway 1 to Key West. Visible in this photograph are keys from Big
Pine Key (near bottom center) to Sugarloaf Key (top center). Atlantic Ocean and
Gulf of Mexico tides cut numerous channels through the coral and granular
limestone sand (oolite) to create the islands (keys), which have thick growths
of mangrove (darker areas) and many bays. The sediment plumes appear to be
moving northwesterly into the Gulf of Mexico from the southeast (Atlantic
Ocean). Because of the clarity of water throughout the region, water depth can
be determined by different shades of blue—deeper water is darker and shallow
water is lighter. In many instances these colors can represent differences in
depth of tens to hundreds of feet (NASA).
