Parallel features off the coast of NC. A distinct edge can be seen of what looks like a submerged, Carolina bay. The area within this 'bay feature' contains parallel features that seem to be equidistance apart.

-Actually, this is a very common sight near an active inlet. The discoloration you see is called a "plume" and is actually being created by water exiting the Carolina Beach Inlet on the falling tide. Scroll a little farther south to the mouth of the Cape Fear River and you'll notice the same thing happening there.
