Sees through murky water

Taking a deep breath, Clark plunged into the
water. The water below was murky, with sediment
creating an impenetrable wall making visibility almost
impossible.

Although his special vision allowed him to see
through it, the sand and accumulated sediment floating
in the water darkened everything, casting the area
around him in a perpetual twilight which was only
going to get worse when the sun set.

He could see the darkened mass of the ship half
buried in the sand. Three hundred feet down, with
three hundred feet of sand and water and other debris
between it and the sun, the ship was a pitiful sight.
