Biogenic films at the mouth of the Suez Canal : Astronauts aboard the Space Shuttle Discovery in August 2001 used the sunglint off the surface of the Mediterranean Sea to reveal biogenic films on the ocean surface. The films dampen surface capillary waves, creating brighter and darker reflections, which, in turn, trace the complex surface water movements along the coast. The sunglint also highlights coastal features (jetties, submerged coastal areas) near the Port of Suez.
