Whats that slick?
When good growth conditions exist, blooms of a simple floating algae called Trichodesmium are often confused with oil and coral spawn slicks. Blooms can be easily identified by their rusty brown colour as they occur in wind rows along the surface of the water. Slicks of coral spawn generally do not last more than two days after coral spawning. Any oil spill should be immeditely reportd to the local maritime authority.
