Experimental Sea Slicks in the Marsen (Maritime Remote Sensing) Exercise.
Abstract
Experimental slicks with various surface properties were generated in the North Sea as part of the MARSEN (Maritime Remote Sensing) exercise. The one-molecule-thick slicks, as large as 2.3 square kilometers in area, were formed from nontoxic, organic substances and allowed to drift through the area observed by sensors mounted on the research platform Nordsee. The slicks were also generated in coordination with overflights of aircraft equipped with remote sensing instrumentation. Because of the numerous effects of surface films on air-sea interfacial processes, these experiments were designed to enhance the understanding of energy exchange between wind and water and of the interactions between capillary and gravity waves. In addition, information was obtained on the influence of sea surface films on the interpretation of signals received by remote sensing systems. Criteria for the selection of film-forming material for experimental slicks and various techniques for slick generation are discussed. Physical processes modified by natural and man-made surface films are reviewed, along with the resulting impacts of such modifications of the air-water interface on remotely sensed signals. The characteristics of the MARSEN surface films will be described as well as preliminary results from the remote systems which sensed the slicks. (Author)
