DEVELOPMENT AND APPLICATION OF A FLUORESCENT MARKING TECHNIQUE FOR TRACING SAND MOVEMENTS ON BEACHES.

Abstract

Fluorescent dyes offer the advantages of low cost, rapid application, ready identification, and complete safety. In this study anthracene was used to mark beach sediment because it is brilliantly fluorescent, readily available, and easy to apply. A surface film of the dye proved satisfactory for short-term studies. The technique was tested in the intertidal zone of a beach on the west side of Sandy Hook, New Jersey. Dispersion of marked sediment was checked after dark with a portable ultraviolet lamp and samples were collected for quantitative analysis. Both markingg and analysis were done in the laboratory, but the technique is suitable for field use. Although fluorescent tracer techniques are still in the developmental stage, they promise to become a useful tool in coastal studies. (Author)
