Visible reflectance characteristics of marine debris in the sandy beach

Abstract

Abstract Marine debris has become a global thread to the coastal and marine areas, and the major causes for the decrease in the quality of aquatic environment. The study was aimed to document the spectral features of several types of marine debris based on criteria and developing spectral libraries which can distinguish between debris and substrate where the marine debris location is found. The marine debris data was collected from the coast of Makassar City, South Sulawesi. The spectral sample was measured using a 4000 A spectroradiometer that works on a wavelength spectrum 340 - 1040 nm. The results showed that the identification of marine debris on the optimal sandy beach can be done at 480-620 nm wavelength.
