Comparison of the mean spectra of plastic litter in clear water with analogous dry spectra from33 and36 shown with dashed lines and asterisks, for (a) PET, (b) HDPE, (c) LDPE, and (d) PP. The red-ordered triples represent the SAM scores between the new and previously published spectra across the entire spectrum, VNIR, and SWIR regions, respectively.
