========================================
Description of files
DataTable.xlsx --> contains information related to the collection sites, plastic characteristics, and organism/surface microtexture presence-absence data decribed in the PLOS ONE manuscript.
.tif files --> scanning electron microscopy images of marine plastic debris (N = 1143 images). The first number of the file name is the identification number of the plastic imaged (N = 68 pieces; see 1st column of DataTable.xls).
.txt files --> Polymer type as estimated by Perkin-Elmer ATR of Polymers Library (N = 66).
