This fileset provides data and SEM images described in: Reisser J, Shaw J, Hallegraeff G, Proietti M, Barnes DKA, Thums M, Wilcox C, Hardesty BD, Pattiaratchi (2014) Millimeter-sized Marine Plastics: A New Pelagic Habitat for Microorganisms and Invertebrates. PLOS ONE If you have any question/comment, please contact us at [e-mail] ======================================== 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). ======================================== Description of the variables/columns of DataTable.xlsx # -> plastic identification number. Goes from 1 untill 68. Type -> type of plastic. Hard (rigid fragment), Soft (flexible fragment), Pellet (raw material used to make plastic objects - see http://www.pelletwatch.org), Styro (expanded polystyrene/Styrofoam fragment). Polymer -> polymer the plastic piece is made of. PE (polyethylene), PP (polypropylene), PS (polystyrene). Length -> plastic length, in millimeters. Measured using ImageJ. Solidity -> plastic solidity index. Measured using ImageJ. Area -> plastic area, in squared millimeters. Measured using ImageJ. Perimeter -> plastic perimeter, in millimeters. Measured using ImageJ. Circularity -> plastic circularity index. Measured using ImageJ AspectRatio -> plastic aspect ratio. Measured using ImageJ. Roundness -> plastic roundness index. Measured using ImageJ. LinearFracture -> presence/absence of linear fracture on the plastic. 1=present, 0=absent. ConchoidalFracture -> presence/absence of conchoidal fracture on the plastic. 1=present, 0=absent. Pit -> presence/absence of pit on the plastic. 1=present, 0=absent. Groove -> presence/absence of groove on the plastic. 1=present, 0=absent. Diatom -> presence/absence of diatom on the plastic. 1=present, 0=absent. Coccolith -> presence/absence of coccolith on the plastic. 1=present, 0=absent. Dinoflagellate -> presence/absence of dinoflagellate on the plastic. 1=present, 0=absent. Round<1micron -> presence/absence of rounded cell smaller than 1 micrometer on the plastic. 1=present, 0=absent.

Bryo -> presence/absence of bryozoan on the plastic. 1=present, 0=absent. Lepas -> presence/absence of Lepas on the plastic. 1=present, 0=absent. Isopod -> presence/absence of isopod on the plastic. 1=present, 0=absent. Egg -> presence/absence of egg on the plastic. 1=present, 0=absent. Worm -> presence/absence of worm on the plastic. 1=present, 0=absent. Region -> marine region where the plastic was collected. North West, South West, South East, Temperate East, Coral Sea, and Pacific (see Figure 1 of the paper). Date -> date (day.month.year) when the plastic was collected. SeaTemperature -> Sea surface water temperature (in degrees celsius) of the plastic collection site. Salinity -> Sea surface salinity of the plastic collection site. Latitute -> latitude (in degrees) of the plastic collection site. Longitude -> longitude (in degrees) of the plastic collection site. ========================================
