Composition of microplastic in a subset of the eastern North Pacific

Composition of microplastic in the a) California Current (N=52), b) intermediate region (N=72), and c) NPSG (N=433). Abbreviations are as follows: low-density polyethylene (LDPE), high- density polyethylene (HDPE), polypropylene (PP), polystyrene (PS), and unknown polyethylene (unknown PE). Note that water masses should be viewed as highly approximate, since they were estimated using surface trace data only.

This is Figure 3.4. in the Goldstein 2012 dissertation.
