Composition of microplastic in a subset of the eastern North Pacific

Figshare 2013
Goldstein Miriam

Summary

This dataset describes the polymer composition of microplastic particles collected from three water masses in the eastern North Pacific Ocean: the California Current, an intermediate region, and the North Pacific Subtropical Gyre. The main polymers identified were LDPE, HDPE, PP, PS, and unknown polyethylene.

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.
