Figures from Goldstein 2012 dissertation depicting microplastic in the North Pacific Subtropical Gyre

These are unpublished figures from my 2012 doctoral dissertation. They didn't find a place in the published manuscripts, but I thought they might be useful, so I am placing them here. Please see the dissertation, linked below, for further methodological details. If you refer to these figures, please cite the dissertation as follows: Goldstein, M.C. 2012. Abundance and ecological implications of microplastic debris in the North Pacific Subtropical Gyre. Ph.D. dissertation. Scripps Institution of Oceanography at the University of California San Diego, La Jolla, CA.
