Submesoscale variation in microplastic, zooplankton, and plastic to plankton ratio

Submesoscale variation in microplastic, zooplankton, and plastic to plankton ratio A) Microplastic numerical concentration (No. m-2); B) Microplastic mass concentration (mg m-2) ; C) Zooplankton biomass concentration (mg m-2) ; D) Ratio of microplastic dry mass to zooplankton dry mass. Figure 2.5 in Goldstein 2012 dissertation.
