A primary topic of interest in the field of biological oceanography is the role of planktonic productivity in the global carbon cycle. Over the past 20+ years, the traditional food web of algal production, zooplanktonic consumers and higher trophic level predators has been undergoing revision with a stronger understanding of the contributions made within the microbial loop. Of particular interest has been mixotrophy, the blurring of trophic mode assignments within the microbial eukaryotes.

The overall goal of this cruise was to obtain a snapshot of the prevalence of mixotrophy within the Gulf of Maine and the potential contributions of mixotrophs to copepod diets. We proposed to accomplish this goal by sampling water and zooplankton from 3 stations.
