Plankton [sup 13C/[sup 12C] variations in Monterey Bay, California: evidence of non-diffusive inorganic carbon uptake by phytoplankton in an upwelling environment.

Presents a study which found that the fractionation of a photosynthetic carbon is affected by variations in diffusive transport of carbon dioxide into phytoplankton cells in Monterey Bay, California. Implications of variation in C fractionation in plankton; Methods and results; Discussion.
