MeHg concentrations and stable isotope ratios for individual samples from mercury reduction experiments conducted on marine phytoplankton from 2012-2013 (NCEI Accession 0291497)

This dataset contains chemical and physical data collectedat Antarctic Peninsula from 2012-12-12 to 2013-08-27. These data include Mercury cation. These data were collected by Kritee Kritee of Environmental Defense Fund, John Reinfelder of Rutgers University, Nicholas S. Fisher of Stony Brook University - SoMAS, Robert Mason of University of Connecticut, and Joel D. Blum of University of Michigan as part of the "Collaborative Research: Transformations and mercury isotopic fractionation of methylmercury by marine phytoplankton (Phytoplankton MeHg)" project. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2020-10-20.

Acquisition Description:
For detailed methods, see Kritee, et al. (2017).

Rates and Hg stable isotope signatures of photomicrobial transformations of Hg(II) and MeHg in marine phytoplankton exposed to visible light and varying levels of UV radiation were examined in experiments with (1) sterile-filtered spent growth media containing extracellular exudates from cultures of Isochrysis galbana , a eukaryotic marine microalga of the globally important Prymnesiophyceae class; (2) actively growing monospecific cultures of I. galbana ; and (3) cysteine or ocean water washed (nongrowing) I. galbana cells.

These data were published in Supplementary Table 4 of Kritee, et al. (2017).
