(accepted with revisions, JGR-Biogeosciences) Increase in nutrients, mercury, and methylmercury as a consequence of elevated sulfate reduction to sulfide in experimental wetland mesocosms


3. Links to other publicly accessible locations of the data:Sites are registered with SESAR (System for Earth Sample Registration; http://www.geosamples.org) and have been assigned IGSNs (International Geo Sample Numbers); water, porewater, and sediment samples, and observations, from those sites have similarly been registered with IGSNs that are “children” of each site IGSN.  Site IGSNs are given in column A of Myrbo_MPCA_WRSS_mesocosm-synoptic-data.xlsx.
A subset of chemistry data is in the process of being submitted to the EarthChem database (http://www.earthchem.org/).

4. Was data derived from another source? no
