Comparison of sulfate reduction rates from this study with prior studies. Comparison of the estimated potential in situ areal sulfate reduction rates in the oil-amendment experiment from this study (yellow) to ex situ radiotracer measurements of sulfate reduction rates from other oily and non-oily environments. Comparison data derive from a previously published summary of rates from Gulf of Mexico (GoM) and other sediments (Bowles et al., 2011). DOI: https://doi.org/10.1525/elementa.129.f6
