Box plots of non-seep and seep locations Gulf of Mexico sites compared to DWH blowout conditions. (A) Methane concentration (mol L^–1), (B) methane oxidation rate (mol L^–1 d^–1), and (C) rate constant (d^–1). The line within the box is the median, and the boundary of the boxes indicates the 25^th and 75^th percentiles. Error bars above and below indicate the 90^th and 10^th percentiles. Filled circles represent outliers. N values are (non-seep and seep) 22 and 20 for 2001; 11 and 76 for 2011; 56 and 32 for 2012; 101 and 90 for 2013; 45 and 116 for 2014; 68 and 61 for 2015; 17 for mud volcano conditions at GB425 in 2006; and 81 for blowout conditions in 2010. The 2010 blowout box includes all data from all sites (non-seep and seep) during the blowout year, as reported by Crespo-Medina et al. (2014). Dashed line separates background conditions prior to the DWH blowout. Note the log scale for A and B. DOI: https://doi.org/10.1525/elementa.332.f4
