(A) Box plots of unadjusted erosion rates (m/yr) in each stem oiling category for all sites. (B) Mean excess erosion (m/yr) for each stem oiling category. Excess erosion is the difference between the observed mean erosion for that stem oiling category and the expected mean wave-adjusted erosion rate if there were no differences in erosion among the stem oiling categories. The vertical lines are the central 95% randomization distributions for excess erosion in each stem oiling category. When the vertical line does not cross 0, the p-value for the comparison of that stem oiling category to the overall erosion rate is less than 0.05. (C) Mean excess erosion (m/yr) by stem oiling category in 2011–2012 and 2012–2013 for all sites. Symbols as in Fig. 2B. (D) Box plot comparing total belowground biomass between the 0% and 90.1–100% oiling categories in CWV plots nearest to the marsh edge in Fall 2010.
