Particulate hydrocarbons for mesocosm incubations

This dataset contains particulate hydrocarbon information from the two mesocosm experiments in June and August, 2011. Two independent mesocosm experiments were carried out in June and August of 2011 at the Dauphin Island Sea Lab as previously described. Briefly, 200 L barrels were lined with Teflon bags and placed in 2000 L tanks with circulating water. Water was pumped into each mesocosm through an intake tube with a 6.35 mm screen from south of Dauphin Island 6 h (June) or 24 h (August) before the start of the experiments to coincide with high tide. Treatments were randomly assigned to each mesocosm, with each treatment present in each of the five 2000 L tanks. In each experiment, there were 4 treatments, with 5 replicates each (20 barrels in total). These data present the changes in particulate hydrocarbons over the incubation period (10 days in June and 7 days in August). Mesocosm experimental design is described in Ortmann et al (2012) Dispersed Oil Disrupts Microbial Pathways in Pelagic Food Webs, PLos ONE, 7(7) e42548. doi:10.1371/journal.pone.0042548.
