      Abstract: 
          This dataset covers part of the data for experiments in which a single PAH was added to mesocosms. Data 
          provided here are experimental design, bioturbator data (including survival/recovery) and environmental data 
          (D.O., redox, turbidity, etc.) for sediment and water in the mesocosms. Data on PAH levels in water and 
          sediment will be provided in a separate dataset.
      Purpose: 
          Experiment aimed at determining the effect of bioturbators on the distribution and degradation of petroleum 
          hydrocarbons in nearshore environments. This specific dataset provides data on experimental design and 
          bioturbator information (as background information) and data on environmental variables measured in the 
          mesocosms. The environmental data are meant to provide insights on how the bioturbators may be affecting the 
          distribution and biodegradation of the hydrocarbons.

          Description: 
              Dataset contains laboratory measurements. Field sampling is limited to collection of sediment and test 
              species. Clams and associated sediment were collected 9/27/14 from Choctoawhachee Bay, FL (30.38854 N, 
              -86.17429 W). Shrimp and associated sediments were collected 10/26/14 from Bay St. Louis, MS (30.25658 
              N, -89.41510 W).
      Supplemental Information: 
          Experimental design worksheet includes details on when the experiment was conducted, when sampling was 
          conducted (for environmental variables and petroleum hydrocarbons) and what tanks received which of 4 
          treatments (bioturbator present/absent * pyrene added or not). Bioturbator worksheet has info on bioturbator 
          identity/source/experimental density, recap of treatment assignments to specific tanks, and listing of the 
          number of bioturbators recovered at the end of the experiment. Clam size (cm) and % survival are also 
          included. Turbidity worksheet has turbidity results (in NTU) by observation day and tank. Redox worksheet 
          has redox measurement results (in mV), 3 replicate measurements and mean, by observation day and tank. D.O. 
          worksheet has ODO measurement results (in % saturation and mg/L D.O.) and probe-adjusted data (since 
          measurements were conducted with separate probes, in clean tanks and pyrene-dosed tanks, to avoid 
          cross-contamination). The same worksheet has daily results from measurements on a single sample using both 
          probes - for establishing probe corrections). ODO measurements are listed by observation day and tank. 
          Temperature worksheet has measurements for water temperature (in *C; duplicate measurements and means), 
          measurements for sediment temperature (in *C; duplicate measurements and means), the difference in 
          temperature between water and sediment of the same tank (Delta T in °C), and the absolute temperature 
          difference (Delta T abs in °C). Temperature data are listed by observation day and tank. |Water samples of 
          approximately 30 mL were collected from the tanks (at approximately mid-depth of the water column) using a 
          turkey baster and placed in 30-mL glass tubes for transport to the lab. In the lab, water samples were 
          transferred to glass tubes and turbidity quantified on a Hach 2100A turbidimeter, calibrated daily with 
          GELEX® secondary turbidity standards. Turbidity was expressed in nephelometric turbidity units (NTU). Redox 
          measurements were obtained with a custom made redox electrode with a platinum indicator electrode exposed at 
          the end of a thin rigid shaft and a Corning calomel reference probe, using a portable pH/volt meter (Cole 
          Parmer Digi-Sense® pH/mV/Temp). The bottom half of the reference electrode was placed in the water column, 
          while the indicator electrode was pushed into the sediment such that its exposed platinum end was at 
          mid-depth of the sediment. Mid-depth values were determined at 3 locations in each tank. Redox readings were 
          allowed to stabilize (“stable” if no change within 5 seconds) prior to recording a redox value. Dissolved 
          oxygen (D.O.) measurements were obtained with the YSI ProODO meter. Optical D.O. readings were taken at the 
          middle of the water column depth in each tank, and D.O. recorded in “% saturation” and “mg/L O2”. Different 
          probes were used for clean tanks and tanks to which petroleum hydrocarbons were added. The correct for 
          differences between the probes, measurements were taken with both probes on a single water sample each day 
          that water quality measurements were done. Probe-adjusted ODO values were calculated on the basis of the 
          average differences between the two probes for these water samples. Temperature measurements were obtained 
          with a Fisher Scientific NiCr/NiAl T/C type K probe (0.1 °C resolution) with the Traceable® type K meter. On 
          each tank, two measurements were taken in the middle of the water column and two measurements were taken at 
          mid-depth of the sediment. Different probes were used for clean tanks and those to which petroleum 
          hydrocarbons were added. Since the goal was to quantify differences between the sediment and the water 
          column within tanks (obtained with the same probe), no corrections were needed for between-probe 
          differences.|Instrumentation information is provided in the methods section.|The experiment lasted 10 days. 
          Environmental samples were taken on 6 days during the 10-day period; 3 samples during mornings and 3 samples 
          during afternoons (in order to capture some of the within-day variability).|Instruments were calibrated 
          prior to use. Data entry into digital files was duplicated.|Dataset R2.x226.000:0003 will contain the 
          results from the hydrocarbon analyses of the sediment and water samples from these experiments.
