      Abstract: 
          Testing the effect of WAF (Water accommodated fraction) on TEP (transparent exopolymers) and marine snow 
          formation. TEP was measured over time in the Control and WAF treatments and marine snow formation monitored.
      Purpose: 
          This first mesocosm experiment was a test of the general design and approach for following mesocosm 
          experiments. It was also conducted to investigate the response of a natural plankton community to dispersed 
          oil in comparison to conditions without oil. Specifically, the effect of oil addition to a coastal community 
          for the production of transparent exopolymer particles (TEP) was tested.

          Description: 
              Dataset contains laboratory measurements of TEP as a function of WAF. The seawater used was collected on 
              July 30, 2015, 8 kilometers off-shore south of Galveston (TX) in the Gulf of Mexico.
      Supplemental Information: 
          Sampling day (number) SSW = surrounding seawater, sample does not include marine snow; Avg = average (of three 
          replicate mesocosms); Stdev = standard deviation; TEP = Transparent Exopolymer Particles (ug GX eq/L); GXeq 
          = Gum Xanthan equivalent; Control = Control treatment containing seawater and plankton community; WAF = 
          Water accommodated fraction treatment, containing WAF made from the seawater (see methods) and plankton 
          community|In order to create an environment for controlled testing of TEP formation two mesocosms consisting 
          of 96 L glass tanks were used. The WAF (water accommodated fraction of oil) for this experiment was produced 
          using 130 liter baffled recirculating tanks (BRT) and Macondo Surrogate oil. The seawater used was collected 
          on July 30, 2015, 8 kilometers off-shore south of Galveston (TX) in the Gulf of Mexico. The seawater (34 
          ppt) was processed through a charcoal filter to remove large particulates and debris. The control tank was 
          filled with 79 liters of this seawater. This seawater was also used to fill the 130 L baffled recirculating 
          tank to generate WAF. The WAF was prepared by mixing a total of 24 ml (2 ml to start, 2 mL after 1 hr, then 
          5 ml at ~ 2, 3, 4 and 5 hrs) of Macondo Surrogate oil into 130 L of the seawater. Total mixing time from the 
          start of oil addition to transfer to the mesocosms was 18 hrs. The WAF (79 L) was transferred to a tank and 
          homogenized. Plankton (≥63 µm) samples were collected at the Galveston pier using a net and transferred into 
          polycarbonate bottles. This concentrated plankton sample was introduced to each mesocosm and stirred (2 L to 
          each tank for a final volume 81 L) immediately prior to starting the experiments. Banks of lights were 
          placed behind each of the glass mesocosm tanks and a 12:12 light/dark cycle employed. Both mesocosms were 
          sampled daily and TEP measured. Note: TEP could not be sampled in two other mesocosms, which contained 
          Corexit, as Corexit interferes with the method. TEP concentrations were determined in triplicate using the 
          colorimetric method and are expressed in Gum Xanthan equivalents (GXeq.) (Passow and Alldredge, 
          1995).|||Coefficient of variation (standard deviation / average) were calculated from the triplicate TEP 
          analysis.|Passow, U., Alldredge, A.L., 1995. A dye-binding assay for the spectrophotometric measurement of
