      Abstract: 
          Samples were collected from coastal mesocosm studies to assess the response of the planktonic community to 
          exposure to oil and Corexit. This dataset includes the location of 12 RNA sequencing samples for eukaryotic 
          plankton for the ADDOMEx mesocosm experiment, Coastal water with coastal microbial concentrate, COAST 
          (mesocosm 2). This dataset also includes the SraRunTable (biosample accession SAMN09981213) at 
          https://www.ncbi.nlm.nih.gov/biosample/9981213 for these data.
      Purpose: 
          RNA was extracted from samples at the end of the mesocosm experiment to enable analysis of eukaryotic 
          community structure and relative transcript abundance in response to oil (WAF; water accommodated fraction) 
          and Corexit enhanced WAF (CEWAF and dilute CEWAF; chemically enhanced water accommodated fraction) treatments.

          The seawater was collected from the same location as that used in TeCOAST mesocosm but was collected on 
          October 17 2015, from 8 kilometers offshore south of Galveston, Texas in the Gulf of Mexico. The salinity 
          was 31. The seawater was processed through a charcoal filter to remove large particles and debris. Four 
          treatments were prepared in triplicate. Control tanks were filled with seawater and a plankton mixture. 
          Water accommodated fraction (WAF) of oil was prepared by mixing 25 mL (5 ml ~ every 30 min for 2.5 hrs) of 
          Macondo surrogate oil into 130 L of seawater then mixing for 12 to 24 hrs. The WAF was then introduced into 
          the WAF mesocosm tanks and filled to 87 L and mixed. From these WAF tanks, 6 L was removed for other 
          experiments and analyses (2L for roller tables, 2 L dark/light, 4 L hydrocarbon analyses). In order to make 
          chemically enhanced water accommodated fraction (CEWAF), Corexit was mixed with oil in a ratio of 1:20 and 
          25 mL of this mixture (5 ml every 30 min for 2.5 hrs) of surrogate oil plus Corexit was added to 130 L of 
          seawater which was mixed for 8 to 24 hrs prior to being transferred to the mesocosm tanks. The CEWAF was 
          then introduced into the CEWAF mesocosm tanks and filled to 96 L and mixed. From these CEWAF tanks, 15 L was 
          removed for other experiments and analyses (9 L for the DCEWAF mesocosms, 2L for roller tables, 2 L 
          dark/light, 4 L hydrocarbon analyses). Diluted CEWAF (DCEWAF) was prepared by mixing 9 L of CEWAF with 78 L 
          of the original seawater for a total volume of 87 L. From these DCEWAF tanks 6 L was removed for other 
          experiments and analyses (2L for roller tables, 2 L dark/light, 4 L hydrocarbon analyses). Plankton (≥63 µm) 
          were collected using a net and transferred into polycarbonate bottles. This concentrated plankton mass was 
          introduced to the tanks and stirred (2 L to each final volume 83 L) immediately prior to starting the 
          experiments. The EOE mean concentration of the three mesocosms for the control, WAF, DCEWAF and CEWAF at the 
          start of the experiments were 0 mg/L, 0.26 mg/L, 2.74 mg/L and 41.5 mg/L, respectively. The EOE mean 
          concentration of the three for the control, WAF, DCEWAF and CEWAF mesocosms after 72 hours were 0 mg/L, 0.06 
          mg/L, 1.03, and 17.3 mg/L, respectively.
          
          Estimated Oil Equivalence (EOE)
          The estimated oil equivalents (EOE) were determined by fluorescence (Wade et al. 2011) using Macondo surrogate 
          oil as a standard to produce calibration curves at 5 to 7 concentrations. Water samples (5 to 20 ml) were 
          extracted with 5 ml of dichloromethane. An aliquot of the extract was placed in a cuvette for fluorescence 
          analyses (Horiba Scientific Aqualog Fluorometer). The EOE were determined from the calibration curve (Wade 
          et al. 2011). Samples with fluorescence responses that exceeded the calibration curve were diluted so that 
          their fluorescence was within the calibration range. Samples were taken at the beginning and end of the 
          experiment and at intervals in between and at the same time point as measurements of other parameters during 
          the experiment.
          
          Eukaryotic metatranscriptome sampling and analysis
          Samples were taken for RNA extraction and sequencing at time t = 72 h from each replicate and treatment (3 
          replicates x 4 treatments = 12 samples). Filters were immediately frozen at –80°C. RNA extraction was 
          performed using standard protocols. Sequencing was performed on an Illumina HiSeq 2000 at the McGill 
          University Genome Quebec Innovation Centre (http://gqinnovationcenter.com/index.aspx) using the TruSeq mRNA 
          stranded mRNA protocols. Raw reads from the sequencing pipeline were deposited in the NCBI SRA,
