      Abstract: 
          Abundance of live organisms (per 0.25 m2 quadrat) found in oyster reefs sampled in the early fall 
          (September/October) and spring (April/May) from 2015 to 2016. Four embayments were sampled from Louisiana to 
          the Florida panhandle, with sites that were previously oiled or non-oiled after the Deep Water Horizon Oil 
          Spill. Within oiled and non-oiled sites, oyster quadrat samples were taken from intertidal (along the marsh 
          edge) and subtidal areas, and also from mesohaline and high salinity sites. The top 10 cm of material was 
          collected from the quadrats and returned to the lab for enumeration of species.
      Purpose: 
          The purpose of this dataset is to describe the condition of oyster reef communities in areas with documented 
          exposure to oil from the Deepwater Horizon Oil Spill in 2010, as well as control sites (no documented oil 
          exposure). This field sampling, and the associated genetic analyses resulting from field collection of 
          oysters, will help determine the recovery trajectories in genetic, taxonomic, and functional diversity of 
          oyster reefs in the northern Gulf of Mexico, arising from oiling and response activities (e.g., freshwater 
          diversions, dispersants).

      Supplemental Information: 
          Year = the year of sampling Mo = the calendar month of sampling Day = the calendar day of sampling for any 
          given month Time_CST = the time the oyster reef site was sampled; in Central Standard Time Site = the ID 
          given to the sampled site; the first two letter correspond to the embayment Embayment = the generic sampling 
          embayment where the reef can be found; options (4) include: Mississippi Sound, Barataria Bay, Terrebonne 
          Bay, Florida Basin = location of the oyster reef within the generic sampling embayment: options (26) 
          include: Airport Marsh; Alabama Port; Apalachicola Bay; Barataria Bay, east; Barataria Bay, north; Bay 
          Junop, north; Bay Junop, south; Caillou Lake, north; Coffee Island; Dauphin Island; Dauphin Island Bay; DI 
          Shoals, northwest; East Bay Panama City; East Bay Pensacola; Escambia Bay, Pensacola; Grand Isle; Grand 
          Terre; Hackberry Bay; Heron Bay; Little Dauphin Island; North Bay Panama City; Pensacola Bay, west; 
          Portersville Bay; Terrebonne Bay, north; Terrebonne Bay, west; West Bay Panama City State = the US state 
          where the oyster reef site is located; options (3) include: Louisiana, Alabama, Florida Lat = latitude of 
          oyster reef site (WGS1984) (decimal degrees) Long = longitude of oyster reef site (WGS1984) (decimal 
          degrees) Near_Sub = the tidal regime for the site; options (2) include: nearshore (intertidal, along the 
          marsh edge) and subtidal OilingCat = the oiling category assigned to the site; based on categories assigned 
          by the Natural Resource Damage Assessment and Shoreline Cleanup and Assessment Technique (SCAT) maps for 
          non-NRDA sites; categories (2) include: oiled, not oiled SalinityCat = the salinity group assigned to the 
          oyster site, based on the measurement of salinity taken at the time of sampling in 2015; options (2) include 
          meso and high. For Barataria and Terrebonne Bays, high salinity is considered greater than or equal to 19 
          ppt. For Mississippi Sound, high salinity is considered to be greater than or equal to 21 ppt. The 
          difference in values is based on the differing salinity regimes in each embayment. WaterTemp_C = water 
          temperature just above the reef at the time of sampling; units are degrees Centigrade Salinity_ppt = 
          salinity just above the reef at the time of sampling; units are ppt (parts per thousand) DO_mgL = dissolved 
          oxygen just above the reef at the time of sampling; reading was taken as close to the oyster reef as 
          possible (surface for intertidal and just above the reef for subtidal reefs); units are mg per L QuadratRep 
          = the quadrat number at the site; a total of 3 quadrats were sampled at each oyster reef site; options (3) 
          include: Q1, Q2, Q3 SampleID = the ID for the quadrat sample taken at the oyster reef; this ID has the 
          format Site-QuadratRep; for example: MS01-Q1 is quadrat 1 from oyster reef number 01 in Mississippi Sound 
          BagMass_kg = the mass of the oyster reef sample collected and placed in a small-mesh bag; bags were measured 
          with a spring scale at the laboratory and the units are kg ProcessTime_CST = the time the oyster reef sample 
          was removed from the collection bag and placed on the table to begin enumerating species and measuring 
          oyster shell heights. This time is typically later in the day on the same day of collection, unless 
          processing extended past midnight. Time is recorded in Central Standard Time *The remaining columns are 
          counts of taxa (species, families, etc). Each is in a group of 3 – each species has one column for the 
          number of that species counted, one column for the multiplier (in case the quadrat was sub-sampled), and the 
          third column is the product of the first times the second and gives the density of each particular species 
          within the 0.25 m-squared quadrat. OysterSpat_Num = the number of live oyster spat counted in the 0.25 
          m-squared quadrat sample. Oyster spat is defined as oysters with shell heights less than or equal to 25 mm. 
          OysterSpat_Mult = the multiplier assigned in case the 0.25 m-squared sample was so large that it was 
          sub-sampled. Options (2) include: 1 or 4. 1 means the taxa was counted in the entire 0.25 m-squared quadrat 
          sample; 4 means that the 0.25 m-squared quadrat was divided into 4ths for processing and the previous column 
          will need to be multiplied by 4 in order to calculate a density per 0.25 m-squared area. 
          OysterSpat_Per0.25m2 = density of spat-sized oysters in 0.25 m-squared quadrat OysterSeed_Num = the number 
          of live oyster seed counted in the 0.25 m-squared quadrat sample. Oyster seed is defined as oysters with 
          shell heights greater than 25 mm and less than 75 mm. OysterSeed_Mult = *Can copy from any column ending in 
          “Mult”* the multiplier assigned in case the 0.25 m-squared sample was so large that it was sub-sampled. 
          Options (2) include: 1 or 4. 1 means the taxa was counted in the entire 0.25 m-squared quadrat sample; 4 
          means that the 0.25 m-squared quadrat was divided into 4ths for processing and the previous column will need 
          to be multiplied by 4 in order to calculate a density per 0.25 m-squared area. OysterSeed_Per0.25m2 = 
          density of seed-sized oysters in 0.25 m-squared quadrat OysterMarket_Num = the number of live market-sized 
          oysters counted in the 0.25 m-squared quadrat sample. Market oysters are those with shell heights great than
