        abstract:  This data package reports presence/absence and density data, and environmental data (temperature, salinity, dissolved oxygen) collected in the northern Gulf of Mexico during R/V Blazing Seven cruises LF2015A and LF2015B from 2015-06-06 to 2015-07-25. It also includes stable isotope ratios of model meso- and bathypelagic micronekton species of the Gulf of Mexico collected during cruises DP01, DP02, LF2015A and LF2015B from 2015-05-01 to 2015-08-21, and catch number of true tuna (Thunnus spp.) larvae collected in the Gulf of Mexico before (2007-2009), during (2010), and after (2011-2013; 2015) the Deepwater Horizon Oil Spill (DWHOS). Larval fishes sampled from 48 stations were collected with three different gear types: 1) neuston net (2 m width x 1 m height frame) rigged with 1200 micron mesh; 2) paired 61-cm bongo nets with 333 and 500-micron mesh; 3) paired ring net with 1000 micron mesh. Other cruise data were collected at each site including latitude/longitude, date, time, environmental data (temperature, salinity, dissolved oxygen) and Sargassum dry weight. Sea surface temperature, salinity, and dissolved oxygen were measured at the surface of each station using a Sonde 6920 Environmental Monitoring System (YSI Inc., Yellow Springs, Ohio, United States). Catch data are also being coupled with environmental data to identify high quality (highly suitable) habitat of each species or taxonomic group.
        purpose:  The purpose was to characterize larval fish assemblages in pelagic waters of the Gulf of Mexico and compare and estimate the life history and ecosystem parameters that favor the production and survival of pelagic fish larvae and juveniles multiple cohorts before before (2007-2009), during (2010), and after (2011-2013; 2015) the Deepwater Horizon Oil Spill (DWHOS). Habitat suitability models are being developed for tuna larvae from 2007-2015 collections that will ultimately be used to predict the probability of occurrence of Thunnus species in future years.

Sea surface temperature and salinity were measured at each station GPS location was recorded at each station. NA denotes three different situations 1) specific net was not used to collect larva, 2) environmental data missing, 3) stations where Thunnus larvae were not genetically identified. Larvae at each station were collected from 2007 to 2010 with two neuston nets (2 m width x 1 m height frame) with 500 and 1200 micron mesh, and with two different sampling gears from 2011 to 2015: 1) neuston net (2 m width x 1 m height frame) with 1200 micron mesh 2) a paired 61-cm bongo nets with 333 and 500 micron mesh. General Oceanics flow meters (Model 2030R, Miami, FL) were placed within net frames determine the volume of water sampled by each net. Tuna larvae were sorted to the genus level using a Leica MZ stereomicroscope, and Thunnus larvae were identified to the species level using a genotyping method (high-resolution melting analysis). From 2007 to 2009 due to a large number of Thunnus larvae in the samples, high resolution melting analysis (HRMA) was performed on larvae from a subset of positive stations (Thunnus larvae present). For stations examined with HRMA containing less than 100 Thunnus larvae, each individual was genetically identified to species. If more than 100 Thunnus larvae were present, 100 randomly selected larvae were genetically identified. An unlabeled probe (UP) HRMA assay was developed for Gulf of Mexico tuna species genetic identification..

                description:  Parameter or Variable: Sea surface height anomaly (measured); Units: cm; Observation Category: satellite; Sampling Instrument: AVISO altimeter; Sampling and Analyzing Method: Sea surface height anomaly (SSHA, cm) data were determined from remotely sensed data that matched the sampling dates and station locations. SSHA data were generated every 7 days from combined satellite altimetry measurements using Jason-1 and 2, ENVISAT/ERS- 1 and 2, Geosat Follow-On and Topex/Poseidon interlaced [Aviso (Archiving, Validation and Interpretation of Satellite Oceanographic data), www.aviso.oceanobs.com] and data consisted of averaged time periods with 0.25 resolution..
