Condition Of Larval Spanish Mackerel Scomberomorus Maculatus In Relation To The Deepwater Horizon Oil Spill, John Timothy Ransom, J.E. Filbrun, Frank J. Hernandez Jr.
Condition Of Larval Spanish Mackerel Scomberomorus Maculatus In Relation To The Deepwater Horizon Oil Spill, John Timothy Ransom, J.E. Filbrun, Frank J. Hernandez Jr.
Faculty Publications
The Deepwater Horizon oil spill (DWHOS) coincided with the pelagic larval stages of many valued commercial and recreational fishes in the northern Gulf of Mexico. Larval fish survival and eventual recruitment into adult populations may have been impacted directly through toxicity or indirectly through changes in the planktonic food web caused by the release of oil and chemical dispersants during the DWHOS event. Using samples from a long-term ichthyoplankton survey off the coast of Alabama, USA, in a region impacted by the DWHOS, the abundance and condition of larval Spanish mackerel Scomberomorus maculatus were compared during summer months in years …
Condition Of Larval Red Snapper (Lutjanus Campechanus) Relative To Environmental Variability And The Deepwater Horizon Oil Spill, Frank J. Hernandez Jr., J.E. Filbrun, J. Fang, John Timothy Ransom
Condition Of Larval Red Snapper (Lutjanus Campechanus) Relative To Environmental Variability And The Deepwater Horizon Oil Spill, Frank J. Hernandez Jr., J.E. Filbrun, J. Fang, John Timothy Ransom
Faculty Publications
The Deepwater Horizon oil spill(DWHOS)spatially and temporally overlapped with the spawning of many fish species, including Red Snapper, one of the most economically important reef fish in the Gulf of Mexico. To investigate potential impacts of the DWHOS on larval Red Snapper, data from a long-term ichthyoplankton survey off the coast of Alabama were used to examine: (1)larval abundances among pre-impact (2007–2009), impact(2010), and post-impact (2011, 2013) periods; (2) proxies for larval condition (size-adjusted morphometric relationships and dry weight) among the same periods; and (3) the effects of background environmental variation on larval condition. We found that larval Red Snapper …
Pah Analysis: Muscle And Liver Pah Concentrations In Longline Captured Fish, Northern Gulf Of Mexico, 2011-2013, Steven Murawski
Pah Analysis: Muscle And Liver Pah Concentrations In Longline Captured Fish, Northern Gulf Of Mexico, 2011-2013, Steven Murawski
C-IMAGE data
The data contained in the two spreadsheets in this dataset represent biliary PAH metabolite concentrations from selected species collected in the northern Gulf of Mexico (NGOM) during longline sampling. The 2011 data were analyzed at the Northwest Fisheries Science Center (NWFSC). All data from 2012 on were analyzed at Mote Marine Laboratory (MML). Sample collection and methods are described in Snyder et al. 2015, PAH-exposure in Gulf of Mexico Demersal Fishes, Post-Deepwater Horizon. Environmental Science and Technology, DOI 10.1021/acs.est.5b01870.
Changes In Sediment Redox Conditions Following The Bp Dwh Blowout Event, D. W. Hastings, Patrick Schwing, G. R. Brooks, R. A. Larson, J. L. Morford, T. Roeder, K. A. Quinn, T. Bartlett, Isabel C. Romero, David Hollander

Following the blowout of the Macondo well, a pulse in sedimentation resulted in changes in sedimentary redox conditions. This is demonstrated by downcore and temporal changes in the concentration of redox sensitive metals: Mn, Re, and Cd. Sediment cores collected in the NE Gulf of Mexico (GoM) reveal increased sedimentation after the Deepwater Horizon (DWH) blowout. The formation of mucous-rich marine snow in surface waters and subsequent rapid deposition to underlying sediments is the likely cause. Respiration of this material resulted in decreased pore-water oxygen concentration and a shoaled redoxcline, resulting in two distinct Mn peaks in sediments following …
Associations Of Metal Exposure In Otoliths With Lesion Formation In Offshore, Northeastern Gulf Of Mexico Fishes Collected After The Deepwater Horizon Oil Spill (2011-2013), Ernst B. Peebles
C-IMAGE data
This dataset contains annual metal concentrations for the years 2009-2011 within the otoliths of six, offshore Gulf of Mexico fishes: Red Grouper, Epinephelus morio; Red Porgy, Pagrus pagrus; Red Snapper, Lutjanus campechanus; Southern Hake, Urophycis floridana; Tilefish, Lopholatilus chamaeleonticeps; and Yellowedge Grouper, Hyporthodus flavolimbatus. Fish were collected from the northeastern Gulf of Mexico, from approximately the Louisiana Shelf to the West Florida Shelf. For each sample, a suite of 9 isotopes was measured within fish otoliths: 24Mg, 51V, 53Cr, 57Fe, 59Co, 60Ni, 63Cu, 64Zn, and 208Pb. Annual metal concentrations were determined by averaging metal concentrations corresponding to the annual increment …

The recent oil spill in the Gulf of Mexico had significant effects on microbial communities in the Gulf, but impacts on nitrifying communities in adjacent salt marshes have not been investigated. We studied persistent effects of oil on ammonia-oxidizing archaeal (AOA) and bacterial (AOB) communities and their relationship to nitrification rates and soil properties in Louisiana marshes impacted by the Deepwater Horizon oil spill. Soils were collected at oiled and unoiled sites from Louisiana coastal marshes in July 2012, 2 years after the spill, and analyzed for community differences based on ammonia monooxygenase genes (amoA).
