Short-Lived Radioisotope (Excess Pb210) Measurements From Sediment Cores Collected Throughout The Gulf Of Mexico From 2010-11-07 To 2017-07-20, Patrick Schwing, David Hollander
C-IMAGE data
This dataset includes baseline short-lived radioisotope measurements from sediment cores collected throughout the Gulf of Mexico. Samples were analyzed by gamma spectrometry with High-Purity Germanium (HPGe) gamma-ray detectors (Canberra Coaxial Planar configuration) for total 210Pb (46.5 keV), 214Pb (295 keV and 351 keV), and 214Bi (609 keV) activities. The mean activity of the 214Pb (295 keV), 214Pb (351 keV), and 214Bi (609 keV) was used as a proxy for 226Ra activity and therefore the supported 210Pb that is produced in situ. The reported excess 210Pb (210Pbxs) is the difference of the total 210Pb and the supported 210Pb.

Chemical Analysis Of Sediment And Fish Species Near The Hercules 265 Blowout, Gulf Of Mexico, 2013, Isabel Romero
Chemical Analysis Of Sediment And Fish Species Near The Hercules 265 Blowout, Gulf Of Mexico, 2013, Isabel Romero
C-IMAGE data
On July 23, 2013 a marine gas rig (Hercules 265) ignited in the northern Gulf of Mexico. The rig burned out of control for several days before being extinguished. We conducted a rapid-response sampling campaign near Hercules 265 after the fire to ascertain if sediments and fishes were polluted above earlier baseline levels. Sediment cores were collected to the SE of the rig at a distance of ~0.2 km, 8 km and 18 km using a multicorer, and demersal fishes were collected from ~0.2 to 8 km SE of the rig using a longline (508 hooks). Recently deposited sediments document …
Dataset For: Simulating Cell Death In The Termination Of Karenia Brevis Blooms: Implications For Predicting Aerosol Toxicity Vectors To Humans, Jason M. Lenes
Dataset For: Simulating Cell Death In The Termination Of Karenia Brevis Blooms: Implications For Predicting Aerosol Toxicity Vectors To Humans, Jason M. Lenes
C-IMAGE data
A non-linear lysis term for simulation of K. brevis HAB termination on the West Florida Shelf is introduced, with the assumption that particle encounters of planktonic microalgae and bacteria can be described as the square of the phytoplankton biomass. This formulation also accounts for nutrient-limitation of K. brevis as a precondition for susceptibility to bacterial and viral attack, and potentially programmed cell death. Two model simulations were run of linear and non-linear lysis cases. Model output was compared against observed weekly maximum K. brevis concentrations, with statistical metrics calculated over three HAB phases during 2001. Introduction of the non-linear lysis …

Hydrocarbons In Deep-Sea Sediments Following The 2010 Deepwater Horizon Oil Spill In The Northeast Gulf Of Mexico, Isabel Romero
C-IMAGE data
High-resolution analyses of sediment cores collected in the aftermath of the Deepwater Horizon (DWH) were conducted to reconstruct the concentration, composition and flux of hydrocarbons to deep-sea (pre-2010, 2010, and 2011) in the DeSoto Canyon, Northeast Gulf of Mexico. Specifically, we analyzed total organic carbon (TOC), aliphatic, polycyclic aromatic hydrocarbon (PAHs), and short-lived radionuclide (234Th, 210Pb) compounds at 2 mm and 5 mm core intervals to elucidate possible hydrocarbon sources and transport pathways to sediments during the time covered in this study. Results showed higher TOC, total aliphatics and PAH fluxes after the DWH blowout (2010-2011) compared to pre-2010 years …
