Species Specific Metabolic Capacity Of Naphthalene And Phenanthrene In Three Species Of Marine Teleosts Exposed To Deepwater Horizon Crude Oil, Erin Pulster

C-IMAGE data

Select monohydroxylated polycyclic aromatic hydrocarbons (PAHs) metabolites were measured in three marine teleosts, red drum (Sciaenops ocellatus), Florida pompano (Trachinotus carolinus) and southern flounder (Paralichthys lethostigma) to evaluate species specific metabolic differences. Fish were exposed to DWH crude oil by intraperitoneal (i.p.) injections at time 0 and 48 hours with bile sampling events at 24 and 72 hours post injection. Biliary levels of monohydroxylated naphthalene and phenanthrene metabolites were confirmed and quantified using gas chromatography triple quadrapole mass spectrometry.

Optical Backscattering Measured By Airborne Lidar And Underwater Glider, James H. Churnside, Richard D. Marchbanks, Chad Lembke, Jordon Beckler

Marine Science Faculty Publications

The optical backscattering from particles in the ocean is an important quantity that has been measured by remote sensing techniques and in situ instruments. In this paper, we compare estimates of this quantity from airborne lidar with those from an in situ instrument on an underwater glider. Both of these technologies allow much denser sampling of backscatter profiles than traditional ship surveys. We found a moderate correlation (R = 0.28, p < 10⁻⁵), with differences that are partially explained by spatial and temporal sampling mismatches, variability in particle composition, and lidar retrieval errors. The data suggest that there are two …

Large-Scale Deposition Of Weathered Oil In The Gulf Of Mexico Following A Deep-Water Oil Spill, Isabel Romero, Gerardo Toro-Farmer, Arne R. Diercks, Patrick Schwing, Frank E. Muller-Karger, Steven Murawski, David Hollander

Marine Science Faculty Publications

The blowout of the Deepwater Horizon (DWH) drilling rig in 2010 released an unprecedented amount of oil at depth (1,500 m) into the Gulf of Mexico (GoM). Sedimentary geochemical data from an extensive area (∼194,000 km2) was used to characterize the amount, chemical signature, distribution, and extent of the DWH oil deposited on the seafloor in 2010–2011 from coastal to deep-sea areas in the GoM. The analysis of numerous hydrocarbon compounds (N = 158) and sediment cores (N = 2,613) suggests that, 1.9 ± 0.9 × 104 metric tons of hydrocarbons (>C9 saturated and aromatic fractions) were deposited in …

Generation Of Germ-Free /Ciona Intestinalis For Studies Of Gut-Microbe Interactions, Brittany A Leigh, Assunta Liberti, Larry J Dishaw

Marine Science Faculty Publications

Microbes associate with animal hosts, often providing shelter in a nutrient-rich environment. The gut, however, can be a harsh environment with members of the microbiome settling in distinct niches resulting in more stable, adherent biofilms. These diverse communities can provide orders of magnitude more gene products than the host genome; selection and maintenance of a functionally relevant and useful microbiome is now recognized to be an essential component of homeostasis. Germ-free (GF) model systems allow dissection of host-microbe interactions in a simple and direct way where each member of the symbiosis can be studied in isolation. In addition, because immune …

Towards Quantitative Viromics For Both Double-Stranded And Single-Stranded Dna Viruses., Simon Roux, Natalie E Solonenko, Vinh T Dang, Bonnie T Poulos, Sarah M Schwenck, Dawn B Goldsmith, Maureen L Coleman, Mya Breitbart, Matthew B Sullivan

Marine Science Faculty Publications

BACKGROUND: Viruses strongly influence microbial population dynamics and ecosystem functions. However, our ability to quantitatively evaluate those viral impacts is limited to the few cultivated viruses and double-stranded DNA (dsDNA) viral genomes captured in quantitative viral metagenomes (viromes). This leaves the ecology of non-dsDNA viruses nearly unknown, including single-stranded DNA (ssDNA) viruses that have been frequently observed in viromes, but not quantified due to amplification biases in sequencing library preparations (Multiple Displacement Amplification, Linker Amplification or Tagmentation).

METHODS: Here we designed mock viral communities including both ssDNA and dsDNA viruses to evaluate the capability of a sequencing library preparation …

Temporal Variability Of Diapycnal Mixing In The Northern South China Sea, Hui Sun, Qingxuan Yang, Wei Zhao, Xinfeng Liang, Jiwei Tian

Marine Science Faculty Publications

Temporal variability of diapycnal mixing over 7 months in the northern South China Sea was examined based on McLane Moored Profiler observations from 850 to 2200 m by employing a finescale parameterization. Intensified diffusivity exceeding the order of 10⁻³ m²/s in magnitude was found over the first half of October 2014, and from 2 December 2014 to 21 January 2015 (a typical wintertime). Strong internal tides and winds in winter were the likely candidates for the high‐level diapycnal mixing in winter. As for the enhanced mixing during October 2014, we suspect the generation of near‐bottom near‐inertial waves …

Variability Of Particle Size Distributions In The Bohai Sea And The Yellow Sea, Zhongfeng Qui, Deyong Sun, Chuanmin Hu, Sengquiang Wang, Lufei Zheng, Yu Huang, Tian Peng

Marine Science Faculty Publications

Particle size distribution (PSD) is an important parameter that is relevant to many aspects of marine ecosystems, such as phytoplankton functional types, optical absorption and scattering from particulates, sediment fluxes, and carbon export. However, only a handful of studies have documented the PSD variability in different regions. Here, we investigate the PSD properties and variability in two shallow and semi-enclosed seas (the Bohai Sea (BS) and Yellow Sea (YS)), using in situ laser diffraction measurements (LISST-100X Type C) and other measurements at 79 stations in November 2013. The results show large variability in particle concentrations (in both volume and number …

The Skp1 Homologs Skr-1/2 Are Required For The Caenorhabditis Elegans Skn-1 Antioxidant/Detoxification Response Independently Of P38 Mapk., Cheng-Wei Wu, Andrew Deonarine, Aaron Przybysz, Kevin Strange, Keith P. Chloe

Molecular Biosciences Faculty Publications

SKN-1/Nrf are the primary antioxidant/detoxification response transcription factors in animals and they promote health and longevity in many contexts. SKN-1/Nrf are activated by a remarkably broad-range of natural and synthetic compounds and physiological conditions. Defining the signaling mechanisms that regulate SKN-1/Nrf activation provides insights into how cells coordinate responses to stress. Nrf2 in mammals is regulated in part by the redox sensor repressor protein named Keap1. In C. elegans, the p38 MAPK cascade in the intestine activates SKN-1 during oxidative stress by promoting its nuclear accumulation. Interestingly, we find variation in the kinetics of p38 MAPK activation and tissues with …

Quantifying Trace Element And Isotope Fluxes At The Ocean-Sediment Boundary: A Review., William B. Homoky, Thomas Weber, William M. Berelson, Tim M. Conway, Gideon M. Henderson, Marco Van Hulten, Catherine Jeandel, Silke Severmann, Alessandro Tagliabue

Marine Science Faculty Publications

Quantifying fluxes of trace elements and their isotopes (TEIs) at the ocean's sediment-water boundary is a pre-eminent challenge to understand their role in the present, past and future ocean. There are multiple processes that drive the uptake and release of TEIs, and properties that determine their rates are unevenly distributed (e.g. sediment composition, redox conditions and (bio)physical dynamics). These factors complicate our efforts to find, measure and extrapolate TEI fluxes across ocean basins. GEOTRACES observations are unveiling the oceanic distributions of many TEIs for the first time. These data evidence the influence of the sediment-water boundary on many TEI cycles, …

Hearing In The Juvenile Green Sea Turtle (Chelonia Mydas): A Comparison Of Underwater And Aerial Hearing Using Auditory Evoked Potentials, Wendy E D Piniak, David A Mann, Craig A Harms, T Todd Jones, Scott A Eckert

Marine Science Faculty Publications

Sea turtles spend much of their life in aquatic environments, but critical portions of their life cycle, such as nesting and hatching, occur in terrestrial environments, suggesting that it may be important for them to detect sounds in both air and water. In this study we compared underwater and aerial hearing sensitivities in five juvenile green sea turtles (Chelonia mydas) by measuring auditory evoked potential responses to tone pip stimuli. Green sea turtles detected acoustic stimuli in both media, responding to underwater stimuli between 50 and 1600 Hz and aerial stimuli between 50 and 800 Hz, with maximum sensitivity between …

Processes Of Multibathyal Aragonite Undersaturation In The Arctic Ocean, Jonathan G. Wynn, Lisa Robbins, L. G. Anderson

School of Geosciences Faculty and Staff Publications

During 3 years of study (2010–2012), the western Arctic Ocean was found to have unique aragonite saturation profiles with up to three distinct aragonite undersaturation zones. This complexity is produced as inflow of Atlantic‐derived and Pacific‐derived water masses mix with Arctic‐derived waters, which are further modified by physiochemical and biological processes. The shallowest aragonite undersaturation zone, from the surface to ∼30 m depth is characterized by relatively low alkalinity and other dissolved ions. Besides local influence of biological processes on aragonite undersaturation of shallow coastal waters, the nature of this zone is consistent with dilution by sea‐ice melt and invasion …

Dissolved Iron And Iron Isotopes In The Southeastern Pacific Ocean, Jessica N. Fitzsimmons, Tim M. Conway, Jong-Mi Lee, Richard Kayser, Kristen M. Thyng, Seth G. John, Edward A. Boyle

Marine Science Faculty Publications

The Southeast Pacific Ocean is a severely understudied yet dynamic region for trace metals such as iron, since it experiences steep redox and productivity gradients in upper waters and strong hydrothermal iron inputs to deep waters. In this study, we report the dissolved iron (dFe) distribution from seven stations and Fe isotope ratios (δ⁵⁶Fe) from three of these stations across a near‐zonal transect from 20 to 27°S. We found elevated dFe concentrations associated with the oxygen‐deficient zone (ODZ), with light δ⁵⁶Fe implicating porewater fluxes of reduced Fe. However, temporal dFe variability and rapid δ⁵⁶Fe …

Experimental Assessment Of Lionfish Removals To Mitigate Reef Fish Community Shifts On Northern Gulf Of Mexico Artificial Reefs, Kristin A. Dahl, William F. Patterson Iii, Richard A. Synder

C-IMAGE Publications

Substantial declines in reef fishes were observed at northern Gulf of Mexico artificial reef sites between 2009−2010 and 2011−2012, a period that bracketed the appearance of invasive lionfish in this ecosystem. Small demersal reef fishes, the predominant prey of lionfish in other systems, displayed the greatest declines. However, a confounding factor during this time was the Deepwater Horizon Oil Spill (DWH) in summer 2010. In some areas, targeted lionfish removals have been demonstrated to mitigate negative effects on native fishes. Therefore, we conducted a 2 yr experiment to examine the effectiveness and ecological benefits of targeted lionfish removals at artificial …
