Trace Metals And Minor Elements In Southern Gulf Of Mexico Sediments Following The Ixtoc Marine Oil Blow Out Event, 2015, David W. Hastings, Thomas Bartlett Feb 2018

Trace Metals And Minor Elements In Southern Gulf Of Mexico Sediments Following The Ixtoc Marine Oil Blow Out Event, 2015, David W. Hastings, Thomas Bartlett

C-IMAGE data

Our objective is to compare the impact of two marine oil well blowouts on surface sediments in the Gulf of Mexico: the recent 2010 DWH blowout in the Northern Gulf with the Ixtoc blowout in 1979/80 in the Southern Gulf. A suite of trace and minor elements (V, Cr, Mn, Fe, Co, Ni, Cu, Sr, Cd, Mo, Ba, Re, and U) some of which are sensitive to changes in sedimentary redox conditions, was analyzed in bulk surface sediments; that data is presented here. Sediment cores were collected in the SE GoM on a research cruise on the R/V Justo Sierra …

Coral Reef Fishes Exhibit Beneficial Phenotypes Inside Marine Protected Areas, Robert Y. Fidler, Jessica Fidler, Kristen W. Rynerson, Danielle F. Matthews, Ralph G. Turingan Feb 2018

Coral Reef Fishes Exhibit Beneficial Phenotypes Inside Marine Protected Areas, Robert Y. Fidler, Jessica Fidler, Kristen W. Rynerson, Danielle F. Matthews, Ralph G. Turingan

Ocean Engineering and Marine Sciences Faculty Publications

Human fishing effort is size-selective, preferentially removing the largest individuals from harvested stocks. Intensive, size-specific fishing mortality induces directional shifts in phenotypic frequencies towards the predominance of smaller and earlier-maturing individuals, which are among the primary causes of declining fish biomass. Fish that reproduce at smaller size and younger age produce fewer, smaller, and less viable larvae, severely reducing the reproductive capacity of harvested populations. Marine protected areas (MPAs) are extensively utilized in coral reefs for fisheries management, and are thought to mitigate the impacts of size-selective fishing mortality and supplement fished stocks through larval export. However, empirical evidence of …

Proximate Composition And Free Nitrogen-Containing Compounds In Raw Hybrid Abalone (Haliotis Discus Hannai X H. Diversicolor Diversicolor), Commercial Processed Abalone And Abalone Analogue Products, Cheng-Lin Tsai, Chyuan-Yuan Shiau, Hsin-I Hsiao, Wen-Chieh Sung

Journal of Marine Science and Technology–Taiwan

The proximate composition, pH, free amino acids, ammonia and nucleotide-related compounds of raw abalone, commercial processed abalone and abalone analogues were investigated. Taurine was the dominant free amino acid (FAA), accounting for 61.4% of the total FAA in raw hybrid abalone and 29.9% in processed abalone. Abalone analogue products had a high amount of free amino acids, but only 0.3-2.5% taurine. The proximate composition and pH value of abalone changed only slightly after blanching and processing, while the taurine and glycogen content decreased by 50%. FAA profiles were significantly different between commercial processed abalone and analogue products, both of which …

Dna Sequences Of The Mitochondrial Cytochrome C Oxidase I (Coi) Genes From Deep Sea Fishes, Cruises Dp03 And Dp04 From May 2016 - August 2016, Max Weber, Kimberly A. Finnegan, Andrea Bernard, Ron Eytan, Mahmood S. Shivji

DEEPEND Datasets

The deep sea ecosystem is believed to contain the highest biomass of fish in the oceans. However, the taxonomic diversity in this ecosystem is incompletely described and likely to be vastly underestimated. DNA sequence data (barcodes) have become a key tool to discover hidden biodiversity. We generated mitochondrial DNA barcode datasets based on the Cytochrome c oxidase I (COI) gene from deep sea fishes. These data were analyzed using phylogenetic and statistical methods to reveal cryptic species and make taxonomic linkages between adult fishes and their early life stages. These datasets were generated from fishes collected in the northern Gulf …

Cumulative Stress Restricts Niche Filling Potential Of Habitat-Forming Kelps In A Future Climate, Nathan G. King, David C. Wilcockson, Richard Webster, Dan A. Smale, Laura S. Hoelters, Pippa J. Moore

Research outputs 2014 to 2021

Climate change is driving range contractions and local population extinctions across the globe. When this affects ecosystem engineers the vacant niches left behind are likely to alter the wider ecosystem unless a similar species can fulfil them.
Here, we explore the stress physiology of two coexisting kelps undergoing opposing range shifts in the Northeast Atlantic and discuss what differences in stress physiology may mean for future niche filling.
We used chlorophyll florescence (Fv/Fm) and differentiation of the heat shock response (HSR) to determine the capacity of the expanding kelp, Laminaria ochroleuca, to move …

No More Reason For Ignoring Gelatinous Zooplankton In Ecosystem Assessment And Marine Management: Concrete Cost-Effective Methodology During Routine Fishery Trawl Surveys, A. Aubert, E. Antajan, C. Lynam, S. Pitois, A. Pliru, S. Vaz, D. Thibault Feb 2018

No More Reason For Ignoring Gelatinous Zooplankton In Ecosystem Assessment And Marine Management: Concrete Cost-Effective Methodology During Routine Fishery Trawl Surveys, A. Aubert, E. Antajan, C. Lynam, S. Pitois, A. Pliru, S. Vaz, D. Thibault

Student Publications

Gelatinous zooplankton, including cnidarians, ctenophores, and tunicates (appendicularians, pyrosomes, salps and doliolids), are often overlooked by scientific studies, ecosystem assessments and at a management level. Despite the important economic consequences that they can have on human activities and on the marine food-web, arguments often related to the costs of monitoring or their coordination, or simply negligence, have resulted in the absence of relevant monitoring programs. A cost-effective protocol has been applied on trawling from existing fishery surveys conducted by national laboratories in England and France. The testing phase has successfully demonstrated the adequacy of such a tool to sample …

Sharks are a diverse group of mobile predators that forage across varied spatial scales and have the potential to influence food web dynamics. The ecological consequences of recent declines in shark biomass may extend across broader geographic ranges if shark taxa display common behavioural traits. By tracking the original site of photosynthetic fixation of carbon atoms that were ultimately assimilated into muscle tissues of 5,394 sharks from 114 species, we identify globally consistent biogeographic traits in trophic interactions between sharks found in different habitats. We show that populations of shelf-dwelling sharks derive a substantial proportion of their carbon from regional …

Convergent Evolution Of Biochemical Innovations In Polychaetes: Characterizing The Molecular Basis Of Bioluminescence And Venom Production, Aida E. Verdes Gorín Feb 2018

Convergent Evolution Of Biochemical Innovations In Polychaetes: Characterizing The Molecular Basis Of Bioluminescence And Venom Production, Aida E. Verdes Gorín

Dissertations, Theses, and Capstone Projects

The convergent evolution of phenotypic traits is a widespread phenomenon across the tree of life and is explained as the outcome of different taxa facing similar selective forces or environmental conditions. A longstanding question in evolutionary biology is whether the evolution of convergent phenotypes in unrelated lineages is driven by similar or different molecular processes. The research presented here investigates this question by characterizing the molecular basis of two biochemical innovations, bioluminescence and venom production, that have evolved independently in different lineages of polychaetes worms (Annelida). We use an integrative approach, combining next-generation sequencing, phylogenetics and computational tools to evaluate …

Rare Parthenogenic Reproduction In A Common Reef Coral, Porites Astreoides, Alicia A. Vollmer Jan 2018

Rare Parthenogenic Reproduction In A Common Reef Coral, Porites Astreoides, Alicia A. Vollmer

HCNSO Student Theses and Dissertations

Multiple stressors have caused a decline in coral populations. Broadcast spawning corals once dominated the Florida Reef Tract (FRT), but since their decline, smaller brooding corals, soft corals, and macroalgae are replacing them. Brooding corals are more resilient to current threats in part because they are reproductive throughout much of the year and their larvae are competent to settle after release. Despite the ubiquity of brooders on Florida reefs, much of their reproductive strategy remains unknown. This study aimed to examine paternity as a function of colony size and density in Porites astreoides, a common brooding coral in the …

Relative Abundance Of Bacillus Spp., Surfactant-Associated Bacterium Present In A Natural Sea Slick Observed By Satellite Sar Imagery Over The Gulf Of Mexico, Kathryn Howe, Cayla W. Dean, John Alexander Kluge, Alexander Soloviev, Aurelien Tartar, Mahmood S. Shivji, Susanne Lehner, William Perrie

Marine & Environmental Sciences Faculty Articles

The damping of short gravity-capillary waves (Bragg waves) due to surfactant accumulation under low wind speed conditions results in the formation of natural sea slicks. These slicks are detectable visually and in synthetic aperture radar satellite imagery. Surfactants are produced by natural life processes of many marine organisms, including bacteria, phytoplankton, seaweed, and zooplankton. In this work, samples were collected in the Gulf of Mexico during a research cruise on the R/V F.G. Walton Smith to evaluate the relative abundance of Bacillus spp., surfactant-associated bacteria, in the sea surface microlayer compared to the subsurface water at 0.2 m depth. A …

C-IMAGE Publications

We use a spatially explicit biogeochemical end-to-end ecosystem model, Atlantis, to simulate impacts from the Deepwater Horizon oil spill and subsequent recovery of fish guilds. Dose-response relationships with expected oil concentrations were utilized to estimate the impact on fish growth and mortality rates. We also examine the effects of fisheries closures and impacts on recruitment. We validate predictions of the model by comparing population trends and age structure before and after the oil spill with fisheries independent data. The model suggests that recruitment effects and fishery closures had little influence on biomass dynamics. However, at the assumed level of oil …

Dietary Overlap Between Jellyfish And Forage Fish In The Northern Gulf Of Mexico, Isabella D'Ambra, William M. Graham, Ruth H. Carmichael, Frank J. Hernandez Jr. Jan 2018

Dietary Overlap Between Jellyfish And Forage Fish In The Northern Gulf Of Mexico, Isabella D'Ambra, William M. Graham, Ruth H. Carmichael, Frank J. Hernandez Jr.

Faculty Publications

Despite the speculations that jellyfish (hydromedusae, siphonophores, scyphomedusae and ctenophores) may compete with forage fish for prey, there are few direct comparisons of their diets. To determine the dietary overlap between Aurelia sp. (Cnidaria, Scyphozoa) and Brevoortia patronus (Goode, 1878) (Pisces, Clupeidae) in the northern Gulf of Mexico, we collected monthly samples in Louisiana, Mississippi and Alabama coastal waters (USA) during summer and early fall 2009−2010. We determined carbon and nitrogen stable isotope ratios in predators and their potential prey, including small plankton (<200 µm) and mesozooplankton (200− 2000 µm), and identified prey in the stomachs of adult Aurelia sp. and B. patronus. Trophic niche overlap was defined using the stable isotope Bayesian …

Modeling Chlorophyll Concentrations On The Ohio River Using Remotely Sensed Data, Thaddaeus Stephen Tuggle Jan 2018

Modeling Chlorophyll Concentrations On The Ohio River Using Remotely Sensed Data, Thaddaeus Stephen Tuggle

Theses, Dissertations and Capstones

Traditional direct water quality methodologies limit the ability to spatially and temporally predict algal blooms in lotic systems due to the size and characteristics of large river systems. Algal blooms potentially can be predicted by knowing the spatial and temporal patterns of change in cyanobacteria concentrations at large scales. Remote sensing studies investigating freshwater algal blooms, some known to secrete harmful toxins, are primarily conducted on lentic systems while large lotic systems are greatly ignored. In this study I developed a chlorophyll concentration estimation model for the Ohio River using a satellite remote sensing approach. Ground-truth water quality measures, including …

Jackson Estuarine Laboratory

The present impacts from coastal storms and high tides grow significantly over time due to SLR even over the relatively short period to 2060. Hydrodynamic model simulations of storm surge with and without sea level rise scenarios show that although flooding and inundation increases with increasing subtidal forcing and higher sea level, dissipation of the tide and storm surge in the estuary channel somewhat limits the maximum inundation that might otherwise be expected in the back marsh areas. The estuary is dominated by high marsh, which lies high in the intertidal zone and by 2060 it will convert to mostly …

During their migrations, marine predators experience varying levels of protection and face many threats as they travel through multiple countries’ jurisdictions and across ocean basins. Some populations are declining rapidly. Contributing to such declines is a failure of some international agreements to ensure effective cooperation by the stakeholders responsible for managing species throughout their ranges, including in the high seas, a global commons. Here we use biologging data from marine predators to provide quantitative measures with great potential to inform local, national and international management efforts in the Pacific Ocean. We synthesized a large tracking data set to show how …

Estimating Exploitation Rates In The Alabama Red Snapper Fishery Using A High-Reward Tag–Recapture Approach, Dana K. Sackett, Mattgew Catalano, J. Marcus Drymon, Sean P. Powers, Mark Albins

University Faculty and Staff Publications

Accurate estimates of exploitation are essential to managing an exploited fishery. However, these estimates are often dependent on the area and vulnerable sizes of fish considered in a study. High-reward tagging studies offer a simple and direct approach to estimating exploitation rates at these various scales and in examining how model parameters impact exploitation rate estimates. These methods can ultimately provide a better understanding of the spatial dynamics of exploitation at smaller local and regional scales within a fishery—a measure often needed for more site-attached species, such as the Red Snapper Lutjanus campechanus. We used this approach to tag 724 …
