Can A Global Fund Help Solve The Global Marine Plastic Debris Problem?, Karen Raubenheimer, Alistair McIlgorm 2018 University of Wollongong

Can A Global Fund Help Solve The Global Marine Plastic Debris Problem?, Karen Raubenheimer, Alistair Mcilgorm

Journal of Ocean and Coastal Economics

The problem of marine plastic debris impacts all of the world’s oceans and requires all nations to respond. However, developing States require funds to improve waste management infrastructure and services in order to reduce marine debris at source. Plastics manufacturers and retailers globally must be incentivised to design products for the environment as well as for the collection and end-of-life treatment facilities available within the intended markets. Given the oceans are a global common, we investigate the option of developing a global fund mechanism to progress the necessary actions to reduce plastic waste entering the world’s oceans. This ...


Shoreline Characterization In The Northern Indian River Lagoon, Melinda Donnelly, Michelle Shaffer, Suzanne Connor, Linda Walters 2018 University of Central Florida

Shoreline Characterization In The Northern Indian River Lagoon, Melinda Donnelly, Michelle Shaffer, Suzanne Connor, Linda Walters

CEELAB Research Data

The purpose of this project was to evaluate current conditions of estuarine shorelines in the northern section of the Indian River Lagoon system, including Mosquito Lagoon, north Indian River, and Banana River. From January 2016 through June 2018, we evaluated structural and functional characteristics of 374 miles of shoreline, from Ponce Inlet in Volusia County to Sebastian Inlet in Brevard County (11,000+ data points). Hard-armoring accounted for approximately 50% of total shoreline, evenly divided between shoreline with bulkheads (25%) and hardened slopes (25%). Forty-five percent of shoreline without hard-armoring had anthropogenic alterations (i.e. mosquito impoundments, railroads and roadways ...

Evaluation Of Spatial Generalization Characteristics Of A Robust Classifier As Applied To Coral Reef Habitats In Remote Islands Of The Pacific Ocean, Justin J. Gapper, Hesham el-Askary, Erik J. Linstead, Thomas Piechota 2018 Chapman University

Evaluation Of Spatial Generalization Characteristics Of A Robust Classifier As Applied To Coral Reef Habitats In Remote Islands Of The Pacific Ocean, Justin J. Gapper, Hesham El-Askary, Erik J. Linstead, Thomas Piechota

Mathematics, Physics, and Computer Science Faculty Articles and Research

This study was an evaluation of the spectral signature generalization properties of coral across four remote Pacific Ocean reefs. The sites under consideration have not been the subject of previous studies for coral classification using remote sensing data. Previous research regarding using remote sensing to identify reefs has been limited to in-situ assessment, with some researchers also performing temporal analysis of a selected area of interest. This study expanded the previous in-situ analyses by evaluating the ability of a basic predictor, Linear Discriminant Analysis (LDA), trained on Depth Invariant Indices calculated from the spectral signature of coral in one location ...

Troubled Waters: Threats And Extinction Risk Of The Sharks, Rays And Chimaeras Of The Arabian Sea And Adjacent Waters, Rima W. Jabado, Peter M. Kyne, Riley A. Pollom, David A. Ebert, Colin A. Simpfendorfer, Gina M. Ralph, Shakha S. Al Dhaheri, K. V. Akhilesh, Khadeeja Ali, Mohamud Hassan Ali

Biological Sciences Faculty Publications

The extinction risk of sharks, rays and chimaeras is higher than that for most other vertebrates due to low intrinsic population growth rates of many species and the fishing intensity they face. The Arabian Sea and adjacent waters border some of the most important chondrichthyan fishing and trading nations globally, yet there has been no previous attempt to assess the conservation status of species occurring here. Using IUCN Red List of Threatened Species Categories and Criteria and their guidelines for application at the regional level, we present the first assessment of extinction risk for 153 species of sharks, rays and ...

Critical habitat was designated in 2003 for federally threatened anadromous Gulf sturgeon to aid in population recovery. This study examined overwintering Gulf sturgeon spatial use and movement through critical habitat monitored by the Ship Island acoustic array from 2011 to 2015. Previous studies observed western population Gulf sturgeon (Pearl and Pascagoula rivers) overwintering near the ends and within the passes of the barrier islands of the Mississippi Sound, USA. Recent telemetry studies detected eastern population fish (Escambia, Blackwater, Yellow, and Choctawhatchee rivers) overwintering as far west as Mobile Bay, Alabama; however, this study is the first to observe eastern population ...


An Evaluation Of Sciaenid Growth In The Gulf Of Mexico, Shane Flinn 2018 Louisiana State University

An Evaluation Of Sciaenid Growth In The Gulf Of Mexico, Shane Flinn

LSU Master's Theses

Growth models estimate life history parameters that are used in the management of fisheries stocks. The most commonly used growth model in fisheries is the von Bertalanffy growth model (VBGM), yet it has been shown to provide a poor fit for length-at-age data of some species and other models exist. I reviewed 196 peer-reviewed age and growth studies and 50 NOAA stock assessments to examine temporal trends in the use of growth models and model selection in fisheries. I found that the use of multi-model frameworks has increased since the year 2000 and information theoretic approaches are replacing goodness-of-fit and ...


Carbon Stocks And Accumulation Rates In Red Sea Seagrass Meadows., Oscar Serrano, Hanan Almahasheer, Carlos M Duarte, Xabier Irigoien 2018 Edith Cowan University

Carbon Stocks And Accumulation Rates In Red Sea Seagrass Meadows., Oscar Serrano, Hanan Almahasheer, Carlos M Duarte, Xabier Irigoien

ECU Publications Post 2013

Seagrasses play an important role in climate change mitigation and adaptation, acting as natural CO2 sinks and buffering the impacts of rising sea level. However, global estimates of organic carbon (Corg) stocks, accumulation rates and seafloor elevation rates in seagrasses are limited to a few regions, thus potentially biasing global estimates. Here we assessed the extent of soil Corg stocks and accumulation rates in seagrass meadows (Thalassia hemprichii, Enhalus acoroides, Halophila stipulacea, Thalassodendrum ciliatum and Halodule uninervis) from Saudi Arabia. We estimated that seagrasses store 3.4 ± 0.3 kg Corg m−2 in 1 m-thick ...


A Climatological Dataset Of Nutrient, Chlorophyll, And Particulate Matter Distributions On The Ross Sea Continental Shelf Derived From Cruise-Based Measurements Spanning 1967 To 2016, Walker O. Smith Jr., Daniel E. Kaufman 2018 Virginia Institute of Marine Science

A Climatological Dataset Of Nutrient, Chlorophyll, And Particulate Matter Distributions On The Ross Sea Continental Shelf Derived From Cruise-Based Measurements Spanning 1967 To 2016, Walker O. Smith Jr., Daniel E. Kaufman

Data

This dataset includes data used in the publication Smith and Kaufman (2018), Progress in Oceanography, which examines the temporal and spatial distributions of nutrients and particulate matter in the Ross Sea continental Shelf using cruise-based observations, and compares the resulting annual productivity estimates with previously reported satellite-based estimates. Specifically, these data represent distributions of nutrients, chlorophyll, particulate organic carbon, particulate organic nitrogen, and biogenic silica that were compiled from 42 cruises (from 1967 - 2016) to the Ross Sea continental shelf to generate a comprehensive climatological dataset for November, December, January, and February. This climatology provides a novel look at broad ...


Quantifying Relationships Between Rock Hardness, Shore Platform Topography, And Intertidal Biota: Oregon Coast, Anna Wood-Gaines, Shannon Hansell, Megan Gravert, Kristin Sweeney 2018 University of Portland

Quantifying Relationships Between Rock Hardness, Shore Platform Topography, And Intertidal Biota: Oregon Coast, Anna Wood-Gaines, Shannon Hansell, Megan Gravert, Kristin Sweeney

Environmental Studies Undergraduate Publications and Presentations

To test the link between rock hardness and meter-scale shore platform morphology and the link between rock hardness and biodiversity, we examined six locations on the Oregon Coast, USA with varying rock types. At each site, we collected rock hardness data along a transect using a Schmidt hammer. To quantify topography, we processed hand-held photographs of each site using structure-from-motion photogrammetry in Agisoft PhotoScan, calculating surface roughness and related statistics in CloudCompare. Our preliminary results confirm that sites with softer rocks tend to have smoother shore platforms and higher levels of biodiversity.


Fish Vertical Distribution And Marine Mammal Co-Occurrence Off Cape Hatteras, Nc, Rachael Aber, John K. Horne 2018 University of Portland

Fish Vertical Distribution And Marine Mammal Co-Occurrence Off Cape Hatteras, Nc, Rachael Aber, John K. Horne

Environmental Studies Undergraduate Publications and Presentations

Mesopelagic (mid-water) fish are important components of toothed whale (Odontocete) diets. Few studies have simultaneous measurements of predator occurrence and potential prey density distributions over long durations. Echoshounder and hydrophone measurements were used to characterize vertical distributions of potential prey and relative abundance of 7 marine mammal groups in the water column off Cape Hatteras, NC. Co-occurrence of the two groups was used as an index of predator-prey interaction. There were fewer than expected (2/7 daily resolution; 1/7 6-hourly resolution) significant correlations between the number of marine mammal occurrences and the potential prey field density. There were no ...


Effects Of Water Temperature, Rearing Temperature And Population On Swimming Performance And Temperature Preference In Atlantic Salmon (Salmo Salar), Nicole Zathey 2018 The University of Western Ontario

Effects Of Water Temperature, Rearing Temperature And Population On Swimming Performance And Temperature Preference In Atlantic Salmon (Salmo Salar), Nicole Zathey

Electronic Thesis and Dissertation Repository

Understanding how animals respond to environmental temperatures is important for the survival and reintroduction of species. My objectives were to determine how swim performance responds across water temperatures, and how rearing temperature or population would affect this performance and temperature preference. Juvenile Atlantic salmon (Salmo salar) from two populations that are currently used for stocking in Lake Ontario (LaHave, Sebago) were reared at two temperatures (11°C, 19°C). I measured critical swim speed and burst swim speed across eight water temperatures (11 – 25°C). Water temperature had no effect on burst speed, while critical swim speed increased with increased ...


Interactive Effects Of Herbivory And Substrate Orientation On Algal Community Dynamics On A Coral Reef, Alain Duran, Ligia Collado-Vides, L. Palma, D. E. Burkepile 2018 Department of Biological Sciences, Florida International University

Interactive Effects Of Herbivory And Substrate Orientation On Algal Community Dynamics On A Coral Reef, Alain Duran, Ligia Collado-Vides, L. Palma, D. E. Burkepile

Department of Biological Sciences

Herbivory is a significant driver of algal community dynamics on coral reefs. However, abiotic factors such as the complexity and orientation of the benthos often mediate the impact of herbivores on benthic communities. We experimentally evaluated the independent and interactive effects of substrate orientation and herbivorous fishes on algal community dynamics on a coral reef in the Florida Keys, USA. We created horizontal and vertical substrates, mimicking the trend in the reduction of vertical surfaces of coral reefs, to assess how algal communities developed either with herbivory (open areas) or without herbivory (herbivore exclosures). We found that substrate orientation was ...

Rich. have been transferred into Myrsine.


Hypoplectrus Liberte, A New And Endangered Microendemic Hamlet From Haiti (Teleostei: Serranidae), Benjamin C. Victor, Kenneth W. Marks 2018 Ocean Science Foundation; Nova Southeastern University

Hypoplectrus Liberte, A New And Endangered Microendemic Hamlet From Haiti (Teleostei: Serranidae), Benjamin C. Victor, Kenneth W. Marks

Marine & Environmental Sciences Faculty Articles

The hamlets of the genus Hypoplectrus comprise a species flock of about 20 species found on coral reefs of the tropical western Atlantic Ocean, distinguished by complex color patterns and sharing mitochondrial DNA haplotypes within the Caribbean Sea (Gulf of Mexico and Florida-centered species are about 3% divergent in the COI marker). The species show a variety of biogeographic patterns, from widespread common species to relatively rare species limited to small parts of the Greater Caribbean region. We describe here a distinctive striped morph of barred hamlet, apparently limited to Fort-Liberté Bay in northeastern Haiti, as the new species Hypoplectrus ...


The Assemblage Structure And Trophic Ecology Of A Deep-Pelagic Fish Family (Platytroctidae) In The Gulf Of Mexico, Michael Novotny 2018 Nova Southeastern University

The Assemblage Structure And Trophic Ecology Of A Deep-Pelagic Fish Family (Platytroctidae) In The Gulf Of Mexico, Michael Novotny

HCNSO Student Theses and Dissertations

Members of the family Platytroctidae (tubeshoulders) are found throughout the meso- and bathypelagic waters of the World Ocean. Due to the lack of specimens collected globally, this taxon has received little attention, despite recent evidence suggesting its predominance in the bathypelagic biome. Prior to this study, only four species had been reported in the Gulf of Mexico’s (GoM) highly diverse deep-pelagic ecosystem. An extensive meso- and bathypelagic trawl series in the GoM allowed a detailed examination of this family, which included analyses of species composition, abundance, vertical distribution, sex ratios, and trophic ecology. A total of 16 species were ...


The Importance Of Marine Predators In The Provisioning Of Ecosystem Services By Coastal Plant Communities, Trisha B. Atwood, Edd Hammill 2018 Utah State University

The Importance Of Marine Predators In The Provisioning Of Ecosystem Services By Coastal Plant Communities, Trisha B. Atwood, Edd Hammill

Ecology Center Publications

Food web theory predicts that current global declines in marine predators could generate unwanted consequences for many marine ecosystems. In coastal plant communities (kelp, seagrass, mangroves, and salt marsh), several studies have documented the far-reaching effects of changing predator populations. Across coastal ecosystems, the loss of marine predators appears to negatively affect coastal plant communities and the ecosystem services they provide. Here, we discuss some of the documented and suspected effects of predators on coastal protection, carbon sequestration, and the stability and resilience of coastal plant communities. In addition, we present a meta-analysis to assess the strength and direction of ...


Ulva Spp. Bloom Dynamics In A Hyper-Eutrophic Estuary: Jamaica Bay, New York, Annesia Lamb 2018 The Graduate Center, City University of New York

Ulva Spp. Bloom Dynamics In A Hyper-Eutrophic Estuary: Jamaica Bay, New York, Annesia Lamb

All Dissertations, Theses, and Capstone Projects

In this dissertation, I present three studies that further our understanding of macroalgae identity, growth, and proliferation. Eutrophication is prevalent in shallow coastal ecosystems world-wide. One of the ecosystem consequences is the development of a bloom forming green marine macroalgae, Ulva spp. Ulva can have negative effects such as Zostera spp. degradation, fish, and shellfish declines. I performed assessments of (1) identity of the bloom-forming Ulva and other macroalgae assemblage, (2) physical, chemical, and biological drivers of Ulva bloom growth and proliferation, and (3) optimal irradiance and temperature requirements for early growth stages in Ulva linza.

The first study is ...


Dermal Mycobacteriosis And Warming Sea Surface Temperatures Are Associated With Elevated Mortality Of Striped Bass In Chesapeake Bay, Maya L. Groner, John M. Hoenig, Roger Pradel, Rémi Choquet, Wolfgang K. Vogelbein, David T. Gauthier, Marjorie A. M. Friedrichs 2018 Old Dominion University

Dermal Mycobacteriosis And Warming Sea Surface Temperatures Are Associated With Elevated Mortality Of Striped Bass In Chesapeake Bay, Maya L. Groner, John M. Hoenig, Roger Pradel, Rémi Choquet, Wolfgang K. Vogelbein, David T. Gauthier, Marjorie A. M. Friedrichs

Biological Sciences Faculty Publications

Temperature is hypothesized to alter disease dynamics, particularly when species are living at or near their thermal limits. When disease occurs in marine systems, this can go undetected, particularly if the disease is chronic and progresses slowly. As a result, population-level impacts of diseases can be grossly underestimated. Complex migratory patterns, stochasticity in recruitment, and data and knowledge gaps can hinder collection and analysis of data on marine diseases. New tools enabling quantification of disease impacts in marine environments include coupled biogeochemical hydrodynamic models (to hindcast key environmental data), and multievent, multistate mark-recapture (MMSMR) (to quantify the effects of environmental ...


Environmental Controls On Depositional Patterns Of Isolated Carbonate Platforms, Jeremy M. Kerr 2018 Nova Southeastern University

Environmental Controls On Depositional Patterns Of Isolated Carbonate Platforms, Jeremy M. Kerr

HCNSO Student Theses and Dissertations

This dissertation explores the influence of the environment on the lateral spatial patterning of facies in modern isolated carbonate platforms through six studies. The first study describes the creation of a database of benthic habitat and bathymetric maps derived from multispectral satellite imagery and the field data used calibrate and validate the mapping algorithms. The second study develops and assesses a new approach for remotely-deriving water depth from multispectral satellite imagery without the need for ground-truth information. The third study identifies a criterion for distinguishing between facies belts and mosaics and deploys the criterion to investigate the co-occurrence of these ...
