Oceanography Faculty Articles

Long-distance movements of animals are an important driver of population spatial dynamics and determine the extent of overlap with area-focused human activities, such as fishing. Despite global concerns of declining shark populations, a major limitation in assessments of population trends or spatial management options is the lack of information on their long-term migratory behaviour. For a large marine predator, the tiger shark Galeocerdo cuvier, we show from individuals satellitetracked for multiple years (up to 1101 days) that adult males undertake annually repeated, roundtrip migrations of over 7,500km in the northwest Atlantic. Notably, these migrations occurred between the highly disparate ...

Surface And Subsurface Application Of Chemical Dispersants And Associated Ecosystem Impacts, Adam V. Radpour 2015 University of San Francisco

Surface And Subsurface Application Of Chemical Dispersants And Associated Ecosystem Impacts, Adam V. Radpour

Master's Projects

Chemical dispersants are applied to spilled oil in marine environments when other, less controversial, methods are not adequate for the incident. They are considered to be a response method as opposed to a direct cleanup method, with the intended goals of reducing risk of exposure to sensitive shorelines, reducing environmental injury to surface-dwelling sea birds and marine mammals, and facilitating the biodegradation of spilled oil into the water column.

For this research, both surface and subsurface application of dispersants were evaluated in terms of oil characteristics and volume, and oceanic and atmospheric conditions. More data exists to support the effectiveness ...


Management Recommendations For Restoration Of The Degraded Olympia Oyster, Ostrea Lurida Carpenter 1864 In Tomales Bay, Ca, Carolyn M. Gibson 2015 University of San Francisco

Management Recommendations For Restoration Of The Degraded Olympia Oyster, Ostrea Lurida Carpenter 1864 In Tomales Bay, Ca, Carolyn M. Gibson

Master's Projects

This research addresses the effective restoration of Olympia oyster populations in Tomales Bay, Marin County, California. Chapter 2 provides background information on the Tomales Bay estuary, regional history, and ecology of the Olympia oyster. Following this background discussion, each of the three aforementioned degraders of Olympia oyster populations in Tomales Bay is presented: ocean acidification (Chapter 3), sedimentation (Chapter 4), and invasive species (Chapter 5). Each of these issues creates numerous barriers that require the attention of resource protection managers. Chapter 6 presents overall Research Conclusions and Chapter 7 identifies management recommendations to effectively begin the restoration of the Olympia ...


Dna Analysis Of Surfactant Associated Bacteria In The Sea Surface Microlayer In Application To Satellite Remote Sensing Techniques: Case Studies In The Straits Of Florida And The Gulf Of Mexico, Bryan Hamilton 2015 Nova Southeastern University Oceanographic Center

Dna Analysis Of Surfactant Associated Bacteria In The Sea Surface Microlayer In Application To Satellite Remote Sensing Techniques: Case Studies In The Straits Of Florida And The Gulf Of Mexico, Bryan Hamilton

Theses and Dissertations

Several genera of bacteria residing in the sea surface microlayer and in the near-surface layer of the ocean have been found to be involved in the production and decay of surfactants. Under low wind speed conditions, surfactants can suppress short gravity capillary waves at the sea surface and form natural sea slicks. These features can be observed with both airborne and satellite-based synthetic aperture radar (SAR). Using a new microlayer sampling method, a series of experiments have been conducted in the Straits of Florida and the Gulf of Mexico in 2013 to establish a connection between the presence of surfactant-associated ...


Herbivore Impacts On The Invasive Marine Alga Grateloupia Turuturu, Emily Bishop, Carol Thornber 2015 University of Rhode Island

Herbivore Impacts On The Invasive Marine Alga Grateloupia Turuturu, Emily Bishop, Carol Thornber

Senior Honors Projects

Invasive species have the ability to outcompete natives, and can create a monoculture if not mitigated by herbivores or some other mechanism. Limited information exists on the ecology of the invasive macroalga Grateloupia turuturu and how it is impacted by herbivores. Using laboratory mesocosm experiments, we investigated the ability of two invasive herbivore species common in Rhode Island, the snail Littorina littorea and Asian shore crab Hemigrapsus sanguineus, to control Grateloupia populations. In the first trial, Grateloupia was provided to a single herbivore (either Littorina or Hemigrapsus) or both herbivores together. Grateloupia controls were in the same mesocosms as each ...


Acute Toxicity Of Β-N-Methylamino-L-Alanine (Bmaa) To Fathead Minnow (Pimephales Promelas) And Zebrafish (Danio Rerio), Jiayi Wang 2015 University of Nebraska-Lincoln

Acute Toxicity Of Β-N-Methylamino-L-Alanine (Bmaa) To Fathead Minnow (Pimephales Promelas) And Zebrafish (Danio Rerio), Jiayi Wang

Dissertations & Theses in Natural Resources

β-N-methylamino-L-alanine (BMAA) is a neurotoxic amino acid produced by most species of cyanobacteria. Exposure to BMAA has been hypothesized as a cause of ALS and possibly Parkinson’s and Alzheimer’s diseases for several decades. Both in vitro and in vivo experiments revealed that exposure to elevated concentrations of BMAA can damage motor neurons and cause motor dysfunctions. However, the exact mechanism of BMAA-induced neurotoxicity has not been well understood.

Based on the available literature and in spite of its water-soluble and non-protein nature, BMAA appears to be able to bioaccumulate in organisms. The ubiquity of cyanobacteria and the potential ...


Characterizing The Influence Of Atlantic Water Intrusion On Water Mass Formation And Primary Production In Kongsfjorden, Svalbard, Courtney Michelle Payne 2015 Bowdoin College

Characterizing The Influence Of Atlantic Water Intrusion On Water Mass Formation And Primary Production In Kongsfjorden, Svalbard, Courtney Michelle Payne

Honors Projects

With warming global temperatures and changes to large-scale ocean circulation patterns, warm water intrusion into Arctic fjords is increasingly affecting fragile polar ecosystems. This study investigated how warm Atlantic water intrusion and the tidewater glacial melting it causes impacted water mass formation and primary productivity in Kongsfjorden, Svalbard. Data were collected over a 2-week period during the height of the melt season in August near the Kronebreen/Kongsvegen glacier complex, the most rapidly retreating glacier in Spitsbergen. Since 1998, intruding waters have warmed between 4 and 5.5˚C, which has prevented sea ice formation and changed the characteristics of ...

Linking Old Librarianship To New: Aligning 5-Steps Of The Innovator's Dna In Creating Thematic Discovery Systems For The Everglades, L. Bryan Cooper, Margarita Perez Martinez

Works of the FIU Libraries

This poster presentation from the May 2015 Florida Library Association Conference, along with the Everglades Explorer discovery portal at http://ee.fiu.edu, demonstrates how traditional bibliographic and curatorial principles can be applied to: 1) selection, cross-walking and aggregation of metadata linking end-users to wide-spread digital resources from multiple silos; 2) harvesting of select PDFs, HTML and media for web archiving and access; 3) selection of CMS domains, sub-domains and folders for targeted searching using an API.

Choosing content for this discovery portal is comparable to past scholarly practice of creating and publishing subject bibliographies, except metadata and data are ...


The Acoustics Of Introduction: An Analysis Of Vocalizations From The Captive Introduction Of An Atlantic Bottlenose Dolphin, Tursiops Truncatus, Cheyenne M. Brady 2015 The University of Southern Mississippi

The Acoustics Of Introduction: An Analysis Of Vocalizations From The Captive Introduction Of An Atlantic Bottlenose Dolphin, Tursiops Truncatus, Cheyenne M. Brady

Honors Theses

Vocalizations from dolphins were recorded using a hydrophone on several different occasions: from seven previously-housed dolphins prior to introduction of a new animal and from all eight dolphins together, both on the day of introduction and post-introduction. The vocalizations were categorized by visual inspection of spectrograms using Raven, then totaled and averaged. Total vocalizations appeared to peak during the physical introduction of a new individual to the previously-housed dolphins; however, the rates of vocalization per animal per hour showed that the post-introduction period had the most acoustic communications between individual dolphins. Whistles, chirps (a subcategory of whistles), and unmodulated burst ...

Estimating Growth And Mortality In Elasmobranchs: Are We Doing It Correctly?, Brian J. Moe 2015 Nova Southeastern University Oceanographic Center

Estimating Growth And Mortality In Elasmobranchs: Are We Doing It Correctly?, Brian J. Moe

Theses and Dissertations

The instantaneous mortality rate (M) is an important parameter in elasmobranch management and conservation, but is difficult to estimate directly. Thus, indirect estimates based on relatively easily obtained life history parameters are commonly used. Many indirect methods incorporate one or more parameters from the von Bertalanffy growth model (VBGM), which is often criticized for its inability to describe changes in growth associated with maturity. The Lester growth model (LGM) is a biphasic alternative to the VBGM that incorporates trade-offs between reproduction, growth, and survival, and may therefore more accurately estimate M. I used published data from 29 elasmobranch species to ...

Chemical Warfare In Narragansett Bay: Determining The Allelopathic Effects Of Ulva, Fiona P. MacKechnie, Lindsay A. Green, Carol S. Thornber 2015 University of Rhode Island

Chemical Warfare In Narragansett Bay: Determining The Allelopathic Effects Of Ulva, Fiona P. Mackechnie, Lindsay A. Green, Carol S. Thornber

Senior Honors Projects

Several species of Ulva are commonly found in the waters of Narragansett Bay, especially in eutrophic waters, where they can form fast growing blooms that can have ecological and economic consequences. The formation and release of allelopathic chemicals has been previously documented in some species of Ulva, including Ulva lactuca. Three species of blade-forming Ulva are commonly found in Narragansett Bay and coastal Rhode Island, namely, U. compressa, U. lactuca, and U. rigida. We aimed to determine if these three species of Ulva had allelopathic effects by testing their impacts on the growth of other macroalgae. Cystoclonium purpureum, Chondrus crispus ...


From Shelf To Shelf: Assessing Historical And Contemporary Genetic Differentiation And Connectivity Across The Gulf Of Mexico In Gag, Mycteroperca Microlepis, Nathaniel Kenneth Jue, Thierry Brule, Felicia C. Coleman, Christopher C. Koenig 2015 Florida State University

From Shelf To Shelf: Assessing Historical And Contemporary Genetic Differentiation And Connectivity Across The Gulf Of Mexico In Gag, Mycteroperca Microlepis, Nathaniel Kenneth Jue, Thierry Brule, Felicia C. Coleman, Christopher C. Koenig

FSU Coastal and Marine Laboratory Publications

Describing patterns of connectivity among populations of species with widespread distributions is particularly important in understanding the ecology and evolution of marine species. In this study, we examined patterns of population differentiation, migration, and historical population dynamics using microsatellite and mitochondrial loci to test whether populations of the epinephelid fish, Gag, Mycteroperca microlepis, an important fishery species, are genetically connected across the Gulf of Mexico and if so, whether that connectivity is attributable to either contemporary or historical processes. Populations of Gag on the Campeche Bank and the West Florida Shelf show significant, but low magnitude, differentiation. Time since divergence ...
