Light Pollution Levels On Beaches: How Window Tinting Effects Disorientation Of Sea Turtles On Hilton Head Island, Kathryn (Kate) Hettiger
Biology: Student Scholarship & Creative Works
Loggerhead sea turtles, an endangered species, are decreasing at alarming rates worldwide. Artificial light from beachfront hotels on Hilton Head Island are causing disorientation in Loggerhead sea turtle hatchlings affecting their ability to successfully find the ocean. To mitigate this, exterior windows facing the ocean will be tinted using either tinting spray, which will be implemented at the Marriott Grande Ocean, or using tinting film, which will be implemented at the Marriott Westin. During the typical nesting and hatching season (May-October), sea turtle hatchling tracks will be recorded using drones to compare the effects of various levels of light pollution …

Marine & Environmental Sciences Faculty Articles
Nearshore coastal waters are highly dynamic in both space and time. They can be difficult to sample using conventional methods due to their shallow depth, tidal variability, and the presence of breaking waves. High resolution satellite sensors can be used to provide synoptic views of Surface Temperature (ST), but the performance of such ST products in the nearshore zone is poorly understood. Close to the shoreline, the ST pixels can be influenced by mixed composition of water and land, as a result of the sensor’s spatial resolution. This can cause thermal adjacency effects due to the highly different diurnal temperature …

Graduate Theses and Dissertations (2019 - present)
Integral parts of local culture along the Eastern Mississippi Sound System (EMSS)- eating raw oysters and fishing- can involve contact with vectors of pathogenic Vibrio spp. bacteria. High mortality rates from vibrio infections demonstrate the need for improved understanding of V. vulnificus and V. parahaemolyticus dynamics in the region. This study assessed: 1) meteorological, 2) hydrographic, and 3) biological correlates of V. parahaemolyticus and V. vulnificus in the EMSS from April-October 2019. Spearman’s correlations, linear mixed models, and non-metric dimensional scaling identified significant relationships between Vibrio spp., abiotic, and biotic parameters of the ecosystem. Vibrio spp. population dynamics were largely …

Phytoplankton Community Response To Upwelling Events: Distribution And Abundance Investigated Using Genomic Methods, Sveinn V. Einarsson
OES Theses and Dissertations
Upwelling events are known to support blooms of phytoplankton, important primary producers at the base of the oceanic food web. Phytoplankton community structure changes in response to upwelling support higher trophic level growth and increased efficiency of carbon export from the euphotic zone. While these events occur globally, this study examined upwelling in coastal regions, where alongshore winds can drive Ekman transport and upwelling of deeper waters. The two upwelling regimes examined were the California Current System and the Alaskan Beaufort Sea. In the California Current System, the relative diatom community composition was examined using 18S sequencing to determine how …

On Inter-Organizational Trust, Control And Risk In Transboundary Fisheries Governance, Gordon M. Hickey, Hunter T. Snyder, Jasper R. Devries, Owen Temby
School of Earth, Environmental, & Marine Sciences Faculty Publications
Inter-organizational collaboration is often considered essential to transboundary fishery governance, due, in part, to the high levels of task interdependence, the remote and often treacherous conditions, and the limited levels of information available to any policy actor on resource status. In the high seas, Regional Fisheries Management Organizations (RFMOs) are responsible for sustainably managing highly migratory and straddling fish stocks through the implementation of ecosystem-based approaches and ensuring adequate inter-jurisdictional cooperation. A central question facing RFMO governance is therefore how to structure and sustain inter-organizational transboundary collaboration under high uncertainty? This paper presents the case of the North Atlantic Salmon …

Variations In Otolith-Zinc Concentrations Of Brown Surgeonfish (Acanthurus Nigrofuscus) Between Marine Protected Areas And Fished Reefs, Matthew Austin Nichols
Theses and Dissertations
As human populations continue to increase, the growing reliance on exploited fish stocks has furthered patterns of declining body size and biomass worldwide. To mitigate these impacts, fisheries managers have implemented a variety of conservation strategies, including marine protected areas (MPA), as these serve as a refuge for fish, resulting in increases in numerous health metrics (fish density, biomass, body-size, and species diversity). By using fish otolith samples previously concluded to have physiological and morphometric differences between MPA and fished reef (FR) fish, this thesis explores the potential of using microchemical analysis of zinc (Zn) to reveal impacts MPAs might …

Methodological Challenges In Studying Trust In Natural Resources Management, Antonia Sohns, Gordon M. Hickey, Jasper R. De Vries, Owen Temby
School of Earth, Environmental, & Marine Sciences Faculty Publications
Trust has been identified as a central characteristic of successful natural resource management (NRM), particularly in the context of implementing participatory approaches to stakeholder engagement. Trust is, however, a multi-dimensional and multi-level concept that is known to evolve recursively through time, challenging efforts to empirically measure its impact on collaboration in different NRM settings. In this communication we identify some of the challenges associated with conceptualizing and operationalizing trust in NRM field research, and pay particular attention to the inter-relationships between the concepts of trust, perceived risk and control due to their multidimensional and interacting roles in inter-organizational collaboration. The …

Shared groundwater resources between Mexico and the United States are facing unprecedented stressors. We reflect on how to improve water security for groundwater systems in the border region. Our reflection begins with the state of groundwater knowledge, and the challenges groundwater resources face from a physical, societal and institutional perspective. We conclude that the extent of ongoing cooperation frameworks, joint and remaining research efforts, from which alternative strategies can emerge, still need to be developed. The way forward offers a variety of cooperation models as the future offers rather complex, shared and multidisciplinary water challenges to the Mexico–US borderlands.

A Meshless Method With Radial Basis Function For Solving Unsaturated Flow In Heterogeneous Porous Media, Cheng-Yu Ku, Chih-Yu Liu, Wei-Po Huang, Jing-En Xiao
Journal of Marine Science and Technology–Taiwan
This paper presents a study for solving unsaturated flow in heterogeneous porous media using the meshless method with the radial basis function (RBF). For modeling the nonlinear hydrological process in unsaturated zone, an exponential model is introduced in the Richards equation such that we may obtain the linearized Richards equation. We adopt the multiquadric function as the RBF in the meshless method for solving the linearized Richards equation. For simulating the unsaturated flow problems in layered heterogeneous soils, the flux and the head must satisfy the continuity condition at the interface. Several examples are carried out for modeling the hydrological …

Journal of Marine Science and Technology–Taiwan
The silky shark, Carcharhinus falciformis, is widely distributed in tropical and temperate waters, and it is a common bycatch species for tuna longline fisheries. This study examined the distribution of and presents relative abundance indices of the silky shark in the Indian Ocean by using logbook and observer data from the Taiwanese large-scale tuna longline fishery between 2005 and 2019. Due to the high zero catch rate, a zero-inflated negative binomial (ZINB) model was used to standardize catch per unit effort. Due to a lack of detailed targeting information, the fishery strategy was identified by using cluster analysis based on …

Journal of Marine Science and Technology–Taiwan
Subsea interventions on wellheads can be directly performed from a platform using a compliant vertical access riser (CVAR), thereby incurring tremendous economic benefits. The dynamic response and the fatigue damage of a CVAR subjected to regular waves are important for assessing its application feasibility. Therefore, a reasonable numerical model is presented for assessing the damage to a CVAR considering the internal flow using the slender rod theory. The finite element method combined with a Newmark-β scheme is employed to discretize the equations and update the time integration. The Palmgren-Miner rule is applied for fatigue life prediction, focusing on the wave-induced …
