A Reflection Of Change: Evolutions In International Water Law Principles Through The Lens Of Euphrates-Tigris Dispute, Maeve Sullivan

Independent Study Project (ISP) Collection

As climate change intensifies, water scarcity will increase. Coupled with a growing global population, water security is a major modern challenge. To bring stability to international watercourses, states must establish effective sharing agreements. On this matter, international water law can help. International water law captures some of the major principles and considerations that states must account for while considering issues related to water security. This paper uses primary interviews and secondary sources to identify some of the major characteristics, features, and developments in international law to develop a conceptual framework for the topic. It then moves into a case study …

A New View Of Chlorophyll Dynamics In The Southern Mid-Atlantic Bight From A Two-Year High-Resolution Spray Glider Survey, Francesco Lane

OES Theses and Dissertations

The southern Mid-Atlantic Bight (MAB) near Cape Hatteras, NC, USA, is likely a hotspot for the episodic export of carbon-rich shelf waters to the open ocean. Over a 2 year period, from March 2017 to May 2019, Spray gliders repeatedly occupied transects, along the slope and across the shelf, generating high-resolution chlorophyll fluorescence (fChl) data in the southern MAB. This study implements an fChl calibration method utilizing remotely sensing ocean color as a standard. We validate the method’s utility by demonstrating a reduction in post-calibration cross-mission fChl variability and demonstrating close correspondence between the calibrated fChl data and an in …

Do Microplastics, Vibrio Bacteria, And Warming Water Temperatures Cause Disease In The Northern Star Coral, Astrangia Poculata?, Heather Leigh Sheffey

OES Theses and Dissertations

As marine plastic pollution increases, it becomes imperative to study the effects of microplastics on marine fauna. Marine plastic debris is a vector for disease to marine invertebrates (Lamb et al., 2018; Rotjan et al., 2019). In this context, studies have shown Astrangia poculata will consume microplastics as they do their normal food (Allen et al, 2017; Rotjan et al., 2019). Further, with temperatures increasing worldwide, there is a concern the virulence of disease-causing bacteria will increase (Vezzulli et al., 2015). In a series of manipulative laboratory experiments, this study quantified changes in respiration rates and visual health of Astrangia …

Rapid Approach For Assessing An Unregulated Fishery Using A Series Of Data-Limited Tools, Carissa L. Gervasi, Mandy Karnauskas, Adyan Rios, Rolando O. Santos, W. Ryan James, Ryan J. Rezek, Jennifer S. Rehage

Marine Science

Objective: Fisheries provide countless benefits to human populations but face many threats ranging from climate change to overfishing. Despite these threats and an increase in fishing pressure globally, most stocks remain unassessed and data limited. An abundance of data-limited assessment methods exists, but each has different data requirements, caveats, and limitations. Furthermore, developing informative model priors can be difficult when little is known about the stock, and uncertain model parameters could create misleading results about stock status. Our research illustrates an approach for rapidly creating robust initial assessments of unregulated and data-limited fisheries without the need for additional data collection. …

Við Pollurinn: The Effects Of Human-Caused Stimuli On Harbor Seals (Phoca Vitulina) In Ísafjörður, Ella Jorgensen

Independent Study Project (ISP) Collection

Harbor seals are important for the health of Iceland’s marine ecosystems. They are normally seen hauled-out onto land to rest. There are many factors that affect the haul-out patterns of harbor seals including location, season, time of day, tide height, weather, and human-caused stimuli. The presence of human-caused stimuli can also have a negative impact on haul-out patterns and behaviors. The Icelandic harbor seal population is threatened as it has been declining since 1980. Climate change and the rise of tourism in Iceland may be a factor contributing to this decline; and there is a gap in knowledge on the …

Robocat: An Autonomous Surface Vehicle (Asv) For Near-Surface Hydrodynamic Measurements In Buoyant Plumes. Development And Case Study, Christopher Tom Papageorgiou

Theses and Dissertations

The study of near surface processes in plumes and other stratified environments requires the collection of hydrodynamic and hydrographic data near the sea surface at high temporal and spatial (in the vertical) resolution. This need led to the design and development of a low-cost autonomous surface vehicle (ASV) equipped with a 5-beam acoustic Doppler current profiler (Nortek 1000 Signature) capable of measuring the vertical structure of both mean flow and turbulence dissipation rate (ε) as close as 30 cm below the sea surface. The ASV is a small catamaran-like platform propelled by four thrusters arranged in an Omni-X configuration, to …

Analyzing The Ramifications Of Climate Change On Mental Health, Salvatore A. Medori

Student Publications

When thinking about the vast array of impacts that the climate crisis has on humanity, there are many things that come to mind, but mental health impacts are likely not one of them. Even though research demonstrates that mental effects from any form of disaster far exceed the physical health implications mental health impacts of the largest disaster facing humanity since the Second World War are rarely considered at all, let alone when solutions are being created. This has led to a hidden crisis emerging underneath an even larger crisis, with serious consequences for most individuals across the globe. The …

Flujos De Servicios Ecosistémicos En Un Área Marina Protegida Del Atlántico Sur: Perspectivas Desde El Análisis De La Teoría De Redes, Mitch Porter

Independent Study Project (ISP) Collection

En cuestiones de gestión de áreas protegidas, los servicios ecosistémicos se tienen cada vez más en cuenta junto con la conservación de la biodiversidad. Sin embargo, las decisiones que se toman sobre la conservación de los servicios ecosistémicos no suelen incluir los posibles efectos en cascada de la pérdida de biodiversidad sobre la provisión de servicios. Los conocimientos de la teoría de redes y los estudios de robustez pueden proporcionar una metodología para evaluar la vulnerabilidad de estos servicios frente la estructura trófica de los ecosistemas que los proveen. A través de una serie de simulaciones de extinción para la …

Climate Change, Malnutrition, And Hiv: The Impact Of Food Insecurity On Hiv Response In Sub-Saharan Africa, Olivia Walshak

Independent Study Project (ISP) Collection

Climate change is a key driver of an unprecedented global food crisis, exacerbated by rising temperatures and the vulnerability of crop yields. Sub-Saharan Africa is particularly susceptible, and case studies demonstrate the fragility of food systems in the region, leading to severe food insecurity and famine in the face of climate shocks.

There are a variety of health implications, particularly the syndemic relationship between malnutrition and HIV. HIV interacts bidirectionally with malnutrition, creating a vicious cycle of poor clinical outcomes. Expanding access to antiretroviral therapy in Sub-Saharan Africa is hindered by rampant food insecurity, including inadequate food intake, reduced dietary …

Carbon Credibility: Strategic Opportunities For Asean Regional Industrial Policy In Voluntary Carbon Markets, Bryan Jed Soh

Independent Study Project (ISP) Collection

Carbon offsets have come under increasing scrutiny due to uncertainties in real carbon abatement, transparency, and fears that it will exacerbate global inequality by allowing the global North to ‘pay to pollute’ through ethically questionable projects in the South. Following Article 2.1.C of the Paris Agreement, this paper argues that the global green transition requires private capital to be fully mobilized through voluntary carbon markets (VCMs). Given that ASEAN states face some of the world’s greatest climate risks while being a fast-growing region, this case study answers the question: how can states play a more proactive role in regulating VCMs …

Understanding The Role Of The Jet Streams And Gulf Stream Eddies On The Northwest Atlantic Marine Heatwaves, Lydia Rose Duncan Sims

Theses and Dissertations

The Northwest (NW) Atlantic is one of the fastest warming regions in the global ocean and in the recent decade has experienced several extreme temperature events. These extreme anomalous temperature events are known as Marine Heatwaves (MHWs), which are forced by a variety of physical processes that affect the heat source and sink of the water column. These MHWs have been increasing globally in duration and frequency due to anthropogenic warming, and have increased ecological damage seen in mass mortality events of economically viable species. Within the NW Atlantic, several key processes encourage the formation of MHWs, such as the …

Organic Carbon Decay Mediated By Mesopelagic Microbial Communities, Noah Jonathan Craft

OES Theses and Dissertations

Substantial remineralization of organic carbon occurs in the mesopelagic zone (i.e., the biological pump), the efficiency of which is responsible for the oceans’ capacity to store carbon originally derived from the atmosphere. To better understand how a substrate’s composition influences its degradation by mesopelagic microbial communities, we added treatments made of live algal cells, dead particulate organic carbon and dissolved organic carbon from ¹⁴C-labeled algal cultures to mesopelagic water collected in-situ. Each incubation took place in the laboratory over a period of months, during which PO¹⁴C, DO¹⁴C, ATP, prokaryote abundances and biochemical fractions were measured. …
