Calibration Of Perfluorinated Alkyl Acid Uptake Rates By A Tube Passive Sampler In Water, Matthew Dunn, Jitka Becanova, Jarod Snook, Bridger Ruyle, Rainer Lohmann

Graduate School of Oceanography Faculty Publications

Per- and polyfluoroalkyl substances (PFAS) are a group of 4000+ man-made compounds of great concern due to their environmental ubiquity and adverse effects. Despite general interest, few reliable detection tools for integrative passive sampling of PFAS in water are available. A microporous polyethylene tube with a hydrophilic–lipophilic balance sorbent could serve as a flow-resistant passive sampler for PFAS. The tube’s sampling rate, Rs, was predicted based on either partitioning and diffusion or solely diffusion. At 15 °C, the laboratory-measured Rs for perfluorohexanoic acid of 100 ± 81 mL day–1 was better predicted by a partitioning …

Drinking water supplies across the United States have been contaminated by firefighting and fire-training activities that use aqueous film-forming foams (AFFF) containing per- and polyfluoroalkyl substances (PFAS). Much of the AFFF is manufactured using electrochemical fluorination by 3M. Precursors with six perfluorinated carbons (C6) and non-fluorinated amine substituents make up approximately one-third of the PFAS in 3M AFFF. C6 precursors can be transformed through nitrification (microbial oxidation) of amine moieties into perfluorohexane sulfonate (PFHxS), a compound of regulatory concern. Here, we report biotransformation of the most abundant C6 sulfonamido precursors in 3M AFFF with available commercial standards (FHxSA, PFHxSAm, and …

The emergence of 100-Kyr glacial cycles (The Mid-Pleistocene Transition [MPT]) is attributed in part to slower global overturning circulation and iron stimulation of biological carbon drawdown in the Southern Ocean. We present foraminifera-bound nitrogen isotope values and polar planktic foraminifera abundances from the Agulhas Plateau that show that increases in biogenic sediment accumulation coincide with northward migrations of the Subtropical Frontal Zone (STFZ) and elevated foraminifera-bound nitrogen isotope values during MPT glacial episodes. The nitrogen isotope values of two planktic foraminifera species, Globigerina bulloides and Globorotalia inflata show remarkable coherence amongst the sea surface temperature gradient between the STFZ and …

Barber, Heidi M. Pickard, David A. Alvarez, Jitka Becanova, Steffanie H. Keefe, Denise R. Leblanc, Rainer Lohmann, Jeffrey A. Steevens, Alan M. Vajda

Graduate School of Oceanography Faculty Publications

Aqueous film-forming foams historically were used during fire training activities on Joint Base Cape Cod, Massachusetts, and created an extensive per- and polyfluoroalkyl substances (PFAS) groundwater contamination plume. The potential for PFAS bioconcentration from exposure to the contaminated groundwater, which discharges to surface water bodies, was assessed with mobile-laboratory experiments using groundwater from the contamination plume and a nearby reference location. The on-site continuous-flow 21-day exposures used male and female fathead minnows, freshwater mussels, polar organic chemical integrative samplers (POCIS), and polyethylene tube samplers (PETS) to evaluate biotic and abiotic uptake. The composition of the PFAS-contaminated groundwater was complex and …

Little is known about dispersal in deep-sea ecosystems, especially for sponges, which are abundant ecosystem engineers. Understanding patterns of gene flow in deep-sea sponges is essential, especially in areas where rising pressure from anthropogenic activities makes difficult to combine management and conservation. Here, we combined population genomics and oceanographic modelling to understand how Northeast Atlantic populations (Cantabrian Sea to Norway) of the deep-sea sponge Phakellia ventilabrum are connected. The analysis comprised ddRADseq derived SNP datasets of 166 individuals collected from 57 sampling stations from 17 different areas, including two Marine Protected Areas, one Special Area of Conservation and other areas …

A Closer Look At The Role Of Precipitation And Air-Sea Gas Exchange Of Circumpolar Waters In The Eastern Amundsen Sea, Antarctica, Virginia Cousens Jan 2023

A Closer Look At The Role Of Precipitation And Air-Sea Gas Exchange Of Circumpolar Waters In The Eastern Amundsen Sea, Antarctica, Virginia Cousens

Open Access Master's Theses

Pine Island Glacier in the remote Amundsen Sea has exhibited some of the most pronounced thinning and retreat in Western Antarctica in recent decades, resulting in significant influx of freshwater to the region. These dynamic changes are caused by climate sensitive processes from warming ocean currents to changing air temperature. Glacial melt in this region has been thought to dominate the freshwater budget, but meltwater tracers suggest precipitation may also be significant in terms of freshwater flux. Here, we take a closer look at the magnitude of precipitation derived from oxygen-18 and noble gases as freshwater tracers and seek to …

The Response Of Benthic Communities In Narragansett Bay To Changing Nitrogen Input And Temperature, Shaina Harkins Jan 2023

The Response Of Benthic Communities In Narragansett Bay To Changing Nitrogen Input And Temperature, Shaina Harkins

Open Access Master's Theses

Marine ecosystem changes are often driven by different forces simultaneously, making it challenging to evaluate the individual contributions of each force. In Narragansett Bay, nitrogen input from wastewater treatment facilities (WWTF) was successfully decreased by 50% from 2005 to 2013. In the last 50 years, surface water temperature in the Bay has also increased by 1.6°C. The response of the benthic community to either of these changes has yet to be determined. We replicated the historical methodology of diver collected cores for infaunal macrofauna, organisms living in sediment, and included beam trawl sampling to catch larger, more mobile epifauna, organisms …

Developing A Low-Cost Stereo Imaging System For Quantitative Visual Modeling Of Marine Environments, Alexandra T. Runyan Jan 2023

Developing A Low-Cost Stereo Imaging System For Quantitative Visual Modeling Of Marine Environments, Alexandra T. Runyan

Open Access Master's Theses

Structure-from-Motion (SfM) photogrammetry has become an increasingly useful tool in recent years for underwater surveys of seafloor environments. The resulting digital 3D reconstructions from SfM provide rich information for quantifying changes in benthic communities and allow for more effective long-term monitoring and conservation efforts. In coastal waters, the current method involves divers placing physical ground control points (GCPs) and scale-bars on the substrate, swimming in a boustrophedon pattern over the substrate, and taking several overlapping images with high-cost digital cameras. The necessity of GCPs and divers when using a single camera greatly limits the depths in which spatially rectified SfM …

Power And Sample Size Calculations For Evaluating Spillover Effects In Networks With Non-Randomized Interventions, Ke Zhang Jan 2023

Power And Sample Size Calculations For Evaluating Spillover Effects In Networks With Non-Randomized Interventions, Ke Zhang

Open Access Master's Theses

Determining the appropriate sample size that is needed to achieve a desired level of statistical power is an integral aspect of study design, as it ensures that studies are adequately powered and that their results are reliable and meaningful. Adequate statistical power can also address some practical and ethical considerations. Various methodologies for power and sample size calculations have been developed for distinct types of studies. However, the implications for power when estimating spillover effects in sociometric network-based studies with non-randomized interventions (SNS-NRIs) remain inadequately explored. In this study, we first conducted a series of simulations to evaluate how the …

Analysis Of Turkey Reovirus Using Machine Learning, Maryam Kafikang Jan 2023

Analysis Of Turkey Reovirus Using Machine Learning, Maryam Kafikang

Open Access Master's Theses

Avian reoviruses continue to cause disease in turkeys with varied pathogenicity and tissue tropism. Turkey enteric reovirus (TERV) has been identified as a causative agent of enteritis or inapparent infections in turkeys. The new emerging variants of turkey reovirus tentatively named as turkey arthritis reovirus (TARV) and turkey hepatitis reovirus (THRV) are linked to tenosynovitis/arthritis and hepatitis, respectively. Turkey arthritis and hepatitis reoviruses are causing significant economic losses to the turkey industry. These infections can lead to poor weight gain, uneven growth, poor feed conversion, increased morbidity and mortality, and reduced marketability of commercial turkeys. To combat these issues, it …

On The Utility Of Multi-Species Foraminifera-Bound Δ15n Records For Subtropical Front Migration Analysis, Shalan Mcdonagh Jan 2023

On The Utility Of Multi-Species Foraminifera-Bound Δ15n Records For Subtropical Front Migration Analysis, Shalan Mcdonagh

Open Access Master's Theses

>The Subtropical front (STF) is an area of intense mixing between the cold Southern Ocean and the warm subtropical South Indian Ocean. On interglacial-glacial timescales the STF migrates, altering surface chemical and biological conditions as it moves. A recent study interpreted this migration through changes in the isotopic composition of nitrogen in the surface ocean during the Last Glacial Period by measuring the isotopic composition of nitrogen of foraminifera-bound nitrogen in a single species of foraminifera. Relying on a single species interpretation in this dynamic mixing zone may bias toward species-related ecological preferences. Here we explore the possibility that measuring …

Blue Carbon And Microplastic Sequestration In Coastal Habitats Of The Philippines, Emily Hall Jan 2023

Blue Carbon And Microplastic Sequestration In Coastal Habitats Of The Philippines, Emily Hall

Open Access Master's Theses

Climate change and human development pose significant threats to coastal ecosystems, and an understanding of the history of these ecosystems is necessary to assess potential climate mitigation and coastal resiliency strategies. The high-resolution histories in coastal vegetated habitats, enabled by high sedimentation rates, record long-term sequestration of below-ground carbon as well as the history of pollutants such as microplastics. Rates of sequestration, in addition to bulk storage estimates, are needed to inform future management decisions. This study documents organic carbon and microplastic concentrations and accumulation rates from five distinct sites in the southern Philippines. The carbon and plastic records are …

A Sample Efficient Off-Policy Actor-Critic Approach For Discrete Action Environments, Nicholas Clavette Jan 2023

A Sample Efficient Off-Policy Actor-Critic Approach For Discrete Action Environments, Nicholas Clavette

Open Access Master's Theses

In the current reinforcement learning (RL) taxonomy, there exist few algorithms for discrete action environments that are capable of learning stochastic policies in an off-policy manner. Learning stochastic policies brings benefits such as stable training and smoother exploration strategies. Training an algorithm in an off-policy manner allows for greater sample efficiency, as experiences collected while interacting with a learning environment can be used more than once. Stable performance and good sample efficiency are highly important when collecting experiences from a learning environment is expensive. This thesis proposes a new algorithm for discrete action RL called Discrete General Policy Optimization (Discrete …

Assessing Well-Being Impacts Of Sargassum Events In Puerto Rico, Patricia Valentin

Open Access Master's Theses

Since 2011, Sargassum events have become larger and more recurrent in Puerto Rico and appear to have come to stay. While some studies have described economic and ecological impacts on the archipelago, studies of Sargassum impact on human well-being are lacking. However, in the context of Puerto Rico, only a few studies have been conducted in terms of general impacts of sargassum events and its management. Puerto Rico, like most territories of the region, lacks an efficient strategy for sargassum management. Currently, only one set of protocols or guidelines has been produced since sargassum accumulations have become an issue for …

Green Nation: State Forestry And Its Failures In The Atlantic Pyrenees, 1827-1848, Timothy R. Jarvis Jan 2023

Green Nation: State Forestry And Its Failures In The Atlantic Pyrenees, 1827-1848, Timothy R. Jarvis

Open Access Master's Theses

This thesis argues that state forestry programs in nineteenth-century France failed to produce adequate conservation systems, resulting in the devastation of the natural world. After the revolutionary era, a highly centralized and technocratic state attempted to solve old environmental problems with modernized solutions. This tension between old and new ways of thinking reached a watershed moment during the middle of the nineteenth century, when Romantic and Enlightenment worldviews clashed within the environmental theater of state forestry. This confrontation radically transformed how the French perceived and interacted with nature. Concepts such as radical empiricism, biological evolution, and natural theology became cultural …

The Social And Ecological Dimensions Of Coral Reef Biomonitoring, Elaine Wang Shen Jan 2023

The Social And Ecological Dimensions Of Coral Reef Biomonitoring, Elaine Wang Shen

Open Access Dissertations

Coral reefs contain a disproportionately high amount of marine biodiversity and support millions of people worldwide by providing food security and livelihoods. This coupled relationship between reefs and people is increasingly threatened globally by climate change and globalization, as well as locally by overfishing, habitat destruction, and nutrient pollution. Biomonitoring the varied ecological outcomes of these threats and estimating how conservation and management interventions mitigate them are crucial scientific endeavors for understanding the socio-ecological complexity of coral reef dynamics. Common ecological indicators of reef health, however, are theoretically and taxonomically limited when used alone, thus a combination of modeling and …
