Understanding The Public Perception Of Available Scientific Resources In Coastal Southern Maine, James Gallagher
Understanding The Public Perception Of Available Scientific Resources In Coastal Southern Maine, James Gallagher
Senior Honors Projects
I have focused my education as an undergrad towards the effective communication of scientific fact to non-scientific groups. This area of study has recently been dubbed Science Communication and it encompasses the effective articulation, communication, and education of scientific topics to people who haven’t dedicated their lives to scientific study. A major component of effective Scientific Communication is understanding your audience and what kind of communication strategies are best for a chosen demographic.
I grew up in Ocean Park Maine, a small town on the coast of Southern Maine which drove my interest in Marine Science. With my experience in …
A Step Toward Reconstructing Climate Variability Druing The Last Ice Age Cycle In The Northeast Pacific Region, Blaine Lynch-Gadaleta
A Step Toward Reconstructing Climate Variability Druing The Last Ice Age Cycle In The Northeast Pacific Region, Blaine Lynch-Gadaleta
Senior Honors Projects
This study is designed as a step toward reconstructing the climate variability in the Northeast Pacific during the last ice age cycle, including the glacial and deglacial transitions. Reconstruction may also contribute to the regional picture of climate change and potentially provide new insights into the pattern of variability in the Northeast Pacific. Deep-sea sediment core AT26-19 09PC was collected west of the Juan de Fuca Ridge in the Northeast Pacific Ocean. Samples were analyzed in 1 cm intervals, representing approximately 300-year resolution. The abundance of mineral grains, planktonic foraminifera, and the polar foraminifera N.pachyderma was quantified using split aliquots …

Flow Model Of Offshore Input Of Nitrogen Into The Narragansett Bay, Christopher M. Sireci
Flow Model Of Offshore Input Of Nitrogen Into The Narragansett Bay, Christopher M. Sireci
Senior Honors Projects
Nitrogen is an important nutrient in ecosystems, as it is used in many biological processes, including the creation of DNA and RNA. However, excess nitrogen in an ecosystem can have adverse effects, such as triggering algal blooms, which limit sunlight penetration to bottom growth, and create anoxic zones. Large scale strategies to remove excess nitrogen from wastewater treatment plants have been utilized, but they are expensive and can potentially remove too much, while increasing greenhouse gas emissions. Thus, it is essential that we understand the accurate full nitrogen budget for an estuary.
Narragansett Bay, an important coastal marine ecosystem that …

Do Halogenated Natural Products Bioaccumulate In Narragansett Bay?, Christine Gardiner, Anna Robuck, Rainer Lohmann
Do Halogenated Natural Products Bioaccumulate In Narragansett Bay?, Christine Gardiner, Anna Robuck, Rainer Lohmann
Senior Honors Projects
In recent decades, a new family of chemical compounds has begun to garner research attention—halogenated natural products, or HNPs. These chemicals are produced by algae, bacteria, worms, and sponges, and many are structurally similar to harmful manmade compounds, such as polychlorinated diphenyls (PCBs), or brominated flame retardants (PBDEs), which are known to cause cancer, reproduction issues, endocrine disruption, and death. While HNPs are produced naturally, they are still considered pollutants because of their bioaccumulative behavior and apparent toxicity.
Currently, there is limited research on their presence and effects, with a few studies from Europe and the Pacific highlighting their importance …
Improving Our Understanding Of Ocean Circulation: A Modeling Study, Nicole M. Flecchia
Improving Our Understanding Of Ocean Circulation: A Modeling Study, Nicole M. Flecchia
Senior Honors Projects
The Gulf Stream is not a rigidly contained ocean current; it curves and meanders in a manner that causes portions of it to go unstable, breaking off to form warm core rings. These rings travel west – due to the earth’s rotation - through the Slope Sea and onto the southern New England shelfbreak, affecting various physical parameters of our coastal waters as well as the biogeochemical and ecological properties (i.e. the ‘health’) of the those waters. Where a warm core ring lands along the east coast and the time of year it appears varies with each ring, causing each …

Remote Analysis Of Grain Size Characteristic In Submarine Pyroclastic Deposits From Kolumbo Volcano, Greece, Clara Smart, D. P. Whitesell, Christopher N. Roman, Steven Carey
Remote Analysis Of Grain Size Characteristic In Submarine Pyroclastic Deposits From Kolumbo Volcano, Greece, Clara Smart, D. P. Whitesell, Christopher N. Roman, Steven Carey
Graduate School of Oceanography Faculty Publications
Grain size characteristics of pyroclastic deposits provide valuable information about source eruption energetics and depositional processes. Maximum size and sorting are often used to discriminate between fallout and sediment gravity flow processes during explosive eruptions. In the submarine environment the collection of such data in thick pyroclastic sequences is extremely challenging and potentially time consuming. A method has been developed to extract grain size information from stereo images collected by a remotely operated vehicle (ROV). In the summer of 2010 the ROV Hercules collected a suite of stereo images from a thick pumice sequence in the caldera walls of Kolumbo …
Detection Of Diffuse Sea Floor Venting Using Structured Light Imaging, Gabrielle Inglis, Clara Smart, Christopher Roman, Steven Carey
Detection Of Diffuse Sea Floor Venting Using Structured Light Imaging, Gabrielle Inglis, Clara Smart, Christopher Roman, Steven Carey
Graduate School of Oceanography Faculty Publications
Efficiently identifying and localizing diffuse sea floor venting at hydrothermal and cold seep sites is often difficult. Actively venting fluids are usually identified by a temperature induced optical shimmering seen during direct visual inspections or in video data collected by vehicles working close to the sea floor. Relying on such direct methods complicates establishing spatial relations between areas within a survey covering a broad area. Our recent work with a structured light laser system has shown that venting can also be detected in the image data in an automated fashion. A structured light laser system consists of a camera and …
Concept Tests For A New Wire Flying Vehicle Designed To Achieve High Horizontal Resolution Profiling In Deep Water, Chris Roman, Dave Hebert
Concept Tests For A New Wire Flying Vehicle Designed To Achieve High Horizontal Resolution Profiling In Deep Water, Chris Roman, Dave Hebert
Graduate School of Oceanography Faculty Publications
Efficiently profiling the water column to achieve both high vertical and horizontal resolution from a moving vessel in deep water is difficult. Current solutions, such as CTD tow-yos, moving vessel profilers, and undulating tow bodies, are limited by ship speed or water depth. As a consequence, it is difficult to obtain oceanographic sections with sufficient resolution to identify many relevant scales over the deeper sections of the water column. This paper presents a new concept for a profiling vehicle that slides up and down a towed wire in a controlled manner using the lift created by wing foils. The wings …

Development Of High Resolution Sea Floor Mapping Tools And Techniques, Gabrielle Inglis, J. Ian Vaughn, Clara Smart, Christopher N. Roman
Graduate School of Oceanography Faculty Publications
There is a persistent need for high resolution photographic and bathymetric maps of the sea floor for many research areas in marine geology, biology and archaeology. This poster will present recent work using high frequency multibeam sonars, stereo vision and structured light laser imaging techniques to create maps with centimeter resolution for these applications. This research involves the development of new image and sonar processing techniques that combat the typical difficulties of imperfect navigation information, limited sensor ranges and adverse environmental conditions associated with using marine robotic vehicles in the ocean. Data for this work has been collected with the …
