Investigating physical drivers of phytoplankton bloom initiation in the Northern Gulf of Alaska

Creator:: Ballantine, Kaleigh
Abstract:: The spring bloom is a key oceanic phenomenon in the Northern Gulf of Alaska (NGA), where it supports the regional ecosystem, fisheries, and CO2 sequestration. Despite its significance, mechanisms that trigger NGA blooms are still debated, largely due to a lack of sufficient data from late winter through spring. New...

Opportunities and Limitations in Achieving Real-Time Observation of Soil Nitrate

Creator:: Auld, Ryan A.
Abstract:: There are many possible benefits that can arise from the ability to take real-time measurements of soil water nitrate concentrations in a field, from ecological to agricultural to industrial reasons. In order to achieve this, we adapted a NitraLED sensor with a ceramic porous cup in order to allow diffusion...

Design and Implementation of a Modular Ocean Drifter Kit

Creator:: Green, Austin
Abstract:: Ocean Drifters are a low-cost and easy-to-use platform that are commonly used for studying ocean currents. With added interest in studying the ocean, emphasis has been taken to make it more accessible. A pilot course focused on introducing the topic of ocean sensing was announced. The HC 407 course will...

An Improved Chemical Kinetic Model Reduction in pyMARS for Liquid Propellants

Creator:: Moore, Cailin J.
Abstract:: The aerospace industry uses chemical kinetic models when designing propulsion systems to acquire specific details about the rate of chemical reactions, heat release, and combustion stability. These models, however, are too large and stiff to be useful as they can take weeks to run computations on. The pyMARS python package...

Two Advances in Practical Alternative Energy: Thermotolerant Hydrogenase Concentration and Methane Hydrate Grain Size Proxies.

Creator:: Sullivan, Nichole D.
Abstract:: Methane hydrates and biohydrogen are two disparate subjects that are of interest in the growing field of alternative energy research. However, before commercial use becomes a viable option, each has challenges that need to be overcome. Methane hydrates require large investments of time and capital to locate. In this thesis,...

Preliminary Evidence that the Microbial Community may Produce Aliphatic Constituents and Induce Soil Water Repellency as a Response to Desiccation

Creator:: Chilcote, Emma T.
Abstract:: Soil water repellency is one cause of rill soil erosion and overland flow that results in the loss of fertile topsoil. Previous research suggests that since microbial growth depends on temperature/moisture and follows diurnal and seasonal cycles, a biological mechanism would be able to explain the observed seasonality and climate...

Spectral Analysis of Upper Ocean Surface Wave Structure using χSOLO Floats in the Bay of Bengal

Creator:: Ball, Matthew S.
Abstract:: Surface waves play a vital role in air-sea interactions, and being able to easily measure them in-situ validates and improves predictive models. Here, we diagnose surface wave properties in the Bay of Bengal using modified vertical SOLO II profiling floats, which are regularly used as part of the Argo ocean...

Ocean Acidification Carryover Effects from Oyster Broodstock to Larvae

Creator:: Klein, Victoria G.
Abstract:: Atmospheric carbon dioxide has increased by approximately 40% since preindustrial times from 280 ppm (parts per million) to 400 ppm. The rise in Pco₂ is causing the ocean to become more acidic due to the uptake of carbon dioxide by the water, termed “ocean acidification”. As the Pco₂ in the...

Effects of Xanthohumol on Biomarkers of Metabolic Syndrome in Obese Rats

Creator:: Moreno Luna, Arlyn Y.
Abstract:: Flavonoids are a large family of compounds synthesized by plants that have a common chemical structure. It is believed that the health effects of fruits and vegetables are primarily due to dietary flavonoids content. Current research indicates that dietary flavonoids show promise for mitigating and/or preventing chronic conditions associated with...

Characterization and spatial distribution of particulate organic matter in the Arctic Ocean

Creator:: Corvi, Elizabeth R.
Abstract:: Water samples from the Arctic Ocean were analyzed in order to assess the present nature of particulate organic matter and investigate the effect of climate-driven changes on the ecology of the region. 661 individual surface water samples and 216 samples from CTD casts were collected from the Bering, Chukchi, and...
