Alkalinity Increase in the Arabian Gulf
(2019)Ocean acidification is an issue that is becoming of increasing global concern due to the dramatic impact it has on marine life wellness as well as economy. The Arabian Gulf uses pearl oysters and coral reefs as a major ... -
The ambient soundscape of inland waters in Seattle, Washington: bridge traffic as a source of urban underwater noise pollution?
(2016-06)[author abstract] Increasing human population is adding anthropogenic sources of noise to natural ambient sound levels and threatening marine ecosystem function and viability. Overwater bridges, features of the Seattle ... -
Analysis of Dinoflagellate Species Distribution in the Puget Sound and their Environmental Conditions from 2015-2022
(2022)Marine dinoflagellates live in conditions that if changed, can create dangerous environments promoting harmful algae blooms (HABs). This study investigates the drivers of species distribution and bloom peaks using data ... -
Analysis of Nitrite Concentrations Over Time in the Eastern Tropical North Pacific
(2017-07)The Oxygen Minimum Zone in the Eastern Tropical North Pacific is the largest and most intense in the world. The lack of oxygen causes bacteria to respire anaerobically and therefore changes the nitrogen cycle. Nitrite has ... -
Analysis of subsurface currents in the West Arm of Glacier Bay, Alaska
(School of Oceanography, University of Washington, 2008-06-19)An Acoustic Doppler Current Profiler (ADCP) was used to measure the tides and currents of Glacier Bay. Data points were limited both temporally and spatially, but a general image of the currents at three depth ranges was ... -
Analysis of zooplankton species composition and depth-based habitat preference in Nootka Sound, B.C., Canada
(2015-06)[author abstract] The composition and abundances of zooplankton were studied in Nootka Sound, an estuarine fjord in British Columbia, Canada in winter 2014. Net tows were conducted at ten stations with varying water column ... -
Analyzing drifter designs and data gathering methods in complex estuarine environments
(2015-06)[author abstract] The ability to accurately and consistently map ocean circulation is important for understanding marine processes like sediment transport, pollution distribution, and plankton migration. My study compares ... -
Annual Carbon Export at the North Pacific Axial Seamount
(2019)As anthropogenic CO2 levels rise, it becomes increasingly important to quantify the flux from the surface ocean down into the deep, where it may be sequestered for thousands of years. The goal of this project is to estimate ... -
Anthropogenic CO2 accumulation in the North Pacific Ocean from changes in C/12C of dissolved inorganic carbon
(2009-02-23)Carbon stable isotope data in the Northeast Pacific Ocean was used to track the uptake of anthropogenic carbon dioxide. There are suggestions that the Northeast Pacific has weakened as a sink for anthropogenic carbon ... -
Are fjords sources or sinks of CO2? A study of air-sea CO2 fluxes in Nootka Sound, B.C.
(2015-06)[author abstract] Carbon dioxide, an important atmospheric greenhouse gas, has increased approximately 40% in the past 200 years due to anthropogenic activity. As a result of this, the global carbon cycle has been thrown ... -
Assessing euphausiid homogeneity in Puget Sound scattering layers
(2019)Euphausiids are ecologically important zooplankton in Puget Sound that vertically migrate and can form scattering layers. The depth of euphausiids across sex, species, and length affects what predator-prey interactions ... -
Assessing the Influence of Acoustic Variation on the Acquisition of Bathymetric Surveying Data
(2013-06)[author abstract] The field of hydrographic surveying is inherently important to achieving a true understanding of the world that underlies the vast bodies of water that cover the earth. In this study I will determine the ... -
Assessment of N2 production in anoxic regions of Effingham Inlet, British Columbia
(2010-05)Anerobic processes that reduce fixed nitrogen to N2 gas were determined to be present in the anoxic regions of Effingham Inlet, British Columbia. Within this fjord two sills deter circulation of oxygen rich water from ... -
Assessment of nitrogen removal trends in the Eastern Tropical North Pacific using 15N labeling experiments
(2012-06)[Author's Abstract] Areas of low oxygen in the world’s oceans provide a suitable habitat for bacteria involved in the nitrogen removal process. The expansion of one such area in the Eastern Tropical North Pacific (ETNP) ... -
An Assessment of Noise Pollution Propagated by WSDOT Ferries in the Puget Sound
(2109)Increasing ferry traffic in the Puget Sound and Salish Sea raises concern for marine mammals due to noise pollution. This is not a topic of major environmental concern in the design process for future ferry generations. ... -
Assessment of wintertime carbon flux direction in the fjord system of Hood Canal in Washington
(2018-05-27)The relationship between carbon dioxide and the mechanisms behind its exchange between the ocean and atmosphere benefits the study and understanding of climate change given Carbon dioxide’s behavior as a greenhouse gas and ... -
Automatic recognition of seafloor features in sub-bottom profiles using eigenimages
(2015-06)[author abstract] Sonar is the primary tool used to remotely survey the seafloor. Sub-bottom profilers use pulses of sound to penetrate the seafloor and create an acoustic profile of the seafloor and sub- bottom. The ... -
Bacterial abundances and their relationship to iron around the Galápagos Islands, Ecuador
(2006-03)In an attempt to characterize the influence of an iron source on bacteria around the Galapagos Islands, bacteria were sampled at the surface and at four different depths from the R/V Thomas G. Thompson during 13-15 January ... -
Bacterial Biomass along the Kuroshio Extension
(2013-06)[author abstract] Bacteria are essential for the remineralization of nutrients in the ocean between different energy levels. Therefore, understanding what control bacterial abundance in the ocean is important. This ... -
Bacterial growth rates and bacterivory around the Galápagos Islands
(2006-03)The equatorial Pacific is an HNLC (high-nitrate, low chlorophyll) region, with the exception of the area around the Galápagos Islands, where there is commonly a relatively large standing stock of phytoplankton. In this ...
