Emerging Science and Technology Options in Monitoring Invasive Tunicate Colonization
(2017-11-12)Marine invasive species are a growing problem exacerbated by the evolution and emergence of marine technology and modes of transportation. Current tracking and observation methods of tunicate colonization relies on the ... -
Endocrine disrupting chemical (EDC) accumulation in Puget Sound sediments and the implications for native fish populations
(School of Oceanography, University of Washington, 2008-06-19)Sediments from Glacier Bay and Puget Sound, Washington were analyzed for the presence of natural and synthetic estrogens and progestogens. Glacier Bay had low concentrations and Puget Sound had high concentrations. The ... -
ENSO and Pacific Decadal Oscillation: their effects on basins of the Puget Sound estuary
(2019)Puget Sound in Washington state is one of the largest estuaries in the world and is home to abundant and diverse wildlife and urban communities alike. The different basins of its more 1000 square miles respond uniquely to ... -
Environmental controls on zooplankton composition and distribution in Muchalat Inlet, Nootka Sound, B.C., Canada
(2016-06)[author abstract] This study investigates environmental controls on zooplankton populations within the estuarine Muchalat Inlet fjord basin in Nootka Sound, B.C., Canada. Five stations were sampled ... -
Environmental impact assessment: looking at sediments in Nootka Sound for traces of pulp mill effluent
(2015-06)[author abstract] The production of pulp, a paper product, involves a combination of chemical washes and combustion processes that are known sources of many persistent organic pollutants that can bio-accumulate in the ... -
Environmental influences on the distribution of sediment within a water column at a tidewater glacier, Jorge Montt
(2010-05)The purpose of this study was to determine how certain factors present in the environment helped to direct the distribution of sediment within the water column at the Jorge Montt glacier in Chile. The developing behaviour ... -
Establishing a link between bacterial distribution and nutrient variation
(2010-05-07)The purpose of this research was to study the variation in bacterial communities along with variation in the natural environment. By doing so, it becomes possible to establish connections between different bacteria species ... -
Establishing fluxes of carbon dioxide and a transect of pCO2 during the late fall of precipitation driven Northern fjord
(2016-06)[author abstract] As atmospheric carbon dioxide (CO2) continues to increase beyond 400 ppm, the concerns of how and where the anthropogenic CO2 will cause drastic effects is under intense scrutiny. While the effects on ... -
Establishing paleorecords in the galapagos using hydrogen isotope ratios as a proxy for climate change
(2013-06)[author abstract] Global climate is heavily influenced by the hydrology of the tropical Pacific, which is characterized by a band of heavy precipitation at ~10°N in summer (~3°N in winter) known as the Intertropical ... -
Estuarine circulation in Barkley Sound; observed characteristics and processes
(2010-05-28)In March 2010 hydrographic data was collected in Barkley Sound as a part of a study to help better understand the physical properties and circulation processes within the Sound. The primary goal was to determine how the ... -
Evaluating Changes of the Anthropogenic Carbon Inventory in the Northwestern Pacific using 13C
(2013-06)[author abstract] Carbon dioxide concentrations in both the atmosphere and ocean have been increasing recently due to the burning of fossil fuels. In order to predict and understand future climate the inventory of ... -
Evaluating Video Imagery as a Method for Monitoring Nearshore Ecosystem Change
(2017-07)Documentation, communication, and explanation of the impacts of climate change on the sensitive nearshore ecosystem rely on tools that provide transparency about the technology and accessibility to the data. When used as ... -
Evaluation of Machine Learning Techniques for Estimating Biogeochemical Properties on Seaglider Tracks in the Southern Ocean
(2022)The Southern Ocean is the largest oceanic carbon and heat sink on the planet with complex dynamics at a variety of scales. Reliable, accurate, and high resolution estimates of nitrate and carbonate system parameters ... -
Evaluation of options in producing BASE surfaces used in navigational charting
(2017-07)This study will compare methods in data processing of multibeam SONAR survey data for use in detection of the shoalest (shallowest) and deepest points along a surveyed region for use in charts meant to aid in-port navigation. ... -
An evaluation of the abundance of polycyclic aromatic hydrocarbons in Glacier Bay, Alaska
(School of Oceanography, University of Washington, 2008-06-19)Polycyclic aromatic hydrocarbons are carcinogenic and mutagenic pollutants that settle in sediments, and disrupt the biology of sealife. This study took sediment samples from Glacier Bay, and measured the amount of PAHs ... -
Evidence of modern erosional processes in submarine canyons north of Molokai, Hawaii
(2011-03)The research in this paper is focused on submarine canyons north of Molokai, Hawaii to determine if they continue to be eroded by underwater landslides and sediment flows, or if erosion halted when they were submerged. ... -
Evolution of submarine terraces off Northern Moloka’i, HI
(2023-06)Submarine terraces off Northern Moloka’i, HI, have been understudied. Terraces are vital to our understanding of sea-level changes and terrestrial alterations. One study aimed to identify terraces and evaluate their ... -
Expanded Development of Consumer-level Unmanned Aerial Vehicles for Oceanographic Research
(2019)Unmanned Aerial Vehicles (UAV) are rapidly proving their worth in many fields of science, yet their adop<on in ocean sciences is lacking. UAVs are cost effec<ve vehicles capable of being rapidly deployed and used in ... -
Expanse of the oxygen minimum zone and denitrification in the eastern tropical North Pacific
(2012-06)[Author's Abstract] The oxygen concentrations in the eastern tropical North Pacific (ETNP) are quite anomalous; waters ranging from approximately 300 to 1000 meters have very low amounts of oxygen, some even having no ... -
An experiment to identify levels of triclosan that are harmful to bacteria in Puget Sound.
(2007-05)The commonly used antibacterial substance, triclosan, makes its way into Puget Sound during sewage outfalls. Bacteria, naturally living in the water, might become an accidental target of triclosan. Water samples were ...
