The effects of sill-circulation on zooplankton patchiness
(2015-06)[author abstract] Fine scale zooplankton patchiness is an important component of similarly scaled trophic interactions. There are biological and physical drivers of patchiness--this study focused on the physical component, ... -
The effects of suspended glacial sediments on light attenuation and primary productivity in Glacier Bay National Park, Alaska
(School of Oceanography, University of Washington, 2008-06-19)Glacial flour, or the sedimentation resulting from glacial runoff, attenuates light and therefore productivity in the sea. Measurements of primary productivity and light were taken in Glacier Bay to determine the effect ... -
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 ... -
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 ... -
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. ... -
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 ... -
Exploring the spatial variation of tides for seafloor mapping data corrections
(2016-06)[author abstract] Acquisition of high definition hydrographic survey data has made several advancements in correcting for errors during signal acquisition. This potential error is associated with vessel position, ship ... -
Extent of the oxygen minimum zone in the eastern tropical North Pacific
(2012-06)[Author's Abstract] The Eastern Tropical North Pacific contains a vast layer of water with very low oxygen content, or oxygen minimum zone (OMZ.) To determine if the OMZ has increased in size, the author measured oxygen ... -
The fate of biologically produced methane in an anoxic fjord in British Columbia
(2013-06)[author abstract] An increase of methane gas in the atmosphere has been shown to exacerbate climatic changes, much more so than an increase in carbon dioxide. This study examined an anoxic fjord in British Columbia, ... -
Fetch-limited wave growth in Nootka Sound
(2016-06)[author abstract] Ocean waves are generated at every coast line in the world. Wave generation and growth depends on wind. One hypothesis explored by this study is fetch-limited wave growth. Fetch is how far wind travels ... -
Finding ‘Good Friday’ An explorative study into the sedimentary structures left from the Good Friday tsunami
(2013-06)[author abstract] In 1964 the small logging town of Port Alberni, Vancouver Island B.C., was struck by the tsunami generated by the Good Friday earthquake originating near Anchorage, Alaska. This is Canada’s most destructive ...
