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 ... -
Fine-grained sediment accumulation rates of southern Saratoga Passage
(2010-05-27)The Skagit River is Puget Sound's largest river. This study formed a general idea of sedimentary processes occurring in southern Saratoga Passage of Puget Sound. -
FORCING OF GULF STREAM POSITION AND STRENGTH BY WIND AND OCEAN CIRCULATION
(2017-07)The Gulf Stream (GS) is the western boundary current of the North Atlantic Subtropical Gyre, which in turn is part of the Atlantic Meridional Overturning Circulation (AMOC). As a wind driven gyre, the Gulf Stream is ... -
Forensic geomorphology of Volcan Ecuador, Galapagos: Collapse, lateral eruption or both?
(2006-03)Shield volcanoes such as Hawaii, the Canary Islands, and the Galapagos are known to erode rapidly after they become extinct. This erosion can lead to massive landslides both on land and in the water. Volcan Ecuador is a ... -
Freshwater flux and mixing of a highly glaciated fjord: Glacier Bay, Alaska
(School of Oceanography, University of Washington, 2008-06-19)Drifter buoys were released in six locations in Glacier Bay to determine the amount of freshwater input into the bay. After correcting for tidal and wind activity, the number calculated is 1/5 of the amount predicted. -
The generation and propagation of internal waves in Nootka Sound
(2015-06)[author abstract] The inlets of Nootka Sound, British Columbia provide a favourable area to study internal wave generation and propagation due to their varying bottom topography, the presence of sills and the occurrence ... -
Generation and structural properties of internal waves in Hood Canal
(2018-05-27)Internal waves were first reported by Vilhelm Bjerknes as the phenomenon called “dead water,” and can now be observed all over the world. In Hood Canal, a fjord in the southwestern portion of Puget Sound, internal waves ... -
Geological structure and acoustic properties of sediments in Effingham Inlet
(2013-06)[author abstract] Effingham Inlet is a unique fjord landscape located in Barkley Sound of Vancouver, Canada that was uncovered by glaciers around 15 ka. In this study, multibeam echosounder bathymetric and backscatter ... -
Geology of a hydrothermal upflow zone on the Endeavour Segment, Juan de Fuca Ridge
(2010-05)The upflow zone on the Endeavour Segment, Juan de Fuca Ridge, represents an extinct hydrothermal system that was raised up by faulting, exposing the interior. Submersibles and remotely operated underwater vehicles were ... -
Growing biofuel outdoors in Seattle: effects of natural light level and temperature on marine microalgal culture density and lipid content in contained natural exposure systems
(2015-06)[author abstract] The effects of natural light and temperature on the growth rate, culture density, and lipid content of marine micro algae species Pavlova lutheri and Pavlova sp. were investigated to potentially lend ... -
Heavy metal contamination in Puget Sound and Lake Washington sediments and benthic invertebrates; a focus on the influence of road material on extent of metal concentration
(2019)Heavy metallic elements are found naturally in nature, but have been released into soils, rivers, and bodies of water due to anthropogenic activity, increasing concentrations to levels potentially harmful to human and ... -
Heavy metal contamination in the greater Puget Sound from various anthropogenic point sources; concentrations in the sediment in comparison to marine biota
(2018-05-27)Heavy metals are naturally occurring elements that have a high atomic weight and are usually found in trace levels within the environment, but can become toxic to marine organisms at elevated concentrations. They can enter ... -
Heavy Metal Pollution in Puget Sound Marinas and Shipyards
(2019)As worldwide industrial activities continue to grow, concerns have risen over the varied and potentially harmful effects of heavy metal accumulation in the marine environment. While some of these elements may be necessary ... -
Historical sea level and accommodation zones along Baja California
(2012-06)[Author's Abstract] Change in sea level is an ongoing process which alters the coastal ecosystem on a continuous basis. The physical changes in the world’s coastal ecosystem due to sea level change have occurred many times ... -
How Edge Effects in Eelgrass Habitats Impact Organism Abundance and Diversity in the Puget Sound
(2019)Habitat transitions occur all over the globe. They can be seen in both terrestrial and marine environments and produce influential edge effects. In the Puget Sound, eelgrass habitats are commonly seen with abrupt habitat ... -
How The Environmental RNA Signature of Nitrate Reductase Can Be Used as a Predictor for Phytoplankton Distribution
(2021)With anthropogenic climate change altering the ocean, it is critical to understand what variables control phytoplankton distribution so we can predict how distributions will be altered as result of climate change. This ... -
Hydroaccoustic pinging as a diver tool for underwater navigation in surveying Puget Sound Eelgrass (Zostera marina) densities
(2016-06)[author abstract] Advances in technology have led to a change from data limited, direct observations to much numerous, more remote data. Despite this trend direct observations are still an important source of information ... -
Hydrographic study on the effect of Rumble III on the thermohaline structure and circulation
(2010-01-14)Isotherm (temperature), isohaline (salinity) and isopycnals (density) were plotted for the Rumble III volcano. The data were gathered through measuring current velocity, CTD in vertical transects, and the concentrations ...
