Technology in Support of Shoreline Surveys for Characterizing Spatial Complexity
(2018-05-27)There are numerous issues related to the management of shoreline development in Puget Sound. As shoreline property owners armor and protect their coastal property from erosion and slope failure, many natural processes are ... -
Temperature control and encystment of the toxin- producing dinoflagellate, Alexandrium catenella, in Puget Sound, Washington
(2007-05)Alexandrium catenella is a dinoglagellate which produces a neurotoxin, and is prevalent in Puget Sound. A. catenella represents a serious risk to consumers and farmers of shellfish. This study examines the environmental ... -
Temperature mediated hypoxia tolerance in a Northeastern Pacific Crab
(2018-05-27)Hypoxic events are increasing in frequency and are often linked to mass mortalities, habitat compression, and re-distribution of marine species. While organismal responses to hypoxia are a growing area of research, few ... -
Temporal and comparative variability of Iron and Carbon Dioxide of Loihi Seamount hydrothermal systems
(2011-03-03)Hydrothermal systems are visible representations of geological processes at work. Since their discovery, studies have shown them to be remarkable natural features with unique properties, venting fluids at extreme temperatures ... -
Temporal changes in venting at Brothers volcano, as indicated by backscatter and oxidation-reduction potential
(2010-01-15)CTD-O, light backscatter and oxidation-reduction potential data were obtained for the hydrothermal plumes of the Brothers volcano. The data was compared to 2002 and 2007 datasets. Taken together, the data indicate that the ... -
Thought-Provoking and Interactive Visual Outreach: a non-traditional approach to science communication through gaming
(2022)Traditional scientific writing and education can be hard to engage with and inaccessible. This project evaluates whether a video game about determining the age of hydrothermal vents is more engaging and informative as ... -
Tidal Energy Resource Characterization in Alberni Inlet, B.C.
(2013-06)[author abstract] Tidal energy is a relatively new idea in renewable energy’s for coastal communities. Tides ebb and flood each day and transport a vast amount of water but the movement can be quite slow in the open ... -
Tidal flow over a sill in Muchalat Inlet, Nootka Sound, and the resultant mixing processes
(2015-06)[author abstract] The tidal flow over Williamson Sill, situated in Nootka Sound, is analyzed by reviewing the changes in the density and velocity field across the sill and over the tidal cycle. The density is calculated ... -
TSUNAMI WAVE PROPAGATION THROUGHOUT THE PUGET SOUND
(2019)Tsunamis are commonly caused by submarine earthquakes. An earthquake along the Cascadia Subduction Zone has the potential to create a tsunami that could enter the Straits of Juan de Fuca and propagate throughout the Puget ... -
Understanding the Long-term Tidal Modulation on Methane Bubble Emissions at Southern Hydrate Ridge using Acoustics
(2019)Methane release from seafloor reservoirs is thought to have caused paleo-climate warming and have the potential to accelerate global warming. Methane reservoirs along the upper continental slope are especially susceptible ... -
Underway O2/Ar-estiment net community production across the Kuroshio Extension and impact on winter pCO2 drawdown
(2013-06)[author abstract] Continuous and discrete O2 and O2/Ar measurements were sampled during a late winter transect across the Kuroshio Extension (~30ºN 146ºE to 41ºN 150ºE). Average saturation values for O2 and O2/Ar were found ... -
Uptake of Anthropogenic CO2 and its Effect on Recent Changes of Calcite and Aragonite Saturation in the Northern Pacific from 2006-2015
(2021)As one of the largest carbon sinks in the world, the ocean takes up a large portion of carbon dioxide in the atmosphere. As described through seawater-atmospheric equations, the pH of the ocean has significantly decreased ... -
Using an anisotropic semivariogram of acoustic backscatter intensity to determine the effects of river and tidal forces on the spatial structure of the Gold River delta
(2015-06)[author abstract] River deltas are productive, fast changing landscapes that not only provide a habitat for marine life, but provide an ideal environment for researchers to study changing environmental conditions. This ... -
The value of drifters for modeling fine scale circulation around manmade structures of the shoreline
(2018-05-27)For this project, a data integration plan for the development of a simple mathematical model to show fine scale circulation around manmade structures was designed utilizing Davis-Star drifters. A simple field test determined ... -
Variability In Bacterial Biological Processes At the Tica Vent (9° N) On The Eastern Pacific Rise Using Peptide Analysis
(2021)The purpose of this study is to observe and determine how proteins vary near hydrothermal vents over a period of 9 months. Microbial communities found at hydrothermal vents thrive off the chemicals released from the ... -
Variability in zooplankton distribution at cyclone Enakai in the lee of the Hawaiian Islands
(2011-03)Enakai, a cyclonic eddy, formed in the lee of the Hawaiian Islands and was observed in NAVOCEANO satellite imagery during the week of 30 Oct. 2010. This study examines the physical, chemical and biological processes taking ... -
Variation in phytoplankton abundance along a transect of the Kuroshio
(2013-06)[author abstract] Phytoplankton abundance levels are an important factor in the world’s oceans because they directly correlate to productivity as well as contribute to the global carbon export cycle. Phytoplankton abundance ... -
Variations in seafloor depth estimates under different swath-width characteristics of submarine structures in the California Borderlands
(2016-06)[author abstract] The California Continental Borderland region off the coast of Southern California is home to many types of geological features on the seafloor (aka. submarine structures) that have resulted from movement ... -
Variations of fin whale vocalizations in the Northeast Pacific and the effects of environmental parameters on acoustic sensitivity
(2016-06)[author abstract] Declines in fin whale populations have instigated significant interest regarding their life history, feeding patterns, mating habits, and migration. Our current lack of understanding could be remediated ... -
Vertical distribution of microplastics in Hood Canal and Main Basin, Puget Sound, Washington
(2019)Microplastics have been an increasingly important pollutant and area of research over the past 50 years. Although microplastics threaten marine ecosystems in various ways, little is known about their sink, vertical ...
