A Five Year Look At The Impacts Of Ph Seasonally And Spatially Within Possession Sound, Maxwell Bauccio-Teschlog Apr 2022

A Five Year Look At The Impacts Of Ph Seasonally And Spatially Within Possession Sound, Maxwell Bauccio-Teschlog

Salish Sea Ecosystem Conference

The ability for an ecosystem’s organisms to adapt and thrive is dependent on the water chemistry. Capabilities for adaptation to the ever-changing environment are affected by the pH, or the acidity, of the water. Microorganisms, which are the foundation for a healthy ecosystem, are impacted by the pH of the water, and thus their ability to thrive depends on it. Globally, the pH of the ocean is decreasing as a result of ocean acidification caused by increasing anthropogenic CO2 emissions. Within the Salish Sea, which is home to an abundance of life, lies Possession Sound, located off the shores of …

West Whidbey Island Beach And Bluff Change Between 2015, 2018, And 2021 From Boat-Based Lidar, Amanda Hacking

Salish Sea Ecosystem Conference

The Washington State Department of Ecology Coastal Monitoring & Analysis Program (CMAP) collected high-resolution coastal topographic data along west Whidbey Island with boat-based lidar in 2015, 2018, and 2021. The high-density data acquired along the beach and bluff enabled detailed measurements of morphology and the generation of 0.5-meter digital elevation models (DEMs). The overlap between all three datasets, from Point Partridge north to West Beach County Park, is a 9-km reach dominated by feeder bluffs along the updrift end of a 23-km drift cell with relatively high wave exposure. The DEMs are compared along this updrift reach to reveal patterns …

Optimizing A Passive Tracking Solar Panel System, Adrian Salazar-Rivera, Ryan Pickelman, Angela Douglass Apr 2022

Optimizing A Passive Tracking Solar Panel System, Adrian Salazar-Rivera, Ryan Pickelman, Angela Douglass

Scholars Day Conference

For a solar panel to function efficiently, it must turn to face the sun throughout the day. Usually, an electronic device rotates a solar panel. In this experiment, hourly rotation of the panel was achieved through contraction of a shape memory alloy (SMA) and a gear system. A Fresnel lens directed the sun's rays onto the SMA causing it to contract. A delayed reset system was built to turn the panel from west to east at the end of the day. In addition, this project investigated different materials to properly heat and cool the SMA within the plexiglass housing apparatus. …

A Fractal Geometry For Hydrodynamics, Jonah Mears Apr 2022

A Fractal Geometry For Hydrodynamics, Jonah Mears

Scholars Day Conference

Experiments have shown that objects with uneven surfaces, such as golf balls, can have less drag than those with smooth surfaces. Since fractal surfaces appear naturally in other areas, it must be asked if they can produce less drag than a traditional surface and save energy. Little or no research as been conducted so far on this question. The purpose of this project is to see if fractal geometry can improve boat hull design by producing a hull with low friction.

Quantitative Analysis Of The Maximum Rate And Minimum Duration For A 200 Km Stepwise Retreat Of The Bindschadler Ice Stream At ~11.5 Cal Kyr Bp, Matthew E Kratochvil Apr 2022

Quantitative Analysis Of The Maximum Rate And Minimum Duration For A 200 Km Stepwise Retreat Of The Bindschadler Ice Stream At ~11.5 Cal Kyr Bp, Matthew E Kratochvil

LSU Master's Theses

Small-scale morainal ridges on the middle continental shelf of the Whales Deep Basin partly record the rapid opening of a 200-km grounding line embayment slightly after ~11.5 cal kyr BP. The overlapping pattern of backstepped moraines indicates that the grounding line oscillated back and forth during the retreat. Published sediment fluxes were combined with new sediment volume mapping of the moraines to infer the rates at which the grounding line retreated. The analyses indicate that the rates of grounding line retreat on the eastern flank of the embayment ranged from ~490 m a-1 to 1,300 m a-1. …

Hatchery Release Strategy Effects On Production Outcomes For Chinook And Coho, Sam James Apr 2022

Hatchery Release Strategy Effects On Production Outcomes For Chinook And Coho, Sam James

Salish Sea Ecosystem Conference

Salmon hatcheries face the challenging task of developing release strategies that attempt to maximize survival and minimize risk to wild populations. Release strategies refer to the size at release, timing of release, nature of release (i.e. forced or volitional), number of releases, release location, and the use of acclimation facilities prior to release. We led an extensive review of hatchery release strategies and how they can be used as a management tool to influence production outcomes (i.e. survival, catch, and return ages). The review consisted of three components: 1) a systematic review of the literature from BC and the western …

Utilizing New Pit Tag Technology To Assess Juvenile Chinook Migration Patterns, Residence Time, And Survival In The Lower Green River., Chris Gregersen Apr 2022

Utilizing New Pit Tag Technology To Assess Juvenile Chinook Migration Patterns, Residence Time, And Survival In The Lower Green River., Chris Gregersen

Salish Sea Ecosystem Conference

The highly altered lower Green river subbasin has been the focus of intense salmon habitat planning and restoration efforts since the listing of Puget Sound Chinook in 1999. Monitoring juvenile chinook migration and life history dynamics has been critical for tailoring habitat restoration in the Green River. In the lower Green subbasin, however, juvenile salmon population monitoring using screw traps has proven to be difficult due to low gradient and water velocities. Meanwhile, traditional monitoring methods (e.g., electrofishing and seining) cannot accurately quantify residence time or survival rates. Given the large financial investments of habitat restoration in the lower Green, …

Assessing Futures Of Two Cowichan River Pacific Salmon Species, Chinook And Coho, Using Scenario Analysis For Cumulative Effects Assessment, Dr. Arman Ospan, Johannes J. Feddema, Andrea Locke

Salish Sea Ecosystem Conference

We assessed futures of the Cowichan River’s anadromous Chinook and Coho salmon populations using a proposed methodology for Cumulative Effects Assessment. First, we examined linkages between salmon survival and effect drivers; we built quantitative models to predict changes in salmon survival in response to changes in effect drivers; created scenarios of divergent futures for each effect driver; and, by applying the models, projected salmon survival for each scenario. We conducted assessment for both early freshwater and marine environments. In fresh water, we focused on two main factors: streamflow and stream temperature, and two main drivers: land use and climate change. …

Modeling The Effects Of Climate Change On Peak Flows In The Nooksack River, North Cascades, Wa, Evan Paul Apr 2022

Modeling The Effects Of Climate Change On Peak Flows In The Nooksack River, North Cascades, Wa, Evan Paul

Salish Sea Ecosystem Conference

The Nooksack River in northwest Washington State provides freshwater for agriculture and industrial use and serves as a vital habitat for endangered salmon, a resource that is of cultural and economic importance to the Nooksack Indian Tribe. Historically, peak streamflows in the 2300 sq-km Nooksack basin are driven by rainfall in the fall and early winter. Global climate models (GCMs) project an increase in air temperatures for the Salish Sea region, and previous modeling within the Nooksack basin projects a reduction in snowpack extent through the 21st century and an increase in winter streamflow magnitude. As more landscape becomes exposed …

Improving Salmon Access To Inland Habitat Can Also Reduce Risk To Human Safety And Property, Ken Cousins Apr 2022

Improving Salmon Access To Inland Habitat Can Also Reduce Risk To Human Safety And Property, Ken Cousins

Salish Sea Ecosystem Conference

Salmon are not only keystone species, but are also culturally and economically critical, supporting large tribal, commercial, and recreational fishing industries. Transportation infrastructure can significantly impact salmon, especially where road crossings impede their free movement. Modifying stream crossing infrastructure to restore salmon access to inland habitat is a major (albeit expensive) priority throughout the region. Progress in this area will require broadening stakeholder support and financing options. We must expand our understanding of the value of improving stream crossings to include not only ecological costs, but also conventional risks (e.g., localized flooding, transportation disruptions) arising from disrupted stream flows. Earth …

Modeling The Effects Of Projected Climate Warming On Stream Temperatures In The Stillaguamish River Basin, Emily Smoot Apr 2022

Modeling The Effects Of Projected Climate Warming On Stream Temperatures In The Stillaguamish River Basin, Emily Smoot

Salish Sea Ecosystem Conference

The Stillaguamish River watershed is a snow-and-rain mixed basin in northwestern Washington, with snowmelt being important for sustaining spring and summer streamflow and buffering stream-temperatures. Elevations in the 1700 sq-km Stillaguamish basin reach roughly 2000 m that sustain a historical snowpack above about 1000 m. Previous basin-specific modeling projected that snowpack will retreat to higher elevations and summer stream temperatures will increase, reaching both embryo lethality (16 °C) and adult lethality (22 °C) by 2075 in the North and South Forks in the Stillaguamish River. Stream temperature increases are of significant concern because of the threatened Chinook salmon population, which …

Occurrence And Fate Of 6ppd-Quinone In Urban Receiving Waters, Dr. Edward Kolodziej Apr 2022

Occurrence And Fate Of 6ppd-Quinone In Urban Receiving Waters, Dr. Edward Kolodziej

Salish Sea Ecosystem Conference

In the U.S. Pacific Northwest, coho salmon, (Oncorhynchus kisutch), annually exhibit acute mortality upon stormwater exposure when adult salmon migrate to urban and near urban creeks to reproduce. We recently linked these mortality events to “6PPD-quinone”, a highly toxic transformation product of a common industrial antioxidant chemical 6PPD that is ubiquitously used in vehicle tires. These results reveal unanticipated risks of tire rubber antioxidants to an important aquatic species and imply toxicological relevance for widely dissipated tire rubber residues. Management of roadway runoff in general, and 6PPD/6PPD-quinone specifically, will be a clear priority for maintenance of ecosystem health and function, …
