Thermal Analysis Of Borosilicate Glass For Its Biological Applications, Gregory Humble

Symposium of Student Scholars

Borosilicate glass doped with varying wt% of cerium oxide is investigated for biological applications. Thermal studies of each formulation were conducted using an SDT Q600 differential scanning calorimeter. 30mg samples of 350 - 425 μm particle size of each type of glass were heated to 1200°C in order to obtain the glass transition, crystallization, and melting temperatures. Samples were then heated to 900°C at several heating rates, ranging from 2°C/min to 100°C/min, then compared against each other as well as against an undoped borosilicate glass.

The Effect Of Nitrate On The Release Of Glucose Into The Hemolymph Of Crayfish, Procambarus Clarkii, Alec R. Flores, Lee Kats, David Green, Gary Bucciarelli

Seaver College Research And Scholarly Achievement Symposium

Pollutants can change the behaviors of invertebrate stream animals. The level of one common pollutant, nitrate (NO3), has been rising in many local rivers and streams throughout the United States due to increases in anthropogenic sources. Nitrate, heavily regulated for its toxic effects to human health, namely the aiding in the development of cancer, also dangerously affects aquatic species by converting oxygen-carrying pigments to forms that are incapable of carrying oxygen. To understand the stress effects of ambient nitrate exposure on P. clarkii, we collected hemolymph samples from red swamp crayfish (Procambarus clarkii) over a 48-hour period after exposure to …

Movements Of Sub-Adult Chinook Salmon (Oncorhynchus Tshawytscha) In Puget Sound, Washington, As Indicated By Hydroacoustic Tracking, Anna Kagley, Joseph Smith, Kurt L. Fresh, Kinsey Frick, Thomas P. (Thomas Peter) Quinn

Salish Sea Ecosystem Conference

Alternative forms of migratory behavior can have substantial consequences for the growth, survival, and fitness of the individuals involved. Salmonids vary in the tendency of individuals to migrate to marine waters (anadromy) or remain in freshwater habitats. In addition, substantial variation in migratory patterns can exist among anadromous and resident species. This talk summarizes our use of hydroacoustic telemetry to investigate the movement patterns of anadromous Chinook salmon Oncorhynchus tshawytscha remaining in the marine waters of Puget Sound after ocean entry rather than continuing out to the coastal waters of the North Pacific Ocean, as is typical of the species. …

Variable Marsh Resilience To Stress Offers Clues To Climate Change Adaptive Management, Roger Nathan Fuller, Katrina L. Poppe, John M. Rybczyk, Eric Grossman, Chad Stellern

Salish Sea Ecosystem Conference

In Puget Sound’s Stillaguamish estuary, tidal marshes exhibit evidence of multiple stressors that affect their vulnerability and provide insight into adaptive management opportunities to enhance their resilience. Despite high accretion rates, some marsh areas have receded by 10m/yr since 1964. Sources of stress include overgrazing by snow geese, high soil salinities, insect attacks, and changes in flow and inundation patterns. These interact with winter vegetation structure, sediment composition, and wave exposure to result in spatially variable marsh resilience. Some marshes are receding quickly, some slowly, and others are minimally affected. In the context of climate change, with potentially substantial near-term …

An Inventory Of Environmental Governance In The Salish Sea, Laurie D. Trautman

Salish Sea Ecosystem Conference

How is the natural environment of the Salish Sea governed? The fact that the Salish Sea is bifurcated by a national border has inhibited our ability to answer this question. Indeed, the Salish Sea involves not only two national governments, but also a multitude of both state and non-state actors, which exist across scales, and interact in different frameworks (i.e. First Nations/tribes often seek only to negotiate with federal, rather than state/provincial governments). Environmental governance in the Salish Sea also encompasses informal modes of interaction involving public and private interest groups, social movements and community stakeholders, in addition to traditional …

A Long-Term Phytoplankton Monitoring Program For Central Puget Sound Using Particle Imaging, Gabriela Hannach, Lyndsey M. Swanson

Salish Sea Ecosystem Conference

Puget Sound is a large and highly productive estuarine system that is vulnerable to climate change and anthropogenic impacts from a growing population. King County operates an exceptionally comprehensive, long-running monitoring program designed to assess water quality in the Puget Sound Central Basin. Data are collected year-round for a suite of physical, chemical, and biological parameters. Phyoplankton monitoring using traditional methods was added to the program in 2008 to address a significant biological data gap at the lower trophic level. Since acquisition of a FlowCAM particle imaging system in 2014 the program is generating a more extensive and robust dataset …

Skagit Climate Science Consortium: Using Local Polling To Provide Relevant Science, Carol B. Macilroy, Larry Wasserman

Salish Sea Ecosystem Conference

The Skagit Climate Science Consortium (SC²) and the Yale Project on Climate Change Communication partnered to conduct a public opinion poll in the spring of 2015 regarding Skagit County resident’s attitudes and perceptions regarding global warming. The effort, part of Yale’s renown 6 America’s Project, also is providing SC² critical information to help understand local concerns and beliefs about climate change in order to better provide relevant and timely climate science to a broader Skagit community. This presentation will provide an overview of SC²’s theory of change regarding the role of climate science in supporting …

Virtual Simulations Of Potential Vessel Discharges In Puget Sound And The Puget Sound No Discharge Zone, Teizeen Mohamedali, Mindy Roberts, Amy Jankowiak

Salish Sea Ecosystem Conference

The Washington State Department of Ecology (Ecology) evaluated the potential transport, dispersion and dilution of potential vessel sewer discharges within the draft proposed Puget Sound No Discharge Zone (NDZ). These model simulations included potential vessel sewer discharges at six locations in Puget Sound along major shipping routes. Results are presented as virtual animations of surface concentrations, allowing us to visualize the transport, circulation, and dilution of these discharges over the course of several days.

Ecology and Pacific Northwest National Laboratory jointly developed a three-dimensional hydrodynamic FVCOM (Finite Volume Coastal Ocean Model) computer model of the Salish Sea. This model is …

Volunteer-Assisted Monitoring Of A Significant Private Bulkhead Removal, Jeffrey Adams, Brenda Padgham, Jason David Toft, Kyra O'Neil, Kate Litle

Salish Sea Ecosystem Conference

Monitoring efforts to restore physical and biological functions along developed shorelines can take many forms and be influenced by monitoring goals, the scope and scale of the project, and available resources. The Powel project in Port Madison on Bainbridge Island, Washington, had regional significance because of its scale (removing 1544 lineal feet of armor), the diversity of types of armor and shoreline, and its private ownership, but it lacked the funding to support a broad, long-term monitoring program. Not willing to let the opportunity pass without some effort to gather as much appropriate information as possible about the impact and …
