Salish Sea Ecosystem Conference
After decades of debate, planning, and environmental impact studies, the largest planned dam removal project in history was conducted on the Elwha River in Washington State, USA, from 2011 to 2014. Because this was such a unique and unprecedented project, the planning, implementation, and monitoring has occurred over 30 years and required diverse expertise across multiple stakeholders. This knowledge portfolio required that individuals and organizations with different missions collaborate effectively to ensure a successful project. The story of this river, with rugged headwaters, protected wilderness, legendary and culturally important salmon runs, and two hydroelectric dams whose placement marshaled wholesale socioeconomic …
Sea Lice Infection Rates On Juvenile Chum Salmon In A Salish Sea Fjord With No Atlantic Salmon Net Pens, Micah Wait, James Fletcher, Adrian Tuohy
Sea Lice Infection Rates On Juvenile Chum Salmon In A Salish Sea Fjord With No Atlantic Salmon Net Pens, Micah Wait, James Fletcher, Adrian Tuohy
Salish Sea Ecosystem Conference
In 2017, Wild Fish Conservancy documented sea louse (Lepeoptheirus salmonis) infection rates on juvenile chum salmon (Oncorhynchus keta) in the nearshore waters of Hood Canal, WA. Transmission of sea lice from the adult fish captive in salmon farms to wild outmigrating juvenile salmon has been posited as a primary impact of Atlantic salmon (Salmo salar) open net pen farming in the Salish Sea. Hood Canal is an isolated fjord that makes up the westernmost arm of Puget Sound. There are no open net pen Atlantic salmon farms in Hood Canal, sampling here should establish rates of sea lice infection on …

Salish Sea Ecosystem Conference
The increased frequency, duration and geographic extent of toxic Alexandrium blooms in Puget Sound presents new challenges of how to best allocate resources available for toxin monitoring of shellfish in order to protect human health. Monitoring plans are typically based on shellfish toxicity patterns from the recent past; however, the increasing trend in Alexandrium blooms means that managers are chasing a moving target. With projected future changes in global and regional climate, the risk of toxic Alexandrium blooms is expected to increase. Through funding from NOAA’s Coastal and Ocean Climate Applications Program, we are developing a harmful algal bloom (HAB) …
An Overview Of The Salish Sea Model: Existence Of Reflux Mixing And Recurring Hypoxia, Tarang Khangaonkar, Adi Nugraha, Wenwei Xu, Wen Long, Laura Bianucci, Anise Ahmed, Teizeen Mohamedali, G. J. Pelletier, Cristiana Figueroa-Kaminsky

Salish Sea Ecosystem Conference
An improved version of a diagnostic hydrodynamic and biogeochemical model (nutrients, phytoplankton, carbon, dissolved oxygen, pH) of the Salish Sea has been developed with the ability to simulate characteristic circulation and water quality features. Notable improvements include expansion of the model domain beyond the Salish Sea, encompassing Vancouver Island and out to the continental shelf boundary. In this talk we present an overview of the model setup describing the model domain coverage, modeling framework, development of boundary conditions, and tidal, riverine, wastewater, and meteorological inputs. Ability of the model to reproduce known circulation features within the Salish Sea is highlighted. …
Uptake And Trophic Changes Of Pbdes In The Benthic Marine Food Chain, Brenda Burd, Chris Lowe, Carmen Morales, Peter Ross
Uptake And Trophic Changes Of Pbdes In The Benthic Marine Food Chain, Brenda Burd, Chris Lowe, Carmen Morales, Peter Ross
Salish Sea Ecosystem Conference
We examine the influence of sediment factors on uptake of PBDEs into marine deposit and filter feeders, and transfer to higher trophic levels. Sediment PBDEs increase with %toc, AVS, organic flux, and fines. As a result, coarser, less organic sediments in JdF have lower [PBDEs] than the southern SoG. Sediment feeder [PBDE] variance was best explained by AVS>[PBDEs]>%TOC>OC flux. Therefore, increasing organic input and burn-down, and sediment PBDEs enhance tissue PBDEs. Dry weight PBDE accumulation (tissue/sediment) in sediment feeders decreased with increasing sediment PBDEs, resulting in tissue dilution at sediment concentrations >10,000pg/g in urban harbours. PBDE accumulation …
Introduction To Challenges And Solutions For Shoreline Armor Removal And Design Of Soft Shore Protection, Jessica Cote, Kathryn E. Ketteridge
Introduction To Challenges And Solutions For Shoreline Armor Removal And Design Of Soft Shore Protection, Jessica Cote, Kathryn E. Ketteridge
Salish Sea Ecosystem Conference
Along coastlines all over the world, land use development has created a need for holding the shoreline in a static position or at least minimizing the dynamic movement of the shoreline. Intense development along the shorelines of the Salish Sea from the 1950s to the 1970s was conducted with limited regulatory oversight or understanding of the cumulative impacts that housing, transportation corridors and other infrastructure would have on the marine environment. Over the last couple of decades it has become widely understood that the practice of using hard armor (timber walls, concrete walls and rockeries) to stabilize shorelines has degraded …
Evaluation Salish Sea Marine Bird Indicators With Insights From Recent Research By Professional And Citizen Scientists, Scott F. Pearson, Martin G. (Martin George) Raphael
Evaluation Salish Sea Marine Bird Indicators With Insights From Recent Research By Professional And Citizen Scientists, Scott F. Pearson, Martin G. (Martin George) Raphael
Salish Sea Ecosystem Conference
Marine birds are often viewed as good ecological indicators because they are relatively well studied and time-series data are often available, our understanding of their population biology is often extremely high, some species are tightly linked to their prey resources and, as upper trophic predators, they offer an integrative view of the dynamics at lower levels of the food web. In 2014, at-sea abundance and trends of the rhinoceros auklet, pigeon guillemot, marbled murrelet and scoters were collectively selected by the Puget Sound Partnership as indicators of the health of the Puget Sound marine food web. Long-term trends for these …
