Salish Sea Surface Currents: Real-Time Velocities From Hf Radar, Richard Dewey, Rich Pawlowicz, Mike Morley, Manman Wang
Salish Sea Ecosystem Conference
Ocean Networks Canada has operated Salish Sea CODAR high-frequency (HF) surface radar systems for monitoring surface currents since 2012. The network of antennae continues to grow, with four arrays now deployed in the southern Strait of Georgia, two more planned for the Strait of Juan de Fuca, and several more installed and planned along BC’s northern coast. These arrays provide hourly maps of surface currents. In the Strait of Georgia, where the Fraser River and ocean tides meet, there are complex surface current patterns that vary under seasonal river and wind conditions. Data are used to understand the circulation, validate …
Challenges And Opportunities For Marine Spatial Planning In The Salish Sea: Learning From Other Jurisdictions, Ross Jameson, Alexandra Barron, Sabine Jessen
Challenges And Opportunities For Marine Spatial Planning In The Salish Sea: Learning From Other Jurisdictions, Ross Jameson, Alexandra Barron, Sabine Jessen
Salish Sea Ecosystem Conference
The Salish Sea is a tremendously dynamic, diverse, and ecologically significant inland sea. It has supported indigenous communities for millennia and is now one of the most heavily used coastlines in the world. Increasing industrial use has resulted in declining biodiversity and ecosystem health. As we continue to see increases in human activities and escalating impacts from climate change on marine ecosystems, and associated declines in marine biodiversity and ecosystem health, Marine Spatial Planning (MSP) is becoming an increasingly important tool to ensure sustainable use of our coastal and marine resources, for generations to come. However, MSP is a resource …
Turning The Ship: A New Direction For Managing Wood Waste In The Salish Sea Of Washington State, Russ Mcmillan, Chance Asher, John Evered, Celina Abercrombie
Turning The Ship: A New Direction For Managing Wood Waste In The Salish Sea Of Washington State, Russ Mcmillan, Chance Asher, John Evered, Celina Abercrombie
Salish Sea Ecosystem Conference
Wood waste has been a major driver in numerous large scale, nearshore cleanups in Washington State Its presence has contributed substantially to both the extent and volume of sediment requiring cleanup which is costly and time consuming. Success in dealing with wood waste must start with controlling sources and a reassessment of how timber-related uses of our waters are conducted. Recognizing its ecological impacts and the financial burden of cleanup prompts the change from practices that release wood waste to state waters. While it is tough to change from traditional use of waters for transport and storage of logs or …

Reconstructing Historical Patterns Of Primary Production In Puget Sound Using Growth Increment Data From Shells Of Long-Lived Geoducks (Panopea Generosa), Jenny Eccles, Correigh M. Greene, Kathryn Sobocinski, Bethany Stevik, Henry Carson, Christopher Krembs
Salish Sea Ecosystem Conference
Bottom-up hypotheses predict that changes in primary production affect marine survival of species like Pacific salmon. Long term records of primary production would provide important data to test these predictions. However, direct observations of primary production (in situ fluorometers, water chemistry, and satellite observations of color back-scatter) have relatively short time series (< 30 years). We investigated whether growth increments of geoduck clams (Panopea generosa) are correlated with primary production in different sub-basins of greater Puget Sound. Geoduck are long-lived (older specimens live >100 years), widely distributed throughout the Salish Sea, and deposit annual growth rings in their shells. Shell samples from aged geoducks were by the Washington Department of Fish and Wildlife in four sub-basins within greater Puget Sound (Strait of Jan de Fuca, Southern Strait of Georgia, South …
What Climate Change Means For The Salish Sea, Nathan Vadeboncoeur
What Climate Change Means For The Salish Sea, Nathan Vadeboncoeur
Salish Sea Ecosystem Conference
The Salish Sea is a hub of interconnectivity. It is a key link for international trade between North America and Asia, home to approximately 11.5 million people and two large cosmopolitan urban centres, and connects climates regimes ranging from temperate rainforest to cool Mediterranean. The Salish Sea is also a nexus for political and ecological frontiers. It is divided by the Canada-USA border and is an ecological transition zone connecting the Alaskan and Californian Current ecosystems. Climate change will affect this region via its influence on watersheds, coastal microclimates, and marine ecosystems. These effects can have potentially serious consequences for …

Contaminants Of Emerging Concern In Bay Mussels Throughout The Salish Sea, Christopher Andrew James, James E. West, Sandra M. O'Neill, Jennifer Lanksbury
Salish Sea Ecosystem Conference
Monitoring of bay mussels (Mytilus trossulus) has been an important part of WDFW’s Toxics-focused Biological Observation System (TBiOS) in the Puget Sound. Traditional monitoring has focused on a suite of priority compounds including PAHs, PCBs, PBDEs, and metals. In order to expand the range of compounds investigated, we undertook a pilot program in 2016 to analyze a select set of tissue samples for contaminants of emerging concern (CECs), utilizing two distinct analytical approaches. One set was analyzed by targeted methods focusing on a suite of over 200 pharmaceuticals, personal care products, and endocrine disrupting compounds. The results supported the notion …
Zooplankton Variability In The Northern Salish Sea Over The Past 3 Decades, And Relationships With Coho Salmon, Kelly Young, Moira Galbraith, Richard Ian Perry
Zooplankton Variability In The Northern Salish Sea Over The Past 3 Decades, And Relationships With Coho Salmon, Kelly Young, Moira Galbraith, Richard Ian Perry
Salish Sea Ecosystem Conference
The past 30 years have seen huge changes in the populations of Pacific salmon in the Salish Sea. These changes include very large reductions in the abundances of Chinook and Coho, and high variability of Fraser River Sockeye salmon populations. The Salish Sea Marine Survival Program is a Canada – U.S. collaborative multi-year research initiative established to investigate two main questions: what has driven the very strong declines in abundances of Coho and Chinook populations in the Salish Sea since the 1980s, and what determines the interannual variability of present populations. In this study we examine these two questions from …

Telemetry Tracking Of Salmon Smolt Migrations Through The Salish Sea: Examining Behaviour, Survival And Causes Of Mortality, Scott Hinch, Nathan Furey, Christine Stevenson, Steve Johnstone, Steve Healy, David Welch, Erin Rechisky, Aswea Porter, Kristi Miller
Salish Sea Ecosystem Conference
The Salish Sea is an important migratory corridor and feeding area for juvenile salmonids yet little is known regarding movement behaviours and survival through this region. We used acoustic telemetry tracking in sockeye and steelhead smolts to: 1) identify marine travel rates and routes, 2) estimate migration survival rates, and 3) identify factors contributing to mortality. Sockeye smolts travelled at 10 km / day in their clear natal river, 200 km / day in the turbid Fraser River mainstem, and 10-15 km / day in the marine environment. Steelhead smolts travelled approximately 2-3 times faster in the same marine segments, …
Key Factors Influencing Change In Pacific Herring Populations: A Qualitative Network Model Approach, Tessa B. Francis
Key Factors Influencing Change In Pacific Herring Populations: A Qualitative Network Model Approach, Tessa B. Francis
Salish Sea Ecosystem Conference
Pacific herring are a foundational species in the Salish Sea, providing important cultural, social, economic, and ecological benefits throughout the ecosystem. While herring are common across the Salish Sea, patterns of their abundance in recent years vary spatially. Herring are subject to many factors that may influence their abundance and distribution, but there is no agreement on what the key factors are or, therefore, how to address local declines and support herring resilience. Here, we present results from a qualitative network model of the herring ecological system evaluating the relative support for the influence of different possible factors on herring …

Salish Sea Ecosystem Conference
While ocean acidification was first investigated as a global phenomenon, coastal acidification has received significant attention in recent years, as its impacts have been felt by different socio-economic sectors (e.g., high mortality of shellfish larvae in aquaculture farms). As a region that connects land and ocean, the Salish Sea (consisting of Puget Sound and the Straits of Juan de Fuca and Georgia) receives inputs from many different sources (rivers, wastewater treatment plants, industrial waste treatment facilities, etc.), making these coastal waters vulnerable to acidification. Moreover, the lowering of pH in the Northeast Pacific Ocean also affects the Salish Sea, as …

A Modeling Study Of Storm Surge In The Salish Sea, Zhaoqing Yang, Taiping Wang, Ian Miller
Salish Sea Ecosystem Conference
The Pacific Northwest coasts are subject to the threat of coastal inundation as a result of storm surge. This snapshot presentation provides an overview of a modeling study of storm surge in the Salish Sea using a high resolution coastal hydrodynamic model. A series of historical storm surge events were identified based on non-tidal residual (NTR) water levels observed at Seattle tide gage. Model simulations corresponding to selected storm surge events were conducted. The Salish Sea storm surge model was validated with both observed tidal and NTR data at NOAA tide gauges in the Salish Sea. Sensitivity analysis on the …
If Historic Marine Pollution Ceases, Will The Natural Intertidal Community Return? How Exposure To And Release From Pollution Disturbance Shapes Rocky Intertidal Communities In The Salish Sea, Shannon Bard, Aaron Eger, Julia Baum
If Historic Marine Pollution Ceases, Will The Natural Intertidal Community Return? How Exposure To And Release From Pollution Disturbance Shapes Rocky Intertidal Communities In The Salish Sea, Shannon Bard, Aaron Eger, Julia Baum
Salish Sea Ecosystem Conference
Marine ecosystems in the Salish Sea are subject to a variety of pollution-based disturbances that restructure the composition of the vegetative and animal communities. A prime historical example of this is the effluent discharged from pulp mills across the province, which have been shown to have substantial negative impacts on coastal biodiversity. However, as environmental regulations have become more stringently enforced and the economic drivers of pulp mills have slowed down, in some areas much of this pollution has abated. The diminishment and in some cases, elimination of such disturbances provides a unique opportunity to assess the recovery of communities …

Managing Disposal At Sea In The Salish Sea To Protect Southern Resident Killer Whale Habitat, Rebecca Seifert, Adam La Rusic
Salish Sea Ecosystem Conference
The Southern Resident Killer Whale (SRKW) population is listed as Endangered under Canada’s Species at Risk Act. As part of its Ocean Protection Plan, Canada is taking action to protect SRKW and their defined Critical Habitat in the Salish Sea. Identified threats to SRKW include noise from vessels, availability of prey, and contaminants. Through the Canadian Environmental Protection Act (CEPA), Environment and Climate Change Canada (ECCC) assesses and permits the disposal of waste at sea, including disposal at a designated site in SRKW habitat. As well, ECCC conducts regular, required monitoring at disposal sites. The monitoring program holds several years …
