Evaluating Common Trends In Chinook Density And The Influence Of Temperature And Salinity Patterns Among Distributary Channels In A Large River Estuary To Aid Evaluation, Planning, And Prioritization Of Restoration Activities, Joshua Chamberlin, Jason E. Hall, Todd Zackey, Frank Leonetti, Michael Rustay

Salish Sea Ecosystem Conference

Landscape context is critical in estuary restoration planning and assessment due to the complexity and size of estuaries, and the unique attributes and cumulative effects of individual restoration projects. In addition, the diversity and mobility of estuarine species, in particular juvenile salmon, highlights the importance of landscape position given certain locations in the delta are less accessible to salmon. The Snohomish River delta has been the focus of major estuary restoration efforts in recent years and efforts could result in the largest cumulative estuary restoration action in Puget Sound. While several large projects have been initiated/competed in recent years, information …

Influence Of Sedimentary Biogeochemistry On Oxygen Consumption And Nutrient Cycling In Bellingham Bay, Washington, Everitt G. Merritt, David Shull Apr 2018

Influence Of Sedimentary Biogeochemistry On Oxygen Consumption And Nutrient Cycling In Bellingham Bay, Washington, Everitt G. Merritt, David Shull

Salish Sea Ecosystem Conference

Bellingham Bay, a shallow, urbanized embayment in north Puget Sound, is experiencing increasing seasonal hypoxia. But, rates of sedimentary geochemical processes that might contribute to this change are not well quantified. This project explored the relationships between sedimentary biogeochemical processes, nutrient fluxes, and oxygen consumption in Bellingham Bay. Working with the Washington State Department of Ecology, we sampled 25 stations throughout the bay, and measured fluxes of dissolved oxygen, dissolved inorganic nitrogen, dissolved inorganic phosphorus, silicate, and dissolved inorganic carbon between sediment and overlying water. We observed decreases in the fluxes of DO, DIC, and DIN with station depth, suggesting …

Commercial Ship Versus Whale Watch Boat Noise: Relative Effects On Southern Resident Killer Whales, Jason Wood, Dominic Tollit, Ruth Joy, Nicole Koshure, Alex Macgilivray, Krista Trounce, Orla Robinson Apr 2018

Commercial Ship Versus Whale Watch Boat Noise: Relative Effects On Southern Resident Killer Whales, Jason Wood, Dominic Tollit, Ruth Joy, Nicole Koshure, Alex Macgilivray, Krista Trounce, Orla Robinson

Salish Sea Ecosystem Conference

Underwater noise may be impacting the population recovery of critically endangered Southern Resident Killer Whales (SRKW). This study used an SRKW-Noise exposure simulation model to compare noise effects from large (AIS-enabled) commercial vessels with whale watch boats during summer (May-September) within their principal Salish Sea habitat range use. It predicted moderate or low behavioural responses (BRs) using SRKW-specific dose-response relationships and, if no BRs were triggered, the extent of residual high frequency echolocation click masking. BRs were considered to result in lost foraging due to switches in behaviour or via strong masking effects. The Monte-Carlo simulation used a fine-scale acoustic …

Small City Meets Big Water Quality Improvement Challenges, Mark Henderson, Andrea Hood Apr 2018

Small City Meets Big Water Quality Improvement Challenges, Mark Henderson, Andrea Hood

Salish Sea Ecosystem Conference

From 1980 to 2011, the City of Blaine’s wastewater treatment plant (WWTP) was located on Semiahmoo Spit, a peninsula west of the city, across the mouth of Drayton Harbor. During those years, raw sewage from Blaine traveled in a pipe across the waters of Drayton Harbor for treatment. Pollution challenges included leaks in the transfer pipe and a failing collection system that allowed inflow and infiltration to overwhelm the system during rain events. The WWTP reached its capacity in the late 1990s. WWTP upgrade construction began in 1999 at the Semiahmoo Spit site. Contractor mismanagement of Native American human remains …

Transboundary Cooperation To Reduce Bacterial Pollution In Washington's Lower Nooksack Basin, Doug Allen, Steve Hood Apr 2018

Transboundary Cooperation To Reduce Bacterial Pollution In Washington's Lower Nooksack Basin, Doug Allen, Steve Hood

Salish Sea Ecosystem Conference

The presence of fecal coliform bacteria in streams and shallow marine waters used to grow and harvest shellfish indicate the presence of human- and animal-borne pathogens that can cause serious illness. People who contact polluted water or eat shellfish contaminated with these pathogens are at risk. Since 1998, state and local agencies, dairy operators, farmers, septic system owners and others have worked to address this concern. In 2012, a partnership of local, state and federal entities started the Whatcom Clean Water Program (WCWP), with the purpose of reducing fecal coliform contamination in Drayton Harbor and Portage Bay. County and State …

Engaging The Community In Drayton Harbor's Comeback Story, Betsy Peabody Apr 2018

Engaging The Community In Drayton Harbor's Comeback Story, Betsy Peabody

Salish Sea Ecosystem Conference

During the 1980 and 1990s, bacterial contamination in Drayton Harbor resulted in bay-wide closures of tribal, commercial and recreational shellfish harvest. In 2001, Puget Sound Restoration Fund partnered with local shellfish farmer extraordinaire Geoff Menzies to launch the Drayton Harbor Community Oyster Farm. With Geoff at the helm, the community farm invigorated a 20+ year community-wide effort to restore 810 acres of growing area to Approved harvest status in 2016. At the outset, seeding oysters in a bay prohibited to harvest, and involving volunteers in oyster farming, was a gamble. But the vision was that if people became immersed in …

What Climate Change Means For The Salish Sea, Nathan Vadeboncoeur Apr 2018

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 …

Stable Isotope Analysis Reveals Different Trophic Niche Spaces For Wild And Hatchery Origin Juvenile Chinook Salmon In The Nisqually Delta, Melanie Davis, Isa Woo, Christopher S. Ellings, Sayre Hodgson, Susan De La Cruz Apr 2018

Stable Isotope Analysis Reveals Different Trophic Niche Spaces For Wild And Hatchery Origin Juvenile Chinook Salmon In The Nisqually Delta, Melanie Davis, Isa Woo, Christopher S. Ellings, Sayre Hodgson, Susan De La Cruz

Salish Sea Ecosystem Conference

Hatchery programs have been used as a conservation tool to bolster declining Chinook salmon (Oncorhynchus tshawytscha) populations throughout much of the Salish Sea. In many watersheds, hatchery fish are released concurrently with the natural-origin population, thus raising the potential for density dependent effects via depleted prey resources, territorial behavior, and movement into sub-optimal habitats. Competition during the critical period for early marine growth and survival might have detrimental effects for wild Chinook salmon populations, highlighting the potential importance of a productive delta habitat mosaic. We used an integrated diet approach with stomach content and stable isotope analyses to evaluate differential …

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 Apr 2018

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 …

Capturing Information On Vessels And Cetaceans: Developing A Passive Monitoring System For Boundary Pass, Lauren Mcwhinnie, Patrick O'Hara, Gregory O'Hagan, Molly Fraser, Sarah Berry, Leh Smallshaw, Norma Serra-Sogas, Rosaline Canessa

Salish Sea Ecosystem Conference

As marine traffic intensifies in the Salish Sea, cetaceans, and in particular, Southern Resident Killer Whales (SRKWs), are continually facing increasing amounts of exposure to noise and other disturbances from movements of vessels. While the majority of large vessel activity can be captured and assessed through the use of Automatic Identification Systems (AIS), the contribution of smaller non-AIS vessels is difficult to quantify and currently largely under assessed. Increasingly, government and industry are required to take operational and strategic mitigation measures to minimise vessel disturbances on cetaceans without reliable, comprehensive data and analysis to inform those decisions. Therefore this work …

Density-Dependent And Landscape Effects Upon Estuary Rearing In Chinook Salmon: Insights From Long-Term Monitoring In Four Puget Sound Estuaries, Correigh M. Greene, Eric M. Beamer, Rich Henderson, Joshua Chamberlin, Jason Hall, Joseph H. Anderson, Matthew Pouley, Melanie Davis, Sayre Hodgson, Christopher Ellings

Salish Sea Ecosystem Conference

Juvenile Chinook salmon are well known for utilizing estuarine habitats within the tidal delta for rearing during outmigration. Several studies have linked population responses to availability of estuary habitat, and support the hypothesis that estuarine habitats are vital rearing areas for juvenile Chinook salmon. However, these coarse-scale studies provide little insight on how specific estuarine habitats contribute to rearing potential for salmon. We integrate long-term monitoring data from four estuaries of Puget Sound (Nooksack, Skagit, Snohomish, and Nisqually) to examine whether 1) Chinook populations in these rivers are limited by restricted estuary habitat, 2) hatchery releases can influence density dependent …

Fine-Scale Taxonomic And Spatiotemporal Variability In The Energy Density Of Prey For Juvenile Chinook Salmon (Oncorhynchus Tshawytscha), Jacob Weil, Will Duguid, Francis Juanes Apr 2018

Fine-Scale Taxonomic And Spatiotemporal Variability In The Energy Density Of Prey For Juvenile Chinook Salmon (Oncorhynchus Tshawytscha), Jacob Weil, Will Duguid, Francis Juanes

Salish Sea Ecosystem Conference

The growth and survival of juvenile Chinook salmon (Oncorhynchus tshawytscha) are determined in part by biotic and abiotic conditions experienced during their first marine summer. Of the biotic conditions, the quality of available prey is integral for optimal growth and survival. Current studies that investigate the effect of variable prey quality on salmon growth approximate energy density using literature values. This approach ignores fine-scale taxonomic as well as spatial and temporal differences in prey quality. To address these possible sources of error, monthly zooplankton tows were performed in Saanich Inlet, Cowichan Bay and Maple Bay off the coast of Vancouver …

Blue Carbon: Port Of Seattle’S Kelp, Eelgrass And Shellfish Enhancement Pilot Project, Jon Sloan Apr 2018

Blue Carbon: Port Of Seattle’S Kelp, Eelgrass And Shellfish Enhancement Pilot Project, Jon Sloan

Salish Sea Ecosystem Conference

The Port of Seattle is working to become carbon neutral by 2050. In addition to reducing emissions, the Port’s strategy includes enhancing carbon sequestration through habitat restoration. To that end, the Port completed a study in 2017 to quantify sequestration benefits associated with different land cover and habitat types found in the Duwamish River estuary and Elliott Bay, including riparian forest, marsh, mudflat, eelgrass and kelp beds. The review determined that kelp and eelgrass – so called “blue carbon” – provide highly significant sequestration benefits. In fact, they sequester more carbon than almost any other habitat type in the world. …

Salmon And Jellies And Herring, Oh My! Abiotic And Biotic-Dependent Trends In Abundance And Distribution Of Pelagic Critters In Skagit Bay Across 17 Years, Stuart Harold Munsch, Correigh M. Greene, Jason Hall

Salish Sea Ecosystem Conference

As a large fjord, the Salish Sea exhibits strong spatiotemporal variation in temperature and salinity due to various marine and freshwater inputs. These patterns are particularly evident in Skagit Bay where water conditions are influenced by marine inputs from Deception Pass and Saratoga Passage and seasonal pulses of fresh water from Skagit River. We investigated how abundance and community composition in pelagic surface waters of Skagit Bay varied from 2001-2017, and how temperature and salinity patterns can influence which species predominate in particular years. Data come from long-term monitoring of Skagit Bay using a Kodiak surface trawl that sweeps the …

Microplastics Contamination In Blue Mussels (Mytilus Edulis (L.)) And Marine Sediments Along The Coast Of British Columbia, Canada, Megane Neauport, Marie Noel, Anahita Etemadifar, Peter Ross Apr 2018

Microplastics Contamination In Blue Mussels (Mytilus Edulis (L.)) And Marine Sediments Along The Coast Of British Columbia, Canada, Megane Neauport, Marie Noel, Anahita Etemadifar, Peter Ross

Salish Sea Ecosystem Conference

Contamination of marine ecosystems with microplastics (plastic particles ≤ 5mm) is now recognized as a serious and growing threat to sealife. One major concern is that invertebrates, fish, seabirds and marine mammals mistake plastic for food, leading to suffocation, blockage of the gut and/or malnutrition. Microplastics have been detected in sediment around the world, highlighting the propensity of this matrix to serve as a sink. Due to their extensive filter-feeding activity, marine bivalves are directly exposed to this structural pollutant. In the present study, we investigate microplastics contamination in nearshore subtidal sediment and mussel samples collected at 43 sites along …
