Lessons From Long Time-Series Of Benthic Invertebrate Communities In The Southern Salish Sea, And An Expansion Of Parameters To Assess Nutrient Loading And Climate Change Pressures, Valerie Partridge, Margaret Dutch, Sandra Weakland, Dany Burgess, Angela Eagleston

Salish Sea Ecosystem Conference

Changes in habitat and benthic invertebrates indicate responses of the ecosystem to stressors. Since 1989, the Washington State Department of Ecology has monitored sediments and benthic invertebrate communities annually at ten sentinel stations. This is a unique and important dataset, providing yearly insights into benthic community structure and abundance cycles of individual species. Except where events destabilized the habitats and communities, the sediments at these ten long-term stations, and the invertebrate communities inhabiting them, have largely remained stable over time, though with some drift and cycles in species composition and abundance. A few of these long-term stations, however, have experienced …

Did The Rules Work? An Assessment On The Effectiveness Of Federal Vessel Regulations For Southern Resident Killer Whales, Teresa Mongillo, Grace Ferrara, Lynne Barre

Salish Sea Ecosystem Conference

Southern Resident killer whales (Orcinus orca) in the Pacific Northwest are the principal target species for a commercial whale watch industry and encounter a variety of other vessels in their urban environment. The population was listed as endangered in 2005 due to limited prey, high levels of contaminants, and disturbance from vessels and sound. There has been a growing body of evidence documenting effects from vessels on small cetaceans and other marine mammals including behavioral disturbance, physiological impacts, and acoustic interference. The National Marine Fisheries Service (NMFS) Recovery Plan identified actions to address vessel impacts, including vessel regulations. In 2011, …

Recent Progress Toward Reducing Seawalls In Puget Sound, Doris J. Small, Hugh Shipman, Jenna Jewett, Nathalie Hamel

Salish Sea Ecosystem Conference

Recovery efforts for Puget Sound have focused on improving shoreline function by reducing seawalls (e.g. rock and concrete bank protection) and encouraging alternatives, such as soft shore protection. Shoreline armor was one of the key stressors identified by the Puget Sound Partnership in 2010 to protect and restore habitat. Armor is one of the Puget Sound Vital Signs, those measures used by the Puget Sound Partnership to track ecosystem health. One of the targets associated with the Vital Sign, a net reduction of the total extent of armor between 2011 and 2020, is tracked using the Hydraulic Project Approval (HPA) …

Application Of Genomics To Develop A Monitoring Tool For Stormwater Treatment Wetlands, Jessica Lenoble, Chris Johnston, James Atwater, Susan Baldwin Apr 2018

Application Of Genomics To Develop A Monitoring Tool For Stormwater Treatment Wetlands, Jessica Lenoble, Chris Johnston, James Atwater, Susan Baldwin

Salish Sea Ecosystem Conference

Urban stormwater treatment wetlands benefit communities because they filter pollutants from receiving waters and provide habitat for urban wildlife and birds. The installation of wetlands is often avoided because stormwater quality is highly variable, which makes it both challenging and expensive to ensure that the wetlands are effectively mitigating the impacts of stormwater runoff. For decades, macroscopic species, such as benthic invertebrates, have been used as biological indicators of watershed health. With recent advancements in genomics (the branch of science that studies the function and structure of DNA within a single cell), it may now be feasible to use microscopic …

Characterizing Underwater Radiated Noise From Pacific Whale Watch Association Vessels, David Hannay, Brett Soberg Apr 2018

Characterizing Underwater Radiated Noise From Pacific Whale Watch Association Vessels, David Hannay, Brett Soberg

Salish Sea Ecosystem Conference

The commercial whale watch industry is interested in understanding the nature of underwater noise produced by whale watch vessels, to help their operators minimize noise emissions. Most focus on vessel-related noise has been on large commercial shipping vessels, with very little attention paid to the smaller vessel types used for commercial whale watching and for recreational purposes. Whale watch companies need this information to guide choices of equipment, such as propulsion systems, to minimize noise emissions that lead to exposures of the marine fauna that are the focus of their industry. In summer 2017, several Pacific Whale Watch Association (PWWA) …

Salish Sea Bull Kelp Restoration Research: Local, Regional And International Collaborations, William Heath, Sherryl Bisgrove

Salish Sea Ecosystem Conference

Bull kelp forests are important nearshore habitats for many fish and invertebrates and are an integral part of the “salmon highway” from river to estuary to ocean and back. In recent decades kelp forests have been in serious decline in the Salish Sea and other coastal regions. Research to improve our understanding of causes of the decline and on restoration methods began in the north Salish Sea in 2011 with a kelp out-planting project by Nile Creek Enhancement Society(NCES) at Hornby Island. NCES and Project Watershed began a collaboration in 2015 with work in the K'omoks Estuary and Cape Lazo …

Bringing High Resolution Land Cover Products To The Puget Sound Region And U.S., Melissa Rosa

Salish Sea Ecosystem Conference

Understanding land cover patterns and their changes is essential to comprehensive natural resource management and conservation planning. Land cover products derived from satellite imagery and other remotely sensed data can provide information for resource inventories and assessments, track progress of management plans, and monitor impacts of ecosystem change at the landscape scale. For almost two decades, NOAA’s Office for Coastal Management has been using satellite imagery to produce standardized, regional land cover and change information for the coastal U.S. through its Coastal Change Analysis Program (C-CAP). C-CAP products are updated every five years and provide additional wetland categories for nearshore …

Declines In Puget Sound Sediment-Dwelling Communities And A New Focus On Climate, Nutrient, And Other Ecosystem Stressors, Sandra Weakland, Valerie Partridge, Margaret Dutch, Dany Burgess, Angela Eagleston

Salish Sea Ecosystem Conference

The Washington State Department of Ecology has been collecting data on Puget Sound sediment-dwelling (benthic) invertebrates since 1989, as part of the Marine Sediment Monitoring Program. Benthic organisms serve key functions, including processing and storage of organic material and cycling of nutrients needed by other components of the ecosystem. Benthic invertebrates are an integral part of the marine food web and biogeochemical processes that support salmon, orcas, and humans and are a key component of the Puget Sound ecosystem. We are finding significant declines in the overall condition of benthic communities, with 44% of the study area adversely affected. Many …

Using Surface Elevation Tables And Marker Horizons To Evaluate Resiliency And Trajectories Of Tidal Marshes And Restoration Projects In The Snohomish River Estuary, Devin Robinson, Jason Hall, Joshua Chamberlin, Todd Zachery, Casimir Rice Apr 2018

Using Surface Elevation Tables And Marker Horizons To Evaluate Resiliency And Trajectories Of Tidal Marshes And Restoration Projects In The Snohomish River Estuary, Devin Robinson, Jason Hall, Joshua Chamberlin, Todd Zachery, Casimir Rice

Salish Sea Ecosystem Conference

The abundance of tidal wetlands has been increasingly impacted by environmental changes, human alterations and sea-level rise around the world. Elevation and sediment dynamics control tidal wetland vegetation colonization, assemblages, resiliency, and recovery trajectories. Seal level rise and hydromodifications may threaten the resiliency of existing tidal marshes, and impact the recovery trajectories of restoration projects. The Snohomish river delta currently supports the second largest extent of tidal wetlands in the Puget Sound, and has become the focus of what could be the largest cumulative estuary restoration effort in Puget Sound. However, we currently know very little about elevation and sediment …

The Pacific Salmon Explorer: A Data Driven Look At Salmon Populations And Their Habitats, Katrina Connors, Eileen Jones, Leah Honka, Katy Kellock, Eric Hertz, Brian E. Riddell

Salish Sea Ecosystem Conference

The lack of a centralized, standardized, and easily accessible repository of information on the state of natural resources, and threats to them, can undermine efforts to make informed, transparent, and evidenced-based management and conservation decisions. This is the case with Pacific salmon in British Columbia (BC), where a lack of information on the current status of salmon population and their habitats is undermining public confidence in the ability of government agencies to sustainability manage Pacific salmon populations. In an effort to provide broader public access to salmon datasets, the Pacific Salmon Foundation embarked on a major initiative to synthesize the …

Quantifying Marine Vessel Traffic From Aerial Surveys In The Salish Sea, Norma Serra-Sogas, Patrick O'Hara, Rosaline Canessa, Lauren Mcwhinnie Apr 2018

Quantifying Marine Vessel Traffic From Aerial Surveys In The Salish Sea, Norma Serra-Sogas, Patrick O'Hara, Rosaline Canessa, Lauren Mcwhinnie

Salish Sea Ecosystem Conference

There are a number of potential impacts associated with vessel traffic on marine ecosystems, including noise and oil pollution, ship-strikes, and fishing and fisheries bycatch. To assess these impacts, many studies employ marine traffic data collected using Automatic Identification Systems (AIS) onboard vessels. However, AIS only captures a fraction of the actual marine traffic because it omits many of the smaller vessels, which are not legally required to carry AIS. Without this information, the assessment of vessel-associated impacts based on AIS is inherently flawed, and underestimated. The NEMES (Noise Exposure to the Marine Environment from Ships) project is particularly interested …

Effects Of Warm Ocean Temperatures On Bull Kelp Forests In The Salish Sea, Braeden Schiltroth, Sherryl Bisgrove, Bill Heath

Salish Sea Ecosystem Conference

Kelp beds are marine sanctuaries, providing some of the most productive ecosystems on the planet and serving as critical habitat and refuge for many species, including juvenile salmon. Rising ocean temperature associated with climate change is a major stressor contributing to declines of kelp forests worldwide. In the Salish Sea, we identified bull kelp (Nereocystis leutkeana) populations growing under two different temperature regimes. Since 2011, kelp growing in the central Strait of Georgia has been exposed to sea surface temperatures (SSTs) of 15-21 °C in the summer months, which is 5-6 °C warmer than temperatures in the Strait of Juan …

Research Into The Cause Of Brackish Marsh Recession In The Fraser River Estuary, Brent Gurd, Sean Boyd, Eric Balke, Richard Marijnissen, Brad Mason, Kathleen Moore Apr 2018

Research Into The Cause Of Brackish Marsh Recession In The Fraser River Estuary, Brent Gurd, Sean Boyd, Eric Balke, Richard Marijnissen, Brad Mason, Kathleen Moore

Salish Sea Ecosystem Conference

At least 160 ha (30%) of the brackish marsh on Sturgeon Bank in the Fraser River estuary have disappeared since 1989. A collaborative effort between the provincial and federal governments and industry aims to determine the cause(s) of the recession to inform future restoration efforts. Three adjacent low-elevation brackish marshes along the delta front have also receded to varying degrees. River training structures and regular dredging of the Fraser River divert sediments and fresh water, and thus alter sediment and salinity patterns along the delta front. Lesser snow geese (Anser c. caerulescens) preferentially grub bulrush, and the Fraser-Skagit population has …

Genetic Structure Of The Bull-Kelp Nereocystis Luetkeana In The Salish Sea, Lily Gierke, Bobby San Miguel, Tom Mumford, Filipe Alberto

Salish Sea Ecosystem Conference

Despite its vast geographic range and important role in coastal ecosystems in the Pacific Northwest, the bull kelp, Nereocystis luetkeana, has historically not been as widely studied as its globally distributed sister kelp, Macrocystis pyrifera. To date, there have been no published studies on the population genetic structure of Nereocystis luetkeana. We developed 10 polymorphic microsatellite markers with 454 sequencing and used them to genotype a total of over 1000 samples distributed from over 32 sites within the Salish Sea. Anthropogenic impact in the Salish Sea has been associated with decreasing kelp cover in areas close to large urban centers. …

The 2011 Climate Regime Shift: Seabed Taxon Monitoring Identifies Regimes, Jeff Marliave, Donna Gibbs, Laura Borden

Salish Sea Ecosystem Conference

Monitoring of biodiversity may sometimes reflect human impacts on ecosystems, but analysis of biodiversity needs to account for naturally occurring trends as well. Biodiversity may provide more accurate definition of climate regime shifts than do physical oceanographic data, Using search programs for a long-term SCUBA taxonomic database (3865 dives) for Strait of Georgia seabed sites, 1,077 taxa were screened to select 171 rare or highly abundant taxa and to present the data according to climate regime categories. Ocean Niño Index climate regime shifts are defined here as the year of the end of the first La Niña closely paired with …
