Mapping Whale-Watching Effort Using Ais Data In The Salish Sea, Norma Serra-Sogas Apr 2022

Mapping Whale-Watching Effort Using Ais Data In The Salish Sea, Norma Serra-Sogas

Salish Sea Ecosystem Conference

Commercial boat-based whale-watching is a very important touristic sector in the Salish Sea, taking thousands of people to view and experience up close the natural beauty and wildlife of the area. This sector provides economic benefits to local communities and opportunities for education and increase awareness for nature protection. The recent growth of whale-watching activities also can bring potential negative effects such as disturbances to wildlife. To achieve a sustainable commercial whale-watching sector, it is important to gain a good understanding of the footprint this activity has on the marine environment. For this, we assessed the spatio-temporal distribution of whale …

Foraging Strategy, Prey Preferences And Limited Competition Among Forage Fishes In The San Juan Islands; Implications For Chinook Recovery, Russel Barsh Apr 2022

Foraging Strategy, Prey Preferences And Limited Competition Among Forage Fishes In The San Juan Islands; Implications For Chinook Recovery, Russel Barsh

Salish Sea Ecosystem Conference

Previous research has shown that juvenile Chinook outmigrants prey preferentially on young-of-year Pacific herring and Pacific sand lance as they transit the San Juan Islands. The relative abundance of these two forage fishes and their proportional representation in the neritic diet of juvenile Chinook have varied since 2009 in ways that suggest that they respond to changing marine conditions in different ways, including relying seasonally on different zooplankton prey. In 2020 and 2021, co-occurring forage fishes (herring, sand lance, Pacific surf smelt, Northern Anchovy) and zooplankton were collected from a Lopez Island bay where juvenile Puget Sound Chinook annually congregate. …

Holistic Approaches For Invasive Species Management: Exploring Biotic Resistance Of European Green Crab (Carcinus Maenas) Via River Otter (Lontra Canadensis) Diet, Bobbie Buzzell

Salish Sea Ecosystem Conference

Establishment of the European green crab (Carcinus maenas) on the west coast United States has led to concerns regarding loss of eelgrass beds and influence on marine communities. To begin examining whether predators can potentially buffer green crab expansion, I studied river otter (Lontra canadensis) diet from scat remains and green crab abundance was estimated from removal trapping efforts. River otter scats on the Wa’atch and Tsoo-Yess rivers, Washington, USA, were collected during August-September 2018 and April-September 2019. Hard remains of prey were reported as percent frequency of occurrence, and green crab prey were compared to monthly catch-per-unit-effort (CPUE). Scats …

Seasonal Changes In Trophic Interactions In The Plankton Community In The Strait Of Georgia, Nicole Mcewan Apr 2022

Seasonal Changes In Trophic Interactions In The Plankton Community In The Strait Of Georgia, Nicole Mcewan

Salish Sea Ecosystem Conference

As the base of the food web, plankton are key in energy transfer and influence the biomass and composition of organisms higher up in the food web. However, the diversity of plankton species, as well as their trophic processes and interactions are often over-simplified in food web models. Throughout a year, the plankton community varies greatly, further increasing the complexity of trophic flows. Here, we have used Ecopath to model the plankton food web in the Strait of Georgia in three seasons. The plankton community is represented in the models by ten mesozooplankton groups, two mixotrophic microzooplankton groups, one phytoplankton …

Species Abundance And Conditions Of Plankton Blooms In Possession Sound, Maci Larsen Apr 2022

Species Abundance And Conditions Of Plankton Blooms In Possession Sound, Maci Larsen

Salish Sea Ecosystem Conference

Harmful algal blooms (HABs) can threaten the health and stability of an ecosystem. They occur when there is a significant increase in the abundance of toxin-producing phytoplankton. Paralytic shellfish toxins are just one example of how these massive blooms can be lethal to marine life and even humans if the poisoned shellfish are consumed. HABs are seen as a considerable threat to the ecosystem, but what about the non-HAB-forming plankton that make the waters of the Salish Sea their home? Plankton of many kinds do not require complex conditions for blooming to occur; it can be as simple as temperature …

Does Ocean Acidification Affect The Bioenergetics And Susceptibility To Pathogenic Disease In Juvenile Pacific Herring (Clupea Pallasii)?, Christopher Murray

Salish Sea Ecosystem Conference

This study examined how chronic exposure to ocean acidification affects the bioenergetics and immune functionality of juvenile Pacific herring (Clupea pallasii). Wild herring offspring were reared from hatch under three contrasting pCO2 treatments [low (~650 µatm), intermediate (~1,500 µatm), and high (~3,000 µatm)] to assess impacts on long-term growth, critical swim speed (Ucrit), and susceptibility to the viral hemorrhagic septicemia virus (VHSV). During the first two months of larval development, growth trajectories were largely unaffected by pCO2 level. However, between 60 - 105 days post-hatch (dph), treatment mean growth rates (±SD) were significantly reduced under high (0.59±0.09 mm·d-1) and intermediate …

Nitrogen In The Nooksack River Watershed: Comparing Models To Monitoring, David U. Hooper Apr 2022

Nitrogen In The Nooksack River Watershed: Comparing Models To Monitoring, David U. Hooper

Salish Sea Ecosystem Conference

The Nooksack River Watershed of northwest Washington and southwest British Columbia faces several issues linked to high nitrogen (N) in surface and groundwater. The Sumas-Blaine Aquifer, a locally important drinking water source, has nitrate levels that exceed the EPA recommended 10 mg nitrate-N/L in many wells. Many tributaries to the Nooksack River have 303(d) listings as “impaired” for dissolved oxygen, which is tied to high nutrient loading. Based on results from the USGS Sparrow model, the Nooksack River has one of the highest rates of N loading per watershed area to the Salish Sea of all monitored rivers, contributing to …

Projected Changes To The Hydroclimate In The Pacific Northwest And Implications For Coastal Hazards And Compound Flooding, Nathan Vanarendonk Apr 2022

Projected Changes To The Hydroclimate In The Pacific Northwest And Implications For Coastal Hazards And Compound Flooding, Nathan Vanarendonk

Salish Sea Ecosystem Conference

Future changes in the Pacific Northwest climate have implications for regional habitat restoration, flood hazard mitigation and community resilience. Modeling regional exposure to flooding requires capturing the interactions of extreme stream discharge, sea levels, and flood mitigation controls (e.g., dams, flood gates). Here, extreme statistics of stream flow are derived from ensemble hydroclimate forecasts throughout Puget Sound, provided by the Columbia River Climate Change study (CRCC, Chegwidden et al., 2017). Flow projections are examined from four hydrologic models (three Variable Infiltration Capacity models and one Precipitation Runoff Modeling System model) used in the CRCC, each forced by 10 different global …

The Salish Sea Was Saturated With Respect To Aragonite In Pre-Industrial Times, Susan Allen Apr 2022

The Salish Sea Was Saturated With Respect To Aragonite In Pre-Industrial Times, Susan Allen

Salish Sea Ecosystem Conference

As the ocean takes up anthropogenic carbon dioxide, the pH decreases as does the saturation state of CaCO3 minerals, including aragonite. This process is commonly described as ocean acidification. Aragonite is used as a building material by many marine organisms, including pteropods, fish (otoliths), some corals, and larval oysters. The increase in inorganic carbon in the Salish Sea is moderate compared to other regions in the world because the incoming water is old. However, the naturally high carbon content of Pacific waters and the nonlinearities of the carbon system amplify the resultant effects. Here we investigate biogeochemical changes between the …

Introducing A Different Kind Of “Blob” In The Pnw – The Snark!, Skip Albertson Apr 2022

Introducing A Different Kind Of “Blob” In The Pnw – The Snark!, Skip Albertson

Salish Sea Ecosystem Conference

Puget Sound experienced progressively saltier conditions from 2017 to 2019 compared to time-averaged seasonal norms from 1999-2018. Reduced freshwater inflow from rivers drove much of these salinity increases; however, we report on another process raising salinity on the landward end of Case Inlet. Like “Meddies” in the Mediterranean Sea, evaporation leads to the formation of hypersaline blobs of surface water, known as “snarks”. Extreme low tides in the summer expose mudflats to elevated temperatures, providing a pathway to evaporating more water. When denser, hypersaline water sinks on the landward side of an estuary, it can cause inverse-estuarine conditions and increase …

Influence Of Lithology On Erosion Along The Dungeness Bluffs, Gabrielle Alampay, George Kaminsky, David Parks, Samuel Angel, Kathy Troost, Amanda Hacking

Salish Sea Ecosystem Conference

Erosion along the Dungeness Bluffs, located along the Strait of Juan de Fuca, poses a serious hazard to landowners living above. Concurrently, species such as forage fish depend on sediment input from bluff erosion to replenish the beaches in which they spawn. Between 2001 and 2012, the Dungeness bluffs eroded an average of 0.36 m/y, ranging from 0.0 to 1.88 m/y (Kaminsky et al., 2014; Parks, 2015). The steep bluffs in the area are ~30-80 m tall and are composed of glacial and interglacial sediment that vary in composition and strength.

Lagrangian Analysis Of Seasonal And Interannual Trends In Estuarine Flow Composition And Path Between Juan De Fuca Strait And Strait Of Georgia And Puget Sound, Becca Beutel Apr 2022

Lagrangian Analysis Of Seasonal And Interannual Trends In Estuarine Flow Composition And Path Between Juan De Fuca Strait And Strait Of Georgia And Puget Sound, Becca Beutel

Salish Sea Ecosystem Conference

Flow within Juan de Fuca Strait (JDF) accounts for the majority of the water entering and leaving the Salish Sea. As such, the health of the Sea’s diverse basins is strongly impacted by the composition and flux of the water within this strait. Complex flow at the mouth of the JDF means that a catalogue of Pacific currents, with different physical and chemical characteristics, play a role in the inflow. Within the Salish Sea phenomena such as variable river discharge and wind driven upwelling within the basins adds to the variability of the makeup and path of the water leaving. …
