Marine Heatwaves Influence Depth Preferences of Chinook Salmon (Oncorhynchus tshawytscha)

Creator:: Teahan, Andrew
Abstract:: Marine heatwaves have become more common over the past several years. The 2014-2015 ‘warm blob’ had profound effects on marine ecosystems in the Northeast Pacific. Given the particular habitat needs of Chinook Salmon (Oncorhynchus tshawytscha) we wanted to examine the impacts of the heatwave on Chinook depth distribution. We examined...

Southern Ocean Science and Society: Case Studies at the Nexus of Research, Education, and Policy

Creator:: Hann, Ashley M.
Abstract:: Even in remote environments, human and natural systems are connected. Pressing environmental and social changes warrant the field of science to not only continue to enhance understanding of the natural world, but also consider the socio-ecological implications of research in the coupled human-natural system. Additionally, a need exists for communication...

Drivers of Euphausiid Abundance and Biomass in the Kitimat Fjord System, BC Canada

Creator:: Qualls, Katelyn M.
Abstract:: Euphausiids are recognized as essential components of marine food webs throughout the world’s oceans due to their role as prey for many species including whales, seabirds, and commercial fishes. The Kitimat Fjord System is an important fisheries area and is the only fjord habitat on the British Columbia coast that...

Impacts of Ocean Acidification and Warming on the Growth and Development of Oregon Pink Shrimp (Pandalus jordani) Larvae

Creator:: Nguyen, Michelle B.
Abstract:: Anthropogenic carbon dioxide emissions are causing ocean acidification (OA) and ocean warming, which have negative effects on the larvae of many marine invertebrates. Oregon pink shrimp (Pandalus jordani) currently encounter upwelling events that can result in pH values as low as 7.6, and, more recently, marine heat waves that raise...

Investigating the Paleoseismic Potential of Small, Southern Cascadia Lakes

Creator:: Ross, Ann Elizabeth Morey
Abstract:: Marine and coastal sedimentary archives show that the Cascadia Subduction Zone can generate great earthquakes of ~M9, most recently in 1700 CE, yet we still know little of the impacts of these events inland of the Pacific coast. Inland lakes have recently been exploited for their use as paleoseismic records...

Influence of upwelling-season coastal currents on near-bottom dissolved oxygen concentrations over a submarine bank

Creator:: Adams, Katherine A.
Abstract:: Wind-driven coastal upwelling brings subsurface water onto the central-Oregon shelf after the spring transition each year. This cold and salty source water is oxygen-poor, yet above the hypoxic threshold, dissolved oxygen < 1.4 ml l⁻¹. Once on the shelf, dissolved oxygen (DO) concentrations of upwelled near-bottom waters are modified by...

Subducting Seamounts and Heceta Bank: An Amphibious Seismic Tomography Experiment of the Central Oregon Forearc

Creator:: Nolan, Sarah
Abstract:: Studies reveal differences in slip segmentation and plate coupling along the Cascadia subduction zone. The segment between 44.0°N and 45.0°N exhibited reduced slip in the 1700 megathrust earthquake (Wang et al., 2013) and corresponds with previous rupture boundaries inferred from paleoseismic data (Leonard et al., 2010). Notably, this segment of...

Do gray whales count calories? Comparing energetic values of gray whale prey across two different feeding grounds in the eastern North Pacific

Creator:: Hildebrand, Lisa, Bernard, Kim S., and Torres, Leigh G.
Abstract:: Predators must consume enough prey to support costly events, such as reproduction. Meeting high energetic requirements is particularly challenging for migrating baleen whales as their feeding seasons are typically restricted to a limited temporal window and marine prey are notoriously patchy. We assessed the energetic value of the six most...

Informing and Enhancing Scientific and Management Understanding of Oregon’s Nearshore Groundfish Trawl Fishery by Engaging Local Ecological Knowledge

Creator:: Sjostrom, Anja J. C.
Abstract:: Oregon’s Coastal nearshore ecosystems are a nexus between living marine resources and coincident human recreational, industrial and socio-economic development. These nearshore regions also provide habitats vital to early life history stages of commercial non-whiting groundfish species, which supplied 21% of the Oregon fishing economy in 2018. The very shallow portions...

Metabolic balance of coastal Antarctic waters revealed by autonomous pCO₂ and ΔO₂/Ar measurements

Creator:: Tortell, Philippe D., Asher, Elizabeth C., Ducklow, Hugh W., Goldman, Johanna A. L., Dacey, John W. H., Grzymski, Joseph J., Young, Jodi N., Kranz, Sven A., Bernard, Kim S., and Morel, François M. M.
Abstract:: We use autonomous gas measurements to examine the metabolic balance (photosynthesis minus respiration) of coastal Antarctic waters during the spring/summer growth season. Our observations capture the development of a massive phytoplankton bloom and reveal striking variability in pCO₂ and biological oxygen saturation (ΔO₂/Ar) resulting from large shifts in community metabolism...
