A New Record of Planktic Foraminifera Community Response to Marine Heatwaves in the Northeast Pacific

Creator:: M. Kelsey Lane
Abstract:: Marine heat waves are forecasted to increase in frequency and intensity under future climate scenarios, but little is known about the impact of these events on the one of the most commonly used proxies of ocean temperature - foraminiferal assemblages. This research explores the planktic foraminifera community along the Newport...

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...

Comparison of larval development in domesticated and naturalized stocks of the Pacific oyster Crassostrea gigas exposed to high pCO₂ conditions

Creator:: Durland, Evan, Waldbusser, George, and Langdon, Chris
Abstract:: Ocean acidification (OA) has had significant negative effects on oyster populations on the west coast of North America over the past decade. Many studies have focused on the physiological challenges experienced by young oyster larvae in high pCO₂/low pH seawater with reduced aragonite saturation state (Ωarag), which is characteristic of...

Professional Development Training in Ocean Acidification: A Case Study of Marine Resource Managers

Creator:: Moses, Michael L.
Abstract:: Ocean acidification (OA) is the result of increasing concentrations of anthropogenic carbon dioxide (CO₂) emissions, leading to a suite of alterations to specific parameters of ocean chemistry, which can negatively impact many marine organisms and ecosystems. Understanding how to measure and monitor the chemistry of OA will require specialized education...

Capitalizing on Oregon’s Offshore Freshwater Bounty REnewable Food Energy Water on Land and Sea (REFEWLS)

Creator:: Blessing, Jacob M.
Abstract:: REFEWLS - REnewable Food Energy Water on Land and Sea Nexus This project will explore the connections between food, energy, and water uses along Oregon's mid coastal regions with a emphasis and focus on Newport. On average Newport uses approximately 2,000,000 gallons of water per day, but in the tourist...

Recruitment, Growth and Mortality of an Antarctic Hexactinellid Sponge, Anoxycalyx joubini

Creator:: Dayton, Paul K., Kim, Stacy, Jarrell, Shannon C., Oliver, John S., Hammerstrom, Kamille, Fisher, Jennifer L., O'Connor, Kevin, Barber, Julie S., Robilliard, Gordon, Barry, James, Thurber, Andrew R., and Conlan, Kathy
Abstract:: Polar ecosystems are sensitive to climate forcing, and we often lack baselines to evaluate changes. Here we report a nearly 50-year study in which a sudden shift in the population dynamics of an ecologically important, structure-forming hexactinellid sponge, Anoxycalyx joubini was observed. This is the largest Antarctic sponge, with individuals...

Ocean distribution of the American shad (Alosa sapidissima) along the Pacific coast of North America

Creator:: Pearcy, William G. and Fisher, Joseph P.
Abstract:: We examined the incidental catches of American shad (Alosa sapidissima) taken during research cruises and in commercial and recreational landings along the Pacific coast of North America during over 30 years of sampling. Shad, an introduced species, was mainly found over the shallow continental shelf, and largest catches and highest...

Controlled and in situ target strengths of the jumbo squid Dosidicus gigas and identification of potential acoustic scattering sources

Creator:: Benoit-Bird, Kelly J., Gilly, William F., and Au, Whitlow W. L.
Abstract:: This study presents the first target strength measurements of Dosidicus gigas, a large squid that is a key predator, a significant prey, and the target of an important fishery. Target strength of live, tethered squid was related to mantle length with values standardized to the length squared of −62.0, −67.4,...

Identification of Burrowing Shrimp Food Sources Along an Estuarine Gradient Using Fatty Acid Analysis and Stable Isotope Ratios

Creator:: Bosley, Katelyn M., Copeman, Louise A., Dumbauld, Brett R., and Bosley, Keith L.
Abstract:: Two species of burrowing shrimp occur in high densities in US West Coast estuaries, the ghost shrimp, Neotrypaea californiensis, and the blue mud shrimp, Upogebia pugettensis. Both species of shrimp are considered ecosystem engineers as they bioturbate and irrigate extensive galleries within the sediment. While their burrows comprise a dominant...

Seasonal distribution and environmental associations among late larval and juvenile rockfish (Sebastes spp.) off Oregon and Washington: new insights based on genetics

Creator:: Johansson, Mattias L., Litz, Marisa N. C., Brodeur, Richard D., Britt, Tristan A., Vanegas, Camilo A., Hyde, John R., and Banks, Michael A.
Abstract:: Cytochrome B sequence data (FASTA format) from the paper “Seasonal distribution and environmental associations among late larval and juvenile rockfish (Sebastes spp.) off Oregon and Washington: new insights based on genetics”. The data was generated from a sample of 2534 unknown, field collected late-larval and juvenile rockfishes from the Pacific...
