Influence of Upwelling-Season Coastal Currents on Near-Bottom Dissolved Oxygen Concentrations Over a Submarine Bank

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 physical and biological shelf processes, such as advection, mixing and microbial respiration.

Biologically Active Metabolites from Marine Microorganisms: Methods to Identify Drug Leads and Chemical Signals

Microbial natural products represent a massive repository of unique chemical scaffolds with corresponding diverse biological functions. However, in the past decade the development of natural products into new therapeutics has dwindled, in part due to the challenges posed by high rediscovery rates and low throughput associated with classical bioassay-guided fractionation methods. Recent research shows that most microbes express only a fraction of their total biosynthetic potential under standard monophyletic culture conditions.

Communicating Oceanographic Research Through Film: The Role of Film in Helping Scientists Develop and Meet Their Broader Impacts Goals

Funding agencies, specifically the National Science Foundation (NSF), are placing particular emphasis on the societal relevance and broader applications of scientific research, otherwise known as Broader Impacts (BIs). Scientists are required to address the BIs merit review criterion in their research proposals or they will not get funded. However, many scientists perceive the BIs criterion to be confusing and daunting, and developing activities to meet these requirements is often not within their expertise.

Dose of Reality: What Can We Learn from Educational and Veterinary Pet Owners to Guide More Effective Environmental Stewardship of Pharmaceutical and Personal Care Products (PPCPs)?

Improper disposal of unused human and pet pharmaceuticals and personal care products (PPCPs) are an emerging public and watershed health threat around the world. Although some waste stream reduction programs such as PPCPs “take-back” exist, there is limited research in current programs on reducing the entry of PPCPs into the environment that focuses on what motivates people - specifically pet owners - to take stewardship actions with their pet PPCPs.  . . .

Coupled Wave and Surge Modeling of Tillamook Bay, Oregon: Extreme Events and Climate Change Impacts

Estuaries represent the confluence of land and ocean environments and encompass a number of complex interactions amongst tides, winds, offshore waves and the riverine contributions, all of which contribute to total water levels (TWLs).The study of TWLs and the relative weight of its components can assist local comm

Interactions of Wind-Driven and Tidally-Driven Circulation in the Oregon Coastal Ocean

Influences of tidal and slower (subtidal) oceanic flows over the continental shelf and slope off Oregon are studied using a high-resolution ocean circulation model and comparative model-data analyses. The model is based on the Regional Ocean Modeling System (ROMS), a fully nonlinear, three-dimensional model (using hydrostatic and Boussinesq approximations).

Seasonal Hydrography and Hypoxia of Coos Bay, Oregon

The recent rise of inner shelf hypoxia in the California Current System has caused concern within the scientific community, sparking a surge in studies addressing the issue. While regional studies of hypoxia abound, relatively little attention has been focused on the smaller coastal estuarine systems in the Pacific Northwest. Here, we present results fromCoos Bay, a small, highly seasonal estuary on the southern Oregon coast. 


Evaluating the Data-Poor Fishery Stock Assessment Method, DB-SRA

Depletion-Based Stock Reduction Analysis (DB-SRA; Dick and MacCall, 2011) is a catch-only fisheries stock assessment model that has been developed to estimate an overfishing limit (OFL) in data-poor situations. DB-SRA projects the biomass trajectories of a stock by means of a catch time series and five parameters: the instantaneous, per annum, rate of natural mortality (M), age at 50% maturity, FMSY/M, BMSY/B0, and the predicted depletion of the stock from its unfished condition.
