Utilizing cooperative fisheries research to monitor and understand harmful algal blooms along the Oregon coast

Creator:: Gilliland, Raquel C.
Abstract:: Harmful algal blooms (HABs) are a problem for coastal communities, the fishing industry, and coastal organisms. Pseudo-nitzschia spp. is a regularly occurring diatom in Oregon’s coastal waters. At times, Pseudo-nitzschia spp. can facultatively produce domoic acid, a neurotoxin that can bioaccumulate in the food chain. While regular shore-based sampling provides...

Management Applications of Remotely Sensed Dynamic Seascapes: Two Case Studies

Creator:: Klajbor, Willem C.
Abstract:: Dynamic seascapes, which are classified using a combination of remotely sensed data and model output, represent a potential tool for dynamic ecosystem-based management in marine systems. This work explores the utility of seascape classification in the context of marine resource management by examining two case studies: one involving biological relationships...

Detection of Physical and Biological Fronts in the Northern California Current System and the Drivers Behind Their Seasonal to Interannual Variability

Creator:: Jamil, Aliya L.
Abstract:: Oceanic fronts mark the boundary between two water masses and are often sites of complex bio-physical processes and multi-trophic level interactions, making them particularly important features in marine ecosystems. As global climate change induces multi-scale shifts in the driving physical mechanisms of fronts, spatiotemporal tracking of frontal variability can aid...

Intraseasonal Oscillations of ~20 days Revisited: The Jet Stream and its Ecological Implications along the Oregon Coast

Creator:: Herweck, Kendra
Abstract:: Intraseasonal oscillations in the atmosphere-ocean system can affect weather patterns and regional ecosystems. In turn, these oscillations can be affected by climate variability, resulting in additive and/or non-linear responses of regional ecosystems to climate forcing. In the Northern California Current, a strong correlation was identified between the location of the...

High-resolution Biological Net Community Production in the Pacific-influenced Arctic: A Multi-method Comparison

Creator:: Cynar, Haley
Abstract:: Patterns of primary productivity in the Arctic are expected to change with continued warming, yet productivity measurements are historically limited, both spatially and temporally. An established method of measuring net biological oxygen production, which can be used to estimate net community production (NCP) rates, is with an equilibrated inlet mass...

Oceanographic Drivers of Northern California Current Phytoplankton Communities and their Fatty Acid Composition: Implications for Northwest Fisheries

Creator:: Smoak, Rebecca T.
Abstract:: Micro-plankton are a crucial component of pelagic food webs, responding rapidly to environmental changes, and providing a first step in the acquisition and transfer of nutrients to life in the ocean. In addition to the uptake of carbon, phytoplankton provide essential fatty acids (FAs) that can limit the growth of...

Spatial and Temporal Dynamics of Broad-scale Predictive Models : Influences of Scale

Creator:: Hooper, Samuel
Abstract:: Developing accurate predictive distribution models requires adequately representing relevant spatial and temporal scales, as these scales are ultimately reflective of the relationships between distributions and influential environmental conditions. In this research, we considered both spatial and temporal scale and the influence each has on predicting broad-scale distributions of two disparate...

Connection to Community and Environment: How Work in the Seafood Processing Industry in Coos County, Oregon Creates a Sense of Place

Creator:: Johnson, Maria R.
Abstract:: Seafood processing is an important industry along the Oregon coast as it provides employment and seafood to coastal communities as well as to international markets. The industry has been an integral part of the identity of Coos County since the establishment of salmon canneries in the late 1800’s and has...

Dynamic seascapes : a quantitative framework for scaling pelagic ecology and biogeochemistry

Creator:: Kavanaugh, Maria T.
Abstract:: Understanding and modeling microbial responses and feedbacks to climate change is hampered by a lack of a framework in the pelagic environment by which to link local mechanism to large scale patterns. Where terrestrial ecology draws from landscape theory and practice to address issues of scale, the pelagic seascape concept...

Fishing for Hypoxia: Exploring Coastal Oxygen Dynamics and Predictability of Low Oxygen Episodes through a Partnership with the Oregon Dungeness Crab Fishing Fleet

Creator:: Stoltz, Linus O.
Abstract:: Coastal hypoxia, or low oxygen episodes pose a threat to marine resources in the Pacific Northwest. Previous research into nearshore oxygen dynamics have linked coastal upwelling to this seasonally occurring phenomenon, however the manifestation of hypoxic waters over coastal fishing grounds was not well understood. Through a partnership with Dungeness...
