While sophisticated tools are used to monitor behavioral changes of large marine vertebrates, determining whether these changes are meaningful for management and conservation is challenging. The Population Consequences of Disturbance model proposed a bioenergetics model to detect biologically meaningful population responses, where disturbance costs are linked to lost energy. The...
This resolution is a tribute to the accomplishments and memory of Dr. Lavern J. Weber, first resident director of the Hatfield Marine Science Center. The House bill was subsequently adopted by the Oregon Senate.
Stabilization of the Yaquina Bay shoreline along the northeastern edge of the Hatfield Marine Science Center (HMSC) campus became necessary to halt erosion that threatened both HMSC critical infrastructure (seawater storage tank) and public access to the HMSC Nature Trail. A Dynamic Revetment (gravel beach) was installed in November, 2011...
A majority of the world’s largest net-based fisheries target planktivorous forage fish that serve as a critical trophic link between the plankton and upper-level consumers such as large predatory fishes, seabirds, and marine mammals. Because the plankton production that drives forage fish also drives jellyfish production, these taxa often overlap...
We evaluated the external signs of barotrauma and 48-h post-recompression survival for 17 54 canary and 81 yelloweye rockfish captured at depths of 46-174 m, much deeper than a 18 similar prior experiment, but within the depth range of recreational fishery catch and 19 discard. Survival was measured using specialized...
A case history of ambient status and trends monitoring is presented for the South Slough estuary (southern Oregon). Datasets collected over the past decade by the South Slough National Estuarine Research Reserve / System-Wide Monitoring program (SWMP) include real-time measurements (every 5 min) of several meteorological parameters (air temperature, relative...
Marine Team is a student effort to examine spatial and temporal variation of fish species within Yaquina Bay. Marine Team was developed at OSU as a seminar course with a field sampling component, to help students of marine ecology get “hands on” experience with data collection and analysis. We set...
Status (as of 2006):
The current weather station has been in operation at HMSC since 1996. The weather instrument sensors are mounted on and under the roof of the Guin Library. The sensors are made by Davis instruments, a leading manufacturer of home quality instruments.
Up to the minute current...
Scientists at EPA’s National Health and Environmental Effects Research Laboratory, Western Ecology Division (WED) have been studying seafloor (benthic) habitats in Yaquina estuary for several years. Those studies were conducted as parts of several research projects, including: effects of contaminated sediments on benthic invertebrates, effects of nutrient enrichment on estuarine...
The program started around high use beaches to monitor fecal bacteria contamination because people including Surfers were getting sick. This was really a problem of poor planning and overdevelopment in coastal communities and was eventually addressed in the Clean Water Act. All states were mandated to monitor water quality particularly...
Researchers from the Pacific Coastal Ecology Branch, Environmental Protection Agency in Newport presented results of multi-year cruises as will other time-series data.
This is a description of the physical setting and distribution of plant and animal species near the mouth of the Salmon River. Intertidal invertebrates are emphasized. A more marine location is contrasted with a more estuarine site.
Little data exists to document the nature of sound generated by vibratory pile driving and the response salmon to that sound. The construction of a new pier at Oregon State University's Hatfield Marine Science Center in 1996 offered the opportunity to monitor the sound. The findings were then related to...

We evaluated how the use of bait as a fish attractant influenced the species and size composition 20 of demersal fishes viewed with a stereo video lander, at 160 sampling sites at Stonewall Bank, a 21 deepwater rocky reef complex in Oregon waters. We also studied the effectiveness of stereo...
These documents resulted from a summer 2013 internship for a OSU Systems Engineering student. Mr. Applegate was charged with documenting the existing seawater system at the Hatfield Marine Science Center and recommending efficiency upgrades. He produced a written report with various appendices containing system documentation and recommendations and a map....
We used a combination of seabird data (both fishery-dependent and fishery-independent) and fishing-effort data to evaluate the relative fisheries risk of five west coast groundfish fisheries and oneshrimp fishery to black-footed (Phoebastria nigripes), short-tailed (P. albatrus) and Laysan albatrosses(P. immutabilis). To assess risk, an overlap index was derived as the...
Differences in the chemical composition of calcified skeletal structures (e.g. shells, otoliths) have proven useful for reconstructing the environmental history of many marine species. However, the extent to which ambient environmental conditions can be inferred from the elemental signatures within the vertebrae of elasmobranchs (sharks, skates, rays) has not been...
