Fishery-specific solutions to seabird bycatch in the U.S. West Coast sablefish fishery

Creator:: Good, Thomas P., Jannot, Jason E., Melvin, Edward F., Gladics, Amanda J., Suryan, Robert M., and Guy, Troy J.
Abstract:: Bird scaring lines (BSLs) protect longline fishing gear from seabird attacks, save bait, reduce incidental seabird mortality and are the most commonly prescribed seabird bycatch mitigation measure worldwide. We collaborated with fishermen to assess the efficacy of applying BSL regulations from the demersal longline sablefish fishery in Alaska to a...

Recent pre-recruit Pacific hake (Merluccius productus) occurrences in the Northern California Current suggest a northward expansion of their spawning area

Creator:: Phillips, A. Jason, Ralston, Stephen, Brodeur, Richard D., Auth, Toby D., Emmett, Robert L., Johnson, Carrie, and Wespestad, Vidar G.
Abstract:: Coastal Pacific hake (Merluccius productus) are known to spawn in the southern California Bight from January to March, migrate north during late spring and summer to feed off Oregon, Washington, and British Columbia, and then move back to southern California in the fall. Juvenile Pacific hake nursery areas have been...

Development and Evaluation of a Static Land-Based Aquaculture System for Pacific Dulse (Devaleraea mollis): Environmental and Nutrient Requirements

Creator:: Chatfield, Marcus W.
Abstract:: Devaleraea mollis (Pacific Dulse) is becoming a popular food for human consumption. Previously, Pacific Dulse has been used as a nutrient source for cultured abalone species, with some historical food use by indigenous peoples, while the closely related Atlantic dulse (Palmaria palmata) has a long-documented history of use in cuisine...

Seismic precursors and magma ascent before the April 2011 eruption at Axial Seamount

Creator:: Dziak, R. P., Haxel, J. H., Bohnenstiehl, D. R., Chadwick, W. W., Jr., Nooner, S. L., Fowler, M. J., Matsumoto, H., and Butterfield, D. A.
Abstract:: Volcanoes at spreading centres on land often exhibit seismicity and ground inflation months to years before an eruption, caused by a gradual influx of magma to the source reservoir¹⁻⁴. Deflation and seismicity can occur on time scales of hours to days, and result from the injection of magma into adjacent...

Differential gene expression between fall- and spring-run Chinook salmon assessed by long serial analysis of gene expression

Creator:: Bernier, Jeremiah C., Birkeland, Shanda R., Cipriano, Michael J., McArthur, Andrew G., and Banks, Michael A.
Abstract:: Of all Pacific salmonids, Chinook salmon Oncorhynchus tshawytscha display the greatest variability in return times to freshwater. The molecular mechanisms of these differential return times have not been well described. Current methods, such as long serial analysis of gene expression (LongSAGE) and microarrays, allow gene expression to be analyzed for...

Volcanic Eruptions in the Deep Sea

Creator:: Rubin, Kenneth H., Soule, S. Adam, Chadwick, William W., Jr., Fornari, Daniel J., Clague, David A., Embley, Robert W., Baker, Edward T., Perfit, Michael R., Caress, David W., and Dziak, Robert P.
Abstract:: Volcanic eruptions are important events in Earth’s cycle of magma generation and crustal construction. Over durations of hours to years, eruptions produce new deposits of lava and/or fragmentary ejecta, transfer heat and magmatic volatiles from Earth’s interior to the overlying air or seawater, and significantly modify the landscape and perturb...

Repeat bathymetric surveys at 1-metre resolution of lava flows erupted at Axial Seamount in April 2011

Creator:: Caress, David W., Clague, David A., Paduan, Jennifer B., Martin, Julie F., Dreyer, Brian M., Chadwick, William W., Jr., Denny, Alden, and Kelley, Deborah S.
Abstract:: At sites with frequent submarine volcanic activity, it is difficult to discern between new and pre-existing lava flows. In particular, the distribution of the fissures from which lava erupts, the routes taken by lava flows and the relationship between the new flows and the pre-existing seafloor bathymetry are often unclear....

Seafloor deformation and forecasts of the April 2011 eruption at Axial Seamount

Creator:: Chadwick, William W., Jr., Nooner, Scott L., Butterfield, David A., and Lilley, Marvin D.
Abstract:: Axial Seamount is an active submarine volcano located at the intersection between the Cobb hotspot and the Juan de Fuca spreading centre in the northeast Pacific Ocean1, 2. The volcano has been closely monitored since it erupted in 1998 (refs 3, 4). Since then, Axial Seamount seemed to exhibit a...

Long Term Trends and Sources of Sound in United States Waters

Creator:: Haver, Samara M.
Abstract:: Passive acoustic monitoring is a valuable tool for observing the status of marine environments. Comparisons of underwater soundscapes over temporal and spatial scales can provide data to inform marine conservation efforts, including protection of threatened and endangered species. This dissertation utilizes passive acoustic data collected via a broadly spaced array...

Submarine landslide triggered by volcanic eruption recorded by in situ hydrophone

Creator:: Chadwick, W.W. Jr., Dziak, R.P., Haxel, J.H., Embley, R.W., and Matsumoto, H.
Abstract:: NW Rota-1 is a submarine volcano in the Mariana volcanic arc that is notable as the site where underwater explosive eruptions were first witnessed in A. D. 2004. After years of continuous low-level eruptive activity, a major landslide occurred at NW Rota-1 in August 2009, triggered by an unusually large...
