Larval development in the Pacific oyster and the impacts of ocean acidification : differential genetic effects in wild and domesticated stocks

Creator:: Durland, Evan, Pierre De Wit,, Meyer, Eli, and Langdon, Chris
Abstract:: The adaptive capacity of marine calcifiers to ocean acidification (OA) is a topic of great interest to evolutionary biologists and ecologists. Previous studies have provided evidence to suggest that larval resilience to high pCO2 seawater for these species is a trait with a genetic basis and variability in natural populations....

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...

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...

Hydrothermal Discharge During Submarine Eruptions

Creator:: Baker, Edward T., Chadwick, Wi l l iam W. Jr., Cowen, James P., Dziak, Robert P., Rubin, Kenneth H., and Fornari, Daniel J.
Abstract:: Submarine volcanic eruptions and intrusions construct new oceanic crust and build long chains of volcanic islands and vast submarine plateaus. Magmatic events are a primary agent for the transfer of heat, chemicals, and even microbes from the crust to the ocean, but the processes that control these transfers are poorly...

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....

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...

Flux measurements of explosive degassing using a yearlong hydroacoustic record at an erupting submarine volcano

Creator:: Dziak, R. P., Baker, E. T., Shaw, A. M., Bohnenstiehl, D. R., Chadwick, W. W., Jr., Haxel, J. H., Matsumoto, H., and Walker, S. L.
Abstract:: The output of gas and tephra from volcanoes is an inherently disorganized process that makes reliable flux estimates challenging to obtain. Continuous monitoring of gas flux has been achieved in only a few instances at subaerial volcanoes, but never for submarine volcanoes. Here we use the first sustained (yearlong) hydroacoustic...

Hydroacoustic monitoring of oceanic spreading centers: Past, present, and future

Creator:: Dziak, Robert P., Bohnenstiehl, Delwayne R., and Smith, Deborah K.
Abstract:: Mid-ocean ridge volcanism and extensional faulting are the fundamental processes that lead to the creation and rifting of oceanic crust, yet these events go largely undetected in the deep ocean. Currently, the only means available to observe seafloor-spreading events in real time is via the remote detection of the seismicity...

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...

A latitudinal cline in the Chinook salmon (Oncorhynchus tshawytscha) Clock gene: evidence for selection on PolyQ length variants

Creator:: O'Malley, Kathleen G. and Banks, Michael A.
Abstract:: A critical seasonal event for anadromous Chinook salmon (Oncorhynchus tshawytscha) is the time at which adults migrate from the ocean to breed in freshwater. We investigated whether allelic variation at the circadian rhythm genes, OtsClock1a and OtsClock1b, underlies genetic control of migration timing among 42 populations in North America. We...
