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....

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...

Salinity adaptation of the invasive New Zealand mud snail (Potamopyrgus antipodarum) in the Columbia River estuary (Pacific Northwest, USA): physiological and molecular studies

Creator:: Hoy, Marshal, Boese, Bruce L., Taylor, Louise, Reusser, Deborah, and Rodriguez, Rusty
Abstract:: In this study, we examine salinity stress tolerances of two populations of the invasive species New Zealand mud snail Potamopyrgus antipodarum, one population from a high salinity environment in the Columbia River estuary and the other from a fresh water lake. In 1996, New Zealand mud snails were discovered in...

An Evaluation of the Influence of Stock Origin and Outmigration History on the Disease Susceptibility and Survival of Juvenile Chinook Salmon

Creator:: Dietrich, Joseph P., Boylen, Deborah A., Thompson, Donald E., Loboschefsky, Erik J., Bravo, Claudia F., Spangenberg, Dina K., Ylitalo, Gina M., Collier, Tracy K., Fryer, Derek S., Arkoosh, Mary R., and Loge, Frank J.
Abstract:: Various methods have been developed to mitigate the adverse effects of the Federal Columbia River Power System on juvenile Pacific salmon out-migrating through the Columbia River basin. In this study, we found that hatchery-reared spring Chinook salmon Oncorhynchus tshawytscha in the river are in varying degrees of health, which may...

Survey of Pathogens in Hatchery Chinook Salmon with Different Out-Migration Histories through the Snake and Columbia Rivers

Creator:: Van Gaest, Ahna L., Dietrich, Joseph P., Thompson, D. E., Boylen, Deborah A., Strickland, Stacy A., Collier, T. K., Loge, F. J., and Arkoosh, Mary R.
Abstract:: The operation of the Federal Columbia River Power System (FCRPS) has negatively affected threatened and endangered salmonid populations in the Pacific Northwest. Barging Snake River spring Chinook salmon Oncorhynchus tshawytscha through the FCRPS is one effort to mitigate the effect of the hydrosystem on juvenile salmon out-migration. However, little is...

The application of GIS and spatiotemporal analyses to investigations of unusual marine mammal strandings and mortality events

Creator:: Norman, Stephanie A., Huggins, Jessie, Carpenter, Tim E., Case, James T., Lambourn, Dyanna M., Rice, Jim, Calambokidis, John, Gaydos, Joseph K., Hanson, M. Bradley, Duffield, Deborah A., Dubpernell, Sandra, Berta, Susan, and Klope, Matt
Abstract:: In 2006–2007, an unusually high number of harbor porpoises (Phocoena phocoena) stranded along the Washington and Oregon coastlines. Spatiotemporal analyses were used to examine their ability to detect clusters of porpoise strandings during an unusual mortality event (UME) in the Pacific Northwest using stranding location data. Strandings were evaluated as...

Characteristics of three rhabdoviruses from snakehead fish Ophicephalus striatus

Creator:: Kasornchandra, J., Engelking, H. M., Lannan, C. N., Rohovec, J. S., and Fryer, J. L.
Abstract:: Protein profiles and serological characteristics of 3 rhabdoviruses from snakehead fish Ophicephalus striatus were determined and compared to 5 known fish rhabdoviruses and 1 mammalian rhabdovirus. The snakehead rhabdovirus (SHRV) exhibited a bacilliform morphology and a Lyssavirus-type protein profile. The ulcerative disease rhabdovirus isolates (UDRV-BP and UDRV-19) were indistinguishable and...

Volcanic Eruptions in the Deep Sea

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...

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...
