Microsatellites Reveal Population Identity of Individual Pink Salmon to Allow Supportive Breeding of a Population at Risk of Extinction

Creator:: Olsen, Jeffrey B., Bentzen, Paul, Banks, Michael A., Shaklee, James B., and Young, Sewall
Abstract:: Efforts to restore depressed populations of Pacific salmon Oncorhynchus spp. are often hampered by the inability to assign population identity to individuals in an admixture. This knowledge is of particular concern in supportive breeding programs, in which misidentification of individuals to population may result in progeny of mixed heritage, which,...

Abstract:: The state of the California Current System (CCS) since spring 2011 has evolved in response to dissipation of La Niña through spring and summer, resurgence of cooler La Niña conditions in fall and winter, and finally a transition towards ENSO-neutral conditions in spring 2012. The resurgence of La Niña was...

State of the California Current 2010-2011: Regionally Variable Responses to a Strong (But Fleeting?) La Nina

Creator:: Bjorkstedt, Eric P., Goericke, Ralf, McClatchie, Sam, Weber, Ed, Watson, William, Lo, Nancy, Peterson, Bill, Emmett, Bob, Brodeur, Ric, Peterson, Jay, Litz, Marisa, Gomez-Valdez, Jose, Gaxiola-Castro, Gilberto, Lavaniegos, Bertha, Chavez, Francisco, Collins, Curtis A., Field, John, Sakuma, Keith, Warzybok, Pete, Bradley, Russell, Jahncke, Jaime, Bograd, Steven, Schwing, Franklin, Campbell, Gregory S., Hildebrand, John, Sydeman, William, Thompson, Sarah Ann, Largier, John L., Halle, Chris, Kim, Sung Yong, and Abell, Jeffrey
Abstract:: The state of the California Current system (CCS) since spring 2010 has evolved in response to the development of cooler La Nina following the dissipation of the relatively weak and short-lived El Nino event of 2009-2010. The 2009-2010 El Nino appears to have dissipated quite rapidly in early spring 2010,...

Acoustics variability of air gun signals recorded at intermediate ranges within the Lau Basin

Creator:: Bohnenstiehl, DelWayne R., Scheip, Corey M., Matsumoto, Haru, and Dziak, Robert P.
Abstract:: During January–February 2009, an active-source seismic survey was performed over the Eastern Lau Spreading Center in the Lau Back-Arc Basin (21°S, 176°S). Acoustic signals generated by the R/V Langseth's 36-gun pneumatic source array were recorded within the deep sound channel at offsets of 29–416 km. The local ocean acoustic environment...

Cold front induced changes on the Florida panhandle shelf during October 2008

Creator:: Kamykowski, D., Morrison, J. M., McCulloch, A. A., Nyadjro, E. S., Thomas, C. A., Sinclair, G. A., and Grabowski Pridgen, K.
Abstract:: A significant step transition between seasonally stratified and destratified hydrographic conditions occurred during an October 2008 cruise to the Florida Panhandle Shelf along a cross-shelf transect that was sampled before and after a cold front passed through the area. Meteorological measurements from nearby ocean and land-based stations characterized the event....

Marine, Estuarine, and Diadromous Fish Stocks at Risk of Extinction in North America (Exclusive of Pacific Salmonids)

Creator:: Musick, J. A., Harbin, M. M., Berkeley, S. A., Burgess, G. H., Eklund, A. M., Findley, L., Gilmore, R. G., Golden, J. T., Ha, D. S., Huntsman, G. R., McGovern, J. C., Sedberry, G. R., Parker, S. J., Poss, S. G., Sala, E., Schmidt, T. W., Weeks, H., and Wright, S. G.
Abstract:: The problem of extinction in the sea has been recognized only recently by the scientific community (Roberts and Hawkins 1999). For the last decade, the American Fisheries Society (AFS) has pursued an initiative to identify marine fish stocks that may be at risk of extinction in North America (Musick 1998;...

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...

Underwater acoustic records from the March 2009 eruption of Hunga Ha'apai-Hunga Tonga volcano in the Kingdom of Tonga

Creator:: Bohnenstiehl, DelWayne R., Dziak, Robert P., Matsumoto, Haru, and Lau, T.-K. Andy
Abstract:: A network of autonomous underwater hydrophones is used to monitor acoustic activity associated with Hunga Ha'apai-Hunga Tonga volcano during a period of 15 months. The data provide a continuous record spanning a surtseyan eruption (VEI 2) in March of 2009, which input ~10¹³ J of acoustic energy into the ocean...

Feeding Behavior, Prey Consumption, and Growth of Juvenile Red Hake

Creator:: Luczkovich, J. J. and Olla, B. L.
Abstract:: Juvenile red hake Urophycis chuss were collected while they were inhabiting sea scallops Placopecten magellanicus , and the effects of appetite and food availability on prey consumption and growth were examined under laboratory conditions. Fish took increasing amounts of live amphipods Gammarus annulatus with increasing periods of food deprivation up...

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...
