Is there a common response to ultraviolet-B radiation by marine phytoplankton?

Creator:: Behrenfeld, Michael J., Chapman, John W., Hardy, John T., and Lee II, Henry
Abstract:: Global increases in ultraviolet-B radiation (UVBR) have the potential to alter marine primary production and to affect carbon cycles and marine trophic dynamics. Estimates of UVBR induced photoinhibition have varied greatly, indicating that a common dose-response by marine phytoplankton may not occur from place to place. An action spectrum describing...

Bias and Precision of Estimates from an Age-Structured Stock Assessment Program in Relation to Stock and Data Characteristics

Creator:: Yin, Yanshui and Sampson, David B.
Abstract:: Assessments for many U.S. Pacific coast groundfish stocks have been developed using the statistical catch-at-age method known as Stock Synthesis. This study used Monte Carlo simulation and a fractional factorial experiment to evaluate the effects of input data errors and stock characteristics on bias and precision in estimates of ending...

Gear-Related Mortality in Selective Fisheries for Ocean Salmon

Creator:: Lawson, Peter W. and Sampson, David B.
Abstract:: In ocean fisheries for Pacific salmon Oncorhynchus spp., there can be several forms of gear-related mortality. Much research effort has been directed at estimating mortality rates for salmon that are hooked and then released. Also potentially important but not easily measured is mortality of fish that escape from the hook...

The Center for Independent Experts: The National External Peer Review Program of NOAA's National Marine Fisheries Service

Creator:: Brown, Stephen K., Shivlani, Manoj, Die, David, Sampson, David B., and Ting, Tina A.
Abstract:: Requirements are growing for peer review of the science used for governmental management decisions. This is particularly true for fisheries science, where management decisions are often controversial. The National Oceanic and Atmospheric Administration's National Marine Fisheries Service instituted the Center for Independent Experts (CIE) in 1998 as a national peer-review...

Predator and shelter-size effects on coral reef fish and spiny lobster prey

Creator:: Eggleston, David B., Lipcius, Romuald N., and Grover, Jill J.
Abstract:: Population dynamics of coral reef fishes and spiny lobster appear to be determined by variable recruitment interacting with post-settlement processes, particularly predation. The risk of predation may be modified by the scaling between prey and shelter size, which enhances the protective capacity of a reef. We experimentally tested these predictions...

Winter dispersal and activity patterns of post-breeding black-legged kittiwakes Rissa tridactyla from Prince William Sound, Alaska

Creator:: McKnight, Aly, Irons, David B., Allyn, Andrew J., Sullivan, Kelsey M., and Suryan, Robert M.
Abstract:: As colony-specific wintering ecology of small and medium-sized seabirds is poorly understood, it has been generally assumed that winter conditions have the same effect on all individuals from any given colony. However, advances in global positioning technology now allow researchers to investigate movements of smaller seabirds. We tracked black-legged kittiwakes...

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....

Effects of physical gradients on the production dynamics of sediment-associated algae

Creator:: Davis, Michael W. and McIntire, C. David
Abstract:: Sediment-associated microalgal biomass expressed as chlorophyll a concentration, total organic matter concentration expressed as ash-free dry weight, and hourly rates of net community primary production and community oxygen consumption were measured at monthly intervales at medium sand, fine sand, and silt sites between 0.5 and 2.0 m above MLLW during...

Genetic Analyses Provide Insight into the Early Ocean Stock Distribution and Survival of Juvenile Coho Salmon off the Coasts of Washington and Oregon

Creator:: Van Doornik, Donald M., Teel, David J., Kuligowski, David R., Morgan, Cheryl A., and Casillas, Emundo
Abstract:: Estimating the stock proportions of mixed-stock fishery samples by means of genetic stock identification has played an important role in the management of salmon fisheries. In addition, stock identification of individual fish has applications for population studies, forensic cases, and management issues. We examined 11 microsatellite DNA loci in 84...

Estimating minke whale (Balaenoptera acutorostrata) boing sound density using passive acoustic sensors

Creator:: Martin, Stephen W., Marques, Tiago A., Thomas, Len, Morrissey, Ronald P., DiMarzio, Nancy, Moretti, David, Mellinger, David K., and Jarvis, Susan
Abstract:: Density estimation for marine mammal species is performed primarily using visual distance sampling or capture-recapture. Minke whales in Hawaiian waters are very difficult to sight; however, they produce a distinctive “boing” call, making them ideal candidates for passive acoustic density estimation. We used an array of 14 bottom-mounted hydrophones, distributed...
