Overlap of North Pacific albatrosses with the U.S. west coastgroundfish and shrimp fisheries

Creator:: Guy, T. J., Jennings, S. L., Suryan, R. M., Melvin, E. F., Bellman, M. A., Ballance, L. T., Blackie, B. A., Croll, D. A., Deguchi, T., Geernaert, T. O., Henry, R. W., Hester, M., Hyrenbach, K. D., Jahncke, J., Kappes, M. A., Ozaki, K., Roletto, J., Sato, F., Sydeman, W. J., and Zamon, J. E.
Abstract:: We used a combination of seabird data (both fishery-dependent and fishery-independent) and fishing-effort data to evaluate the relative fisheries risk of five west coast groundfish fisheries and oneshrimp fishery to black-footed (Phoebastria nigripes), short-tailed (P. albatrus) and Laysan albatrosses(P. immutabilis). To assess risk, an overlap index was derived as the...

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...

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...

Linking predators to seasonality of upwelling: Using food web indicators and path analysis to infer trophic connections

Creator:: Thompson, Sarah Ann, Sydeman, William J., Santora, Jarrod A., Black, Bryan A., Suryan, Robert M., Calambokidis, John, Peterson, William T., and Bograd, Steven J.
Abstract:: Upwelling in eastern boundary current systems is a primary driver of ecosystem productivity. Typically, peak upwelling occurs during spring and summer, but winter upwelling may also be important to ecosystem functions. In this study, we investigated the hypothesis that winter and spring/summer upwelling, operating through indirect trophic interactions, are important...

State of the California Current 2011–2012: Ecosystems Respond To Local Forcing as La Nina Wavers and Wanes

Creator:: Bjorkstedt, Eric P., Goericke, Ralf, McClatchie, Sam, Weber, Ed, Watson, William, Lo, Nancy, Peterson, William T., Brodeur, Richard D., Auth, Toby, Fisher, Jennifer, Morgan, Cheryl, Peterson, Jay, Largier, John, Bograd, Steven J., Durazo, Reginaldo, Gaxiola-Castro, Gilberto, Lavaniegos, Bertha, Chavez, Francisco P., Collins, Curtis A., Hannah, Bob, Field, John, Sakuma, Keith, Satterthwaite, Will, O'Farrell, Michael, Hayes, Sean, Harding, Jeff, Sydeman, William J., Thompson, Sarah Ann, Warzybok, Pete, Bradley, Russell, Jahncke, Jaime, Golightly, Richard T., Schneider, Stephanie R., Suryan, Robert M., Gladics, Amanda J., Horton, Cheryl A., Kim, Sung Yong, Melin, Sharon R., DeLong, Robert L., and Abell, Jeffrey
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...

Management of Pacific Rockfish

Creator:: Parker, S. J., Berkeley, S. A., Golden, J. T., Gunderson, D. R., Heifetz, J., Hixon, M. A., Larson, R., Leaman, B. M., Love, M. S., Musick, J. A., O'Connell, V. M., Ralston, S., Weeks, H. J., and Yoklavich, M. M.
Abstract:: The American Fisheries Society (AFS) recognizes the need for conservative and robust management of Pacific rockfishes because of naturally low population growth, the overfished state of many of the stocks, and complex nature of the mixed-stock fisheries (60-plus species). The AFS recommends that catch information be collected on a species-specific...

Tracking North Pacific Humpback Whales To Unravel Their Basin-Wide Movements

Creator:: Palacios, Daniel M., Mate, Bruce R., Baker, C. Scott, Hayslip, Craig E., Follett, Thomas M., Steel, Debbie, Lagerquist, Barbara A., Irvine, Ladd M., and Winsor, Martha H.
Abstract:: In 2014, Oregon State University (OSU) initiated a multi-year project to study humpback whale (Megaptera novaeangliae) migrations in the North Pacific Ocean using satellite tracking technology in combination with genetic and photo-identification (photo-ID) analyses. The study is highly relevant to management, given the need for new information arising from the...

Identification of Burrowing Shrimp Food Sources Along an Estuarine Gradient Using Fatty Acid Analysis and Stable Isotope Ratios

Creator:: Bosley, Katelyn M., Copeman, Louise A., Dumbauld, Brett R., and Bosley, Keith L.
Abstract:: Two species of burrowing shrimp occur in high densities in US West Coast estuaries, the ghost shrimp, Neotrypaea californiensis, and the blue mud shrimp, Upogebia pugettensis. Both species of shrimp are considered ecosystem engineers as they bioturbate and irrigate extensive galleries within the sediment. While their burrows comprise a dominant...

Waning magmatic activity along the Southern Explorer Ridge revealed through fault restoration of rift topography

Creator:: Deschamps, A., Tivey, M. A., Chadwick Jr., W. W., and Embley, R. W.
Abstract:: We combine high-resolution bathymetry acquired using the Autonomous Underwater Vehicle ABE with digital seafloor imagery collected using the remotely operated vehicle ROPOS across the axial valley of the Southern Explorer Ridge (SER) to infer the recent volcanic and tectonic processes. The SER is an intermediate spreading ridge located in the...

A taxonomic and distributional study of the rhodolith-forming species Lithothamnion muelleri (Corallinales, Rhodophyta) in the Eastern Pacific Ocean

Creator:: Robinson, Nestor M., Hansen, G. I., Fernandez-Garcia, C., and Riosmena-Rodriguez, R.
Abstract:: Lithothamnion rnuelleri is reported for the first time as one of the main components of rhodolith beds along the Eastern Pacific Ocean based on samples from Washington State (USA), Pacific Baja California (Mexico), southern Nicaragua, and Costa Rica. Individual rhodoliths ranged from fruticose to lumpy in morphology, and bi-sporangial, tetrasporangial,...
