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...

Controlled and in situ target strengths of the jumbo squid Dosidicus gigas and identification of potential acoustic scattering sources

Creator:: Benoit-Bird, Kelly J., Gilly, William F., and Au, Whitlow W. L.
Abstract:: This study presents the first target strength measurements of Dosidicus gigas, a large squid that is a key predator, a significant prey, and the target of an important fishery. Target strength of live, tethered squid was related to mantle length with values standardized to the length squared of −62.0, −67.4,...

An epibenthic sampler used to study the ontogeny of vertical migration of pandalus dordani (Decapoda caridea)

Creator:: Rothlisberg, Peter and Pearcy, William G.
Abstract:: Pandalis jordani Rathbun, like many other species of pandalid shrimps, undergo regular diel changes in their vertical distribution (Tegelberg and Smith 1957; Alverson et al. 1960; Pearcy 1970, 1972; Robinson in press). Little is known, however, about the vertical distribution and diel migrations of larval and juvenile shrimp, or at...

Relationship between oceanic mesozooplankton and energy of eddy fields

Creator:: Piontkovski, S. A., Williams, R., Peterson, William T., and Kosnirev, V. K.
Abstract:: The impact of mesoscale eddies on the spatial distribution of zooplankton biomass was analysed using data from the Arabian Sea and the Black Sea. The highest values of spatial variance of zooplankton biomass in the upper 100 to 150 m were found in regions with maximum available potential energy of...

Ocean distribution of the American shad (Alosa sapidissima) along the Pacific coast of North America

Creator:: Pearcy, William G. and Fisher, Joseph P.
Abstract:: We examined the incidental catches of American shad (Alosa sapidissima) taken during research cruises and in commercial and recreational landings along the Pacific coast of North America during over 30 years of sampling. Shad, an introduced species, was mainly found over the shallow continental shelf, and largest catches and highest...

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....

Prospects for Recovering Endemic Fishes Pursuant to the U.S. Endangered Species Act

Creator:: Williams, Jack E., Macdonald, Catherine A., Williams, Cindy Deacon, Weeks, Hal, Lampman, Georgina, and Sada, Don W.
Abstract:: If the success of the Endangered Species Act (ESA) is measured by the number of endangered species that have been recovered and delisted, then the act is not very successful. Only 15 species have been delisted because of recovery in the history of the ESA. The Borax Lake chub (Gila...

Submersible observations of deep-reef fishes of Heceta Bank, Oregon

Creator:: Pearcy, William G., Stein, David L., Hixon, Mark Anthony, Pikitch, Ellen K., Barss, William H., and Starr, Richard M.
Abstract:: Rockfishes, Sebastes spp.. were the most numerous and speciose fishes seen during 16 submersible dives from 64 to 305 m depth in the vicinity of Heceta Bank off the coast of Oregon. Dense schools of juvenile rockfishes and large yellowtail rockfish, S. flavidus, were observed only over rocky, high relief...

Errors in juvenile copepod growth rate estimates are widespread: problems with the Moult Rate method

Creator:: Hirst, A. G., Peterson, William T., and Rothery, P.
Abstract:: The Moult Rate (MR) method has been used widely to derive stage-specific growth rates in juvenile copepods. It is the most common field-based method. Unfortunately, the equation underlying the method is wrong and, consequently, large errors in juvenile growth rate estimates are widespread. The equation derives growth from the mean...

Fish-habitat associations on a deep reef at the edge of the Oregon continental shelf

Creator:: Tissot, Brian N., Hixon, Mark Anthony, Barss, William, and Stein, David L.
Abstract:: Heceta Bank is a large reef on the edge of the central Oregon continental shelf that supports a wide variety of commercial fisheries. Using the research submersible Delta, we studied fish abundances on Heceta Bank and the relationship between species composition of fish assemblages and bottom types. Cluster analysis indicated...
