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...

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...

Coordinated nocturnal behavior of foraging jumbo squid Dosidicus gigas

Creator:: Benoit-Bird, Kelly J. and Gilly, William F.
Abstract:: We used split-beam acoustic techniques to observe free-swimming of jumbo squid Dosidicus gigas during 4 cruises in the Gulf of California. Four-dimensional spatio-temporal data revealed that at night in shallow water, jumbo squid were using ascending, spiral-like swimming paths to emerge from extremely dense aggregations, and were likely foraging on...

Interannual variations in phytoplankton community structure in the northern California Current during the upwelling seasons of 2001−2010

Creator:: Du, Xiuning, Peterson, William, and O'Higgins, Linda
Abstract:: Phytoplankton species were enumerated from 72 samples collected biweekly during the upwelling season (May to August) of 2001−2010 to test for effects of interannual variations in upwelling and decadal basin-scale variability on phytoplankton species composition and community structure. Cluster analysis of phytoplankton community structure identified 7 groups; 1 group was...

Biological indicators of the timing and direction of warm-water advection during the 1997/1998 El Niño off the central Oregon coast, USA

Creator:: Keister, Julie E., Johnson, Travis B., Morgan, Cheryl A., and Peterson, William T.
Abstract:: Unusual collections of several euphausiid, chaetognath, and copepod species help elucidate the effects of the strong 1997/1998 El Niño off the central Oregon, USA, coast. Furcilia of Nyctiphanes simplex, a euphausiid typically found only as far north as central California, were collected in bi-weekly nearshore samples between December 1997 and...

Biological and physical ocean indicators predict the success of an invasive crab, Carcinus maenas, in the northern California Current

Creator:: Yamada, Sylvia Behrens, Peterson, William T., and Kosro, P. Michael
Abstract:: An introduced population of European green crabs Carcinus maenas was established in San Francisco Bay (California, USA) prior to 1989. Subsequently, their larvae were likely carried northward into the embayments of Oregon, Washington (USA), and British Columbia (Canada) by the unusually strong Davidson Current during the winter of the El...

New approach for using remotely sensed chlorophyll a to identify seabird hotspots

Creator:: Suryan, Robert M., Santora, Jarrod A., and Sydeman, William J.
Abstract:: Satellite imagery of chlorophyll a concentration (chl a) provides the only holistic perspective of productivity in marine ecosystems worldwide, yet its utility for understanding and predicting the distribution of upper trophic-level predators remains equivocal. We tested the hypothesis that remotely sensed chl a measurements spanning a decade can predict marine...

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...

When is bigger better? Early marine residence of middle and upper Columbia River spring Chinook salmon

Creator:: Tomaro, Londi M., Teel, David J., Peterson, William T., and Miller, Jessica A.
Abstract:: Early ocean residence is considered a critical period for juvenile salmon although specific survival mechanisms are often unidentified and may vary by species or life stage. Columbia River spring-run Chinook salmon Oncorhynchus tshawytscha abundance has declined dramatically since the early 1900s. To elucidate mechanisms of early marine survival, we tested...

Onshore-offshore variations in copepod community structure off the Oregon coast during the summer upwelling season

Creator:: Morgan, Cheryl A., Peterson, William T., and Emmett, Robert L.
Abstract:: During the summer of 1994, 1996, and 1997, we conducted hydrographic and plankton surveys of the upper 70 m in the nearshore, the continental shelf, and off shelf oceanic waters off Oregon, USA. Copepod densities and biomass were estimated along 4 transects from each cruise. The on shelf copepod biomass...
