Responses by Pacific Halibut to Air Exposure: Lack of Correspondence among Plasma Constituents and Mortality

Creator:: Davis, Michael W. and Schreck, Carl B.
Abstract:: Age-1 and age-2 Pacific halibut Hippoglossus stenolepis were exposed to a range of times in air (0-60 min) and air temperatures (10 degrees C or 16 degrees C) that simulated conditions on deck after capture to test for correspondence among responses in plasma constituents and mortality. Pacific halibut mortality generally...

Fine-scale variability at 140°W in the Equatorial Pacific

Creator:: Chereskin, T. K., Moum, James N., Stabeno, P. J., Caldwell, Douglas R., Paulson, C. A., Regier, L. A., and Halpern, D.
Abstract:: In November-December 1984 we carried out an intensive 12-day upper ocean sampling program on the equator at 140°W as part of the Tropic Heat Experiment. From our observations we constructed hourly averaged profiles of temperature, salinity, σ₁, turbulent kinetic energy dissipation rate, and horizontal velocity. These data were used to...

A comparison of the behavior and survival of juvenile coho salmon (Oncorhynchus kisutch) and steelhead trout (O. mykiss) in a small estuary system

Creator:: Clements, Shaun, Stahl, Thomas, and Schreck, Carl B.
Abstract:: We used radio and acoustic telemetry to study the behavior and survival of wild steelhead trout (Oncorhynchus mykiss) and hatchery coho salmon (Oncorhynchus kisutch) and steelhead outmigrants in a small coastal estuary during two years. Survival was generally low for hatchery fish but more variable, both within and between years,...

High electron mobility W-doped In₂O₃ thin films by pulsed laser deposition

Creator:: Newhouse, Paul F., Park, C.-H., Keszler, Douglas A., Tate, J., Nyholm, P. S., and Tate, Janet
Abstract:: High electron mobility thin films of In₂₋ₓWₓO₃₊y(0≤x≤0.075) were prepared on amorphous SiO₂ and single-crystal yttria-stablized zirconia (001) substrates by pulsed laser deposition. Mobilities ranged between 66 and 112 cm² /Vs depending on the substrate type and deposition conditions, and the highest mobility was observed at a W-dopant concentration of x~0.03....

Primary Production Estimates from Recordings of Solar-Stimulated Fluorescence in the Equatorial Pacific at 150°W

Creator:: Stegmann, P. M., Lewis, M. R., Davis, C. O., and Cullen, J. J.
Abstract:: Biological, optical, and hydrographical data were collected on the WEC88 cruise along 150°W and during a 6-day time series station on the equator during February/March 1988. This area was characterized by a subsurface chlorophyll maximum (SCM), located at 50–70 m depth at the equator and descending down to 120–125 m...

Capture-Related Stressors Impair Immune System Function in Sablefish

Creator:: Lupes, Sarah C., Davis, Michael W., Olla, Bori L., and Schreck, Carl B.
Abstract:: The sablefish Anoplopoma fimbria is a valuable North Pacific Ocean species that, when not targeted in various commercial fisheries, is often a part of discarded bycatch. Predictions of the survival of discarded fish are dependent on understanding how a fish responds to stressful conditions. Our objective was to describe the...

Comparison of Predator Avoidance Capabilities with Corticosteroid Levels Induced by Stress in Juvenile Coho Salmon

Creator:: Olla, Bori L., Davis, Michael W., and Schreck, Carl B.
Abstract:: The relationship between predator avoidance deficits induced by a simple handling stress and the level of plasma corticosteroids was determined for juvenile coho salmon Oncorhynchus kisutch. Groups of fish were held out of water for 1 min, then allowed to recover from this stress for 1, 90, or 240 min....

Discard Mortality of Trawl-Caught Lingcod in Relation to Tow Duration and Time on Deck

Creator:: Parker, Steven J., Rankin, Polly S., Hannah, Robert W., and Schreck, Carl B.
Abstract:: The lingcod Ophiodon elongatus is a benthic marine fish commonly caught by groundfish trawlers and discarded due to low catch limits. Managers must account for the mortality of bycatch to assess population status accurately. Our objectives were to estimate the actual mortality of trawl-discarded lingcod (50- 84 cm) and describe...

Optical and hydrographic observations of the Cromwell Current between 92°00'W and the Galapagos Islands

Creator:: Zaneveld, J. Ronald, Pak, Hasong, and Plank, William S.
Abstract:: Optical and hydrographic observations were made at two meridional sections across the Cromwell Current at 92°00’ and 91°40’W during February 1969. The distribution of hydrographic and optical properties near the Galapagos Islands is described. Beneath the thermocline the Cromwell Current is characterized by deepening of the light-scattering isolines. Above the...

Initiation of the spring phytoplankton increase in the Antarctic Polar Front Zone at 170°W

Creator:: Landry, Michael R., Brown, Susan L., Selph, Karen E., Abbott, Mark R., Letelier, Ricardo M., Christensen, Stephanie, Bidigare, Robert R., and Casciotti, K.
Abstract:: During austral summer 1997, satellite imagery revealed enhanced chlorophyll associated with the Antarctic Polar Front at 170°W. Phytoplankton growth conditions during the early stages of the spring increase were investigated on the Antarctic Environment and Southern Ocean Process Study Survey I cruise using flow cytometry (FCM) and microscopy to characterize...
