The relationships between predatory fish, forage fishes, and juvenile salmonid marine survival off the Columbia River: a simple trophic model analysis

Creator:: Emmett, Robert L. and Sampson, David B.
Abstract:: A trophic model that simulates interactions between a predatory fish (Pacific hake, Merluccius productus), forage fish, and juvenile salmon off the Columbia River was constructed to identify if trophic interactions could account for marine mortality of Columbia River juvenile salmon. The model estimates the number of juvenile salmon that are...

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...

Seasonal presence of cetaceans and ambient noise levels in polar waters of the North Atlantic

Creator:: Klinck, Holger, Nieukirk, Sharon L., Mellinger, David K., Klinck, Karolin, Matsumoto, Haruyoshi, and Dziak, Robert P.
Abstract:: In 2009 two calibrated acoustic recorders were deployed in polar waters of the North Atlantic to study the seasonal occurrence of blue, fin, and sperm whales and to assess current ambient noise levels. Sounds from these cetaceans were recorded at both locations in most months of the year. During the...

Seafloor deformation and forecasts of the April 2011 eruption at Axial Seamount

Creator:: Chadwick, William W., Jr., Nooner, Scott L., Butterfield, David A., and Lilley, Marvin D.
Abstract:: Axial Seamount is an active submarine volcano located at the intersection between the Cobb hotspot and the Juan de Fuca spreading centre in the northeast Pacific Ocean1, 2. The volcano has been closely monitored since it erupted in 1998 (refs 3, 4). Since then, Axial Seamount seemed to exhibit a...

Sounds from airguns and fin whales recorded in the mid-Atlantic Ocean, 1999-2009

Creator:: Nieukirk, Sharon L., Mellinger, David K., Moore, Sue E., Klinck, Karolin, Dziak, Robert P., and Goslin, Jean
Abstract:: Between 1999 and 2009, autonomous hydrophones were deployed to monitor seismic activity from 16° N to 50° N along the Mid-Atlantic Ridge. These data were examined for airgun sounds produced during offshore surveys for oil and gas deposits, as well as the 20 Hz pulse sounds from fin whales, which may...

Estimating animal population density using passive acoustics

Creator:: Marques, Tiago A., Thomas, Len, Martin, Stephen W., Mellinger, David K., Ward, Jessica A., Moretti, David J., Harris, Danielle, and Tyack, Peter L.
Abstract:: conservation and ecology. Currently, the most widely used methods for obtaining such estimates involve either sighting animals from transect lines or some form of capture-recapture on marked or uniquely identifiable individuals. However, many species are difficult to sight, and cannot be easily marked or recaptured. Some of these species produce...

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...
