Distributions of temperature, salinity, and barium in near-surface waters (depth ≤ 50 m) of the Laptev Sea and adjacent areas of the Arctic Ocean are presented for the summers of 1993, 1995, and 1996. The tracer data indicate that while fluvial discharge was largely confined to the shelf region of...
A numerical model has been used to investigate the wind-driven circulation in a stratified basin of
moderate size, Lake Tahoe, California-Nevada. Two types of circulation are identified: "direct" circulations,
in which the current directions remain relatively constant and the mean circulation formed over
several days resembles the instantaneous circulation, and...
Across-shelf transects over the eastern flank of Barrow Canyon were obtained in August 2005 with an autonomous underwater vehicle (AUV). Here, the shelf topography creates a “choke” point in which a substantial portion of Pacific inflow from the Bering Strait is concentrated within 30 km of the coast, providing an...
The Chukchi Sea is thought to be a globally important sink of atmospheric CO₂ due to the summertime drawdown of surface pCO₂ by phytoplankton and subsequent shelf-to-basin transport of CO₂-enriched subsurface waters into the upper halocline of the Arctic Ocean. Here we show that annually occurring storm-induced mixing events during...
Velocity measurements from 17 deployments of moored acoustic Doppler current
profilers obtained during four summer upwelling seasons are used to describe the crossshelf
divergence of Ekman transport in the inner shelf off Oregon. For each deployment
the measured surface and bottom cross-shelf transports were compared with estimates
of the theoretical...
The surface wind and stress responses to sea surface temperature (SST) are examined using collocated moored buoy and satellite observations in the Gulf Stream and the eastern equatorial Pacific. Using 17 buoy pairs, differences in the wind speed, 10-m equivalent neutral wind speed (ENW), and surface wind stress magnitude between...
Introduction: Biotic soil crust communities contribute valuable ecosystem services and biodiversity in steppe ecosystems. The uncommon crust lichens Acarospora schleicheri, Fuscopannaria cyanolepra, Rhizocarpon diploschistidina, and Texosporium sancti-jacobi are associated with fine-textured soils along rivers of the Columbia Basin. A. schleicheri and R. diploschistidina indicate late-successional habitat and may serve as...
The authors investigate atmospheric internal gravity waves (IGWs): their generation and induction of global intermittent turbulence in the nocturnal stable atmospheric boundary layer based on the new concept of turbulence generation discussed in a prior paper by Sun et al. The IGWs are generated by air lifted by convergence forced...
Regulatory requirements and shifts in consumer preferences have resulted in seafood products bearing multiple information labels. Developing successful seafood marketing strategies requires an understanding of how multilabeled products influence consumer choices. This paper analyzes preferences for four classes of seafood information labels including safety, quality, local, and ecolabels using data...
Since September 2006, the Oregon State University (OSU) Archives has concentrated on the preparation of collection-level finding aids for all new collections received by the Archives and for collections that have no descriptive information available online. This article presents a preliminary analysis of the results of this approach, demonstrates the...
