Wind-driven inner-shelf circulation off central Oregon during summer

Creator:: Kirincich, Anthony R., Barth, John A., Grantham, Brian A., Menge, Bruce A., and Lubchenco, Jane
Abstract:: 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...

Aerosol particles collected on aircraft flights over the northwestern Pacific region during the ACE-Asia campaign: Composition and major sources of the organic compounds

Creator:: Simoneit, Bernd R. T., Kobayashi, Minoru, Mochida, Michihiro, Kawamura, Kimitaka, and Huebert, Barry J.
Abstract:: Atmospheric particulate matter, collected over the polluted east Asia/Pacific region in spring 2001 during research flights with the National Center for Atmospheric Research (NCAR) C-130 aircraft, was analyzed for different types of organic compounds using capillary gas chromatography–mass spectrometry. More than 70 organic species were detected in the aerosols and...

Alongshore currents and mesoscale variability near the shelf edge off northwestern Australia

Creator:: Brink, K. H., Bahr, Frank, and Shearman, R. Kipp
Abstract:: Shelf break conditions and alongshore flow off northwestern Australia are studied during the strongly evaporative conditions of austral winter 2003. Present results, along with those of previous authors, confirm that a poleward, fresh Leeuwin current core is normally found near the shelf break. Salinity increases alongshore toward the southwest. Although...

Diffuse attenuation coefficient of downwelling irradiance: An evaluation of remote sensing methods.pdf

Creator:: Lee, Zhong-Ping, Darecki, Miroslaw, Carder, Kendall L., Davis, Curtiss O., Stramski, Dariusz, and Rhea, W. Joseph
Abstract:: The propagation of downwelling irradiance at wavelength l from surface to a depth (z) in the ocean is governed by the diffuse attenuation coefficient, K𝒹(λ). There are two standard methods for the derivation of K𝒹(λ) in remote sensing, which both are based on empirical relationships involving the blue-to-green ratio of...

Uncertainties in, and interpretation of, carbon flux estimates using the eddy covariance technique

Creator:: Loescher, H. W., Law, B. E., Mahrt, Larry, Hollinger, D. Y., Campbell, J., and Wofsy, S. C.
Abstract:: Whole ecosystem carbon dioxide (CO₂) exchange estimated with the eddy covariance (EC) technique has been central to studies on the responses of terrestrial ecosystems to disturbance and intra‐annual and interannual variations in climate, but challenges exist in understanding and reducing the uncertainty in estimates of net ecosystem exchange (NEE) of...

Spatial and interannual variability in mesoscale circulation in the northern California Current System

Creator:: Keister, Julie Eileen and Strub, P. Ted
Abstract:: We used wavelet analyses of sea surface height (SSH) from >13 years of satellite altimeter data to characterize the variability in mesoscale circulation in the northern California Current (35°N–49°N) and explore the mechanisms of variability. We defined ‘‘mesoscale’’ circulation as features, such as eddies and filaments, which have 50- to...

Spectral analysis of seismic noise induced by rivers: a new tool to monitor spatiotemporal changes in stream hydrodynamics

Creator:: Burtin, A., Bollinger, L., Vergne, J., Cattin, R., and Nabelek, John L.
Abstract:: Analysis of continuous seismic data recorded by a dense passive seismological network (Hi‐CLIMB) installed across the Himalayas reveals strong spatial and temporal variations in the ambient seismic energy produced at high frequencies (>1 Hz). From June to September 2003, the high‐frequency seismic noise is observed to increase up to 20...

Horizontal wave number spectra of temperature in the unstably stratified oceanic surface layer

Creator:: Wijesekera, Hemantha W., Paulson, Clayton A., and Huyer, Adriana, 1945-
Abstract:: Horizontal wave number spectra of temperature in the unstably stratified oceanic surface layer were determined from measurements on a bow boom at a depth of 2 m. Spectra were estimated in the wavelength band from 2 m to 2 km, normalized in accordance with Monin-Obukhov similarity theory, and averaged in...

Wind-driven transport pathways for Eurasian Arctic river discharge

Creator:: Guay, Christopher K. H., Falkner, Kelly, Muench, Robin D., Mensch, Manfred, Frank, Markus, and Bayer, Reinhold
Abstract:: 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...

Kelvin wave signatures in stratospheric trace constituents

Creator:: Mote, Philip W. and Dunkerton, Timothy J.
Abstract:: Connections, sometimes tenuous, have previously been noted between stratospheric Kelvin waves and several stratospheric trace constituents. The present study finds evidence of Kelvin wave signatures in ozone from the Microwave Limb Sounder (MLS) and Cryogenic Limb Array Etalon Spectrometer (CLAES) instruments aboard the Upper Atmosphere Research Satellite. Predominant variations near...
