Reducing the effects of fouling on chlorophyll estimates derived from long-term deployments of optical instruments

Creator:: Davis, R. F., Moore, C. C., Zaneveld, J. Ronald, and Napp, J. M.
Abstract:: Two methods to alleviate the problem of fouling of moored flow tube optical instruments are presented. A chemical method diffuses a concentrated solution of bromine into the flow tube between sampling periods, creating a toxic environment for microorganisms. An optical method removes a baseline value from the red peak of...

Eddy properties in the California Current System

Creator:: Kurian, Jaison, Colas, Francois, Capet, Xavier, McWilliams, James C., and Chelton, Dudley B.
Abstract:: Eddy detection and tracking algorithms are applied to both satellite altimetry and a high‐resolution (dx = 5 km) climatological model solution of the U.S. West Coast to study the properties of surface and undercurrent eddies in the California Current System. Eddy properties show remarkable similarity in space and time, and...

Altaf, Barr, Alan, Chen, Jing M., Davis, Kenneth J., Dimitrov, Dimitre, Hilton, Timothy W., Hollinger, David Y., Humphreys, Elyn, Poulter, Benjamin, Raczka, Brett M., Richardson, Andrew D., Sahoo, Alok, Thornton, Peter, Vargas, Rodrigo, Verbeeck, Hans, Anderson, Ryan, Baker, Ian, Black, T.

William, Oechel, Walter, Peng, Changhui, Price, David T., Ricciuto, Dan, Riley, William J., Roulet, Nigel, Tian, Hanqin, Tonitto, Christina, Torn, Margaret, Weng, Ensheng, and Zhou, Xiaolu
Abstract:: Accurately simulating gross primary productivity (GPP) in terrestrial ecosystem models is critical because errors in simulated GPP propagate through the model to introduce additional errors in simulated biomass and other fluxes. We evaluated simulated, daily average GPP from 26 models against estimated GPP at 39 eddy covariance flux tower sites...

Surface heat flux variability over the northern California shelf

Creator:: Beardsley, Robert C., Denver, Edward P., Lentz, Steven J., and Dean, Jerome P.
Abstract:: Surface heat flux components are estimated at a midshelf site over the northern California shelf using moored measurements from the 1981-1982 Coastal Ocean Dynamics Experiment (CODE) and the 1988-1989 Shelf Mixed Layer Experiment (SMILE). Time series of estimated fluxes extend from early winter through summer upwelling conditions, allowing examination 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...

Particle resuspension in the Columbia River plume near field

Creator:: Spahn, Emily Y., Homer-Devine, Alexander R., Nash, Jonathan, Jay, David A., and Kilcher, Levi
Abstract:: Measurements of suspended sediment concentration, velocity, salinity, and turbulent microscale shear in the near-field region of the Columbia River plume are used to investigate the mechanisms of sediment resuspension and entrainment into the plume. An east-west transect was occupied during spring and neap tide periods in August 2005 and May...

Local ocean response to a multiphase westerly wind burst 2. Thermal and freshwater responses

Creator:: Smyth, William D., Hebert, D., and Moum, James N.
Abstract:: A westerly wind burst observed in the warm pool of the western equatorial Pacific Ocean cooled the ocean's surface layer by about 0.8°C. Turbulent entrainment at the base of this layer caused cooling but also heating due to the reversal of the vertical temperature gradient during rain events. Consequently, the...

Interannual variability in phytoplankton pigment distribution during the spring transition along the west coast of North America

Creator:: Thomas, A. C. and Strub, P. Ted
Abstract:: A 5-year time series of coastal zone color scanner imagery (1980-1983, 1986) is used to examine changes in the large-scale pattern of chlorophyll pigment concentration coincident with the spring transition in winds and currents along the west coast of North America. The data show strong interannual variability in the timing...

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...

Creator:: Mote, Philip W. and Frey, Richard
Abstract:: This paper shows a small sampling of the atmospheric fields provided by the Moderate Resolution Imaging Spectroradiometer (MODIS), which is installed on both the Terra and Aqua satellites of the Earth Observing System. These fields include macroscale fields like cloud fraction, cloud top pressure, cloud optical depth, and column water...
