Effects of stencil width on surface ocean geostrophic velocity and vorticity estimation from gridded satellite altimeter data

Creator:: Arbic, Brian K., Scott, Robert B., Chelton, Dudley B., Richman, James G., and Shriver, Jay F.
Abstract:: This paper examines the effect of “stencil width” on surface ocean geostrophic velocity and vorticity estimated from differentiating gridded satellite altimeter sea surface height products. In oceanographic applications, the value of the first derivative at a central grid point is generally obtained by differencing the sea surface heights at adjacent...

The role of turbulence stress divergence in decelerating a river plume

Creator:: Kilcher, Levi F., Nash, Jonathan D., and Moum, James N.
Abstract:: Turbulence controls the composition of river plumes through mixing and alters the plume's trajectory by diffusing its momentum. While believed to play a crucial role in decelerating river-source waters, the turbulence stress in a near-field river plume has not previously been observationally quantified. In this study, finely resolved density, velocity,...

Interannual variability of Great Lakes ice cover and its relationship to NAO and ENSO

Creator:: Bai, Xuezhi, Wang, Jia, Sellinger, Cynthia, Clites, Anne, and Assel, Raymond
Abstract:: The impacts of North Atlantic Oscillation (NAO) and El Niño–Southern Oscillation (ENSO) on Great Lakes ice cover were investigated using lake ice observations for winters 1963–2010 and National Centers for Environmental Prediction reanalysis data. It is found that both NAO and ENSO have impacts on Great Lakes ice cover. The...

Photosynthetic Characteristics and Estimated Growth Rates Indicate Grazing Is the Proximate Control of Primary Production in the Equatorial Pacific

Creator:: Cullen, John J., Lewis, Marlon R., Davis, Curtiss O., and Barber, Richard T.
Abstract:: Macronutrients persist in the surface layer of the equatorial Pacific Ocean because the production of phytoplankton is limited; the nature of this limitation has yet to be resolved. Measurements of photosynthesis as a function of irradiance (P-I) provide information on the control of primary productivity, a question of great biogeochemical...

Scales of variability of bio-optical properties as observed from near-surface drifters

Creator:: Abbott, Mark R., Brink, Kenneth H., Booth, C. R., Blasco, Dolors, Swenson, Mark S., Davis, Curtiss O., and Codispoti, L. A.
Abstract:: A drifter equipped with bio-optical sensors and an automated water sampler was deployed in the California Current as part of the coastal transition zone program to study the biological, chemical, and physical dynamics of the meandering filaments. During deployments in 1987 and 1988, measurements were made of fluorescence, downwelling irradiance,...

An assessment of phytoplankton primary productivity in the Arctic Ocean from satellite ocean color/in situ chlorophyll-a based models

Creator:: Lee, Younjoo J., Matrai, Patricia A., Friedrichs, Marjorie A. M., Saba, Vincent S., Antoine, David, Ardyna, Mathieu, Asanuma, Ichio, Babin, Marcel, Bélanger, Simon, Benoît‐Gagné, Maxime, Devred, Emmanuel, Fernández‐Méndez, Mar, Gentili, Bernard, Hirawake, Toru, Kang, Sung‐Ho, Kameda, Takahiko, Katlein, Christian, Lee, Sang H., Lee, Zhongping, Mélin, Frédéric, Scardi, Michele, Smyth, Tim J., Tang, Shilin, Turpie, Kevin R., Waters, Kirk J., and Westberry, Toby K.
Abstract:: We investigated 32 net primary productivity (NPP) models by assessing skills to reproduce integrated NPP in the Arctic Ocean. The models were provided with two sources each of surface chlorophyll-a concentration (chlorophyll), photosynthetically available radiation (PAR), sea surface temperature (SST), and mixed-layer depth (MLD). The models were most sensitive to...

An interlaboratory comparison of techniques for extracting and analyzing trapped gases in ice cores

Creator:: Sowers, Todd, Brook, Edward J., Etheridge, David, Blunier, Thomas, Fuchs, Andreas, Leuenberger, Markus, Chappellaz, Jerome, Barnola, Jean Marc, Wahlen, Martin, Deck, Bruce, and Weyhenmeyer, Connie
Abstract:: We undertook an interlaboratory comparison of techniques used to extract and analyze trapped gases in ice cores. The intercomparison included analyses of standard reference gases and samples of ice from the Greenland Ice Sheet Project 2 (GISP2) site. Concentrations of CO₂, CH₄, the δ¹⁸O of O₂, the δ¹⁵N of N₂,...

Biological production in the NE Pacific and its influence on air-sea CO2 flux: Evidence from dissolved oxygen isotopes and O2/Ar

Creator:: Juranek, L. W., Quay, P. D., Feely, R. A., Lockwood, D., Karl, D. M., and Church, M. J.
Abstract:: We determine rates of gross photosynthetic O₂ production (GOP) and net community O₂ production (NCP) using the triple oxygen isotope and O₂/Ar approach on two spring and two late summer meridional transects of the NE Pacific. Observed GOP and NCP in the subtropical (89 ± 9 and 8.3 ± 1.3...

Statistical properties of near surface currents in the California coastal transition zone

Creator:: Brink, K. H., Beardsley, R. C., Niiler, Pearn P., Abbott, Mark R., Huyer, Adriana, 1945-, Ramp, S., Stanton, T., and Stuart, D.
Abstract:: During the summers of 1987 and 1988, 77 near-surface satellite-tracked drifters were deployed in or near cold filaments near Point Arena, California (39ºN), and tracked for up to 6 months as part of the Coastal Transition Zone (CTZ) program. The drifters had large drogues centered at 15 m, and the...

Poleward propagating subinertial alongshore surface currents off the U.S. West Coast

Creator:: Kim, Sung Yong, Cornuelle, Bruce D., Terrill, Eric J., Jones, Burt, Washburn, Libe, Moline, Mark A., Paduan, Jeffrey D., Garfield, Newell, Largier, John L., Crawford, Greg, and Kosro, P. Michael
Abstract:: The network comprising 61 high-frequency radar systems along the U.S. West Coast (USWC) provides a unique, high resolution, and broad scale view of ocean surface circulation. Subinertial alongshore surface currents show poleward propagating signals with phase speeds of O(10) and O(100–300) km d⁻¹ that are consistent with historical in situ...
