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...

A comparison of mechanisms generating vertical transport in the Brazilian coastal upwelling regions

Creator:: Mazzini, P. L. F. and Barth, John A.
Abstract:: Several mechanisms can drive vertical velocities in the coastal ocean, including wind-forcing and through gradients in the vorticity field generated by flow-topography interactions. A two-layer, steady, wind-driven, analytical model is applied to the major upwelling systems of Brazil : Cabo Frio (CF) and Cabo de Santa Marta (CSM) regions. Comparisons...

Structure of the coastal current field off Northern California during the coastal ocean dynamics experiment

Creator:: Kosro, P. Michael, 1951-
Abstract:: For 74 days during the spring and summer upwelling seasons of 1981 and 1982, in conjunction with the Coastal Ocean Dynamics Experiment, profiles of upper ocean currents were collected in the waters over the shelf and slope off northern California using a shipboard Doppler acoustic log. These measurements provide detailed...

Evaluation of directly wind-coherent near-inertial surface currents off Oregon using a statistical parameterization and analytical and numerical models

Creator:: Kim, Sung Yong, Kosro, P. Michael, and Kurapov, Alexander L.
Abstract:: Directly wind-coherent near-inertial surface currents off the Oregon coast are investigated with a statistical parameterization of observations and outputs of a regional numerical ocean model and three one-dimensional analytical models including the slab layer, Ekman, and near-surface averaged Ekman models. The transfer functions and response functions, statistically estimated from observed...

Influence of varying upper ocean stratification on coastal near-inertial currents

Creator:: Kim, Sung Yong, Kurapov, Alexander L., and Kosro, P. Michael
Abstract:: The influence of varying horizontal and vertical stratification in the upper layer ( inline image m) associated with riverine waters and seasonal atmospheric fluxes on coastal near-inertial currents is investigated with remotely sensed and in situ observations of surface and subsurface currents and realistic numerical model outputs off the coast...

A two-way nested simulation of the oceanic circulation in the Southwestern Atlantic

Creator:: Combes, Vincent and Matano, Ricardo P.
Abstract:: This article presents the results of a high-resolution (1/12°), two-way nested simulation of the oceanic circulation in the southwestern Atlantic region. A comparison between the model results and extant observations indicates that the nested model has skill in reproducing the best-known aspects of the regional circulation, e.g., the volume transport...

Atmospheric conditions during the spring and fall transitions in the coastal ocean off western United States

Creator:: Strub, P. Ted and James, Corinne
Abstract:: We examine large-scale atmospheric behavior around the time of the spring and fall transitions in the coastal ocean off the west coast of North America. Records of adjusted sea level (ASL), coastal wind stress, sea level atmospheric pressure (SLP), and 500-mbar heights for the years 1971-1975 and 1980-1983 are analyzed....

Satellite observations of chlorophyll, phytoplankton biomass, and Ekman pumping in nonlinear mesoscale eddies

Creator:: Gaube, P., Chelton, D. B., Strutton, P. G., and Behrenfeld, Michael J.
Abstract:: Nonlinear mesoscale eddies can influence biogeochemical cycles in the upper ocean through vertical and horizontal advection of nutrients and marine organisms. The relative importance of these two processes depends on the polarity of an eddy (cyclones versus anticyclones) and the initial biological conditions of the fluid trapped in the core...

Chlorophyll enchancement and mixing associated with meanders of the shelf break front in the Mid-Atlantic Bight

Creator:: Ryan, J. P., Yoder, J. A., Barth, John A., and Cornillon, P. C.
Abstract:: Meanders of the shelf break front in the Mid-Atlantic Bight (MAB) during April and May of 1997 were associated with chlorophyll enhancement along a hydrographic and a topographic feature. The hydrographic feature was the surface outcrop of the front, which ranged from ~10 to >100 km seaward of the shelf...

The structure of the transition zone between coastal waters and the open ocean off northern California, winter and spring 1987

Creator:: Kosro, P. Michael, 1951-, Huyer, Adriana, 1945-, Ramp, S. R., Smith, Robert L. (Robert Lloyd), 1935-, Chavez, F. P., Cowles, Timothy J., Abbott, Mark R., Strub, P. Ted, Barber, R. T., Jessen, P., and Small, Lawrence F.
Abstract:: Physical and biological fields in the coastal transition zone off northern California were measured during February, March, May and June 1987 in an extended alongshore region between 60 km and 150 km offshore. The spring transition, as seen in coastal sea level and winds, occurred in mid-March. Surface variability during...
