To better understand the role of iron in driving marine ecosystems, the Southern Ocean Iron Experiment (SOFeX) fertilized two surface water patches with iron north and south of the Antarctic Polar Front Zone (APFZ). Using 1-D coupled biological–physical simulations, we examine the biogeochemical dynamics that occurred both inside and outside of the fertilized patches during and shortly after th...

stratiRed (vertical gradients of potential temperature, salinity and potential density, averaged horizontally or in time, are zero). The terminology is most precise in the case of a convectively forced boundary layer. Elsewhere, oceanographers use the term loosely to describe the region of the ocean that responds most directly to surface processes. Late in the day, following periods of strong h...

(2005) Mixed layer depth determination in the Barcelona costal area from regular lidar measurements: methods, results and limitations. Boundary-Layer Meteorology (in press) ABSTRACT Regular aerosol backscatter measurements using an elastic-backscatter lidar were performed understand the physical and chemical processes taking place in the low troposphere, was one of the major parameters to be re...

The barrier layer, the layer between the bottom of the density-defined mixed layer and the isothermal layer in the upper ocean, may play a role in air-sea dynamics. In the present study, data from Argo profiling floats in the tropical Indian Ocean and a mooring at 90 E, 0 N are used to examine subseasonal variations in upper ocean salinity and barrier-layer thickness (BLT) during boreal winter....

Basic entrainment equations applicable to the sheared convective boundary layer (CBL) are derived by assuming an inversion layer with a finite depth, i.e., the first-order jump model. Large-eddy simulation data are used to determine the constants involved in the parameterizations of the entrainment equations. Based on the integrated turbulent kinetic energy budget from surface to the top of the...

in this study variations of field data such as temperature, salinity and density in and across the transects of chahbahar bay were analyzed using ctd data acquired between winter 2006 and spring 2007 (winter monsoon).the results showed that thermocline layer intensify in mouth of bay between 2m and 6m with 7.81 ?c decrease before the gonou hurricane occured (mid-may 2007). below thermocline lay...

Mooring measurements at 0 ø, 165øE, for the period November 1988 to August 1991 indicate that surface layer structure was characterized by two distinct climatic regimes associated with dramatic differences in large-scale atmospheric and oceanic conditions. La Nifia conditions existed from November 1988 to November 1989, during which time the easterly trades were strong, Ekman divergence and upw...
