Changes in the sea surface heights (SSH) and geostrophic currents along the eastern boundaries of the Pacific (North, Central and South America) are examined during the 1997–1998 El Niño using altimeter data and proxy winds. These show that 'symmetric' SSH signals left the equator and propagated into both Hemispheres in two episodes, with primary periods of(More)
Concurrent satellite-measured chlorophyll (CHL), sea surface temperature (SST), sea level anomaly (SLA) and model-derived wind vectors from the 13 þ year SeaWiFS period September 1997–December 2010 quantify time and space patterns of phytoplankton variability and its links to physical forcing in the Pacific Ocean. The CHL fields are a metric of biological(More)
Satellite surface height and temperature "elds are used to examine the seasonal surface circulation in the California Current System. In spring and summer, an equatorward jet develops next to the coast, with an initial latitudinal structure that responds to the latitudinal distribution of equatorward alongshore winds. This jet moves o!shore from spring to(More)
The seasonal variability of sea surface height (SSH) and currents are defined by analysis of altimeter data in the NE Pacific Ocean over the region from Central America to the Alaska Gyre. The results help to clarify questions about the timing of seasonal maxima in the boundary currents. As explained below, the long-term temporal mean of the SSH values must(More)
Changes in the sea surface heights (SSH) and geostrophic transports in the NE Pacific are examined during the 1997–1998 El Niño using altimeter data, sea level pressure (SLP) fields, proxy winds and satellite sea surface temperature (SST). Most of the signal occurs along the boundaries of the basin from Panama to the Alaska Peninsula. Changes in the SSH and(More)
[1] Satellite-derived data provide the temporal means and seasonal and nonseasonal variability of four physical and biological parameters off Oregon and Washington (41°–48.5°N). Eight years of data (1998–2005) are available for surface chlorophyll concentrations, sea surface temperature (SST), and sea surface height, while six years of data (2000–2005) are(More)
Satellite-derived sea surface salinity (SSS) data from Aquarius and SMOS are used to study the shelf-open ocean exchanges in the western South Atlantic near 35 S. Away from the tropics, these exchanges cause the largest SSS variability throughout the South Atlantic. The data reveal a well-defined seasonal pattern of SSS during the analyzed period and of the(More)
A high-resolution model is used to characterize the dominant patterns of sea surface salinity (SSS) variability generated by the freshwater discharges of the Rio de la Plata (RdlP) and the Patos/Mirim Lagoon in the southwestern Atlantic region. We identify three dominant modes of SSS variability. The first two, which have been discussed in previous studies,(More)
Explanation The main text of the paper presents fields for selected months (January, April, July and October) to represent the seasonal cycles of surface wind stress forcing and the ocean's response over the shelf in the SW Atlantic Ocean. Here we present the fields for the 12-year means of all 12 calendar months for four parameters: (1) surface wind(More)
