We inferred the population densities of blue whales (Balaenoptera musculus) and short-beaked
common dolphins (Delphinus delphis) in the Northeast Pacific Ocean as functions
of the water-column’s physical structure by implementing hierarchical models in a Bayesian
framework. This approach allowed us to propagate the uncertainty of the field observations
into the...

Using satellite sea surface height (SSH) and chlorophyll (CHL), the year 2000 is analyzed to characterize the effects of mesoscale circulation patterns on phytoplankton spatial variability in the California Current (CC) off Baja California. Satellite data are combined with and compared to in situ field measurements (chlorophyll-a and hydrographic variables)...
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 available for...
Mean fields, seasonal cycles, and interannual variability are examined for fields of
satellite-derived chlorophyll pigment concentrations (CHL), sea surface height (SSH), and
sea surface temperature (SST) during 1997–2002. The analyses help to identify three
dynamic regions: an upwelling zone next to the coast, the Ensenada Front in the north,
and...
