ABSTRACT
This
paper presents a study of physical and biogeochemical variables using
numerical model and mixed layer oceanographic data from a 2 - 3 year in situmeasurements
in the Northwestern and Northeastern sites of the Atlantic Ocean. Model
outputs are presented and indicated that very good estimates may be
obtained. The outputs showed considerable agreement in reproducing
seasonal distributions of pCO2, pCO2-T, pCO2-nonT, mixed layer temperature, and chlorophyll-a in
both winter and summer, and therefore provide useful physical and
theoretical understanding of their biogeochemistry. The model pCO2indicated
a distinct temporal variability with seasonal changes coinciding with
the change in sea surface temperature. It also provides an agreement
that there is a strong seasonal cycle of mixed layer parameters filliped
by nonthermal and physical factors. As an outgrowth of this work, the pCO2 model outputs affirm the North Atlantic Ocean capacity as an important oceanographic sink for anthropogenic carbon dioxide.
