Resumen:
Oceanographic data collected during 2001-2003
on the Patagonian Continental Shelf of Argentina were analyzed
in order to study the main chemical features of this large shelf.
The variation of inorganic nutrients and chlorophyll-a during
summer and fall in an area within 40 to 60 km from the coast
are presented. Nitrate is the limiting nutrient in the region and
is negatively correlated to chlorophyll-a. All variables show
localized variations in summer, which can be related to tidal
fronts through the comparison of our data with the critical
Simpson parameter of stability (50 J/m3). In fall, nutrient
concentrations on the continental shelf were more uniform and
generally higher than in summer due to the disruption of these
fronts.
