Abstract:
A series of discrete measurements were obtained on a near-monthly basis in a subtropical upwelling area of the Humboldt Current System during the year 2023. These included temperature, salinity, dissolved oxygen, fluorescence, and pH profiles, as well as measurements of zooplankton biomass and chlorophyll- and particulate organic carbon (POC) concentrations. The CTD information was analyzed through temporal section and S-T diagrams depicting the oxygen concentration. The measurements were conducted under distinct warm events associated with the ENSO dynamic. The objective of this study was to evaluate the influence of remote (ENSO) and upwelling forcing on the intraseasonal variability of zooplankton biomass.
