Seasonal sampling targets phytoplankton, zooplankton, benthic organisms, habitats, and hazardous substances to support ecosystem assessment. Sampling is stratified over depth (0-90 m) and season, including CTD profiling and sediment analysis. The program informs biogeochemical dynamics and biodiversity trends in a semi-enclosed coastal system heavily influenced by urban and industrial inputs.
