To establish effective water quality monitoring strategies in estuaries, it is imperative to identify and understand the main drivers for the variation of water quality parameters. The tidal effect is an important factor of the daily and fortnightly variability in several estuaries. However, the extent of that influence on the different physicochemical and biological parameters is still overlooked in some estuarine systems, such as the Sado Estuary, a mesotidal estuary located on the west coast of Portugal.

- Primary productivity in oceans is more stable far from coasts, but can vary greatly near shores, leading to abnormal phytoplankton blooms, like the significant one off the Western Iberian Coast in March 2009.
- This bloom was notable for its large biomass and represented one of the largest blooms relative to regional norms, influenced by both long-term (like deep winter mixed layer depths) and short-term factors (such as coastal upwelling).
- The impact of such blooms on the ecosystem is hard to measure, but they may become more frequent due to climate change, potentially affecting carbon export and marine food webs, making this research vital for monitoring coastal regions and fisheries.
