Microplastics (MPs) are distributed throughout the world oceans and represent one of the greatest environmental concerns of marine pollution. In the Gulf of Cadiz (GoC), MPs are found throughout the water column, on the seafloor, and accumulated within commercial marine species, primarily due to discharges from the main estuaries. The aim of this study was to analyse the transport pathways, spatial distribution, and accumulation regions of MPs in the GoC based on their density and source.

- The European sardine is a key fish species in the Western Iberia Upwelling Ecosystem, but its population has plummeted since the 2000s due to low recruitment rates.
- Research from 1998-2020 analyzed various environmental factors affecting sardine recruitment in two regions: NW Portugal and the Gulf of Cadiz.
- Key findings highlight that sea surface temperature significantly influences recruitment, with optimal conditions varying seasonally between regions, indicating the need for informed management to sustain sardine stocks amidst climate change.
The GoC shelf waters present much higher concentrations of dissolved Cu, Cd, and Zn than other coastal areas, constituting an important source of these elements onto its neighbouring basins, i.e., the Atlantic Ocean and the Mediterranean Sea.
