13 pages. -- File includes: Supplementary Text, Supplementary Figures and tables. -- Figure SI1. Illustrations by dbRDA of the relationships between the predictors modelled and the concentration of microplastics from the DistLM analysis of all sampling stations (n = 28) (the best model, see table 1). -- Figure SI2 SEM image (left) and Optic Microscopy image (right) of two stations sampled. -- Figure SI3. FTIR spectra of microplastic collected from the Gulf of Cadiz. FTIR spectra contain a mixture of all these plastics . -- Figure SI4. Rainfall and Dam freshwater discharge in the Guadalquivir estuary: Average monthly rainfall and dam discharges between March and June from 1997 to 2018. -- Figure SI5. The currents at the near‐surface level (cm/s) superimposed with sea surface temperature (SST in the rage 17-20ºC) and chlorophyll concentration (Chl-a, in the range 0-3.2 mg / m3) for 15th June 2019. -- Table SI1. Dataset with station name, concentration of microplastic, temperature (ºC), salinity, chlorophyll a fluorescence (mg m-3), oxygen (mg L-1), longitude and latitude in June 2019 between the days 14 and 19. -- Table SI2. Test statistics for the Distance-based Linear Model (DISTLM) analyses of the marginal and sequential tests based on ‘Step-wise’ procedure and AICc criteria of the microplastics at the 28 sites sampled. -- Table SI3. Information collected about MP surveys in environmental marine environments.
