  abstract = {{M}arinas are semi-enclosed environments characterised by reduced hydrodynamic energy, high sedimentation rates, and reduced oxygen levels. {T}he ongoing development of activities and infrastructure construction are leading to deterioration in the quality of coastal aquatic environments, creating environmental risks. {T}race metal elements ({TME}s) and organotins are significant contaminants, prompting this study to evaluate the added value of spatiotemporal monitoring compared to one-time sediment assessments. {T}wo {M}editerranean harbours, {P}ort {C}amargue ({PC}) and {P}ort {C}arnon ({C}), differing in morphology and size, were monitored for a year with regular water sampling, focusing on {TME}s and organotins. {S}ediment contamination, notably in the technical zone, revealed concentrations of {C}u (309 and 1210 mg kg-1 for {C} and {PC}, respectively), {Z}n (242 and 425 mg kg-1 for {C} and {PC}, respectively), and tributyltin ({TBT}) (198 and 4678 mu g ({S}n) kg-1 for {C} and {PC}, respectively) surpassing the effect range medium ({ERM}), while other marina stations generally stayed below this threshold. {S}patiotemporal water monitoring highlighted concentrations above environmental quality standards ({EQS}) at all stations of the larger marina. {T}his exceedance was systematic for {C}u and {Z}n in all samples, ranging respectively between 2.54 and 37.56 mu g ({S}n) {L}-1 and 0.63 and 33.48 mu g ({S}n) {L}-1. {A} notable temporal dynamic for {TBT} and {C}u was also observed. {C}onversely, the open marina, connected to the open sea, rarely exhibited concentrations above {EQS} in water, despite sediment concentrations occasionally exceeding {ERM} values. {T}his underscores that risk assessment in these ecosystems cannot rely solely on sediment characterisation.},
