Abstract Reservoirs act as carbon sinks when sedimentation of particulate organic (POC) exceeds CO 2 and CH 4 emissions. Here, we study the poorly explored process where phytoplankton‐derived acidic polysaccharides (APs) aggregate into matter, promoting export to sediments. This source POC in sediments can mineralize over various timescales. Our research, centered on a Mediterranean reservoir, elucidates phenological trends APs identifies their predominant drivers. findings present synchronic patterns but identify 2‐week delay between Despite its eutrophic status, our data demonstrate this reservoir's role sink, sequestering 4.33 g C m −2 yr −1 . highlights need consider time scales quantifying budgets reservoirs.
