We adapted the Tea Bag Index (TBI), a highly standardized methodology for determining soil decomposition, for lakes by incorporating a leaching factor. A Citizen Science project was organized to test the aquatic TBI in 40 European lakes located in four climate zones, ranging from oligotrophic to hypereutrophic systems. The overall high decomposition rates found confirm the active role lakes play in the global carbon cycle. The lakes in the warmer temperate zone displayed a higher decomposition rate compared to the colder lakes in the continental and polar zones. Decomposition rates were also higher in eutrophic lakes compared to oligotrophic lakes. Additionally, the eutrophic lakes showed a higher stabilization factor (S), thus a less efficient microbial community, compared to the oligotrophic lakes. Our results show that the TBI can be used to adequately assess the decomposition process in aquatic systems. By providing scholarly support to the citizen groups we also showed that collecting scientifically relevant data can go hand in hand with increasing scientific and environmental literacy in participants.
