Black Sea biogeochemistry: Response to decadal atmospheric variability during 1960-2000 inferred from numerical modeling

► We model the Black Sea physical-biogeochemical structure using 1-D coupled model. ► We analysis the effect of long-term meteorological forcing on biogeochemistry variables in the Black Sea. ► Especially one such extreme event occurred in 1976 leading to a pronounced transition in oxygen and hydrogen sulfide state.
