The penetration of anthropogenic transient tracers, such as chlorofluorocarbons (CFCs) and sulfur-hexafluoride (SF6), into the oceans represents an opportunity to trace intermediate-to-abyssal water masses as they leave the surface mixed layer and estimate the ventilation rate of the global ocean since 1940. I will present analyses based on four decades of CFCs and SF6 observations to reconstruct global tracer budgets and infer decadal variability of deep ocean circulation and tracer ventilation rates.
