Tephra, all the explosive products of volcanic eruptions, is one of the primary hazards of volcanism. Despite being highly reactive, commonplace, and with evidence suggesting its deposition enhanced organic carbon burial in sediments, it is rarely considered in studies of the Earth System and the carbon cycle. In this talk I aim to discuss the processes by which tephra deposition effects marine carbon cycling and use a number of case studies from my own work to illustrate the impact of these mechanisms. These case studies cover a range of time periods, from the Ordovician to the present, and even into the future.
