Global distribution of production rates of radiolytic hydrogen and radiolytic oxidants in marine sediment; rates are expressed in mol electron equivalents/cm2/year; in electron equivalents, water radiolysis produces hydrogen and oxidized chemicals at equal rates; although abyssal clay has a volumetric radiolytic production rate an order of magnitude higher than the volumetric rate for continental-margin sediment types, the sediment layer that blankets open-ocean regions is much thinner and consequently has much lower vertically integrated radiolytic production than the sediment of continental margins.
