Carbon accumulation in Amazonian floodplain lakes: A significant component of Amazon budgets?
Abstract The Amazon floodplains cover approximately 10% of the Amazon Basin and are composed of predominantly anoxic sediments that may store large amounts of carbon. Our study combines 210 Pb derived sedimentation rates from four recently analyzed sediment cores ( n = 4) with previously published o...
