Response to Comment on 'Dissolved organic sulfur in the ocean: Biogeochemistry of a petagram inventory'

摘要

Dittmar et al. proposed thatmixing alone can explain our observed decrease inmarine dissolved organic sulfur with age. However, their simple model lacks an explanation for the origin of sulfur-depleted organic matter in the deep ocean and cannot adequately reproduce our observed stoichiometric changes. Using radiocarbon age also implicitlymodels the preferential cycling of sulfur that they are disputing.
