Short summary
Significantly high total hydrolysable amino acid concentrations and yields were observed in the East/Japan Sea of deep-water formation, indicating the convection of margin-derived bioavailable dissolved organic matter to deep waters. Our observational results suggest that the effective transport of bioavailable DOM to the deep ocean can be significantly sensitive to changes in the deep-water renewal rates and in temperature of the surface ocean, linked to global warming.
