Persistent Shelf‐to‐Basin Export of Bioavailable Dissolved Organic Carbon in the Arctic Ocean

Microbial carbon demand often exceeds local primary production in the oligotrophic central Arctic Ocean. Whether shelf‐derived dissolved organic carbon (DOC) provides a persistent carbon subsidy to reconcile this imbalance remains unclear. Here, we combine amino acid‐based molecular tracers and hydrographic analyses to...
