Seqestration of dissolved organic carbon in the deep sea

Abstract

We used compound specific natural abundance radiocarbon analyses of neutral sugars to study carbon cycling of high molecular weight (HMW) dissolved organic carbon (DOC) at two sites in the North Pacific Ocean. Sugars released from HMWDOC by acid hydrolysis were purified by high-pressure liquid chromatography and analyzed for radiocarbon content via accelerator mass spectrometry. We find the seven most
