Dissolved Organic Carbon (C13 and C14) Measurements, Beaufort Sea, 2009, CCGS Amundsen
Dissolved organic carbon (DOC) in the ocean is thousands of 14C years old, yet a portion of the DOC cycles on much shorter time scales (days to decades). We present 14C measurements of DOC in the Arctic Ocean and estimate that ≥8% of the DOC in the deep Eurasian basin contains bomb 14C. While this i...

Dissolved organic carbon (DOC) in the ocean is thousands of 14C years old, yet a portion of the DOC cycles on much shorter time scales (days to decades).
