High Resolution Mapping of PO14C in the Northwest African Upwelling System Off Mauretania

Summary Here we report on the radiocarbon composition of particulate organic matter (POC) collected on four shelf (∼100 m water depth) to open ocean (∼2700 m water depth) transects in the northwest African upwelling system off Cape Blanc. Data show complex, seasonaly variable features of highly depleated POC in the water column sugguesting remobilization of pre-aged sediments.
