Total organic carbon, organic phosphorus, and biogenic barium fluxes as proxies for paleomarine productivity
Although marine productivity is a key parameter in the global carbon cycle, reliable
estimation of productivity in ancient marine systems has proven difficult. In this study, we …

A critical look at iron paleoredox proxies: New insights from modern euxinic marine basins
TW Lyons, S Severmann - Geochimica et Cosmochimica Acta, 2006 - Elsevier
Enrichments in reactive iron occur under euxinic marine conditions, that is, where dissolved
