To establish foundational ground rules for using marine cerium anomalies as reliable proxies for past oceanic redox states and widespread anoxia.
Analyzed contemporary rare earth element distribution patterns and geochemical cycling in modern marine environments.
Evaluated the validity and methodological consistency of published paleoceanographic studies applying cerium anomalies as paleoredox proxies.
Modern marine distributions reveal that local oceanographic processes and phase associations heavily influence cerium behavior, complicating direct redox interpretations.
Identified critical interpretive limitations in existing literature where sedimentary cerium anomalies were applied without accounting for baseline marine rare earth element dynamics.
