This study presents the first direct proxy for reconstructing past marine dissolved organic carbon (DOC) using organic carbon co-precipitated in iron ooids. Applied to 26 formations spanning 1,650 million years, the results reveal major DOC fluctuations linked to ocean oxygenation and biological evolution, highlighting connections between the carbon cycle, ecosystem structure, and the rise of complex life.

Abstract
This study presents the first direct proxy for reconstructing past marine dissolved organic carbon (DOC) using organic carbon co-precipitated in iron ooids. Applied to 26 formations spanning 1,650 million years, the results reveal major DOC fluctuations linked to ocean oxygenation and biological evolution, highlighting connections between the carbon cycle, ecosystem structure, and the rise of complex life.File in questo prodotto:
