Dario Marconi

Dario Marconi is a Postdoctoral Research Fellow in the Sigman Research Laboratory at Princeton University, specializing in Geochemistry & Paleoclimate. His work focuses on nitrogen isotopes as tracers for oceanic nutrient cycling and climate reconstruction.

Research Interests:

• Marine nitrogen cycling and isotopic signatures
• Paleoclimate reconstruction via biogeochemical proxies
• Ocean circulation and nutrient transport dynamics
• Foraminifera-bound isotopes as ecological indicators
• Interactions between biological productivity and oxygen-deficient zones

Recent Publications highlight his expertise in isotopic analysis across the Pacific and Atlantic Oceans, with a focus on denitrification, nitrogen fixation, and nutrient recycling. Articles from 2024-2025 explore topics such as δ15N/δ18O nitrate isotopes, Agulhas Current dynamics, and photosymbiosis effects in foraminifera.
