Collaborative Research: Long-term Carbon Storage Shifts in High-latitude Peatlands with Paleoclimate Change: Linking Peatland Modeling with Paleoecology and Paleohydrology

Lead PI: Dr. Dorothy Peteet

Unit Affiliation: Biology and Paleo Environment, Lamont-Doherty Earth Observatory (LDEO)

North America ; Alaska
Project Type: Research

DESCRIPTION: The project proposes a data-model investigation of the relationship between paleoclimate and long-term carbon accumulation in Alaskan Arctic and subarctic peatland. Peat cores will be analyzed using compound-specific isotope and biomarker tracers as well as existing paleoclimate proxies and 14C dating.

OUTCOMES: Completed analyses of three sites and working on the fourth. Evidence shows that the peats experienced climatic shifts at similar times.
