Multiscale observing system simulation experiments for iron fertilization in the Southern Ocean, Equatorial Pacific, and Northeast Pacific

PI: Dennis McGillicuddy, Woods Hole Oceanographic Institute
Start Year: 2023 | Duration: 3 years
Partners: Woods Hole Oceanographic Institution, National Center for Atmospheric Research, NOAA Geophysical Fluid Dynamics Laboratory

Project Abstract:

This project studies the effectiveness of iron enrichment for carbon capture at different scales and the long-term effects of regional iron fertilization. Researchers will use Observing System Simulation Experiments run by ocean biogeochemical models to assess the potential impacts of new observing systems, instrumentation, or data assimilation, prior to implementation. The Observing System Simulation Experiments will target field trials in three regions: the Southern Ocean, the Equatorial Pacific, and the Subarctic Pacific. High resolution models will examine the extent of carbon sequestration and potential effects on local and remote ecosystems on a small scale. Global biogeochemical models will explore the long-term effects of regional iron fertilization, including carbon sequestration and monitoring of ecosystem perturbations.
