NOAA’s role in constraining the ocean carbon sink

Simone R. Alin, Bianca C. Baier, Brendan R. Carter, Tim DeVries et autres

NOAA is a global leader in observing, modeling, and understanding the ocean’s critical role in absorbing atmospheric CO2. This observational and modeling expertise provides a vital foundation for understanding the global carbon cycle and informing possible mitigation strategies.

Reconstruction and Multiyear Prediction of Global Air-sea CO2 Flux using NOAA GFDL's SPEAR Ensemble

A Global Perspective on River Alkalinity: Drivers and Implications for Coastal Ocean Carbonate Chemistry

Fei Da, Charles A. Stock, John P. Dunne, Xiao Liu et autres

Abstract The chemical nature of river water significantly influences the coastal carbonate system, contributing to coastal acidification and creating suboptimal conditions for marine calcifiers. While several regional efforts have assessed observationally based riverine concentrations and fluxes of total alkalinity (TA) and dissolved …

Photoacclimation and Photoadaptation Sensitivity in a Global Ocean Ecosystem Model

Charles A. Stock, John P. Dunne, Jessica Y. Luo, Andrew Ross et autres

Abstract Chlorophyll underpins ocean productivity yet simulating chlorophyll across biomes, seasons and depths remains challenging for earth system models. Inconsistencies are often attributed to misrepresentation of the myriad nutrient supply, growth and loss processes that govern phytoplankton biomass. They may also arise, …

Simulating Argo float trajectories and along-track physical and biogeochemical variability in the California Current System

Xiao Liu, John P. Dunne, Elizabeth J. Drenkard, Gregory C. Johnson

Trajectories of >1,600 virtual Argo profiling floats and their sampled variability in key ocean physical and biogeochemical variables are simulated using a 0.125° global ocean physical-biogeochemical model (NOAA GFDL’s MOM6-SIS2-COBALTv2) and an offline Lagrangian particle tracking algorithm. Virtual floats are deployed at …

Assessing the Effectiveness of Ocean Iron Fertilization for the Carbon-Uptake Efficacy

Kyung Min Noh, Xiao Liu, Charles A. Stock, John P. Dunne

Rapidly increasing carbon dioxide emissions over the past decades and the possibility of further increases in coming decades has motivated global efforts to remove and sequester carbon from atmosphere. Among recent proposals for marine-based Carbon Dioxide Removal (mCDR), ocean iron-fertilization has been …

Detecting, Attributing, and Projecting Global Marine Ecosystem and Fisheries Change: FishMIP 2.0

Julia L. Blanchard, Camilla Novaglio, Olivier Maury, Cheryl S. Harrison et autres

Abstract There is an urgent need for models that can robustly detect past and project future ecosystem changes and risks to the services that they provide to people. The Fisheries and Marine Ecosystem Model Intercomparison Project (FishMIP) was established to develop model …

Characterizing Subsurface Oxygen Variability in the California Current System (CCS) and Its Links to Water Mass Distribution

Cristina Schultz, John P. Dunne, Xiao Liu, Elizabeth J. Drenkard et autres

Abstract The california current system (CCS) supports a wide array of ecosystem services with hypoxia historically occurring in near‐bottom waters. Limited open ocean data coverage hinders the mechanistic understanding of CCS oxygen variability. By comparing three different models with varying horizontal resolutions, …
