Trends in satellite-based observations of the ocean carbon cycle (Gemma Kulk)
Using SCOPE’s harmonised, climate quality dataset of carbon pools and fluxes, long term trends since 1997 were assessed to understand how marine carbon uptake and ecosystem processes are changing under climate pressure.
Integrating Satellite-Observed Surface Carbon into Ocean Biogeochemical Model to Improve Ocean Carbon Cycle (Valentina Sicardi)
SCOPE’s satellite derived phytoplankton carbon (Cphy) data were successfully assimilated into the EC-Earth biogeochemical model, improving estimates of primary production, export flux, and air–sea CO₂ exchange. Especially in remote and poorly sampled regions.
A satellite-based estimates of biological pools and fluxes of carbon in the oceanic mixed layer (Shubha Sathyendranath)
Advances in satellite carbon algorithms and OC-CCI timeseries enabled improved estimates of primary production, particulate and dissolved carbon, and export fluxes across the ocean’s mixed layer, enhancing consistency across biological carbon datasets.

Coupling Biological and Microbial Carbon Pumps in the North Atlantic Subtropical Gyre (Mengyu Li)
By combining satellite products, BGC Argo data, and 4D reconstructions, the team revealed new insights into how particle export and microbial processing interact in the North Atlantic Subtropical Gyre, including a measurable time lag between the two carbon pumps.
Together, these results highlight the project’s growing impact in reducing uncertainties, improving climate relevant assessments, and strengthening the evidence base needed to guide future carbon research and decision-making.
