Editing Carbon Uptake Flux (Ocean) (section)

== Monitoring and Measurement ==
Oceanic carbon uptake is monitored using a combination of observational and modeling approaches. Direct measurements include surface ocean CO2 partial pressure (pCO2) obtained from research vessels, autonomous floats, and moored buoys. Remote sensing technologies provide complementary data on [https://en.wikipedia.org/wiki/Sea_surface_temperature sea surface temperature] and chlorophyll concentrations, which relate to biological activity influencing carbon uptake. Additionally, global carbon cycle models assimilate observational data to estimate fluxes at various spatial and temporal scales. Institutions involved in monitoring include national oceanographic agencies and international programs dedicated to carbon cycle research.

Within the SIGNAL system, this phenomenon is treated as a defined environmental signal whose boundaries and measurement conventions are described below.
