About the project
At global scale the OHC estimation is a very good proxy to monitor the EEI. The ESA MOHeaCAN project has successfully explored the feasibility to monitore the Global Ocean Heat Content from an Earth Observations (EO) based (altimetry – gravimetry) product. It was the first time that a global estimate of the OHC changes and the related changes in EEI from Spatial Observations has been made.
The objective of the 4DAtlantic-OHC project is focused on the Atlantic ocean and provides the opportunity to extend the MOHeaCAN’s work at regional scale where new challenges need to be taken up. Indeed, a series of processes and parameters (coastal area, mixed layer variability,...) that could be neglected at global scale cannot be neglected at regional scale anymore. Thus we need to explore the capability of EO missions and EO-based products in terms of space and time resolution to monitor the regional OHC in the Atlantic ocean. In addition, we need to develop a proper scheme to characterise and then propagate the uncertainty of the input measurements to derive reliable uncertainties of the final estimate of the regional OHC.
The 4DAtlantic-OHC objectives are:
