Le projet 4DATLANTIC
On a global scale, the estimation of the Ocean Heat Content (OHC) is a very good indicator for monitoring the IEE (Earth Energy Imbalance). ESA’s MOHeaCAN project successfully explored the feasibility of monitoring the global ocean heat content from a product based on space-based geodetic observations (altimetry and gravity). This was the first time that a global estimate of OHC and related changes in the IEE from space-based observations was made.
The objective of the 4DAtlantic-OHC project is focused on the Atlantic Ocean and aims to extend the work carried out in the MOHeaCAN project to regional scales where new challenges related to geodetic data processing need to be addressed (coastal zone, taking into account salinity variations…).
Heat content of the Atlantic Ocean
The 4DAtlantic-OHC project is funded by the European Space Agency (ESA).

The objectives
• Estimating the ocean heat content (OHC) over the Atlantic Ocean using space geodetic data
• Conduct a scientific study to better understand the role of the Atlantic Ocean in the climate system
• Promote and transfer the results of the project to implement solutions for society
