Intermediate water circulation is a key player in global ocean circulation and contributes to the variability of the Atlantic Meridional Overturning Circulation (AMOC) which plays a fundamental role in climate regulation. However, the ocean dynamics at intermediate depths since the Last Glacial Maxi...
