Danube-Gunz interglacial age of about 900,000 to 940,000 years. There are however indications that the Uhlenberg Profile may still be placed within the Pliocene, and it would thus not correlate with the Danube-Gunz interglacial. Also uncertain is its association with the North German classification because of its position in the underlying stratum of the Gunz it could correspond to the Bavelian or the Waalian interglacial. The Danube-Gunz corresponds at least in part to the Swiss Deckenschotter glaciations. Danube-Gunz interglacial The Danube-Gunz interglacial (), Danube-Gunz warm period ("Donau-Günz-Warmzeit"), often just Danube-Gunz, or also Uhlenberg interglacial ("Uhlenberg-Warmzeit") is the second-oldest named warm period of
International Commission for the Protection of the Danube River and the ground water resources. The ICPDR’ legal basis is the “Convention on Cooperation for the Protection and Sustainable use of the Danube River (Danube River Protection Convention)”, generally referred to as the “Danube River Protection Convention” or “DRPC”. It commits the contracting parties to join their efforts in sustainable water management, including conservation of surface and ground water, pollution reduction, and the prevention and control of floods, accidents and ice hazards. The convention was signed in Sofia, Bulgaria, in 1994 and came into force in October 1998. The ICPDR was created to implement the Danube River Protection Convention (DRPC).
