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
Commissions of the Danube River effective control of the Lower Danube in May 1939, when the Sinaia Agreement (concluded on 18 August 1938) entered into force. "See main articles Nazi rule over the Danube River (1938–1945) and Danube Commission (after 1945)" In 1938, a committee of experts inspected the Sulina and found it was almost impassable by that time. And in August of that same year, the regime of the two commissions was swept away by rise of German power on the river. A series of treaties put control in the hands of the Germans, who maintained it until the Nazi retreat in 1944 and
