The Joint Danube Survey 5 (JDS5), the world’s most comprehensive investigative surface-water monitoring effort, will officially kick off on 1 July 2025 in Vienna. This large-scale scientific survey will bring together experts from 14 countries to assess the health of the Danube River and its major tributaries.

The JDS 5 survey will be realized during 2025, under the coordination of the International Commission for the Protection of the Danube River (ICPDR), in cooperation with the Danube countries and with the support of the European Commission.

The IBISS researchers are involved in this important international expedition for the fifth time and have been actively participating in the implementation of biological and other research programs since 2001.
