The latest news from Eawag

A new combination of data and statistical algorithms makes it possible for the first time to precisely track the movements of animals deep underwater.

The results have now been published in Science Advances.

Walter Giger was a pioneer in the life cycle analysis of environmental pollutants. He analysed, but also insisted that action be taken when the harmfulness of a substance was proven. His work on toxic nonylphenols attracted worldwide attention. Walter Giger passed away on 6 November 2025. With his passing, Eawag and environmental chemistry have lost an outstanding researcher, but for many he was also a good friend.
