Location: Upstream Iller, Germany
Today, the JDS2 International Team began work at the first of the 97 sampling sites. The first site, at the river kilometer 2600 (from where the Danube meets its Delta), is situated upstream of the Iller River. As the route was not navigable for the Argus ship, cars took the scientists to the site and back, three hours each way. The experts worked on macrophytes, benthic invertebrates, phytobenthos, phytoplankton, microbiology and water chemistry.
