River Rhône: Comprehensive French-Swiss project to remove tons of sediments

From 15 to 27 May 2025, a major cross-border operation between Switzerland (canton of Geneva) and France (department of Ain and Haut-Rhône) takes place: the river Rhône is emptied in order to remove 1.5 million cubic metres of accumulated sediment, particularly upstream of the Verbois dam.

Wie sich Südafrika aus dem Meer erhebt

Südafrika hebt sich langsam aus den Fluten – je nach Region um bis zu zwei Millimeter pro Jahr. Bislang glaubte man, dass Strömungsvorgänge im Erdmantel das Phänomen verursachen. Eine Studie der Universität Bonn liefert nun jedoch eine andere Erklärung: Demnach sind Dürren und die damit verbundenen Wasserverluste der Hauptgrund für den Anstieg.

Nor-Shipping 2025 turns spotlight on innovation

Nor-Shipping 2025, taking place in Oslo and Lillestrøm 2-6 June, announced on 12 May the shortlists for two of its most coveted accolades, the Next Generation Ship Award and the Ocean Solutions Award. Celebrating innovations, technologies and pioneering projects capable of balancing both environmental and commercial sustainability, the initiatives attracted a huge number of entries from across the world. Selecting the eventual winners was, according to Nor-Shipping Director Sidsel Norvik, „tougher than ever“.

University of Tübingen: Glyphosate in waters may originate from detergent additives

Certain detergent additives known as aminopolyphosphonates can be transformed into glyphosate and other problematic substances when wastewater is treated. A research team led by Professor Stefan Haderlein of the Geo- and Environmental Center at the University of Tübingen has made this fundamental finding. To achieve this, the team carried out comprehensive experiments in the laboratory which also included conditions found in wastewater. The finding solidifies the suspicion that detergent additives are a significant source of the consistently high levels of glyphosate in European waters. It was previously assumed glyphosate was released into the environment almost exclusively during its use as an herbicide. The study has been published in the scientific journal Nature Communications.

Auswirkungen des nächtlichen Himmelsleuchten

Lichtverschmutzung, die als Himmelsleuchten die Nacht erhellt, fördert das Wachstum von Cyanobakterien (gemeinhin auch Blaualgen genannt) und regt die Stoffumsätze in Seen an. Das zeigt eine aktuelle Studie des Leibniz-Instituts für Gewässerökologie und Binnenfischerei (IGB), die Teil des bislang größten Freilandexperiments zur Wirkung von Lichtverschmutzung auf Seen ist.
