An international research team from the Alfred Wegener Institute (AWI) is investigating the causes and interactions of melting sea ice in the Arctic Ocean on board the research icebreaker "Polarstern". The Polarstern set off from Tromsø, Norway, on 2 July 2025 to spend the next two months analysing feedbacks between global warming and sea-ice retreat in the Arctic Ocean. The investigations will focus on the differences in the melting of different types of sea ice, which represent past, present and future Arctic sea ice. One-year-old sea ice, which formed last winter, often drifts in the sea ice marginal zone and is expected to dominate the Arctic of the future. Two-year-old sea ice, characteristic of the present, drifts with the transpolar drift...

Eco-Crossing: intelligent assistance for climate-friendly ferry connections Elsfleth, 2 July 2025 - Innovation meets everyday life: every day, numerous people commute between Farge and Berne on the Weser ferry. The Eco-Crossing project aims to make this everyday connection not only reliable, but also significantly more climate-friendly. The central question is: does a ferry always have to take the same route - even if wind and current conditions are constantly changing? The answer is provided by a learning assistance system that recommends the most efficient route in real time - based on current environmental and ship parameters. The aim is to reduce fuel consumption by up to 20 per cent and achieve considerable annual cost savings.

A BAAINBw tender, which expired on 23 June, provides for all three Sachsen-class frigates to be equipped with external gateways by 2026. The aim is to integrate the NATO data link Link 22 and the Joint Range Extension Applications Protocol C, which stands for long-range satellite-based communication, as an interim solution. This measure is part of a more comprehensive modernisation concept for the navy until the F127 enters service - and is exemplary of the "Marine 2025 course" approach. According to the tender, a Ship-Shore-Ship Buffer on Ship (SSSB) is to be installed on each of the three F124 class frigates by August 2026 so that the units can...

The German Motor Yacht Association (DMYV) is campaigning for the protection of harbour porpoises The aim of the project is to raise awareness of the harbour porpoise, the only whale permanently resident in German waters. As the DMYV announced in a press release, recreational skippers should actively contribute to the protection of the animals and their habitats. Detailed underwater noise measurements have now been carried out with recreational shipping in the North Sea. The sound measurements were carried out as part of the BUND project "Quiet for the harbour porpoises", which is funded by the Lower Saxony Bingo Environmental Foundation and the Lower Saxony Wadden Sea Foundation. The harbour porpoise, which measures up to approx. 160 cm in length and is on the Red List of...
