A new study found that cultivating seaweed species alongside marine finfish in integrated multi-trophic aquaculture (IMTA) operations, where seaweeds receive nutrient-rich effluent from fish production, can significantly reduce—and even eliminate—key waste products from marine finfish farming.

A new study published in the journal npj Climate and Atmospheric Science, shows that electronically tagged sharks can serve as mobile sensors, collecting ocean climate data in regions that are difficult to observe using conventional methods.

Tiny plankton shells used to reconstruct past polar ocean temperatures may contain two different chemical stories, a new study by iC3 researchers has found. 

The work shows that Neogloboquadrina pachyderma, a key species in polar climate archives, can grow an outer shell crust with a different chemical make-up from the shell beneath it, even when both are grown in the same conditions.

This discovery could help scientists produce more accurate records of past ocean change.

A major new report published today warns that nature loss is not just an environmental issue, it is already disrupting our food system, threatening catastrophic impacts on our economy and society. The report has been produced by the UK’s Institute and Faculty of Actuaries and Anglia Ruskin University.

30 April 2026 / Kiel / Mindelo. Tomorrow, fourteen Master’s students in the West African Master’s programme ‘Climate Change and Marine Sciences’ will begin their two-week training and research voyage aboard the research vessel POLARSTERN. Travelling from Mindelo in Cabo Verde to Bremerhaven, Germany, they will carry out physical, biogeochemical and biological measurements together with ten experienced scientists. This is the fourth time that the Floating University is taking place under the leadership of GEOMAR Helmholtz Centre for Ocean Research Kiel. This initiative significantly contributes to the goals of the UN Decade of Ocean Science and is funded by the German Federal Ministry of Research, Technology and Space (BMFTR) as part of the WASCAL programme (West African Science Service Centre on Climate Change and Adapted Land Use).

A year-long environmental DNA study of New York City’s East River involving single liter water samples revealed an unexpectedly detailed snapshot of life in and around the city, from weekly and seasonal shifts in fish species and abundance to urban wildlife activity and even New Yorkers’ diets.

The findings suggest that urban waterways anywhere could become continuous biosensors, tracking biodiversity, habitat restoration outcomes, and human impacts in real time.
