The presence of the marine bacterium Vibrio vulnificus, which is potentially dangerous to humans, can now be predicted up to five weeks in advance in the Baltic Sea using artificial intelligence (AI). A research team led by the Leibniz Institute for Baltic Sea Research Warnemünde (IOW) reached this conclusion by combining high-resolution environmental, satellite, and microbiome data in an AI-based analysis. The study, recently published in “Water Research,” shows that this approach allows for a much more precise identification of risk periods than was previously possible. Furthermore, the IOW is testing an AI-supported drone measurement program for local Vibrio warning systems.
