Scientists harness AI to discover a rise in algae across the global ocean
Researchers from the University of South Florida and NOAA have used artificial intelligence to analyze more than 1.2 million satellite images and identify global trends in floating algae.
The study found that floating algae blooms are increasing across the ocean. From 2003 to 2022, microalgal scum increased by around 1% per year, while macroalgal blooms increased by 13.4% per year in parts of the tropical Atlantic and western Pacific.
This is important because floating macroalgae such as Sargassum and Ulva can provide habitat and nursery areas for marine life. However, when large blooms reach coastal areas, they can also affect tourism, coastal economies, human health and marine ecosystems.
The research highlights how AI and satellite monitoring can help scientists better understand long-term changes in ocean ecosystems.
