AI and satellite imagery reveals expanding footprint of human activity at sea
Summary: A study by Global Fishing Watch reveals 75% of the world's industrial fishing vessels are hidden from public view. Using AI and satellite imagery, researchers created the first global map of large vessel traffic and offshore infrastructure, uncovering previously unmonitored activity. The study also shows a 12% drop in fishing activity during the COVID-19 pandemic, while offshore energy development surged, with wind turbines more than doubling. This technology can help tackle climate change by improving greenhouse gas emissions estimates and informing wind development.
