Description:Floating macroalgae of Sargassum horneri (S. horneri) in the East China Sea (ECS) has increased in recent years, with ocean warming being one of the driving factors. Yet their possible origins, based on a literature review, are unclear. Here, using multi-sensor high-resolution remote sensing data and numerical experiments for the period of 2015–2023, we show two possible origins of the ECS floating S. horneri, one being local near the Zhejiang coast with initiation in January–February and the other being remote (> 800 km from the first) in the Bohai Sea with initiation in June–November. While their drifting pathways are revealed in the sequential remote sensing imagery, numerical experiments suggest that S. horneri from the remote origin (Bohai Sea) can hardly meander through the strong Yangtze River frontal zone, which may serve as a “wall” to prevent trespassing of surface floating seaweed to the south of the frontal zone, where S. horneri has a local origin.
