The China Geological Survey has released results from nearly two decades of marine geological surveys conducted across China's eastern waters, including the Bohai Sea, the Yellow Sea and the East China Sea.

Chinese researchers have produced a geochemical atlas of seabed sediments in the region based on systematic research. The atlas provides precise data intended to support coastal and marine spatial planning, ecological and environmental protection and resource exploration.

The study integrated surface sediment measurements with machine learning data from more than 20,000 sampling sites. Researchers said the effort formed the most extensive, multidimensional and reliable geochemical dataset to date for China's eastern waters.

The comprehensive geochemical analysis of sediments covered the full extent of China's eastern marine zones, according to authorities.
