From June 16-18, the Ministry of Natural Resources’ East China Sea Bureau
deployed research vessel Xiangyanghong 22 to survey China’s jurisdictional
waters east of Taiwan island. The multidisciplinary campaign collected seawater
environmental DNA (eDNA), seabird and cetacean observations, marine chemistry
and hydro‑meteorological data to support habitat mapping, ecosystem health
assessment and marine biodiversity protection in the area.
