China Confirms Deaths Of 2 Coast Guards After Collision Near Disputed Scarborough Shoal
China’s Coast Guard confirmed the deaths of two personnel, Yi, 21, and Cheng, 25, following a recent collision near the disputed Scarborough Shoal. The incident occurred August 11, 2025, during a “maritime rights protection operation” in the South China Sea. This event underscores escalating tensions in the region, following the sinking of a Vietnamese cargo ship near Fiery Cross Reef.
Unveiling deep-sea benthic biodiversity in the northern South China Sea through environmental DNA metabarcoding
A comprehensive environmental DNA (eDNA) metabarcoding study has revealed unprecedented insights into the benthic biodiversity of the northern South China Sea’s Qiongdongnan Basin, a region critical for natural gas hydrate resources. Researchers identified 334 benthic faunal species across cold seeps, gas hydrate stable zones, and non-gas hydrate zones, demonstrating clear habitat-specific community structures largely governed by deterministic processes like variable selection.
Cargo Ship With 62 People Onboard Sinks Off Chinese-Occupied Shoal In South China Sea
A Vietnamese cargo ship, *Khoi Nguyen 18*, has sunk in the South China Sea, approximately off Fiery Cross Reef, a Chinese-built artificial island within the contested Spratly Islands. The incident occurred on Saturday and involved 62 individuals onboard. This event underscores the complex geopolitical and environmental factors impacting maritime operations in the region. Related coverage on our site details the challenges of maritime salvage, as seen in the recent freeing of the *Onego Otra* after a four-week grounding in the St. Lawrence River.
China Installs World’s Largest Offshore Wind Converter Station In South China Sea
China has achieved a significant milestone in renewable energy infrastructure with the installation of the world’s largest offshore wind converter station, dubbed the "Heart of Offshore Wind." Located approximately 100 kilometers off the coast of Yangjiang, Guangdong Province, this facility represents a major advancement in harnessing wind power from the South China Sea. The project underscores China's commitment to expanding clean energy sources.
45 Rescued, 17 Missing After Cargo Ship Sinks In South China Sea
