researchers have discovered the deepest,most extensive chemosynthesis-based communities of organisms during an expedition to the Kuril-Kamchatka Trench and the western Aleutian Trench,according to a recent research article published in Nature.

​Recently, the International Big Science Program "Global Hadal Trench Exploration Program" (Global -HEP) led by IDSSE,CAS, has been officially approved by the Executive Committee of the United Nations Decade of Ocean Science for Sustainable Development.

China-New Zealand Manned Deep Dive Joint Expedition to the Puysegur Trench has Completed 32 Dives and Collected a Batch of Precious Samples

Global TREnD has completed the China-New Zealand joint manned deep-sea scientific expedition to the Puysegur Trench. For the first time, humans have dived to the deepest part of the Puysegur Trench.

On March 6, 2025, a significant research achievement in deep-sea fish studies was published in the international top-tier journal Cell.

Supported by the Global TREnD, the China-New Zealand joint scientific expedition team reembarked on 21st to launch the project of the second segment of the second voyage manned deep-sea expedition of the two countries, continuing to complete humanity's first scientific exploration of the Puysegur Trench.

the second China-New Zealand collaborative dive expedition to the Puysygur Trench, scheduled to take place from January to March of 2025. The Puysegur Trench is located in the southern part of the Tasman Sea, just off the southwestern coast of New Zealand.

Recently, the research team led by Research Fellow Hongzhou Xu published a research paper online in the international journal "Nature Communications". This research discovered for the first time the three-layer circulation structure in the deep layer of the Challenger Deep (CD) and revealed the mechanism driving the circulation structure.

​In 2024, a research team led by Dr. Xiaotong Peng reported the discovery of abiotic organic compounds in basalt from the oceanic crust of the Southwest Indian Ridge and proposed a novel molecular mechanism for its condensation published their findings in the Proceedings of the National Academy of Sciences (PNAS).
