The Beibu Gulf Winter Scientific Expedition

From January 6 to 26,Yuxin carried out a 20-day sampling mission aboard the research vessel Lanbo 1 in the Beibu Gulf. During this expedition, a rich collection of atmospheric, seawater, and sediment samples was successfully obtained.

These samples, together with those collected by Hangyi during the summer of 2025, will jointly support ongoing research on marine environmental pollution processes in the region. The integrated dataset is expected to provide crucial insights into the current environmental status of the Beibu Gulf.

For Yuxin, the journey was not only scientifically fruitful but also a memorable life experience. He witnessed breathtaking sunrises and sunsets over the sea and gained a deeper appreciation for the unique stories that unfold through scientific exploration.

And the nearshore work was completed by Hangyi and Xuelin.Hangyi was responsible for onboard sampling, mainly collecting water and sediment samples, while Xuelin conducted the pretreatment of the large-volume water samples in the laboratory at Beibu Gulf University. Both of them successfully accomplished their tasks.

Beibu Gulf University

On January 11-12, Shizhen and Gan went to Beibu Gulf University (北部湾大学)in Qinzhou (钦州) for the annual meeting of the Field Station of Pinglu Canal (平陆运河河口海湾生态系统野外科学观测研究站), amid which Zhizhen was able to see Xuelin(雪琳) and Hangyi(航毅) who were working in the lab of the university for pretreatment of our water samples collected from the coast of Beibu Bay. Both of them had been working very hard in the lab and Hanyi also on the sampling boat. We met as well Professors Wang Yinghui (王英辉) of Guangxi University and Tang Jianhui (唐朝辉)of Yantai Institute of Coastal Zone CAS, and jointly visited the Centaury Project of Pinglu Canal (平陆运河). It is very excited for us to meet occasionally there!

Field Trip to Hani Terraced Fields

🌾Journey to the Hani Terraces
From October 23 to November 2, 2025, the “Soil Excavation Team” composed of Fan, Xiao, Yuxin, and Hangyi, conducted fieldwork at the Hani Terraced Fields in Yuanyang County, Yunnan Province.

Recognized as a UNESCO World Cultural Heritage Site, the Hani Terraces are a masterpiece of human wisdom and nature’s artistry. For more than 1300 years, generations of Hani people have sculpted the mountainsides into cascading paddy fields, nourished by a centuries-old forest-village-terrace-river ecosystem that still thrives today.

🌱Digging into the Terraced Earth

Over several days of fieldwork, the team ascended from the lush valleys at 800 m to the misty ridges at nearly 2000m, collecting paddy soil profiles along the way. Each layer of soil tells a story about how carbon accumulates, transforms, and moves within this centuries-old agricultural landscape.

The samples will be used to analyze soil organic and black carbon contents and isotope compositions, shedding light on carbon cycling processes and contributing to understanding the climate resilience of traditional farming systems.

👣Challenges, Smiles, and Stories Along the Terraces

The slippery terraces, steep trails, and sudden mountain mists made the fieldwork challenging. Yet every shovel of soil, every set of measurements, and every laugh shared on the rice paddies make the journey worthwhile.

We are especially grateful to the Hani farmers and village committees for their warm support. Their stores about traditional irrigation and terrace management helped us appreciate the enduring vitality of this landscape.
