Field‑based greenhouse gas monitoring in Chinese ecosystems

Accurate greenhouse gas data from natural ecosystems is essential for understanding climate dynamics and protecting vulnerable habitats. Across China, researchers are increasingly turning to advanced in‑situ monitoring tools to capture real‑time emission patterns in lakes, wetlands, rivers, and other ecological environments. Understanding how greenhouse gases move through natural ecosystems is essential for modeling climate change and protecting sensitive habitats. Two recent research initiatives highlight how portable, high‑frequency monitoring tools are enabling scientists to study complex ecological processes with unprecedented accuracy.

High‑frequency flux monitoring at Hohai University 

At Hohai University, researchers have developed the Air‑Water Interfacial Flux Online Observation System, a platform capable of conducting rapid, in‑situ, and high‑frequency monitoring of key greenhouse gases, including CO₂, N₂O, CH₄, H₂O, CO, and NH₃. The system integrates an FTIR analyzer and is deployed across lakes, reservoirs, rivers, wetlands, and soils, ecosystems where greenhouse gas exchange is highly dynamic and spatially variable. Because measurements are taken at multiple locations simultaneously, the system offers an accurate spatial representation of emission fluxes.

These data enable researchers to explore the biogeochemical cycling of carbon, hydrogen, and nitrogen across the full ecosystem continuum: water → soil → plants → atmosphere. This integrative view helps scientists understand how environmental conditions, ecosystem structure, and human activity affect natural emission patterns.

Mangrove wetland research in Zhanjiang 

In southern China, the Guangdong Zhanjiang Mangrove Wetland Ecosystem National Observation Station, located within China’s largest mangrove reserve, uses the GT5000 Terra analyzer to quantify greenhouse gas emissions in a highly sensitive coastal habitat. The mangrove environment presents unique measurement challenges, including tidal fluctuations, complex root structures, and soils easily disturbed by sampling. Traditional methods involving soil extraction can unintentionally alter gas release. 

The GT5000 Terra’s portable, field‑ready design allows scientists to perform direct on‑site measurements without disturbing the environment. This produces more reliable data and enables researchers to observe how factors such as humidity, temperature, and seasonality influence emission patterns. Its ease of use makes repeated measurements throughout the year possible, allowing scientists to track emissions under different growth cycles and environmental conditions.

Implications for Ecosystem Research 

Together, these two projects demonstrate how field‑based, high‑frequency gas monitoring technologies are reshaping ecological research in China. From inland lakes to coastal mangroves, researchers can now explore continuous greenhouse gas fluxes with greater accuracy than ever before, strengthening climate models, informing conservation strategies, and deepening scientific understanding of natural carbon and nitrogen cycles.
