Key Laboratory of Global Change and Marine-Atmospheric Chemistry


The Key Laboratory of Global Change and Marine-Atmospheric Chemistry (GCMAC) of the Ministry of Natural Resources was established in 2002. Revolving around the needs of the country and the development of related disciplines, the GCMAC focuses on the offshore area of China, especially the Taiwan Strait and adjacent waters, the polar and sub-polar regions. With cross-disciplinary advantages and through observation experiments, theoretical analysis, and numerical simulation, the GCMAC investigates the physical and chemical processes, formation and development mechanisms of the marine-atmospheric system, and its impact on the marine environment and global change, especially the marine-atmospheric biogeochemical factors affecting climate sensitivity. It aims to provide scientific reference and basis for China’s marine sector to cope with climate change, develop a marine ecological civilization, and achieve a sustainable marine economy. 

The main research fields include marine-atmospheric biogeochemical circulation, polar ocean and atmospheric chemistry, global change and regional response. An interdisciplinary research team has been formed, mainly consisting of young and middle-aged scientists. There is a total of 40 scientific researchers, including auxiliary personnel in science and technology, students pursuing a doctoral degree and postgraduate students, among which 25 are on-the-job personnel, five researchers, seven associate researchers, and seven senior engineers.

The GCMAC is internationally known for its excellent scientific research in ocean acidification, carbon cycle, aerosols, biogenic elements (carbon, nitrogen, sulfur, iron, phosphorus, etc.), and other sea-air source and sink patterns, as well as the polar environment, and climate change impact and assessment. It has participated in all Chinese scientific expeditions to the north and south polar regions and undertaken the tasks of Program 863, Program 973, the key national scientific research special project, the key national R&D special project, national-level international cooperation projects, three key national fund projects, Special Project 908, the national public welfare project, etc. More than 300 papers (100 SCI papers) have been published in Science and Nature Climate Change as well as 17 monographs. Its scientific research achievements have won 15 provincial and ministerial science and technology awards (including one special prize and three first prizes) and 18 national authorized patents. In 2017, it was honored as the “Advanced Polar Expedition Group of China” by the Ministry of Human Resources and Social Security and the State Oceanic Administration.

In addition, the GCMAC has been actively engaged in cooperation and academic exchanges with research institutions at home and abroad. The collaborative research with institutions in countries such as the United States, Germany, Norway, Belgium, Finland, Canada, and South Korea has been very productive.
