Professor Stephen C. Maberly, a well-known ecologist specialized in rivers and lakes, visited IGCAS from October 19, 2012 to October 24, 2012.

Professor Stephen C. Maberly’s research interests focus on the ecology of rivers and lakes, as well as nutrients in rivers and lakes, especially the cycle of carbon. He serves on the editorial boards of Aquatic Botany and Freshwater Biology, and is an associate editor for the new SIL journal Inland Waters. He has been appointed as Senior International Visiting Professor of Chinese Academy of Science for two years since January 2011. 

On October 20th and 21st, Professor Stephen C. Maberly joined the members of the Group of Geochemical Processes of the Earth’s Surface and Eco-environmental Effects for a sailing field trip to investigate the river water from Liuguang River to Wujiangdu reservoir. The researchers took the on-line measurements of the water properties such as the water temperature, pH, concentration of chlorophyll a and CO2 partial pressure, and so on. Professor Stephen C. Maberly contributed valuable expert suggestions during the field trip.

During his stay in IGCAS, Professor Stephen C. Maberly presented two talks titled, respectively, “The role and study of lakes at national, regional and global scales” and “CO2 as an ecological factor in freshwaters”. His easy-to-understand introduction of his research theories and results delivered new research ideas and diverse research methods to the audience. At the end of the presentation, Professor Stephen C. Maberly had a lively discussion with the audience including CAS Academician LIU Congqiang.

Professor Stephen C. Maberly’s meaningful research leads to the better understanding of studying rivers and lakes systems which is one of the most-interested research areas for many IGCAS researchers, so IGCAS looks forward to strengthening communication with Professor Stephen C. Maberly and establishing a collaborative partnership with him as well.
