International Symposium on Harmful Algal Blooms and Hypoxia in Global Change


From May 25th to 26th, the Symposium on Harmful Algal Blooms and Hypoxia in a Changing Ocean was held in Hangzhou, Zhejiang Province. More than 150 experts and scholars from 10 countries and regions including the United States, Japan, Malaysia, and the Philippines participated in the conference. The symposium aims to promote the integration and joint research of harmful algal blooms and marine hypoxia, share the data and technical achievements of ocean observations and numerical predictions, and gain a deeper understanding of the threatens to the health of offshore ecosystems by  eutrophication.

    The symposium set up 7 specially invited reports, 17 oral reports, 32 posters, and concentrative discussions. The chairman of the symposium is the Dr. CHAI Fei, director of the State Key Laboratory of Satellite Ocean Environment Dynamics. Academician SU Jilan of the Chinese Academy of Sciences and Dr. HUANG Daji, deputy director general of the Second Institute of Oceanography, State Oceanic Administration made the opening address.

    Academician SU Jilan first reviewed the status and trends of eutrophication in China's offshore waters and the environmental problems caused by red tides and hypoxia. The participating experts focused on different angles and levels, such as the characteristics of offshore eutrophication and the source of nutrients, the systematic changes of the offshore ecological environment, the mechanism of harmful algal bloom community evolution, the harmful algal bloom monitoring and prediction technology, and the hypoxia of China's offshore water bodies, the association mechanism between hypoxia and seawater acidification, and the response of China's offshore ecological disasters to global climate variability. The atmosphere of the concentrated discussion session was very active. Young “newcomers” and senior scholars expressed their opinions freely, deepening the exchanges between various disciplines and laying the foundation for further interdisciplinary cooperation.

    The conference was hosted by the Second Institute of Oceanography, State Oceanic Administration, and  jointly hosted by State Key Laboratory of Satellite Ocean Environment Dynamics, the Key Laboratory of Marine Ecosystems and Biogeochemistry of the State Oceanic Administration,  Marine Sciences Academy of Zhejiang Province, and the National Key R&D Project “High-Resolution Ecological Environmental Numerical Prediction System of China Offshore and Pacific Ocean”and the China APEC Cooperation Fund “Asia-Pacific Red Tide Causes and Their Mobile Diffusion Mechanisms”, and co-organized by South China Sea Institute of Oceanology, CAS, State Key Laboratory of Marine Environmental Science, Xiamen University, and Harmful Algal Bloom Ecological committee of North Pacific Marine Science Organization PICES.
