The 2nd Open Science Meeting on HABs and Eutrophication was held 18-21 October 2009, Beijing, China.
A special issue of the CHINESE JOURNAL OF OCEANOLOGY AND LIMNOLOGY (Vol. 29, No. 4, pp. 719-916) has been published containing selected papers contributed to the 2nd Open GEOHAB Science Meeting on Eutrophication and HABs held in Beijing in 2009. The Guest Editors for the special issue are of P.Glibert, M.Zhu, M. Burford and Mingjiang Zhou.
Eutrophication is recognized as one of the factors contributing to the increasing proliferation of harmful algal blooms in coastal areas worldwide. The first Open Science Meeting on “HABs in eutrophic systems” was held in Baltimore in 2005. This second meeting is designed to bring experts together from around the world to review the current state-of-the-art knowledge on eutrophication and HABs, and to foster international collaboration on this critical global issue

More than 130 participants from 23 countries attended this event. It was particularly appropriate that this meeting was held in China, as the rate of nutrient loading to coastal waters in China has increased rapidly over the past several decades with the rapid industrialization of this country, and eutrophication-related HAB events are now common along the Chinese coast. As noted by Mingjiang Zhou, co-convener of the conference, “The international gathering of scientists in Beijing for the GEOHAB HABs and Eutrophication conference will help to inform local managers of the importance of this issue for China.” The conference featured seven keynote presentations, ranging from reviews of the rapidly expanding HAB events and their impacts throughout Chinese waters in the past decade (Mingyuan Zhu), to global estimates of the expanding distribution and impacts of Nocticula scintillans (Paul Harrison), to nutrient discharge from expanding aquaculture operations and their impacts (Lex Bouwman and Sandor Mulsow). Participants also heard local reviews of eutrophication-related HAB events in the Yucatan Peninsula, Mexico (Jorge Herrera Silveira), to the Gulf of Oman (Adnan Al-Azri). Bioengineering approaches to the problems of cyanobacterial blooms in the Baltic Sea were also addressed (Wilhelm Graneli). Thus, the goal of global networking was achieved without question. Contributed talks described a broad range of topics, underscoring many aspects of the complexity of the relationships of HABs with nutrients described above. Among the common themes were the impacts of sewage discharge in the United States and in Hong Kong, the effects of varying stoichiometric ratios in many regions and with respect to the growth of numerous species, factors promoting the expansion of cyanobacterial blooms, and interactions of anthropogenic nutrients, and regional and global climate change. Many new approaches and technologies were also highlighted. To further the dialogue and the sharing of information on this important topic, a special issue of the Chinese Journal of Oceanology and Limnology is being prepared to capture the highlights of this meeting. Two types of papers will be accepted: regular manuscripts and notes. The Core Research Project on HABs and Eutrophication aims to continue the tradition of Open Science Meetings, first conducted in Baltimore, MD, USA, in 2005, through a Third Open Science Meeting in several years— most likely in Europe. Given the rapid advance in knowledge and application of new techniques and models, and the expanding impact of eutrophication globally, it can be projected that there will be much to report in a few years’ time.
