7th CJK IMBeR Symposium

Time: 24.03.2016 - 26.03.2016
Location: JeJu, Republic of Korea

Variability in biogeochemical cycles and ecosystem dynamics in the marginal seas of the Northwest Pacific

Jeju International Marine Research and Education Center, Jeju, Republic of Korea


Marine scientists from China, Japan and Korea (CJK) have gathered to discuss and exchange ideas on marine biogeochemistry and ecosystem dynamics at the CJK symposium series that began under the auspices of GLOBEC in 2002. These have continued under IMBeR since GLOBEC ended in 2010. The focus has been the interrelationships between marine biogeochemical cycles and ecosystems, and the responses of marine systems to natural and anthropogenic forcing, especially in the Northwestern Pacific region. The 7th China-Japan-Korea IMBeR Symposium will focus on the impact of climate change and anthropogenic forcing on physical processes and biogeochemical cycles, ecosystem structure and functions, and fisheries in the marginal seas in the Northwestern Pacific region, and how these complex interactions, in turn, influence marine ecosystems and human society. Four sessions will discuss the following sub-themes:


  1. Recent inter-annual/decadal trends in circulation and ecosystem dynamics: The Northwestern Pacific region has experienced climatic changes ranging from the El Niño Southern Oscillation (ENSO) to multi-decadal scale variations, accompanied by rapid changes in the sea surface temperature and circulation patterns. In response to this, ecosystem level changes have been observed. This session will consider and compare the ecosystem responses in different parts of the region.    
  2. Anthropogenic impacts (eutrophication, atmospheric deposition, overfishing, increased CO2, etc.) on biogeochemical cycles and ecosystem dynamics.The Northwestern Pacific region is one of the most rapidly developing regions of the world. Consequently, marine ecosystems in the region are under ever-increasing impact of human activities. This session will compare how different stressors affect the different systems and how the multiple stressors interact to induce ecosystem responses.    

  3. Impact of Kuroshio Current on biogeochemical cycles and ecosystem of the marginal seas in the Northwest Pacific. The Kuroshio Current is the main driver of the regional material cycle distributing heat, salts and other materials. This session will focus on, in particular, how the variability of the Kuroshio Current influences the biogeochemistry and ecosystem dynamics in the region.     

  4. Abnormal ecosystem phenomena. Since the early 2000s, there have been frequent, unprecedented ecosystem phenomena, such as massive blooms of jellyfish and green/brown algae, suggesting that the ecosystems in the region might be becoming unstable. This session will consider the abnormal phenomena plaguing the region and discuss possible causes and their impacts.
