W5 Monitoring and Assessment of Environmental Radioactivity in the North Pacific

Co-sponsor: Scientific Committee on Oceanic Research (SCOR)

Co-Convenors:
Yusheng Zhang (China)
Kathryn A. Higley (USA)

Invited Speakers:
Michio Aoyama (SCOR)
Minhan Dai (SCOR)
Ronald Szymczak (Nuclear and Oceanographic Consultant, Tradewinds)

The Marine Environmental Quality Committee’s area of responsibility is to promote and coordinate marine environmental quality and interdisciplinary research in the North Pacific. This workshop has three objectives: 1. To coordinate with external expert groups, 2. To review the situation and to discuss the information gaps and deficiencies in monitoring and assessment of the Environmental Quality of Radioactivity and its impact on marine ecosystems in the North Pacific, especially since the “3·11” Fukushima Nuclear Accident, and 3. To exchange information on new techniques and methodologies for monitoring and assessment of the environmental quality of radioactivity in the marine environment, and to discuss development trends and research priorities. The main topics of the workshop include: 1. the current situation of environmental quality of radioactivity and its effect on marine ecosystems in the North Pacific, 2. new techniques for the analysis of radionuclides in the marine environment and 3. assessment of the radiological risk to non-human species. The workshop will invite experts in relevant fields, and welcome reports on research and progress in the above topics with regard to the monitoring and assessment on the marine environmental quality of radioactivity in the North Pacific.
