Fukushima‐ a view from the ocean
A public lecture by Dr. Ken Buesseler, Senior Scientist, Woods Hole Oceanographic Institution, USA
The triple disaster of the March 11, 2011 earthquake, tsunami, and subsequent radiation releases at Fukushima Dai‐ichi were unprecedented events for the ocean and society. This pubic lecture will provide an overview and 8 year update regarding the radioactive contaminants released from the Fukushima Daiichi Nuclear Power Plants. The talk will consider the radioactive world we live in and address the specific fate of Fukushima radionuclides in the ocean, with an eye to the future ocean. The emphasis is on the radioactive forms of cesium, though other radionuclides are also considered. Topics include: sources from atmospheric and ocean discharges in 2011; a Pacific Ocean time‐series that tracks the transport of contaminants across the ocean; an extended time‐series in marine fish that examines species specific variability in radionuclide content; and a discussion of the burial of particle associated contaminants on the seafloor. The look to the future includes estimates of ongoing releases from groundwater associated with beach sands in comparison to other land sources, such as rivers and operations during decommissioning. We end by considering the long term trends in radioactivity levels in marine biota and sediments, with comparisons to other sites in the world, and open discussion on key issues that have yet to be resolved, such as the fate of contaminated water in the storage tanks and discovery of cesium microparticles.
The talks will be of several formats, from a panel format with one or more additional speakers, but most will be individual presentations by Dr. Buesseler. While the talk will be in English (about 30‐45 min), slides will have Japanese text, and a one page Japanese language hand‐out will be provided. Questions from the audience will be encouraged (about 15 min) with assistance from local hosts to translate questions into English and back into Japanese. The event on March 24 will be part of a Safecast event with various citizen scientists groups presenting.

Short bio Ken Buesseler
Dr. Buesseler is a Senior Scientist at the Woods Hole Oceanographic Institution who specializes in the study of natural and man‐made radionuclides in the ocean. His work includes studies of fallout from atmospheric nuclear weapons testing, assessments of Chernobyl impacts on the Black Sea, and examination of radionuclide contaminants in the Pacific resulting from the Fukushima Daiichi nuclear power plants.
Dr. Buesseler has served as Chair of the Marine Chemistry and Geochemistry Department at WHOI, and two years as an Associate Program Director at the US National Science Foundation, Chemical Oceanography Program. In 2009 he was elected Fellow of the American Geophysical Union and in 2018 as a Fellow of the American Association for the Advancement of Science (AAAS). In 2011 he was noted as the top cited ocean scientist by the Times Higher Education for the decade 2000‐2010, and he is a foreign member of the Royal Netherlands Academy of Arts and Sciences. He was honored in 2013 by the Japan Society for the Promotion of Science with their highest level Fellowship award for overseas researchers “who are Nobel laureates or recipients of similarly high level international prizes who currently occupy a leading position in their subject field”. He is currently Director of the Center for Marine and Environmental Radioactivity at WHOI (http://www.whoi.edu/CMER), and regularly speaks to public audiences and engages citizens as part of Our Radioactive Ocean (http://ourradioactiveocean.org ).
