Years after an earthquake and tsunami rocked Fukushima, Japan, we’re still not sure if it’s safe to swim in or eat fish from the Pacific.

Research by scientists at the Woods Hole Oceanographic Institution (and others) indicate that the radiation that leaked into the ocean after the partial meltdown of Fukushima Dai’ichi is restricted to the waters off of Japan. But with such an unprecedented event, they know they need to continue to monitor a huge area on both sides of the Pacific in order to be sure.

Our video for WHOI chemist Ken Buesseler’s initiative, Our Radioactive Ocean, raised awareness about his research— and funds for his innovative, crowdsourced research in the Pacific.
