Kenneth Buesseler studies methods of detecting radioactivity in oceans. Based on these measurements, he investigates how plankton particles can facilitate CO2 absorption in the ocean. He conducted tests in the 1980s after the Chernobyl disaster and was able to measure how quickly thorium particles sank to the bottom of the ocean. His research gained world headlines last year when he found high levels of radioactive contamination in fish caught off the east coast of Japan some 18 months after the nuclear disaster at Fukushima.
