Radionuclides in seawater have been reported from the Fukushima plant's discharge canals, from coastal waters five to ten kilometers south of the plant, and from 30 kilometers offshore. "Levels of some radionuclides are at least an order of magnitude higher than the highest levels in 1986 in the Baltic and Black Seas, the two ocean water bodies closest to Chernobyl," says Buesseler. He has been awarded a rapid-response grant from the National Science Foundation's (NSF) Division of Ocean Sciences to establish baseline concentrations of several radionuclides in the Atlantic and Pacific Oceans. "Finding this information early on is key to understanding the severity of the releases and related public health issues," says Buesseler. He and colleagues will establish a baseline radionuclide data set for the Atlantic and Pacific Oceans, using an east-to-west network of sampling stations where the ability to retrieve ocean water samples already exists.
