The data in the HAM database were collected from about 90 literature citations, which include published papers; annual reports by the Hydrographic Department, Maritime Safety Agency, Japan; and unpublished data provided by individuals. The data of concentrations of<jats:sup>90</jats:sup>Sr,<jats:sup>137</jats:sup>Cs, and<jats:sup>239,240</jats:sup>Pu have been accumulating since 1957–1998.

The spatial variation of sampling stations in the HAM database is heterogeneous, namely, more than 80% of the data for each radionuclide is from the Pacific Ocean and the Sea of Japan, while a relatively small portion of data is from the South Pacific. This HAM database will allow us to use these radionuclides as significant chemical tracers for oceanographic study as well as the assessment of environmental affects of anthropogenic radionuclides for these 5 decades. Furthermore, these radionuclides can be used to verify the oceanic general circulation models in the time scale of several decades.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1382825895695093761","@type":"Researcher","foaf:name":[{"@value":"Michio Aoyama"}],"jpcoar:affiliationName":[{"@value":"Geochemical Research Department, Meteorological Research Institute, Nagamine 1-1, Tsukuba, Ibaraki 305-0052, Japan"}]},{"@id":"https://cir.nii.ac.jp/crid/1382825895695093760","@type":"Researcher","foaf:name":[{"@value":"Katsumi Hirose"}],"jpcoar:affiliationName":[{"@value":"Geochemical Research Department, Meteorological Research Institute, Nagamine 1-1, Tsukuba, Ibaraki 305-0052, Japan"}]}],"publication":{"publicationIdentifier":[{"@type":"EISSN","@value":"1537744X"}],"prism:publicationName":[{"@value":"The Scientific World JOURNAL"}],"dc:publisher":[{"@value":"Wiley"}],"prism:publicationDate":"2004","prism:volume":"4","prism:startingPage":"200","prism:endingPage":"215"},"reviewed":"false","dc:rights":["http://creativecommons.org/licenses/by/3.0/"],"url":[{"@id":"http://downloads.hindawi.com/journals/tswj/2004/321515.pdf"}],"createdAt":"2005-03-23","modifiedAt":"2016-08-23","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1360002218637522432","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Fukushima Daiichi–Derived Radionuclides in the Ocean: Transport, Fate, and Impacts"}]},{"@id":"https://cir.nii.ac.jp/crid/1360004231397566592","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Estimate of Fukushima-derived radiocaesium in the North Pacific Ocean in summer 2012"}]},{"@id":"https://cir.nii.ac.jp/crid/1360004232352615552","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Reconstruction of anthropogenic 129I temporal variation in the Japan Sea using a coral core sample"}]},{"@id":"https://cir.nii.ac.jp/crid/1360004240201330560","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Transport of FNPP1-derived radiocaesium from subtropical mode water in the western North Pacific Ocean to the Sea of Japan"}]},{"@id":"https://cir.nii.ac.jp/crid/1360017282436156032","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Evaluating the transport of surface seawater from 1956 to 2021 using\n                  <sup>137</sup>\n                  Cs deposited in the global ocean as a chemical tracer"}]},{"@id":"https://cir.nii.ac.jp/crid/1360285706358613632","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"134Cs and 137Cs in the North Pacific Ocean derived from the March 2011 TEPCO Fukushima Dai-ichi Nuclear Power Plant accident, Japan.
