Hydrocast isotope concentrations of Cesium 137 and 134 from the R/V Ka`imikai-O-Kanaloa KOK1108 cruise in June 2011 in the Northwest Pacific Ocean (Fukushima Radionuclide Levels project)

<p>This dataset includes radionuclide results determined from high purity germanium detectors and calibrated against IAEA standards as described in Buesseler et al. (2012). Concentrations of Cesium isotopes Cs137 and Cs134 are reported in Bq per meter^3 from an underway system that was hull-mounted at a depth of approximately 2 meters.</p> <p><strong>Modification History:</strong><br /> <br /> Data version 2 (2012-12-18) replaced Data version 1 (2012-10).<br /> Note that updated Cesium data measurements were contributed by Ken Buesseler in October 2012.&nbsp; The online dataset has been revised to include these measurements.&nbsp; A PDF version of these updates is available (See supplemental file&nbsp;WHOI_KOK_Cs_data_Table_S1_Oct_2012_update.pdf). The data are in the same format as Table S1 in the 2012 Buesseler et al. PNAS paper cited below. The net difference in old vs. new is 0.3%, but a few values have changed by 5% or more. The update reflects a second run of the chemical yields measured for stable Cs by ICPMS.</p> <p>&nbsp;</p>本数据集包含通过高纯锗探测器（High Purity Germanium Detector）测得的放射性核素检测结果，且按照Buesseler等人（2012）所述的方法，以国际原子能机构（International Atomic Energy Agency, IAEA）标准完成校准。文中报告的铯同位素Cs137与Cs134浓度单位为贝可每立方米（Bq/m³），数据取自安装于约2米水深船壳处的走航式测量系统。 <strong>修改历史：</strong> 数据版本2（2012-12-18）替代了数据版本1（2012-10）。 请注意，Ken Buesseler于2012年10月贡献了更新后的铯同位素测量数据。在线数据集已完成修订以纳入该批新增测量数据。本次更新的PDF版本可通过补充文件WHOI_KOK_Cs_data_Table_S1_Oct_2012_update.pdf获取。本数据集的数据格式与下文引用的2012年Buesseler等人发表于《美国国家科学院院刊》（Proceedings of the National Academy of Sciences, PNAS）的论文中的表S1保持一致。新旧数据的净差异为0.3%，但部分数值的变动幅度达到5%及以上。本次更新对应通过电感耦合等离子体质谱法（Inductively Coupled Plasma Mass Spectrometry, ICP-MS）测定的稳定铯化学产率的二次复测结果。
