Cs137 and Cs134 concentrations from Fukushima Radionuclide Project Dataset Description: <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>

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>

Establishing Radionuclide Levels in the Atlantic and Pacific Oceans Originating from the Fukushima Daiichi Nuclear Power Facility
<p>The March 11, 2011 earthquake in Japan and the subsequent tsunami damaged and disrupted cooling systems at the Fukushima Daiichi nuclear power facility causing contamination of land and seas surrounding the site, as well as food supplies and drinking water. Small but measurable quantities of radioactivity have been detected in the atmosphere over the United States, including aerosol samples collected at the Woods Hole Oceanographic Institution, where I-131 was seen to increase to detectable levels as of March 21-22, 2011.</p>
<p>With major funding from the Moore Foundation, as well as a contribution from the National Science Foundation through a 2011 Grant for Rapid Response Research (RAPID) and support from the Woods Hole Oceanographic Institution, collaborating investigators from the United States, Japan, Spain, Monaco, and the United Kingdom were able to obtain samples off Japan for an early assessment of impacts.</p>
<p>From June 4 through June 19, 2011, a research cruise was carried out aboard the RV Kaimikai-O-Kanaloa, a research vessel operated by the University of Hawaii. During the cruise, hundreds of samples were collected in an area off the coast of Japan as close as 30 kilometers from the Fukushima Nuclear Power Plant and extending as far out as 600 kilometers off shore. The essential components of the program include: radionuclide measurements of water and particles; a radioecological study of biota, especially species at the base of the food chain and key fish species and a physical oceanographic study to characterize transport and water masses. A baseline radionuclide data set for the Atlantic and Pacific was obtained along an east to west network of sampling stations. Three hundred sampling events took place at thirty major stations for a total of more than 1500 samples. Along with 41 CTD stations, bottle samples of salinity, oxygen, radionuclides, and particulates were taken to depths of about 1000 meters. <a href="http://data.bco-dmo.org/Fukushima/Fukushima_radionuclide_sampling_summary.pdf">A list of the radionuclides sampled and a sampling summary map</a> is available. One hundred net tows resulted in approximately fifty pounds of biological samples, including plankton and small fish. Daily samples of aerosol were also taken.</p>
<p>Early investigation following an accidental release of man-made radionuclides is key to understanding the magnitude of the release and the relationship to public health issues The research results also set the stage for the use of the longer lived radionuclides as tracers in subsequent studies by the community to understand ocean processes.</p>

<h3><strong>Protocol used for cesium water data submitted to BCO-DMO by Ken Buesseler</strong></h3>
<h4>Method for cesium-134 and -137 in seawater</h4>
<p>Surface samples were pumped directly into new, calibrated 20 liter plastic cubitainers. Deeper samples (20-1000 m) were collected with CTD/Rosette. We found that the sample processing improved with 1 micromol prefiltration, presumably due to remove of organic particulates. This will not impact total Cs activities as the measured 137Cs and 134Cs on the 1 micromol filters averaged only &lt; 0.04% of the total during this cruise, consistent with the soluble nature of Cs in seawater.</p>
<p>Following collection, samples were acidified to pH 1-2 with JT Baker ultrapure nitric acid (130 mL per 22 L seawater). A stable 133Cs carrier (25 mg per mL standard, 1 mL per sample) was added for calibration of Cs extraction on the resin columns. Samples were allowed to equilibrate for at least 1 hour and an initial aliquot of sample was removed. Samples were extracted onto an ion exchange resin made of the organic polymer polyacrylonitrile, (PAN) and ammonium molybdophosphate (AMP) (1). Precleaned (with 0.1 N nitric acid) biorad glass chromatography columns (1.0x10 cm) were filled with 5 mL AMP-PAN resin in 0.1 N nitric acid. A frit was added above the resin to prevent re-suspension. Resin was allowed to settle for more than 1 hour before processing. Samples were pumped directly from cubitainers through the resin column at a flow rate of 30-35 mL per minute. Eluted sample was collected into cleaned cubitainers and a final solution aliquot was taken to determine the column extraction efficiency by measuring stable 133Cs.</p>
<p>AMP-PAN resin was transferred to a vial and gamma counted while still wet for 134Cs and 137Cs isotopes using closed-end coaxial well detectors in the lab. Samples were counted until counting errors on all Cs peaks were generally below 5-10% (depending on sample activity). Samples with low activities were counted for 24-48 hours. Gamma spectrometers were calibrated with a range of 134Cs and 137Cs standards purchased from Eckert and Ziegler. The 137Cs peak at 661 keV and 134Cs peaks at 604 and 795 keV were identified and analyzed with Aptec software.</p>
<p>To check for column recoveries, initial and final sample aliquots containing stable cesium were diluted with 5% ultrapure nitric acid and analyzed on an Element 2 ICP-MS (Thermo Fisher Scientific, WHOI plasma facility) equipped with PFA MicroFlow nebulizer, quartz spray chamber and regular cones. Recovery corrections were applied to measured 134Cs and 137Cs activities with an average recovery of 93 plus/minus 5% standard deviation.</p>
<p>Calibration standards were run using this new AMP-PAN method for 137Cs. We found good agreement between archived water from the Sargasso Sea collected in 1978 (internal WHOI lab standard 137Cs = 3.4 plus/minus 0.4 Bq m-3) and results of triplicate samples analyzed here (3.7 plus/minus 0.2 Bq m-3). Similarly, we measured a 137Cs activity in a single 5 L sample of 369 plus/minus 8 Bq m-3 in an IAEA Irish Sea water reference material, IAEA-443, which has a 95% confidence limit of 340-370 Bq m-3 (2).</p>
<p>The concentration of cesium isotopes in water is reported in units of Bq (1 Becquerel = one disintegration per second) per unit volume (Bq m-3). All activities are decay corrected to April 6th, the date of the maximum direct radioactivity discharge into the ocean (3).</p>
