The Ocean Archive System searches our original datasets as they were submitted to us, not individual points or profiles. If you want to search and retrieve ocean profiles in a common format, or objectively analyzed fields, your better option may be to use one of our project applications. See: Access Data

| Title: | Table 1: Pb-210, Bi-210, and Po-210 activity measurements in rain, lake water, and dreissenid (Quagga) mussels collected in the Milwaukee Inner Harbor on Lake Michigan, Nov. 2018 (NCEI Accession 0292190) |
| Abstract: | This dataset contains data collected from 2018-11-04 to 2018-11-20. These data include depth. The instruments used to collect these data include Gamma Ray Spectrometer. These data were collected by James T. Waples of University of Wisconsin as part of the "The measurement and use of bismuth-210 as a tracer of particle flux in aquatic systems (Bi 210 measurement)" project. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2020-05-20. The following is the text of the dataset description provided by BCO-DMO: Table 1: Pb, Bi, Po Dataset Description: Pb-210, Bi-210, and Po-210 activity measurements in rain, lake water, and dreissenid (Quagga) mussels collected at the School of Freshwater Sciences’ slip in the Milwaukee Inner Harbor on Lake Michigan, Nov. 2018. This is table 1 in Waples (2020), Limnol. Oceanogr. Methods. |

| Supplementary information: | Acquisition Description: A detailed description of the methods for determining in situ 210Pb, 210Bi, and 210Po activities is given by Waples (2020). A second manuscript describing the use of Pb-210, Bi-210, and Po-210 as particle tracers in aquatic systems is currently in review for Limnology and Oceanography (March/2020). Water samples collected by submersible pump were weighed and filtered through nitrocellulose filters (0.45 um, 293 mm, Millipore) within two hours of sample collection to separate dissolved and particle-bound nuclide fractions of 210Pb, 210Bi, and 210Po. Yield monitors of 207Bi and 209Po (Eckert & Ziegler Isotope Products) were then added to both fractions. No lead monitor was required. Dissolved nuclide fractions ( Rainwater was collected at ground level (43.017719, -87.903000) in a large plastic barrel fitted with a funnel (0.216 m2 collection area) over a 40-h period during an extended rain event beginning at 17:20 (CST) on 03 November 2018. The funnel and barrel were rinsed before and after the collection event with a total of 0.4 L of 1 M HCl. Lake water samples (~ 50 L) for radionuclide analyses were collected from the slip (43.017835, -87.903521) with a submersible pump from a depth of 2 m on 08 November, 15 November, and 20 November 2018. Quagga mussels ( Dreissena rostriformis bugensis ) were collected from the slip wall (43.017829, -87.904407) on 29 November 2018. Each mussel was measured for shell length and sorted into two groups of large (range: 18–22 mm; geometric mean: 19 mm; n = 10) and small (10–16 mm; geometric mean: 13 mm; n = 20) mussels. Mussel tissue was separated from the shell, pooled by group into two glass beakers, and digested in concentrated HNO3. Shell-free biomass was estimated using the allometric equation m = 0.0018 × L3.11, where m is the tissue dry weight in mg (DW mg) and L is the mussel shell length in mm (Waples et al. 2017). Software used: - Maestro software (v. 6.04 and 6.06, Advanced Measurement Technology) - SigmaPlot (v. 11, Systat Software) - Excel (v. 2002, Microsoft) |
