        abstract:  This dataset contains chemical and physical data collected on R/V Thomas G. Thompson during cruise TN303 from 2013-10-29 to 2013-12-18. These data include Nitrogen, Si, depth, depth_bottom, and water pressure. The instruments used to collect these data include Isotope-ratio Mass Spectrometer and Niskin bottle. These data were collected by Dr Mark Brzezinski of University of California-Santa Barbara as part of the "GEOTRACES Pacific Section: Resolving Silicon Isotope Anomalies in the Eastern Pacific (GEOTRACES EPZT Silicon Isotope)" and "U.S. GEOTRACES East Pacific Zonal Transect (U.S. GEOTRACES EPZT)" projects and "U.S. GEOTRACES (U.S. GEOTRACES)" program. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2018-09-11. The following is the text of the dataset description provided by BCO-DMO: Profiles of stable isotopes of silicon in silicic acid from the US GEOTRACES EPZT cruise Dataset Description: Profiles of stable isotopes of silicon in silicic acid from the US GEOTRACES EPZT cruise.
        purpose:  This dataset is available to the public for a wide variety of uses including scientific research and analysis.

        supplementalInformation:  Acquisition Description: Sampling protocol followed the “ Sampling and Handling Protocols for GEOTRACES cruises " (PDF). Also see the "Si Natural Abundance Preparation" procedure (PDF) Briefly: Water samples were collected with a conventional CTD and rosette as Si isotopes are not contamination prone. Water samples were filtered through a polyethersulfone filter cartridge directly from each sampling bottle using silicon tubing and stored in either high density polyethylene or polypropylene bottles that were pre-cleaned by an overnight soak in 10% ACS grade HCl and rinsed with high purity deionized distilled water (> 18 MΩ - cm) and stored at room temperature. Analytical methodology followed Brzezinski et al. (2006): Brzezinski, M. A., J. L. Jones, C. P. Beucher, and M. S. Demarest. 2006. Automated determination of silicon isotope natural abundance by the acid decomposition of cesium hexafluosilicate. Anal. Chem. 78 : 6109-6114. https://doi.org/10.1021/ac0606406
