Dissolved Ga and Ba from GEOTRACES Rosette bottles R/V Knorr cruises KN199-04 and KN204-01 (GA03) in the Subtropical northern Atlantic Ocean from 2010-2011 (U.S. GEOTRACES NAT project)

<p>Lab-based measurements of dissolved Gallium (Ga)&nbsp;and Barium (Ba) from GEOTRACES Rosette bottles from the 2010 and 2011 US GEOTRACES cruises (GT10 and GT11).&nbsp;</p>

<p><strong>STATUS NOTE:</strong> These data were significantly updated on 30 August 2016. A volume correction had not been applied to the previous version, and thus all of the original values&nbsp;needed to be multiplied by 0.9805. This correction has been applied in the 30 August version, now available online. There were also some samples that were re-analyzed for Ba with the values revised accordingly. Additionally, the PIs withdrew the Pb data (in the original version) because higher quality Pb data are already available from these cruises.</p>

<p>Please note that some US GEOTRACES data may not be final, pending intercalibration results and further analysis. If you are interested in following changes to US GEOTRACES NAT data, there is an RSS feed available via the BCO-DMO <a href=\"http://www.bco-dmo.org/project/2066\" target=\"_blank\">US GEOTRACES project page</a> (scroll down and expand the \"Datasets\" section).</p>

本数据集包含2010年与2011年美国GEOTRACES航次（GT10与GT11）中取自GEOTRACES罗塞特采水器（Rosette bottles）样品的实验室溶解态镓（Gallium, Ga）与钡（Barium, Ba）测量数据。

**状态说明：** 本数据集于2016年8月30日完成重大更新。此前版本未应用体积校正，因此所有原始数值均需乘以0.9805。本次更新后的在线版本已完成该校正操作。另有部分钡（Ba）样品经重新分析后修正了对应数值。此外，项目首席研究员（Principal Investigators，PIs）撤回了原始版本中的铅（Pb）数据，原因是此类航次已公开更高质量的铅数据。

请注意：部分美国GEOTRACES数据集尚未最终定稿，仍需等待室内互校结果及进一步分析。若您希望追踪美国GEOTRACES NAT数据的更新动态，可通过BCO-DMO（生物与化学海洋学数据管理办公室）的<a href="http://www.bco-dmo.org/project/2066" target="_blank">美国GEOTRACES项目页面</a>获取RSS订阅源（请向下滚动并展开“数据集”板块）。
