GEOTRACES 2014年中间数据产品(IDP2014)是国际GEOTRACES方案的第一个公开提供的数据产品，其中包含2013年底之前测量和质量控制的数据。它由两部分组成：(1)汇编200多种微量元素和同位素(TELL)以及经典水文参数的数字数据；(2)eGEOTRACES电子地图集，提供一个紧密相连的在线地图集，其中包括300多个部分情节和90个动画三维场景。IDP2014涵盖大西洋、北冰洋和印度洋，在大西洋表现出最高的数据密度。IDP2014中的TEI数据通过仔细评估交叉站点的内部校准结果和多个实验室的数据比较来进行质量控制。数字数据以多种格式提供，包括ASCII电子表格、Excel电子表格、NetCDF和海洋数据视图集合。除实际数据值外，IDP2014还包含数据质量标志和1-sigma数据误差值。质量标志和误差值对于数据过滤很有用。关于数据来源、分析方法和与数据有关的原创出版物的元数据以一种易于访问的方式与数据链接。EGEOTRACES电子地图集是IDP2014数据的可视化表示，提供了断面剧情和一种新的动画3D场景。盆地范围的3D场景允许同时查看来自多个邮轮的数据，从而提供大规模示踪剂分布的快速概述。此外，3D场景提供了地理和水深测量背景，这对于解释和评估观测到的示踪剂羽流以及对控制过程做出推断至关重要。(C)2015年提交人。爱思唯尔出版公司(Elsevier B.V.)
The GEOTRACES Intermediate Data Product 2014 (IDP2014) is the first publicly available data product of the international GEOTRACES programme, and contains data measured and quality controlled before the end of 2013. It consists of two parts: (1) a compilation of digital data for more than 200 trace elements and isotopes (TEls) as well as classical hydrographic parameters, and (2) the eGEOTRACES Electronic Atlas providing a strongly inter-linked on-line atlas including more than 300 section plots and 90 animated 3D scenes. The IDP2014 covers the Atlantic, Arctic, and Indian oceans, exhibiting highest data density in the Atlantic. The TEI data in the IDP2014 are quality controlled by careful assessment of intercalibration results and multi-laboratory data comparisons at cross-over stations. The digital data are provided in several formats, including ASCII spreadsheet, Excel spreadsheet, netCDF, and Ocean Data View collection. In addition to the actual data values the IDP2014 also contains data quality flags and 1-sigma data error values where available. Quality flags and error values are useful for data filtering. Metadata about data originators, analytical methods and original publications related to the data are linked to the data in an easily accessible way. The eGEOTRACES Electronic Atlas is the visual representation of the IDP2014 data providing section plots and a new kind of animated 3D scenes. The basin-wide 3D scenes allow for viewing of data from many cruises at the same time, thereby providing quick overviews of large-scale tracer distributions. In addition, the 3D scenes provide geographical and bathymetric context that is crucial for the interpretation and assessment of observed tracer plumes, as well as for making inferences about controlling processes.
