要旨:
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. (C) 2015 The Authors.
