| description | Version 2 of the Global Ocean Data Analysis Project (GLODAPv2) data product
is composed of data from 724 scientific cruises covering the global ocean.
It includes data assembled during the previous efforts GLODAPv1.1 (Global
Ocean Data Analysis Project version 1.1) in 2004, CARINA (CARbon IN the
Atlantic) in 2009/2010, and PACIFICA (PACIFic ocean Interior CArbon) in
2013, as well as data from an additional 168 cruises. Data for 12 core
variables (salinity, oxygen, nitrate, silicate, phosphate, dissolved
inorganic carbon, total alkalinity, pH, CFC-11, CFC-12, CFC-113, and
CCl<sub>4</sub>) have been subjected to extensive quality control, including
systematic evaluation of bias. The data are available in two formats: (i) as
submitted but updated to WOCE exchange format and (ii) as a merged and
internally consistent data product. In the latter, adjustments have been
applied to remove significant biases, respecting occurrences of any known or
likely time trends or variations. Adjustments applied by previous efforts
were re-evaluated. Hence, GLODAPv2 is not a simple merging of previous
products with some new data added but a unique, internally consistent data
product. This compiled and adjusted data product is believed to be
consistent to better than 0.005 in salinity, 1 % in oxygen, 2 % in
nitrate, 2 % in silicate, 2 % in phosphate, 4 µmol kg<sup>−1</sup> in
dissolved inorganic carbon, 6 µmol kg<sup>−1</sup> in total alkalinity, 0.005
in pH, and 5 % for the halogenated transient tracers.<br><br>The original data and their documentation and doi codes are available at the
Carbon Dioxide Information Analysis Center
(<a href="http://cdiac.ornl.gov/oceans/GLODAPv2/" target="_blank">http://cdiac.ornl.gov/oceans/GLODAPv2/</a>). This site also provides access to
the calibrated data product, which is provided as a single global file or
four regional ones – the Arctic, Atlantic, Indian, and Pacific oceans – under
the <a href="http://dx.doi.org/10.3334/CDIAC/OTG.NDP093_GLODAPv2" target="_blank">doi:10.3334/CDIAC/OTG.NDP093_GLODAPv2</a>. The product files
also include significant ancillary and approximated data. These were
obtained by interpolation of, or calculation from, measured data.
This paper documents the GLODAPv2 methods and products and includes a broad
overview of the secondary quality control results. The magnitude of and
reasoning behind each adjustment is available on a per-cruise and per-variable basis in the online Adjustment Table. |
