GLODAPv2 data are freely available, but appropriate credits to GLODAPv2 team and data originators
must be given in any publications that emerge from their use.
GLODAPv2 is described in two publications in Earth System Science Data (Olsen et al., 2016 and
Lauvset et al., 2016) and in one NDP document (Key et al., 2015). The NDP is a brief summary
of the two ESSD papers. Full citations are provided below.
Whenever GLODAPv2 is used, the following citations must be included:
For data and data product: Olsen et al., 2016 and Key et al., 2015
For mapped product: Lauvset et al., 2016 and Key et al., 2015
Citing the Earth System Science Data publications is essential as this gives the team traceable
citations and also enables tracking of GLODAPv2 use. This is important for justifying and sustaining

If you make heavy use of data from a single cruise or a limited set, please contact the PIs for possible
collaboration. The PIs normally possess insight on context and data, and collaboration leading to co-authorships
promotes further sharing of data.
Global Ocean Data Analysis Project version 2 or simply GLODAPv2 includes data from approximately one million
individual seawater samples collected from almost 800 cruises carried during the years 1972-2013. Extensive
quality control and subsequent calibration were carried out for salinity, oxygen, nutrient, carbon dioxide,
total alkalinity, pH and chlorofluorocarbon data. Following calibration, the data were used to produce global
climatology maps for many of the parameters. In addition to the data products and the mapped distributions,
all of the original data files without alteration other than formatting and unification of units are made
freely available along with whatever metadata was collected. An on-line cruise summary table provides data
access and additional information including references to publications that have used data from specific
