GLODAPv2 data product released


A new interior ocean carbon relevant data product: GLobal Ocean Data Analysis Project version 2, GLODAPv2 was just released. CPO’s Climate Observation Division supported this effort.
This version is a major update of the original GLODAP (2004) and includes Data from 724 cruises spanning 1972 to 2013. GLODAPv2 includes all data from the original GLODAP, data from CARINA and PACIFICA, and data from 168 new cruises.

All data have been evaluated for measurement bias and adjusted appropriately, using a consistent method. The end result is the most comprehensive and rigorously quality controlled ocean interior data product for marine biogeochemistry studies.
GLODAPv2 consist of three elements:

  • a data base with original cruise data, as submitted by individual data providers but updated to WOCE Exchange format;
  • a merged data product, with measurement biases removed for key biogeochemical variables,
  • and a mapped climatology of (ii) consisting of global 3D fields of the seawater distribution of CO2 chemistry and other parameters.

Analysis of GLODAPv2 parameters will allow for quantitative assessment of biogeochemical changes and feedbacks between climate change and the ocean system.
GLODAPv2 is the result of a multi-year global team effort funded by EU-IP CARBOCHANGE, US NSF, US-NASA, US DOE, the SCOR-IOC International Ocean Carbon Coordination Project (IOCCP) and many other projects, programs and organizations.
