Description of the workshop

The Surface Ocean CO2 Atlas (SOCAT) is an activity by the international marine carbon research community. It aims to improve access to surface water CO2 data by regular releases of quality controlled, synthesis and gridded fCO2 (fugacity of carbon dioxide, similar to partial pressure) data products for the global oceans and coastal seas. SOCAT version 2, public since June 2013, contains 10.1 million surface water fCO2 data from 2660 data sets between 1968 and 2011. Version 3 extends the data set to December 2013 and includes CO2 measurements from alternative sensors and platforms. Quality control for version 3 will be carried out in summer 2014. The automation system for data submission (for version 4) will be launched in 2014.

Key questions to be addressed include:

  • What is needed for efficient quality control (version 3)?
  • How does data submission via the automation system work?
  • Should SOCAT products include additional parameters (version 4)?
  • How do we promote SOCAT science?

The workshop will update the SOCAT community on recent progress, will welcome new members, will enable discussion of SOCAT strategy and will set the SOCAT agenda for the next 24 months. The workshop will contribute to efficient quality control and submission via the automated data submission system. The workshop will provide feedback on SOCAT strategy to the global and regional leads.
