In December 2018, IOCCP Director and SSG member Rik Wanninkhof took part in a community workshop on "Synthesis and intercomparison of ocean carbon uptake in CMIP6 models." The workshop organized by US Ocean Carbon & Biogeochemistry (OCB) was held on December 8-9, 2018 in Washington, DC, USA, just before the Fall 2018 American Geophysical Union (AGU) Meeting. This activity complemented existing coordination of European modeling centers by building lines of communication between the US observational and analysis communities and the various contributing modeling centers in the US (NASA/GISS, NCAR/CESM, and NOAA/GFDL), Canada (CCCMA), and Australia (CSIRO) in advance of the 6^th phase of the Coupled Model Intercomparison Project (CMIP), which will inform the International Panel on Climate Change (IPCC) 6^th Assessment.
