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.

We would like to inform you that the LDEO Database Version 2018 (LDEO_Database_V2018) was published at the Ocean Carbon Data System (OCADS) - a data management project within the US NOAA National Centers for Environmental Information (NCEI). Approximately 13.5 million measurements of surface water pCO₂ made over the global oceans during 1957-2018 have been processed to make a uniform data file in this Version 2018. Measurements made in open oceans as well as in coastal waters are included. The data assembled include only those measured using equilibrator-CO₂ analyzer systems, and have been quality-controlled based upon the stability of the system performance, the reliability of calibrations for CO₂ analysis and the internal consistency of data.

The dataset is available from this link: https://www.nodc.noaa.gov/ocads/oceans/LDEO_Underway_Database/.

We would like to let you know that the consortium of the EU-Horizon 2020 funded project AtlantOS (“Optimizing and Enhancing the Integrated Atlantic Ocean Observing System“) and participants of the First International AtlantOS Symposium have released the Paris Declaration calling for an All-Atlantic Ocean Observing System that builds on cooperation through Galway and Belem Statements. The Declaration and the Symposium mark the transition from the EUHorizon 2020 Project AtlantOS to its development into the international All-Atlantic Ocean Observing System.  

The Symopsium, which took place on 25-28 March at the UNESCO Headquarters in Paris (France), was attended by scientists, policy makers, users, funders, the private sector and non-governmental organizations. The participants of this four-day long international meeting not only celebrated the success of four years of AtlantOS project work involving 62 partners from 18 countries and the investment of 20 million Euros, but also, presented a plan and ambition for the next decade of ocean observing in the Atlantic Ocean Basin to deliver on the needs of the Atlantic communities. 

We are very happy to inform you that the GLODAPv2_2019 data product has been released on March 26, 2019, during the First International AtlantOS Symposium in Paris. The Global Ocean Data Analysis Project (GLODAP) is a data synthesis activity of carbon-relevant ocean interior data by a consortium of international marine scientists. The EU project AtlantOS supported the new release, together with the IOCCP and numerous national funding bodies, universities and research institutes.

GLODAPv2_2019 is an incremental update of the GLODAPv2 data product released in 2016. Data from 116 new cruises have been added and small errors in the previous GLODAPv2 data product have been corrected. GLODAPv2_2019 contains data from 840 cruises with more than 1.1 million Niskin bottle sample analyses covering all oceans from 1972 through 2017.

We would like to let you know that following its 20^th Annual Meeting, held in Mindelo, Cabo Verde, in January 2019, the Partnership for Observation of the Global Ocean (POGO) has issued the Cabo Verde Declaration on Ocean Observations. In this Statement, the Directors of around 40 major oceanographic institutions call, in unison, on Governments worldwide to provide sustained support for ocean observations through a fully operational Global Ocean Observing System (GOOS). The Statement highlights the societal benefits derived from ocean observations and emphasises the currently insufficient resources available for international coordination for the scale of the work that is required as well as the need for full engagement of the developing world.
