The SOLAS-IMBER Working Group on Ocean Acidification (SIOA) is pleased to announce that the 5^th International Symposium on the Ocean in a High-CO₂ World will be held in Lima, Peru on 7-10 September 2020. The lead organizers are Drs. Wilmer Carbajal (Pedro Ruiz Gallo National University, Peru) and Michelle Graco (Institute of the Sea of Peru, IMARPE) and colleagues, based on their successful bid that was submitted to the SIOA. The previous symposia in this series were held in Paris in 2004, Monaco in 2008, Monterey in 2012, and Hobart in 2016, each proving to be essential for the international, multidisciplinary community of researchers studying ocean acidification. The same is expected for this 5^th symposium, the first to be held in South America.

Please save the dates! More detailed information will soon be available from the organizers.

 We are excited to let you know that our colleagues Dennis Pierrot (NOAA-AOML/Univ. Miami-CIMAS, USA) and Tobias Steinhoff (GEOMAR, Germany) have just produced a manual that is intended to help guide the community on the “Installation of autonomous underway pCO₂ instruments onboard ships of opportunity.” The manual is full of good tips based on real experience from the authors and several other members of the community. The information contained in this technical document pertains specifically to the installation of the system built by General Oceanics, Inc. in Miami, Florida. However, most of the instructions and issues discussed should apply to any type of autonomous system. Different sections of the manual describe the different phases of the installation process, from hardware requirements and necessary preparations to the installation and testing of the system.

You can download the document from the IOCCP site HERE. Please cite the document as: Pierrot, D., and T. Steinhoff, 2019: Installation of autonomous underway pCO₂ instruments onboard ships of opportunity. NOAA Technical Report, OAR-AOML-50 (doi:10.25923/ffz6-0x48), 31 pp.

We would like to inform you about an upcoming webinar on "The Ocean Acidification Data Stewardship (OADS) and the Ocean Carbon Data System (OCADS) projects" organized as part of the MACAN (US Mid-Atlantic Coastal Acidification Network) webinar series. The event will be held on Wednesday, May 8, 2019, 6:00 PM – 7:00 PM CEST. During the webinar, Liqing Jiang, a chemical oceanographer at NOAA/National Centers for Environmental Information (NCEI) and Associate Research Scientist at University of Maryland will discuss two data management projects residing at NCEI: OADS and OCADS. OADS features rich metadata management and covers all types of ocean acidification data, including chemical, biological & model output. OCADS focuses on inorganic ocean carbon data and serves data producers from the entire international ocean carbon community.

If you're interested, please register for the webinar HERE.

On behalf of the Global Ocean Acidification Observing Network (GOA-ON) we are excited to announce that the GOA-ON Implementation Strategy was officially launched at the 4^th GOA-ON International Workshop, held in Hangzhou, China on 14-17 April. This document outlines how to implement the GOA-ON Requirements and Governance Plan, including expanding ocean acidification observations, closing human and technology capacity gaps, connecting scientists regionally and globally, and informing about the impacts of ocean acidification. The aim is to provide guidance that will allow for comparability across the Network, while considering the potentially different requirements and impediments of regions. The Implementation Strategy also offers practical information prompting members to approach GOA-ON’s goals.

The Implementation Strategy can be found on the GOA-ON website HERE. The GOA-ON Executive Council welcomes any feedback you may have about this document by 1 July 2019. You may provide feedback by contacting Jan Newton (janewton[at]uw.edu) and the GOA-ON Secretariat (secretariat[at]goa-on.org) directly.

Six SCOR working group proposals that have been submitted to the SCOR Secretariat for consideration at the 2019 SCOR Annual Meeting are available on the SCOR Web site. The Executive Committee will be very grateful for comments from SCOR National Committees, individuals, and interested organizations to assist in the review of these proposals. SCOR WG proposal reviews are due to Ed Urban, Executive Director of SCOR, before 15 August 2019. Decisions on which group(s) will be funded will be made at the SCOR annual meeting on 23-25 September 2019 in Toyama, Japan.

We would like to let you know that registration is open for the 2019 US Ocean Carbon & Biogeochemistry (OCB) Summer Workshop which will be held June 24-27 in Woods Hole, MA, USA. You can see the list of plenary sessions with their descriptions and lists of speakers HERE. Presentations and recordings from previous OCB Summer Workshops are available on OCB archive at: https://www.us-ocb.org/summer-workshops/.

There is a registration fee for participating in the OCB Summer Workshop. The workshop will be capped at 180 participants due to space constraints. Registration will close either when this limit is reached or on May 24, whichever comes first. A wait list will then be started. Please plan accordingly and register on time. Fewer than 50 spots remain!

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.
