As another attempt to achieve uniformity in nomenclature amongst various ship-based observing efforts globally, attached please find a memo from the IOCCP Scientific Steering Group and the Joint Technical Commission for Oceanography and Marine Meteorology (JCOMM) Ship Observations Team (SOT) Executive Panel providing guidance on appropriate naming of our scientific activities on ships. In particular the underway pCO₂ measurements.

We would like to let you know about the upcoming Sea-Bird Scientific live webinar on "Ocean Acidification: High-Frequency Long-Term measurements of pH and Deployment Best Practices," which will take place on Thursday, 18 July, at 17:00 UTC. During the webinar, Charles Branham, Ph.D. will cover technical information and advantages of using ISFET pH sensors. Greg Ikeda will talk about best practices for deploying and maintaining the SeaFET V2 and SeapHOx V2, two moored ISFET pH sensors offered by Sea-Bird Scientific. To register for the event, and to read more about the webinar and the speakers, please see here: https://www.seabird.com/webinar_pH

We would like to inform you about the release of version 2019 of the Surface Ocean CO₂ Atlas (previously known as version 7). The Surface Ocean CO₂ Atlas (SOCAT) documents the increase in surface ocean CO₂, a critical measure as the oceans are taking up one quarter of the global CO₂ emissions from human activity. SOCAT version 2019 has 25.7 million quality-controlled surface ocean fCO₂ (fugacity of CO₂) observations from 1957 to 2019 for the global oceans and coastal seas. SOCAT is a community effort with more than 100 contributors worldwide.

We would like to announce the release of a new, fully open source tool, which was designed to ease the Level 1 quality control of hydrographic cruise bottle data before submitting it to the data centres. The tool was developed under the H2020 AtlantOS project. The use of AtlantOS Ocean Data QC is fully multi-platform as installers are provided for Windows, MacOS and several Linux distributions. Visit the GitHub page (https://github.com/ocean-data-qc/ocean-data-qc) to install the tool, view the demo, find out about the details, or post comments on issues/wishes for future releases.

We would like to let you know about today's Global Ocean Observing System (GOOS) webinar on OceanGliders scheduled for 3 June, at 14:00 UTC/GMT. The webinar will be presented by Brad deYoung (Memorial University of Newfoundland, Canada) and Pierre Testor (Laboratoire d'Oceanographie et du Climat, France).

We would like to let you know that the SCOR Working Group 149 on "Changing Ocean Biological Systems (COBS)" has launched a new tool used for running best practice experiments in ocean research. The new tool is called MEDDLE: The Multiple Environmental Driver Design Lab for Experiments, and includes learning material/ videos, an experimental design tool to help scientists create accurate and statistically meaningful single and multi-driver experiments, and a simulator that allows users to run several virtual laboratory experiments by setting the combined levels of the drivers, choosing the number of replicates, and considering natural variability. 

You can find more information about MEDDLE from the dedicated website: https://meddle-scor149.org/, which includes a handbook on using MEDDLE.

We are happy to let you know that the Global Ocean Observing System (GOOS) has launched its 2030 Strategy during the recent 1^st Global Planning Meeting of the UN Decade of Ocean Science for Sustainable Development, held 13-15 May in Copenhagen, Denmark. The need for expansion of a global ocean observing system, designed to meet the requirements of a broad suite of users, is clear and urgent. The Global Ocean Observing System 2030 Strategy identifies a vision for a truly integrated global ocean observing system that delivers the essential information needed for our sustainable development, safety, well-being and prosperity. The vision presented in the Strategy cannot be achieved by GOOS alone. GOOS will lead the ocean observing community and create the partnerships to grow an integrated, responsive and sustained observing system. The Strategy identifies objectives to deepen engagement and impact, improve system integration and delivery, and build for the future.

IOCCP as GOOS Biogeochemistry Panel is fully committed to being part of the community-wide effort to make this vision a reality.

We encourage you to take a look at the OceanObs'19 Conference first circular which provides a preview of the daily conference program. The Conference will take place 16-20 September 2019, at the Hawaii Convention Center, Honolulu, HI, USA. The event will gather 1200 people from 60 nations, hold 50 exhibits, art, entertainment, and more. OceanObs’19 will determine how we meet future user needs (information), improve the delivery of products across the globe (interoperability), advance technology and services (innovation), and balance needs, capabilities, and knowledge worldwide (integration). Achieving these outcomes will result in a fit-for-purpose Global Ocean Observing System over the next decade.

Please also note that due to overwhelming interest, the poster deadline has been extended to June 27, 2019. Stay tuned for further updates by following #OceanObs19 on Twitter or check the Conference website: http://www.oceanobs19.net/ 

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.
