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.
