We would like to let you know that an updated version of Jena CarboScope ocean CO₂ flux product can be accessed from the website at http://www.bgc-jena.mpg.de/CarboScope/?ID=oc_v2021. CarboScope provides the temporally and spatially resolved estimates of the global sea-air CO₂ flux based on the SOCAT data set of pCO₂ observations, as presented in Rödenbeck et al., 2013. The product comprises seasonal, interannual, and day-to-day variations. This update involves the use of SOCATv2021 data and the additional year 2020.

On behalf of the event organizers, we invite you to join the OASIS for a Predicted Ocean, a UN Ocean Decade Laboratory Satellite Event held on Thursday, September 16 during two identical one-hour sessions at 14:00 UTC and 23:00 UTC. This online workshop will bring the air-sea observation community together to discuss how we can contribute to Observing Air-Sea Interactions Strategy (OASIS) themes to make OASIS goals a reality. The Satellite Activity will encourage brainstorming and collaborations using short pre-recorded talks combined with highly interactive online tools. We will use Gather.Town with separate rooms for each theme, whiteboards, a poster session room, small meeting areas, and a larger plenary session. Don’t miss your chance to help launch the OASIS for a Predicted Ocean.

Please register for this workshop at no cost at the following link: https://airtable.com/shreC0mGhtDDUiz2O See below for more information on the themed poster sessions and events timetable.

On behalf of the Global Ocean Acidification Observing Network (GOA-ON) we would like to let you know that the Ocean Acidification Week 2021 is just around the corner (Monday 13 September - Friday 17 September, 2021). This year, GOA-ON's virtual OA Week includes 5 plenary sessions, updates from each regional hub, and many community discussion sessions. The full program can be viewed from here.

Please visit the OA Week 2021 webpage for more details about each virtual session, and to register. Feel free to share the webpage and full program with your professional networks.

We are happy to let you know that the Ocean Observing System Report Card for 2021 was released in July by the GOOS Observations Coordination Group. Each year this Report provides a key insight into the status of the Global Ocean Observing System, assessing observing networks’ progress, focusing on what is needed to meet the challenges and demands for ocean information, and encouraging collaborations and new partners to join the ocean observing community.

The 2021 Report features several key areas including a section on the status and value of monitoring ocean oxygen and deoxygenation to which IOCCP and the Global Ocean Oxygen Network (GO₂NE) among others have contributed. The 2021 Report Card can be viewed online or downloaded as PDF from www.ocean-ops.org/reportcard2021

On behalf of the GLODAP Reference Group, and hundreds of seagoing oceanographers that tirelessly have collected data all over the ocean, we are happy to announce the publication of GLODAPv2.2021. The Global Ocean Data Analysis Project (GLODAP) data product provides access to quality controlled surface to bottom ocean biogeochemical data, with an emphasis on seawater inorganic carbon. GLODAPv2.2021 is an update of the previous version, with 43 additional cruises, extension of time coverage until 2020, and the inclusion of DOIs for each individual cruise. GLODAPv2.2021 includes measurements from more than 1.3 million water samples from the global oceans collected on 989 cruises. The data for the 12 core variables have undergone extensive quality control, especially systematic evaluation of bias. The data are available in two formats: (i) as submitted by the data originator but updated to WOCE exchange format and (ii) as a merged data product with adjustments applied to minimize bias. 

The original data, their documentation and doi codes are available at the Ocean Carbon Data System of NOAA NCEI. This site also provides access to the merged data product, which is provided as a single global file and as four regional ones. An accompanying manuscript has been submitted for consideration for publication in Earth System Science Data: https://essd.copernicus.org/preprints/essd-2021-234/. See also the GLODAPv2.2021 release poster.

We would like to let you know that the next presentation in the GOA-ON Webinar Series will take place on Wednesday, 14 July 2021 at 10:00 Australian Eastern Standard Time (UTC +10). The speaker will be Dr. Eric Mortenson, a postdoctoral researcher at CSIRO, Australia. His talk is entitled, "Regional changes in Southern Ocean biogeochemistry due to projected carbon uptake". Please register here: https://register.gotowebinar.com/rt/3191371397724780304

If you missed any of the GOA-ON webinars, you can watch them on the GOA-ON Youtube Channel. Most recently, we heard from Dr. Mohammed Idrissi, Dr. Melissa Chierici, and Dr. Chibo Chikwililwa who discussed ocean acidification monitoring across western Africa.

We are delighted to announce the publication of “A vision for FAIR ocean data products” in Nature Communications authored by the GLobal Ocean Data Analysis Project (GLODAP) Reference Group Co-Chairs Toste Tanhua (GEOMAR, Germany) and Siv Lauvset (NORCE, Norway) and others, including several current and former members of the IOCCP Scientific Steering Group.

The paper, informally known as the GLODAP Manifesto, highlights the critical role which the co-located high-quality measurements of physical and biogeochemical parameters collated in GLODAP play in quantifying and monitoring the ocean cycles of carbon and related biogeochemical EOVs, and thus informing the stakeholders (e.g. the IPCC assessments, the Global Climate Observing System indicators) on several critical processes. Making GLODAP fully FAIR (findable, accessible, interoperable, and reusable) requires substantial upgrades to the existing data extraction system to benefit various users and their growing needs. Recognizing that GLODAP, just like SOCAT and other ocean data synthesis products, remains a largely unfunded, community effort, the paper calls for building and supporting a sustained infrastructure and associated resources to ensure that GLODAP continues to provide the global community with a unique service, the importance of which will only increase as we step up our climate mitigation and adaptation efforts.

The paper is available in open access from here. It can be cited as:

We are excited to announce the release of Surface Ocean CO₂ Atlas (SOCAT) version 2021 which is now available via www.socat.info. SOCAT documents the increase in surface ocean CO₂ for the global oceans and coastal seas. Quantification of the global ocean CO₂ uptake to better than 0.2 Pg C yr-1 requires an accuracy of < 2 μatm for in situ surface ocean fCO₂ (fugacity of CO₂) measurements. Quality-controlled, synthesis and gridded products in SOCAT version 2021 contain 30.6 million in situ surface ocean fCO₂ measurements with an estimated accuracy of < 5 μatm. A further 2.1 million fCO₂ values with an accuracy of < 10 μatm are also available. Data collection has continued during the pandemic, albeit at a reduced rate.
