Global Methane Budget 2020 published
Monday, 03 August 2020
We are pleased to inform you that the Global Carbon Project (GCP) has published an updated and expanded Global Methane Budget. For the decade of 2008-2017, global emissions of methane are 576 (550-594) Tg CH4 per year as estimated from atmospheric inversions (top-down approach). The global CH4 sink is 556 Tg (501-574) CH4 per year. The source–sink mismatch reflects, and is consistent with, the observed average imbalance in the atmosphere of 13 Tg (0-49) CH4 per year (the CH4 growth rate). The sum of all sources as estimated from inventories and modeling (bottom-up approaches) is 737 (594-880) Tg CH4, significantly higher than estimated from the top-down approach and reflecting the compounded uncertainties of the multiple CH4 sources.
The effort was supported by 91 contributors and 69 research organizations. Please find papers, data and additional resources at: https://www.globalcarbonproject.org/methanebudget
GLODAPv2.2020 product released!
Monday, 29 June 2020
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 GLODAPv2.2020.
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. GLODAPv2.2020 is an update of the previous version, with 106 additional cruises, extension of time coverage until 2019, and the inclusion of available discrete fCO2 values in the merged product files. GLODAPv2.2020 includes measurements from more than 1.2 million water samples from the global ocean collected on 946 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 (OCADS) 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. For a more detailed summary of the product see the attached poster.
The continuous work to regularly update and refine GLODAP is a priority for IOCCP, and we are happy to support this effort.
Surface Ocean CO2 Atlas (SOCAT) version 2020 is now available!
Thursday, 18 June 2020
On behalf more than 100 contributing scientists worldwide, we proudly announce the release of 2020 version of the Surface Ocean CO2 Atlas (SOCAT, www.socat.info) which is a synthesis activity with annual public releases prepared by international marine carbon scientists. SOCAT version 2020 contains 28.2 million in situ surface ocean fCO2 (fugacity of CO2) measurements for the global ocean and coastal seas with an accuracy < 5 μatm, while a further 2.3 million fCO2 values with an accuracy of 5 to 10 μatm are made available separately. SOCAT documents the increase in surface ocean CO2 (carbon dioxide), a critical measure as the oceans are taking up one quarter of the global CO2 emissions from human activity.
The SOCAT community-led synthesis product is a key step in the value chain based on in situ inorganic carbon measurements of the oceans, which provides policy makers with essential information on ocean CO2 uptake in climate negotiations. The global need for accurate knowledge of ocean CO2 uptake and its variation makes sustained funding for in situ surface ocean CO2 observations imperative. The annual SOCAT release is a Voluntary Commitment for SDG 14.3 (#OceanAction20464) and contributes to the UN Decade of Ocean Science for Sustainable Development. The poster handout has further details on 2020 version key features, findings and other information, including timeline for preparing the 2021 version.

OCB Working Group Webinar: Filling the gaps in observation-based estimates of air–sea carbon fluxes, Tuesday, May 5, 2020 @ 15:00–20:00 UTC
Monday, 04 May 2020
We would like to let you know that the first meeting of the US Ocean Carbon & Biogeochemistry (OCB) Working Group on "Filling the gaps in observation-based estimates of air–sea carbon fluxes" will take place this week, May 5-6, 2020 via Webex. The first day of the meeting (May 5) is open to everyone and will include presentations on the current state of understanding of the global ocean carbon sink. If you're interested, please register in advance HERE. After you submit your registration, Webex will send you an invitation with connection information, including a phone number if you prefer telephone audio. You can visit the working group website to view the meeting agenda. The presentations on May 5 will be recorded and posted on the OCB YouTube channel for viewing later. All webinar attendees will be muted, but you can type in questions and participate in discussion via the Q&A function as time allows at the end of each block of talks.
This working group was assembled in 2019 to assess critical uncertainties in existing observation-based air-sea carbon fluxes, determine how best to integrate observation-based open-ocean and coastal-ocean CO2 air–sea fluxes, and quantify uncertainties in the natural (pre-industrial) outgassing of CO2. These efforts will lead to better constraints on the contemporary ocean carbon sink and its variability. The results of this OCB Working Group will assist the global carbon community in understanding the state of the global carbon cycle so as to contribute to international efforts to address climate change.
