The Integrated Carbon Observation System (ICOS) invites researchers and scientists from around the world to submit abstracts for oral and poster presentation at the 4th ICOS Science Conference in Utrecht, the Netherlands, on 15-17 September 2020. The conference welcomes abstract submissions following the overall topic Knowledge for shaping the future – understanding our Earth's biogeochemical processes in 8 themes, several of which consider measurements in the ocean and at the interface with land and atmosphere. For a detailed description of the themes, and to submit your abstracts, visit https://www.icos-ri.eu/sc2020/themes. 

The abstract submission closes on the 19th of April 2020 (midnight UTC+2).

We would like to let you know that This email address is being protected from spambots. You need JavaScript enabled to view it. will accept proposals for new working groups from now until 17 April 2020. The guidelines, a template, and word limits are available at https://scor-int.org/work/groups/proposals/, including a PowerPoint presentation explaining the proposal process. Each proposal will be evaluated by national SCOR committees in terms of scientific merit and quality, timeliness, and achievability of the proposed terms of reference. National SCOR committees are an important aspect of SCOR’s operation and play a key role in reviewing working group proposals and in seeking new funds to support working group activities. In addition, the review of working group proposals is open worldwide to partner organizations and individuals who would like to provide comments.

The 2020 SCOR Annual Meeting will take place in Guayaquil, Ecuador on the week of the 19-23 of October 2020. Details about the meeting will be posted on the meeting website as they become available. Annual SCOR meetings are open, but anyone submitting a proposal or included in a proposed working group membership will be asked to leave the room when their proposal is discussed, to avoid any appearance of favoritism toward proposals that are represented at the meeting by a proponent. Please contact This email address is being protected from spambots. You need JavaScript enabled to view it. if you have any questions about the process for working group proposals.

The application window is now open for the next Nippon Foundation-POGO Centre of Excellence (NF-POGO CofE), which provides world class education and training in the field of observational oceanography. This is an intensive training course for young professionals at the post-graduate level, ten months in duration, with an intake of ten trainees per year. The course is sponsored by the Nippon Foundation and hosted by the Alfred Wegener Institute for Polar and Marine Research. It is conducted at AWI’s site on the offshore island of Helgoland with focus on open-ocean sciences and also at AWI’s site on the UNESCO reserve Waddensea island of Sylt where shelf/basin interactions are topics of study.

The call for applications will be open until the 15 March 2020. Successful candidates will be informed by end of June 2020, with training scheduled to begin in the second half of October. You can read more about what the training involves and submit an application here: https://www.awi.de/en/about-us/sites/helgoland/visiting-scientists/centre-of-excellence-nf-pogo.html 

We would like to draw your attention to the recent IUCN review report on "Ocean deoxygenation: Everyone's problem." This report is the largest peer-reviewed study so far into the causes, impacts and possible solutions to ocean deoxygenation. Ocean regions with low oxygen concentrations are expanding, with around 700 sites worldwide now affected by low oxygen conditions – up from only 45 in the 1960s. In the same period, the volume of anoxic waters – areas completely depleted of oxygen – in the global ocean has quadrupled, according to the report. The ocean is expected to lose 3–4% of its oxygen inventory globally by the year 2100 under a business-as-usual scenario, but the global average masks local changes that are predicted to be, for example, more severe in mid to high latitudes. Most of the losses are predicted to be concentrated in the upper 1000 m of the water column, which is richest in marine biodiversity. The full report and summary for policy makers are available from: https://www.iucn.org/theme/marine-and-polar/our-work/climate-change-and-oceans/ocean-deoxygenation

At the same time we would like to inform you about a related OceanObs'19 Community White Paper on "Multidisciplinary Observing in the World Ocean’s Oxygen Minimum Zone Regions: From Climate to Fish — The VOICE Initiative." The Variability of the Oxycline and its ImpaCt on the Ecosystem (VOICE; http://www.ioccp.org/voice) initiative, supported by IOCCP since its beginning in 2017, aims to demonstrate how societal benefits drive the need for integration and optimization of biological, biogeochemical, and physical components of regional ocean observing related to eastern boundary systems (EBSs). VOICE chose to focus on the upper oxycline (transition between high and low oxygen waters) which is fundamentally important for the ecosystem structure and can be a useful proxy for multiple observing objectives connected to EBSs that neighbour oxygen minimum zones. In this paper, we present a first readiness level assessment for ocean observing of the oxycline in EBS around the globe. The paper can be accessed openly and freely at: https://www.frontiersin.org/articles/10.3389/fmars.2019.00722/full 

This is to let you know that a new version of the AtlantOS Ocean Data QC software is available.
