On behalf of more than 100 contributing scientists worldwide, we proudly announce the release of Version 6 of the Surface Ocean CO₂ Atlas (SOCAT). SOCAT (www.socat.info) is a synthesis activity by international marine carbon scientists with annual public releases. SOCAT version 6 has 23.4 million quality-controlled in situ surface ocean fCO₂ (fugacity of carbon dioxide) measurements from 1957 to 2017 for the global oceans and coastal seas, as well as additional calibrated sensor fCO₂ measurements. The poster handout has further details on version 6 key features, findings and other information.

Over the past decade marine sciences experience a surge in the volume of data from in-situ collection, satellite missions and earth system model simulations. Scientists are increasingly faced with the emerging challenge of analysing and synthesising collected data, which are often too big and complex to detect temporal (diurnal to decadal) and spatial (local to global) variability or secular trends using traditional statistical approaches. Greater than ever proportion of the community has turned to advanced statistical and machine learning methods to integrate, analyse and synthetize these multi-platform data. The utility of these methods has been demonstrated in many areas of Earth Science, and is now also becoming apparent in ocean physics, air-sea interactions, ocean biogeochemical cycles, and marine ecology. This has resulted in the proliferation of data products that straddle oceanography and data science.

We invite scientists in this exciting intersection to submit abstracts for the session titled: "Novel data-analysis techniques for big data applications in marine science" (OS034). The session is open for submissions in the field of ocean physics, chemistry and/or biology but also those connecting the spheres, such as air-sea and air-land interactions.

We would like to let you know that an international conference on glider data management "Connecting glider data flows in Europe and beyond" will be held on 18-20 September 2018, at the Aquario du Genova, in Genoa, Italy. This meeting intends to open a 2.5 days forum dedicated to glider data management issues. Initiated by the EuroGOOS Glider Task team and aligned with the objectives of the GOOS-endorsed program OceanGliders, it will focus on technical and strategic issues related to the Everyone's Gliding Observatories (EGO) format and real time/delayed mode, and physical as well as biogeochemical gliders data management. Particular attention will be paid on discussions and provision of guidance on data management to the new glider teams willing to contribute to the global ocean observing system. A workshop session dedicated to the installation of the data management capacity in your institution is planned. The organization of this session is at the moment an option and will depend on the number of interested persons.

To attend the meeting, please fill in the registration form. Event registration must be completed at least one month prior to the event.

In view of the launching of the United Nations Decade of Ocean Science for Sustainable Development (2021–2030), the Ocean and Climate Platform and IOC-UNESCO are organizing a High Level Scientific Conference on 10 and 11 September 2018, at UNESCO Headquarters in Paris. The conference aims at synthesizing recent scientific progress on ocean and climate interplays; evaluating the latest ocean-climate trends within the context of increased ocean action; and reflecting on ways to move "from science to action". Organized around four sessions, the event will bring together scientists from multiple disciplines, civil society, businesses, decision-makers and UN entities, to share their expertise on ocean and climate related issues.

We would like to inform you that Ocean Acidification has been considered as one of World Meteorological Organization's Global Climate Indicators - a set of seven parameters that describe the changing climate without reducing climate change to only temperature. They comprise key information for the most relevant domains of climate change: temperature and energy, atmospheric composition, ocean and water as well as the cryosphere. These Global Climate Indicators have been identified by scientists and communication specialists in a discursive process led by GCOS during workshops and scientific panel meetings and have been finally endorsed by WMO. They form the basis of the annual WMO Statement of the State of the Global Climate, which is submitted to the Conference of Parties of the United Nations Framework Convention on Climate Change (UNFCCC).

This is to inform you that the Expert Review of the First Order Draft of the Intergovernmental Panel on Climate Change (IPCC) Special Report on the Ocean and Cryosphere in a Changing Climate (SROCC) will take place from 4 May until 29 June 2018. Expert Reviewers can register at www.ipcc.ch/apps/comments/srocc/fod/register.php up to a week before the end of the review period, until 22 June 2018, 23:59 (CST). The Expert Review of the First Order Draft is a key element of the IPCC assessment process. Experts from around the world will offer comments and suggestions to the author teams. The report authors address every comment received when they prepare the next draft, and the review process aims to include the broadest possible scientific perspective.

We would like to let you know that abstract submission will soon close for the 3^rd Integrated Carbon Observation System (ICOS) Science Conference to be held on 11-13 September 2018 in Prague, Czech Republic. The Conference welcomes abstracts within 14 themes in biogases and cycles research (see below for details). Contributions from commercial companies are welcome, but with the restriction that the presenting and/or first author of an oral presentation or posters cannot be affiliated to a commercial company.

Extended deadline: 18 May 2018 at 12:00 (UTC+2)

We would like to let you know that applications are now open for the 2018 Galápagos Ocean Acidification Summer School which we have informed you about in our latest issue of the IOCCP Conveyor. The course will be held at the Charles Darwin Research Station, Puerto Ayora, Galápagos, Ecuador on 19-28 August 2018. The course is co-organized by IOCCP SSG member and 2018 SCOR Visiting Scholar Cristian Vargas. The aim of the course is to use natural CO₂ gradients around Roca Redonda volcanic CO₂ vent site to conduct in situ observations using a wide range of techniques for long-term capacity building (chemistry, biology, geology, etc) and data collection. This will be an advanced training course with a combination of theoretical training and field expedition. 

The deadline for applications is 4 June 2018. To apply, please fill out the attached application form and send it to the course organizers together with a letter of intention and a CV. For more information on the course objectives, target participants, lecturers and organizers, please see the attached course flyer. 

On 25 April, the European Ocean Observing System (EOOS) stakeholder consultation is launched to collect feedback on the draft strategy and implementation plan for 2018-2022. EOOS is a coordinating framework designed to align and integrate Europe's ocean observing capacity in the long-term; to promote a systematic and collaborative approach to collecting sustained information on the state and variability of our seas; and to underpin sustainable management of the marine environment and its resources. Stakeholder co-design and engagement are key to developing EOOS as a truly integrated and sustained ocean observing framework. The benefits of EOOS will likely span world-wide as its vision, guiding principles and proposed implementation framework are complementary to those of the Global Ocean Observing System (GOOS). Therefore, we encourage the global marine biogeochemistry observationalist community to become part of this consultation process. 

The survey will close on 15 June 2018. To read the EOOS draft strategy and implementation plan and submit your feedback please go to the consultation page: http://www.eoos-ocean.eu/consultation-2018/. 

We would like to let you know that applications are now open to attend a community workshop on "Synthesis and intercomparison of ocean carbon uptake in CMIP6 models." The workshop organized by US Ocean Carbon & Biogeochemistry (OCB) will be held December 8-9, 2018 in Washington, DC, USA, just before the Fall 2018 American Geophysical Union (AGU) Meeting. Climate and Earth System Modeling Centers around the world are currently preparing their state of the art models to participate in the 6^th phase of the Coupled Model Intercomparison Project (CMIP), which will inform the International Panel on Climate Change (IPCC) 6^th Assessment. Each center is planning to perform ocean carbon experiments in the boreal spring/summer/fall 2018 time frame. This activity will complement existing coordination of European modeling centers by building lines of communication between the US observational and analysis communities and the various contributing modeling centers in the US (NASA/GISS, NCAR/CESM, and NOAA/GFDL), Canada (CCCMA), and Australia (CSIRO). The organizers plan on reserving ~20% for attendees to be in early career (PhD - tenure track) stage.
