We would like to let you know that the Intergovernmental Panel on Climate Change (IPCC) is inviting experts and governments to review the Second Order Draft of the Special Report on the Ocean and Cryosphere in a Changing Climate (SROCC). The review is open until 11 January 2019. Expert Reviewers can register with a self-declaration of expertise up to a week before the end of the review period. The report, to be finalized in the second half of 2019, follows the Special Report on Global Warming of 1.5ºC, which was released on 8 October. 

For those of you who are interested in calculating marine CO₂ system variables, we are happy to let you know that propagating uncertainty in these calculations just got easier. IAEA Ocean Acidification International Coordination Centre (OA-ICC) funded an effort to code a consistent set of tools in several public packages. Uncertainty propagation add-ons are now available for four of these packages: CO2SYS-Excel, CO2SYS-MATLAB, seacarb, and mocsy. Clicking on those links will lead you directly to the archive where each package can be downloaded, on CRAN for seacarb and on GitHub for the other 3 packages.  Links to the uncertainty propagation add-ons can also be found on our Standards and Methods site. A new publication detailing this effort, the tools, and interpretation of results is now available (Orr et al., 2018). The authors highlight, among other things, the use of a new error-space diagram to assess how propagated uncertainty changes with different input uncertainties. The paper also concludes that uncertainties from the constants often dominate propagated uncertainty, so that measurement uncertainty plays little role.

We would like to let you know that the Global Carbon Budget 2018 has now been published. Please see the Global Carbon Project website (http://www.globalcarbonproject.org) to access the highlights, paper, data, and a myriad of figures, infographics and videos related to the annual update of the global carbon budget and trends for the year 2017, and projections for 2018. You may also want to visit the Global Carbon Atlas http://www.globalcarbonatlas.org to explore in detail global and national CO₂ emissions.

We would like to let you know about the 18^th International Swiss Climate Summer School 2019 "Carbon and Climate in the Paris World: Getting out of the Fossil Fuel Carbon Budget Crunch" which will be held on 8 – 13 September 2019, in Ascona, Switzerland. The motivation for this highly interdisciplinary summer school is the current paradoxical situation wherein the internationally recognized warming targets of 2°C or even 1.5°C imply a tightly limited fossil fuel emission budget for the entire 21^st century, while the trends in the fossil fuel emissions suggest that this budget is consumed within the next one to three decades. With conventional mitigation and adaptation options not sufficiently exploited, humankind may need to deploy unconventional methods to meet its climate target. This summer school addresses Early Stage Researchers from the climate, engineering, social and economic sciences.

Application deadline: 11 January 2019.

We would like to inform you that the Second State of the Carbon Cycle Report (SOCCR2) was released by the U.S. Global Change Research Program (USGCRP) via https://carbon2018.globalchange.gov. With over 200 contributing experts, this interagency highly influential scientific assessment was led by the Carbon Cycle Interagency Working Group (CCIWG) and U.S. Carbon Cycle Science Program. Individual chapter PDFs can be downloaded HERE. Incorporating 19 chapters distributed across four interconnected sections (I. Synthesis, II. Human Dimensions of the Carbon Cycle, III. State of Air, Land, and Water, IV. Consequences and Ways Forward), SOCCR2 assesses the last decade of cross-sectoral carbon cycle advances across the U.S., Canada and Mexico, in the global context. The global community might also be interested in the 4^th U.S. National Climate Assessment which was released simultaneously via https://nca2018.globalchange.gov. 

We are happy to let you know that the 4^th Global Ocean Acidification Observing Network (GOA-ON) International Workshop (http://www.goa-on2019.com/en/index.html) will be held in Hangzhou, China from 14 to 17 April 2019. The Workshop, co-sponsored by IOCCP, will bring together scientists from around the world to discuss emerging aspects from the coupled effects of ocean acidification with multi-stressors, review global ocean acidification status and forecast capabilities, and explore opportunities for capacity development. The workshop is consisted of various events to facilitate an open, multi-level and comprehensive communication and exchanges among participants. There will be invited keynotes, selected oral presentations at plenary sessions, accepted oral presentations at parallel sessions, poster sessions, special events, and summaries organized in a three-and-a half day program. In addition, the Organizing Committee will host several activities to foster a relaxing atmosphere for participants, including ice-breaker, workshop banquet, and city tour by night. IOCCP is co-chairing the session on "Observing ocean and coastal acidification and the impacts on organisms and ecosystems", one of the four thematic sessions of the workshop.

Deadline for abstract submission is 10 January 2019. Travel grant award applications are due by 31 January 2019.

Ocean scientists, ocean observation specialists, industry representatives, service providers and users of ocean data & products from across the local, national & international operational oceanography community will gather in Halifax, Canada, for the GODAE OceanView Symposium, OceanPredict '19 (http://oceanpredict19.org/). The Symposium, aimed at advancing the science and application of ocean predictions, will take place on 6-10 May 2019. The event will present high-level speakers providing expert insight into the latest ocean research & development efforts, products and services and applications. OceanPredict'19 offers participants to engage in special science splinter meetings, poster sessions, booth exhibitions and discussions to explore and define the direction of future operational oceanography. As marine biogeochemistry observations are becoming increasingly needed to develop future ocean predictions, members of our community might be interested in contributing to one or more of the many themes selected for this symposium.

Abstract submission deadline: 7 December 2018.

The Global Ocean Acidification Observing Network (GOA-ON) and the Intergovernmental Oceanographic Commission (IOC) of UNESCO invite you to take part in a survey on ocean acidification research and observation data. Your answers to this survey will help trace where ocean acidification data is being collected, and where it is stored and served, to facilitate reporting on one of the indicators of Sustainable Development Goal (SDG) 14, 'Life below water'. SDG14 Target 3 on ocean acidification calls to 'minimize and address the impacts of ocean acidification, including through enhanced scientific cooperation at all levels'. IOC-UNESCO is the custodian agency for the Indicator 14.3.1, which is used to measure the progress made to achieve the target. With the support from GOA-ON, and other experts in the field of ocean acidification, IOC-UNESCO has developed the SDG Indicator 14.3.1 Methodology 'average marine acidity (pH) measured at agreed suite of representative sampling stations'. The Methodology provides the necessary guidance on which variables to report, how to conduct ocean acidification measurements and on how to report the collected information in a transparent and traceable manner.

You can take part in the survey by following the link HERE. Please submit your answers by December 20, 2018.

On behalf of an external review committee, we invite you to participate in a survey of the US GO-SHIP program. US GO-SHIP is an affiliate of international GO-SHIP, which performs global ship-based decadal surveys to collect, document, and store high precision and full depth hydrographic and biogeochemical data from the global ocean. The US CLIVAR and OCB programs are coordinating an external community review of US GO-SHIP to assess and provide feedback on program planning, progress, and opportunities to advance the scientific research of US CLIVAR and OCB.

This survey is one step of the process to collect community input. It is intended to gauge the effectiveness and value of US GO-SHIP operations, products and science and seeks to find opportunities to strengthen these in the future. We ask your input no matter your level of contact with US GO-SHIP, whether a casual observer and consumer of GO-SHIP data or science, a student who has gone on a cruise, a member of the Executive Committee, or anywhere in between. The survey will take 10-15 minutes to complete. Please fill out the survey (https://www.surveymonkey.com/r/GO-SHIP) by December 7, 2018.
