Request review of manual for real-time quality control of pH data observations: a guide to quality control and quality assurance for pH observations

The U.S. IOOS QARTOD project (https://ioos.noaa.gov/project/qartod/) has initiated the development of a Manual for Real-Time Quality Control of pH Data Observations: A Guide to Quality Control and Quality Assurance for pH Observations in Coastal Oceans. The manual builds upon the existing twelve QARTOD manuals and the generous support from hundreds of contributors. They are unique in their focus on real-time QC, and are produced through an expanding series of reviews which ultimately result in a document that reflects present community thinking. They are living manuals, that are maintained and updated to ensure they remain accurate and relevant.

SOCAT version 2019 is released

SOCAT version 2019 was released on the 18th of June 2019, containing data submitted on or before 15th of January 2019. New data submissions are welcome at any time, and will be included in the next SOCAT release.

SOCAT data are released in versions. Each succeeding version contains new data sets as well as updates of older ones. The first version of SOCAT was released in 2011, the second and third version followed biennially. Automation allowed annual public releases since version 4. The latest SOCAT version (version 2019) has 25.7 million observations from 1957 to 2019 for the global oceans and coastal seas. Calibrated sensor data are also available.

Oregon’s draft ocean acidification & hypoxia action plan

This OAH Action Plan was developed in recognition of the OAH impacts that we see today, in the hopes of minimizing the impacts for tomorrow, and altering the trajectory of ocean changes for future generations. Because Oregon is one of the first states to feel the impacts of OAH, it is our intent that the OAH Action Plan will contain actions that are meaningful locally, and in fighting the global challenges of climate and ocean changes.  Additionally, the Action Plan will serve as a model for others to apply to their own geographical and political context. Once adopted by Governor Brown, the Action Plan will guide Oregon’s efforts and become Oregon’s submission to the International Alliance to Combat Ocean Acidification, and thus will be shared with the region and world.

Request for community feedback: practical guidelines for ocean acidification research

A group of 15 scientists from 7 countries, IOC-UNESCO, and the IAEA met at the IAEA Environment Laboratories in Monaco on 29-31 May 2019 to discuss practical guidelines for ocean acidification monitoring and experimental studies. The meeting was organized by the IAEA Ocean Acidification International Coordination Centre (OA-ICC) in partnership with the Global Ocean Acidification Observing Network (GOA-ON) and The Ocean Foundation. During this meeting, the participants worked on a list of tools useful for “GOA-ON in a Box” users and those starting ocean acidification research. The plan is to release these resources as a package for the community.

Requests for proposals: blue carbon restoration in Latin America and the Caribbean

The Ocean Foundation (TOF) is seeking multi-year proposals under the Ocean Acidification Monitoring and Mitigation (OAMM) project for blue carbon restoration (seagrass, mangrove, or salt marsh) in the Latin American and Caribbean Region.

TOF will fund one proposal for the region with a budget not to exceed US $90,000. TOF is soliciting multiple proposals which will then be reviewed by an expert panel for selection. Projects must be focused in one of the following four countries: Colombia, Ecuador, Jamaica, or Panama and must be coordinated with ocean acidification monitoring projects recently funded in these same countries by TOF. Proposals are due by June 30th, 2019. Decisions will be communicated by July 15th, 2019 for work to commence no later than August 15th, 2019.

Help share information and collaborate on ocean acidification research!

Would you like to know about on-going and planned ocean acidification research activities? Would you like to promote others to work with you?

One of the goals of the Ocean Acidification International Coordination Centre (OA-ICC) is to promote collaborative research projects, such as joint experiments and access to research facilities. To this end, the OA-ICC is looking to compile a list of ongoing and planned research projects on ocean acidification where there is a possibility for other researchers to participate. The list will be shared online to promote information exchange and collaboration.

To contribute to this effort, please send an email including the information below to:

Lina Hansson & Marine Lebrec, OA-ICC Project Office, IAEA Environment laboratories (oaicc(at)iaea.org)

Information needed:

  • location
  • contact (name, institute, email)
  • brief research focus
  • potential collaborator focus
  • start date
  • end date
  • web link (if available)

Acid–base physiology over tidal periods in the mussel Mytilus edulis: size and temperature are more influential than seawater pH

Ocean acidification (OA) studies to date have typically used stable open-ocean pH and CO2 values to predict the physiological responses of intertidal species to future climate scenarios, with few studies accounting for natural fluctuations of abiotic conditions or the alternating periods of emersion and immersion routinely experienced during tidal cycles. Here, we determine seawater carbonate chemistry and the corresponding in situ haemolymph acid–base responses over real time for two populations of mussel (Mytilus edulis) during tidal cycles, demonstrating that intertidal mussels experience daily acidosis during emersion. Using these field data to parameterize experimental work we demonstrate that air temperature and mussel size strongly influence this acidosis, with larger mussels at higher temperatures experiencing greater acidosis. There was a small interactive effect of prior immersion in OA conditions (pHNBS 7.7/pCO2 930 µatm) such that the haemolymph pH measured at the start of emersion was lower in large mussels exposed to OA. Critically, the acidosis induced in mussels during emersion in situ was greater (ΔpH approximately 0.8 units) than that induced by experimental OA (ΔpH approximately 0.1 units). Understanding how environmental fluctuations influence physiology under current scenarios is critical to our ability to predict the responses of key marine biota to future environmental changes.
