Ocean acidification blog: 2012 in review

Dear Blog Addicts,

Lina Hansson and I wish all the best for 2013 to all readers of the EPOCA blog! We thank you all for your interest. Even though EPOCA came to an end in June 2012, we have been able to maintain this blog, partly thanks to support from the International Atomic Energy Agency (IAEA). The blog will soon be transferred to the Ocean Acidification International Coordination Centre and operated from IAEA. We hope that the transition will be smooth; stay tuned for more information.

Here are a few numbers:

  • 4584 posts have been published since 2006 (about 1198 in 2012)
  • 653 subscribers through RSS or email (up from 570 in 2011)
  • 376 Twitter followers (up from 270 in 2011)
  • an unknown number of FaceBook friends

The stats helper monkeys prepared a 2012 annual report for this blog: click here to see the complete report.

I remind you below the content of the “About” page and, also, that comments are always welcome. Just type your comment in the box located below each article. Note that comments are moderated.

This blog was started in July 2006 as a “one man” effort. It is a product of EPOCA, the European Project on Ocean Acidification since May 2008 and it is sponsored by the IMBER and SOLAS projects since January 2010. Its only ambition is to centralize information available on ocean acidification and its consequences on marine organisms and ecosystems. By no means it is meant to be comprehensive but we are trying to provide an unbiased view of the literature and media articles. The owner of this blog, the European Commission and the sponsoring organizations do not endorse the information published.

This blog is coordinated by:

Ocean Acidification Presentation and Roundtable Discussion – Jan. 9, 2012

Acclaimed University of Alaska Fairbanks researcher Jeremy Mathis will be in Dillingham on January 9th, 2012.  He will be presenting his research findings on ocean acidification and moderators will lead a discussion with the community on what the changing oceans mean for a fishing community such as Dillingham.

SOLAS-IMBER Ocean Acidification working group just launched

SOLAS and IMBER have launched, in September 2009, a working group on Ocean Acidification. It is sub-group 3 of the IMBER/SOLAS Carbon Research Working Group (SIC!).

The tasks of this group are:

  1. Coordinate international research efforts in ocean acidification
  2. Undertake synthesis activities in ocean acidification at the international level

Global warming tactic cools climate but won’t help corals, say Stanford researchers

“Geoengineering” experiments proposed to reduce global warming by blocking sunlight with atmosphere-injected particles may cool the world but still leave carbon dioxide levels dangerously high, Stanford scientists say.

Sunlight-blocking particles would fail to solve the problems of ocean acidification and dying corals, two significant repercussions of climate change, according to a study by Ken Caldeira of Stanford University and the Carnegie Institution, Damon Matthews of Concordia University, and Long Cao of the Carnegie Institution. Atmospheric carbon dioxide dissolves in ocean water, making it more acidic and difficult for animals to build their shells or skeletons, especially corals.

Call for input on the OCB response to EPA’s Notice of Data Availability (NODA) on ocean acidification

If you are interested in commenting on the first draft, then please download the document (here) particularly focussing on points 4-6 and returning to Heather Benway by 7th June 2009.

More information on Solas web site.

Documents about the latest knowledge on Ocean Acidification

IOC, SCOR, IGBP and IAEA have recently produced a number of documents about the latest knowledge on Ocean Acidification and priorities for future research, as a result of the Second Symposium on the Ocean in a High-CO2 World in October 2008. The publications are all available on the following website and involve a large number of international experts.

OCB Ocean Acidification Subcommittee coordinates input to EPA Federal register notice on ocean acidification

The Ocean Carbon and Biogeochemistry Program Ocean Acidification Subcommittee is currently discussing how to coordinate and provide input to the recent EPA federal register notice on ocean acidification. If you would like to be involved, please contact OCB Ocean Acidification Subcommittee co-chairs Joan Kleypas ( and Richard Feely (
