Ocean acidification research creates waves

Dr Chris Cornwall’s research on ocean acidification was recently published in the ICES Journal of Marine Science and was the focus of a highlight in Nature. He explains:

Ocean acidification is the increased absorption of anthropogenically derived CO2, and it has the potential to impact many marine ecosystems. At particular risk from ocean acidification are organisms that precipitate calcium carbonate, such as corals, shellfish and many forms of seaweed and phytoplankton for example. However, ocean acidification research is logistically and theoretically complex.

The research was done in conjunction with Associate Professor Hurd from the Institute for Marine and Antarctic Studies (IMAS) at the University of Tasmania. We examined components of methods used in 465 past studies on ocean acidification. We highlighted that the chemical methods used in ocean acidification research has improved since the publication of set guidelines in 2010, but randomisation and the number of experimental units used has not. We hope that this paper will be used by the research community as a positive tool to improve future work, as we highlight many solutions to commonly encountered problems.
