Coral used to predict climate change effects (audio)

University of Queensland (UQ) researchers are planning to test whether the Great Barrier Reef will be able to recover from the effects of climate change.

The annual Great Barrier Reef coral mating season has begun and researchers on Heron Island off the Queensland coast are planning to capture coral sperm and eggs in order to subject them to different levels of carbon dioxide as they develop.

PhD student Alicia Lloyd from UQ’s Coral Reef Studies Centre says her team will collect coral eggs and sperm when the spawning begins to cross-fertilise with adult coral.

She says the aim is to grow coral in tanks with different levels of carbon dioxide and acidity.

Acidic seas threaten coral reefs

A volcanic crater that recently emerged in the Mediterranean Sea has made it possible to experiment on how corals will be affected as the oceans become more acidic from carbon dioxide.

An Italian group will present their preliminary findings in Wageningen, Netherlands at the “Reefs in a Changing Environment” symposium (13-17 December) organised by the International Society for Reef Studies.

Preliminary results show that corals exposed to lower pH levels suffer higher mortality than corals at current pH levels. Seawater worldwide is predicted to increase in acidity (decrease in pH) due to carbon dioxide emissions, which dissolve in water and cause acidity to rise.

New web site on benthic ocean acidification

What are the impacts of ocean acidification on key benthic (seabed) ecosystems, communities, habitats, species and their life cycles??

The average acidity (pH) of the world’s oceans has been stable for the last 25 million years. However, the oceans are now absorbing so much man made CO2 from the atmosphere that measurable changes in seawater pH and carbonate chemistry can be seen. It is predicted that this could affect the basic biological functions of many marine organisms. This in turn could have implications for the survival of populations and communities, as well as the maintenance of biodiversity and ecosystem function.

Special Issue – Seawater Acidification – will be published in Water

The following Special Issue will be published in Water (, ISSN 2073-4441), and is now open to receive submissions of full research papers and comprehensive review articles for peer-review and possible publication:

Special Issue: Seawater Acidification
Guest Editors: Dr. Sam Dupont and Prof. Dr. Mike Thorndyke
Deadline for manuscript submissions: 31 May 2011

You may send your manuscript now or up until the deadline. Submitted papers should not have been published previously, nor be under consideration for publication elsewhere.
