EPOCA: Ocean Acidification and its Consequences on Ecosystems

26.05.2008
Emissions of carbon dioxide (CO2) through human activities have a well-known impact on the Earth's climate. Its other, less well-known, impact is "ocean acidification", with uncertain consequences on marine organisms and ecosystems.

The European Project on Ocean Acidification (EPOCA) will be launched on 10 June 2008. Its goal is to document ocean acidification, investigate its impact on biological processes, predict its consequences over the next 100 years, and advise policy-makers on potential thresholds or tipping points that should not be exceeded.

The World's oceans cover over 70% of the planet's surface, contribute half of its primary production and contain an enormous diversity of life. Thus it is not surprising that they provide invaluable resources to human society. They also play a vital role in Earth's life support system due to their impact on climate and global biogeochemical cycles and due to their capacity to absorb atmospheric carbon dioxide (CO2).

The oceans currently absorb half of the CO2 produced by burning fossil fuels. Put simply, climate change would be far worse if it was not for the oceans. However, there is a cost to the oceans. When carbon dioxide dissolves in seawater, it forms carbonic acid. As more CO2 is taken up by the oceans surface, the pH (a measure of acidity, the lower the pH the greater the acidity) decreases, moving towards a more acidic state. This change is called "ocean acidification" and is happening at a rate that has not been experienced for at least 400,000 years and probably for the last 20 million years.

The overall goal of the European Project on Ocean Acidification (EPOCA) is to fill the numerous gaps in our understanding of the effects and implications of ocean acidification.

- EPOCA aims to document the changes in ocean chemistry and biogeography across space and time. Paleo-reconstruction methods will be used on several biological archives, including foraminifera and deep-sea corals, to determine past variability in ocean chemistry and to tie these to present-day chemical and biological observations.

- EPOCA will determine the sensitivity of marine organisms, communities and ecosystems to ocean acidification. Molecular to biochemical, physiological and ecological approaches will be combined with laboratory and field-based perturbation experiments to quantify biological responses to ocean acidification, assess the potential for adaptation, and determine the consequences for biogeochemical cycling. Laboratory experiments will focus on key organisms selected on the basis of their ecological, biogeochemical or socio-economic importance. Field studies will be carried out in regions of the ocean deemed most sensitive to ocean acidification.

- Insights into the impacts of ocean acidification will be integrated in biogeochemical, sediment and coupled ocean-climate models to better understand and predict the responses of the Earth system to ocean acidification. Special attention will be paid to the potential feedbacks of the physiological changes in the carbon, nitrogen, sulfur and iron cycles.

- EPOCA will assess uncertainties, risks and thresholds ("tipping points") related to ocean acidification at scales ranging from sub-cellular to ecosystem and local to global. It will also assess pathways of CO2 emissions required to avoid these thresholds and describe the change and the subsequent risk to the marine environment and Earth system, should these emissions be exceeded.

Led by the Centre National de la Recherche Scientifique (CNRS), the EU Framework 7 Collaborative Project EPOCA is run by a consortium of 27 partners across 9 countries involving many of the leading oceanographic institutions across Europe and more than 100 permanent scientists. The budget of this 4 year project is 16.5 M€ with a contribution from the European Commission of 6.5 M€.

The Alfred Wegener Institute (AWI) conducts research in the Arctic, Antarctic and in oceans of temperate and high latitudes. The AWI coordinates polar research in Germany, and provides important infrastructure, such as the research icebreaker Polarstern and research stations in the Arctic and Antarctic for international science organisations. The Alfred Wegener Institute is one of 15 research centres of the 'Helmholtz-Gemeinschaft' (Helmholtz Association), the largest scientific organisation in Germany.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
