University Professor To Lead Investigation On Rising Acidity In Oceans

17.08.2004


Professor John Raven of the School of Life Sciences at the University of Dundee has just been appointed chair of the Royal Society’s working group on ocean acidification. The task of the working group is to assess the available evidence on the extent of acidification in oceans and its impact on marine life.



The Royal Society, the UK’s academy of science is launching the working group and study because of concerns that the world’s oceans are becoming increasingly acidic, due to pollution from the greenhouse gas carbon dioxide.

Oceans ‘mop up’ carbon dioxide from the atmosphere and this, in turn, increases the acidity of the water. Rising levels of the gas from the unmanaged burning of fossil fuels such as oil and coal may be exacerbating this. Professor Raven will contribute his specialist skills on how photosynthetic organisms acquire carbon to the working group’s investigation.


Currently, the impact of this rising ocean acidity on marine life is largely unknown. However, there are fears that it could particularly affect corals and sea creatures with hard shells. This is because acidification seems to decrease the availability of calcium carbonate from the water - which these creatures use to produce their hard skeletons. Increased acidity may also directly affect the growth and reproduction rates of fish, as well as affecting the plankton populations which they rely on for food, and have potentially disastrous consequences for marine food webs.

Professor Raven, a Principal Investigator in the Division of Environmental and Applied Biology said: “Our oceans may be doubly besieged. The same pollution that we believe is heating the world’s oceans through global warming is also altering their chemical balance. This study will look at what impact increased acidity levels might have on marine life and re-emphasise the urgent need to respond to the spectre of climate change, an issue identified by the UK Government as a priority for its Presidency of G8 in 2005.”

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Im Focus: Cold molecules on collision course

Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.

How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...

Im Focus: Shrinking the proton again!

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
