Marine deserts could give clues to understanding climate change

15.04.2004


Remote ‘marine deserts’ in the Atlantic Ocean could provide scientists with valuable clues to understanding climate change.

A research team led by the Plymouth Marine Laboratory will shortly set sail from the Falkland Islands, for the start of an expedition to study the interaction between tiny floating marine organisms (plankton) and the atmosphere. By monitoring the plankton and the influence of changing climate on its growth, they hope to discover whether the plankton act as a source of carbon dioxide, or a sink in which the carbon is contained.

The areas of marine desert, known as gyres, have been studied very little in the past. Because they are home to very small populations of plankton and fish that feed on it, the researchers expect very different results from this study compared to studies in more densely populated areas.



The expedition, aboard the RRS James Clark Ross, is part of the Atlantic Meridional Transect Programme (AMT), a £2.3 million project funded by the Natural Environment Research Council. The RRS James Clark Ross is taking time out of its annual trip back to the UK to assist the research team.

Says Dr Carol Robinson, head of the AMT programme, “We’re basically hitching a ride aboard the James Clark Ross and buying some research time to visit the gyres, which are well away from the normal shipping routes. I’m really excited about what we might find from this sparsely populated area, compared to our last cruise which studied areas teeming with plankton.”

Combined with results from earlier expeditions, this study will provide a unique 10 year data set which will aid scientists in their studies of long-term impacts of climate change.

The research voyage begins on Monday 26 April, with 21 British scientists aboard the Royal Research Ship James Clark Ross.
The RRS James Clark Ross is a British Antarctic Survey (BAS) vessel. The ship is currently heading back to Port Stanley in the Falklands on the final leg of its latest Antarctic cruise. BAS is a component of the Natural Environment Research Council (NERC).

The current AMT programme is a series of six research cruises that transect the Atlantic Ocean in April and September each year. 12 similar cruises have taken place since 1995. The programme involves scientists from six UK institutes, led by Plymouth Marine Laboratory. The others are: the Universities of East Anglia, Liverpool, Newcastle and Plymouth, and the Southampton Oceanography Centre. More information can be found at www.amt-uk.org

Plymouth Marine Laboratory (PML) is an independent and impartial collaborative centre of NERC. On the 1st April 2002 PML transferred from being a wholly owned NERC research centre to form an independent organisation with charitable status.

The Natural Environment Research Council is one of the UK’s seven Research Councils. It uses a budget of about £300 million a year to fund and carry out impartial scientific research in the sciences of the environment. NERC trains the next generation of independent environmental scientists. It is currently addressing some of the key questions facing mankind, such as global warming, renewable energy and sustainable economic development.

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...

Im Focus: How to inflate a hardened concrete shell with a weight of 80 t

At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).

Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...

Im Focus: Bacterial Pac Man molecule snaps at sugar

Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...

Im Focus: Repairing defects in fiber-reinforced plastics more efficiently

Fiber-reinforced plastics (FRP) are frequently used in the aeronautic and automobile industry. However, the repair of workpieces made of these composite materials is often less profitable than exchanging the part. In order to increase the lifetime of FRP parts and to make them more eco-efficient, the Laser Zentrum Hannover e.V. (LZH) and the Apodius GmbH want to combine a new measuring device for fiber layer orientation with an innovative laser-based repair process.

Defects in FRP pieces may be production or operation-related. Whether or not repair is cost-effective depends on the geometry of the defective area, the tools...
