Carbon and Life in Deep Seafloor Rocks

23.10.2015

International Atlantis Massif Expedition started

On October 26th, an international team of scientists will sail from Southampton, UK, on board the British Royal Research Vessel James Cook. During a 6-week expedition in the Atlantic Ocean the team will explore the Atlantis Massif, a prominent, nearly 4,000 metre high underwater mountain which is part of the world`s longest mountain chain.

Led by Co-Chief Scientists Gretchen Früh-Green, ETH Zurich, Switzerland, and Beth Orcutt, Bigelow Laboratory for Ocean Sciences, USA, the team will collect cores of rocks using seabed rock drills. The plan is to drill at 11 sites in water depths of 720 to 1,770 metres and to recover cores between 50 and 70 metres in length.

“Scientifically the sea bed is remarkable because the Atlantis Massif is made up of rocks from the Earth's mantle”, says marine geologist Gretchen Früh-Green, who explored this remarkable sub-seafloor region already during expeditions in 2003 and 2005.

“In the presence of seawater these rocks produce the greenhouse gas methane, hydrogen and heat, among other things.” Such rock reactions excite scientists because they represent possible sources to fuel life in the absence of sunlight and may be analogous to conditions found on other planets, or early in Earth's history.

“Among other things we hope to learn more about what kind of life exists on and within rocks at the Atlantis Massif”, says marine microbiologist Beth Orcutt. “Moreover we shall investigate the fate of carbon. Do the reactions between rocks and seawater lead to carbon storage in the seafloor? And does this process impact the global carbon cycle and our climate?”

Overall the expedition aims to study
• how mantle rocks are brought up to the seafloor,
• how the rocks react with seawater,
• how carbon is cycled during this process,
• what type of life exists on and within the rocks and how organisms can survive in this extreme environment.

The expedition is conducted by the European Consortium for Ocean Research Drilling (ECORD) as part of the International Ocean Discovery Program (IODP). Two rock drills were installed on the RRS James Cook, operated by the British Geological Survey and MARUM, the Center for Marine Environmental Sciences in Bremen/Germany. It is the first expedition of this kind to use this type of remotely operated drilling technology.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
