ESA’s Envisat monitors oil spill

28.04.2010
These ESA Envisat images capture the oil that is spilling into the Gulf of Mexico after a drilling rig exploded and sank off the coasts of Louisiana and Mississippi, USA, on 22 April.

In the black-and-white radar image the oil spill is visible as a dark grey whirl in the bottom right, while in the optical image it is seen as a white whirl. The Mississippi Delta is at top left, and the Delta National Wildlife Refuge extends out into the Gulf.

Officials report that about 1000 barrels of oil a day is escaping from a damaged oil well located 1.5 km under the drilling rig. By yesterday afternoon, the spill was covering an area some 77 km long and 63 km wide.

The US Coast Guard, the National Oceanic and Atmospheric Administration, the London-based BP and oil industry experts are attempting to stem the leak and prevent it reaching the Gulf Coast and the fragile ecosystem there.

In order to observe the clean-up efforts, the US Geological Survey, on behalf of the US Coast Guard, requested satellite maps of the area from the International Charter Space and Major Disasters. The Charter is an international collaboration, initiated by ESA and the French space agency, CNES, to put satellite remote sensing at the service of civil protection agencies and others in response to natural and man-made disasters.

Envisat acquired these images from its Advanced Synthetic Aperture Radar (black and white) and Medium Resolution Imaging Spectrometer on 26 April at 15:58 UTC and on 25 April at 16:28 UTC, respectively.

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...
