Sea Birds May Soon Need Rehabilitation
Oil spills are a real disaster. They cause worst troubles to sea birds and animals. A risk of an accident always exists within areas of oil mining and transporting, especially, in the sea. Beginning the exploitation of oil and gas fields on the sea shelf, our country is to face inevitable ecological problems, and it would be helpful to know in advance how to solve them.
An international conference on the impact of oil industry on wild animals was held in Hamburg in October of 2003. There, representatives from 17 countries of the world met up. They had many subjects to discuss, since the Old and New World coasts witnessed hundreds of oil accidents, among which the oil leaks from tankers Exxon Valdez, Erika, and Prestige were most disastrous. Our western neighbours have learned from that sad experience not only to cleanup the spill and assess damages, but also to rescue our lesser brothers. Oil traps are especially dangerous for birds. The nearest future of Russian economy is unimaginable without utilizing more fuel resources, and most of them are mined within the sea shelf. This makes us wonder, how we should act in case of a similar problems.
The question, whether such problems exist in the north of Russia now, has been addressed to Natalia Nikolaeva, WWF Russia marine program participant, who represented our country at the aforementioned conference. She gave the following comment. By the present time, there have been no places in the Russian sector of Arctic, where birds needed to be rescued from such a danger. But it is apparent that such problems will arise. Undoubtedly, oil will be mined within the northern shelf soon. However, our country has neither a service for bird rescuing, nor methods of work. Primarily, foreign handbooks on cleaning birds from oil slick should be translated into Russian. Then, specialists in bird rehabilitation should be coined. Ultimately, it is necessary to organize a centre that would promptly send emergency assistants anywhere.
The first step in saving dirty birds is to catch them and bring to a cleaning station. There, all parts of bird body are cleaned using sponges, toothbrushes, and special detergents and carefully rinsed with water. Oil-poisoned contents of the digestive tract are evacuated using a catheter. Cleaned birds are placed by groups numbering 10-15 individuals into small water pools, where they live during rehabilitation period under control of veterinarians. A complete rehabilitation course can last for up to a year, until birds moult and acquire a new plumage. Despite the care, the percentage of healed birds varies from 10% to 70% depending on the scale of pollution. It is obvious that the labour is very hard and demanding from a rescuer, who has to be highly professional and passionate about work.
Weather conditions in northern seas are very severe. Most of the winter time, there is darkness, storms, and ice. On the one hand, that increases the risk of accident, and, on the other hand, that makes it difficult to perform a rescuing operation. It is practically impossible to catch a bird, when waves are 2 m high (a mean wave height most typical in the Barents Sea). Hence, principally new approaches to bird rescuing are to be developed in Russia. Oil companies themselves should be concerned in supporting this research, because all around the world a company reputation depends on its ecological compliance.

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...
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...
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...
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...
