The Al Shaheen oil field is located approximately 80 km north-east off the coast of Qatar in the Arabian Gulf. It is the largest offshore oil field in Qatar and it is operated by Maersk Oil on behalf of its partner Qatar Petroleum. The Al Shaheen area is a highly productive marine environment due to a combination of complex nutrient rich currents and high temperatures. The diverse marine ecosystem is exemplified by one of the world's largest aggregations of whale sharks (Rhincodon typus) that return to this area every summer. The whale shark is listed as vulnerable on the IUCN Red List of Threatened Species and is the largest fish in the world. Having to operate in an area that hosts such a unique natural event poses a challenge to the parties involved but after years of dedicated research the secret behind the annual aggregation of the whale sharks in the Al Shaheen field is now better understood. The knowledge that has been gleaned is currently being used to help prevent significant disturbance to these majestic species and at the same time, maintain an efficient operation. Seismic operations have been scheduled for periods outside of the known aggregation season, and vessel traffic has been restricted in certain areas of the field. These initiatives have revealed that cost effective environmental risk management is achieved by gaining the best possible understanding of the ecosystem that is being impacted. Unless substantial published information is available for the area of concern this will most often require dedicated and continued research efforts. The reward in taking an "Ecosystem Approach", however, is an opportunity to establish collaboration between the industry, regulators and academia, resulting in effective and well-documented mitigation measures.

The hull of the dredger "Yolo" here illustrated is 53 feet wide by 115 feet in length, with a depth of 11 feet. The boom is 145 feet in length and its greatest diameter is two feet. The capacity of the bucket, level full, is 4Yz cubic yards, but it has been known to lift

Bureau of Land Management Wilderness Study Areas The Federal Land Policy and Management Act (Public Law 94-579, October 21, 1976) requires the U.S. Geological Survey and the U.S. Bureau of Mines to conduct mineral surveys on certain areas to determine the mineral values, if any, that may be present. Results must be made available to the public and be submitted to the President and the Congress. This report presents the results of a mineral survey of part of the Alvord Desert (OR-002-074) and East Alvord (OR-002-073A) Wilderness Study Areas, Harney and Malheur Counties, Oregon.
