The Bush administration is clamping down on scientists at the U.S. Geological Survey, the latest agency subjected to controls on research that might go against official policy. New rules require screening of all facts and interpretations by agency scientists who study everything from caribou mating to global warming. The rules apply to all scientific papers and other public documents, even minor reports or prepared talks. Some agency scientists, who until now have felt free from any political interference, worry that the objectivity of their work could be compromised. The new requirements state that the USGS's communications office must be alerted about information products containing high-visibility topics or topics of a policy-sensitive nature." The agency's director, Mark Myers, and its communications office also must be told -- prior to any submission for publication -- "of findings or data that may be especially newsworthy, have an impact on government policy, or contradict previous public understanding." In 2002, the USGS was forced to reverse course after warning that oil and gas drilling in Alaska's Arctic National Wildlife Refuge would harm the Porcupine caribou herd. One week later a new report followed, this time saying the caribou would not be affected.
