  • Dr. Steve Amstrup, lead biologist for the USGS polar bear capture project, instructing a co-worker on the fine points of shooting a dart gun at a running polar bear from a moving helicopter. Kaktovik, Alaska
    D125196.jpg
  • Dr. Steven Amstrup, lead scientist for the US Geological Survey, darts a female polar bear on the Beaufort Sea. Darting the bears from a helicopter can be extremely treacherous. The pilot has to hover over a running animal that is twisting and turning, dodging and ducking, an animal that feels it's running for its life. This bear is hit directly between the shoulders with an immobilizing dart. It takes anywhere from 4-15 minutes for the drug to take effect and immobilize the bear which will be out for 1-2 hours as the scientists process the data.
