The scientists locate bears from a helicopter, tranquilize them, give them tattoo ID numbers and tags, and collect data such as height, weight, and body fat measurements and samples such as blood, hair, feces, and even teeth. For more than fortyyears, scientists have been capturing bears in order to get information. What has this information been telling scientistsabout polar bears and our changing global climate?
