Satellite Tracks Whales?For Science or Hunting?
A Japanese satellite to monitor the migration of minke whales will be launched in October. It will collect data from coconut-sized electronic tags that have been attached to whales using airguns. Used in combination with global positioning system technology, the tags should provide information on migratory routes as well as data on how deep the whales swim and how often they surface, says Tomonao Hayashi of the Chiba Institute of Technology, who helped develop the satellite system.
Satellite monitoring technology is used by groups around the world for scientific research into whale migration patterns. But some people fear the Japanese satellite will use the information to provide detailed data for use by the country?s whaling fleet.
