Sea Shepherd won't chase Japan whalers this year

Anti-whaling group Sea Shepherd has announced it will not send ships to the Antarctic Ocean this year to intercept Japanese whaling operations.

The group issued a statement on its website on Monday explaining that Japan is now using "military surveillance" to watch Sea Shepherd ship movements in real time by satellite. The group said that if their ship location is known at any given moment, it can be easily avoided, so they can no longer match Japan's "military grade technology."
