The Great Whale Trail is a collaborative project between Greenpeace and scientists working on humpback whales in the South Pacific. The whales have been tagged in order to produce important information on the movements and migratory destinations of humpback whales from small, un-recovered populations off the Rarotonga (Cook Islands) and New Caledonia. Greenpeace is communicating this critical non-lethal scientific research to the wider public as part of their campaign against Japan's unnecessary lethal "research" in the Southern Ocean Whale Sanctuary.
