Greenpeace and scientists have been tracking humpback whales, with tagged tracking devices, while they migrate from their breeding areas in the South Pacific to their feeding grounds in the Southern Ocean.
Already, we have collected more useful data on whale migration patterns than 20 years of lethal research by the Japanese Fisheries Agency.
These tags, however, are not permanent and after two months the tags have stopped transmitting signals – although they could begin transmitting again at any time.
The data collected shows a lot of useful information such as stock structure, diet, migratory patterns, body length and whether a whale is pregnant. Without harpooning a single whale.
