A humpback whale may be a huge creature to the human eye, but they're still tough to spot from space.
Until recently, the necessary high-resolution satellite technology wasn't readily available, but researchers in Western Australia are beginning to use satellite imagery to check on the size of local populations.
The aim of the project is to keep tabs on Western Australia's humpback whale numbers, explained Curt Jenner, managing director of the Centre for Whale Research.
