Scientists have demonstrated a new method for counting whales from space.
It uses very high-resolution satellite pictures and image-processing software to automatically detect the great mammals at or near the ocean surface.
A test count, reported in the journal Plos One, was conducted on southern right whales in the Golfo Nuevo on the coast of Argentina.
The automated system found about 90% of creatures pinpointed in a manual search of the imagery.
This is a huge improvement on previous attempts at space-borne assessment, and could now revolutionise the way whale populations are estimated.
