Fin whale cruising by a fibre-optic cable off Svalbard (VIDEO)
Caption
Researchers from the Norwegian University of Science and Technology now have a real-time stream of data from a fibre-optic cable between Longyearbyen and Ny-Ålesund in Svalbard. This short video shows a fin whale that cruised by the cable. The yellow "image" appears and then disappears at the bottom of the video towards the middle is actually a record of the frequency of the whale's vocalization, at 20 Hz. This is a typical frequency for fin whale vocalizations, which is how the researchers can identify it.
