Crowdsourcing Moby Dick! Modern and historical data identify sperm whale habitat offshore of SW Australia
The distribution and use of the pelagic habitat by sperm whales (Physeter macrocephalus) is generally poorly understood in Western Australia. However, a variety of data are becoming available to researchers via online portals from where records of historical expeditions, commercial whaling operation...

However, a variety of data are becoming available to researchers via online portals from where records of historical expeditions, commercial whaling operations, and modern scientific research voyages can be accessed.

Four data sources were examined, the primary one being the Voyage of the Odyssey expedition, a five-year global study of sperm whales and ocean pollution. From December 2001-May 2002, researchers surveyed 5200 nautical miles off Western Australia including historical whaling grounds off Albany and the Perth Canyon, an area previously known for pygmy blue whale distribution, using acoustic techniques to obtain 57 tissue biopsies.
