Lithoprobe

right '''Lithoprobe''' was a Canadian national geoscience research project funded by the Natural Sciences and Engineering Research Council from 1984 to 2005, and one of the largest geoscientific research programs in Canadian history. The project aimed to research and map the lithosphere structure and composition, and its findings were used by scientists as well as petroleum and mining companies. By the end of the project, Lithoprobe had employed more than 1,000 scientists.<ref name="canencyclopedia">{{cite web |title=Geological Survey of Canada |url=https://www.thecanadianencyclopedia.ca/en/article/geological-survey-of-canada |website=The Canadian Encyclopedia |access-date=20 September 2022}}</ref>

The name "Lithoprobe" is derived from "probing the lithosphere". The project used 20-tonne trucks, called vibroseis trucks and nicknamed "dancing elephants," that forced seismic waves beneath the Earth to generate geological and historical data, allowing researchers to glean information from at least 80 kilometers beneath the Earth's surface.<ref name="cbc">{{cite news |title='Dancing elephants' help chart prehistoric Canada |url=https://www.cbc.ca/news/science/dancing-elephants-help-chart-prehistoric-canada-1.485083 |access-date=20 September 2022 |agency=CBC News |date=6 October 2004}}</ref>

==History== The concept of Lithoprobe was proposed at a 1981 meeting sponsored by Canada's Natural Sciences and Engineering Research Council, and the project itself launched in 1984. It was jointly funded by the Natural Sciences and Engineering Research Council and the Geological Survey of Canada.<ref name="deacon">{{cite news |last1=Deacon |first1=James |title=Birth of a continent |url=https://archive.macleans.ca/article/1992/12/7/birth-of-a-continent |access-date=20 September 2022 |agency=Macleans |date=7 December 1992}}</ref>
