The Pioneering Voyage of the HMS Challenger | Natural World Facts [ Discovery ]

The HMS Challenger set out on its 3-year voyage in 1872. This expedition was to be the first of its kind. One organised specifically to gather data on the ocean environment and its inhabitants. During its 127,580 km (79,280 mi) journey circumnavigating the globe, the crew on board the Challenger took 492 deep sea soundings, and 284 dredges and trawls. This led to the discovery of 4,700 new species of marine life, recorded in volumes and illustrated by the official expedition artist, John James Wild.
