The Challenger Expedition of 1872–76 laid the foundations of the academic discipline of oceanography. The Royal Navy ship HMS Challenger was modified for scientific work, with laboratories for natural history and chemistry. The ship sailed from Portsmouth, England, on 21 December 1872 and travelled nearly 70,000 nautical miles over four years, surveying and exploring. The result was the 50 volume The Report of the Scientific Results of the Exploring Voyage of HMS Challenger during the years 1873-76 that took 20 years to complete and catalogued over 4,000 previously unknown species.
