One hundred and fifty years ago, today…

The Challenger expedition of 1872–1876 was a scientific program that made many discoveries to lay the foundation of oceanography. The expedition was named after the naval vessel that undertook the trip, HMS Challenger.

The expedition, initiated by William Benjamin Carpenter, was placed under the scientific supervision of Sir Charles Wyville Thomson of the University of Edinburgh and Merchiston Castle School, assisted by five other scientists, including Sir John Murray, a secretary-artist and, a photographer. The Royal Society of London obtained the use of Challenger from the Royal Navy and, in 1872, modified the ship for scientific tasks, equipping it with separate laboratories for natural history & chemistry. The expedition, led by Captain Sir George Strong Nares, sailed from Portsmouth, England, on [December 21, 1872]. Other naval officers included Commander John Maclear.

Under the scientific supervision of Thomson himself, the ship traveled approximately 68,890 nautical miles (79,280 miles/127,580 kilometres) surveying and exploring. The result was the Report of the Scientific Results of the Exploring Voyage of H.M.S. Challenger during the years 1873–76 which, among many other discoveries, catalogued over 4,000 previously unknown species. John Murray, who supervised the publication, described the report as “the greatest advance in the knowledge of our planet since the celebrated discoveries of the fifteenth and sixteenth centuries.” Challenger sailed close to Antarctica but, not within sight of it. However, it was the first scientific expedition to take pictures of icebergs.
