The navigator Matthew Fontaine Maury collected between 1842 and 1861 an extensive array of ship logs which enabled him to chart prevailing winds and sea currents, as well as their seasonal variations. While mariners were well aware of specific regional conditions such as the gulf stream, Maury was the first to comprehensively tally oceanographic conditions at the global level. Many of this information appeared in “The Physical Geography of the Sea”, published in 1855, which considered being the first significant oceanography textbook. Such knowledge enabled to considerably shorten the sailing time, especially over long-distance travel. For instance, a journey from New York to Rio de Janeiro was reduced by 32 days, without any technical improvements on the ship, but by simply taking better advantage of prevailing winds and sea currents. Maury was also able to demonstrate that using the longer eastbound sailing route rounding Cape Horn to sail from Australia to Europe or North America was actually faster than the shorter westbound sailing route rounding the Cape of Good Hope. The outcome was the creation of relatively well-defined navigation routes that followed dominant wind patterns. It represented a close to optimal use of routing for sailing which would remain until replaced by steamships in the late 19th century.
