Rare separately issued chart of the coasts of the western half of Australia, Spice Islands and New Guinea, focusing on the prevailing currents and winds, as observed by Matthew Fontaine Maury, then serving as Lieutenant in the U.S. Navy.
Includes an extensive note and key information.
The map tracks the various voyages of the American and other ships which surveyed the region and took measurements as part of Maury's landmark project.
Maury's seminal work on the Ocean's currents and related atmospheric phenomen was commenced in 1847, with the publication of his map of the currents of the North Atlantic (Schwartz & Ehrenberg 278) and culminated with The Physical Geography of the Sea, published in 1855. While preparing the charts Maury sought the cooperation of mariners from many nations, getting them to report to him their regular observations of winds and currents, which he either added or corrected on his own charts.
This was the Age of the great Clipper Ships, and their masters prized Maury's charts by following their wind and current directions. Many days off their voyages were cut from North American ports to the Far East, as well as the Clippers racing to and from New York and San Francisco.
Maury was the chief Naval Officer in charge of charts from 1843 to 1861. His work describing seasonal winds and currents was conceived largely outside conventional academic circles. Maury was made an honorary member of the Boston Marine Society, where his portrait was hung, and later turned upside down when he later elected to join the Confederacy during the American Civil War.
