Description:
Scarce hydrographic chart extending from Port Phillip, Victoria to Green Cape, New South Wales, first issued in 1902, this map has additional corrections up to 1941. Coastal profiles at top.
The regular updating of Hydrographic charts by the Hydrographic Office was to ensure that commanders of ships, pilots and other mariners were able to have the most to up to date information available to safely navigate foreign waters and ports as new information of changes to sea depths, sand bars, wrecks or other any other pertinent nautical information that could hinder passage became available. As updated charts were offered for sale, the earlier outdated charts in the hands of mariners, pilots, ships owners and sailors were invariably discarded, subsequently making all British Admiralty issued hydrographic charts of the period rare.
Mapmaker:
Admiral Sir William James Lloyd Wharton (1843-1905)
Wharton was a British admiral and Hydrographer of the Navy. He joined the Royal Navy in August 1857 and was promoted to lieutenant in 1863. His first surveying work was in HMS Gannet, including work in the Bay of Fundy, where some of the highest tides in the world make surveying challenging. In 1870 he was part of an expedition in HMS Urgent to observe a total eclipse of the sun in Gibraltar. He was promoted to commander in 1872. As captain of Shearwater he carried out extensive surveying the Sea of Marmora and the Bosphorus, as well as in the Mediterranean and Indian Ocean. In the Bosphorus he designed ingenious methods to measure the flow at different levels, showing currents and counter-currents. In 1874, Wharton was involved in preparations for the observations of the transit of Venus, involving the transport of numerous chronometers to determine the longitude of observation stations in the Indian Ocean. He collaborated with David Gill on this work, who became a lifelong friend, and would later be Astronomer at the Cape of Good Hope. This work established an accurate longitude for the Sechelles, which Wharton would use as a basis for his African surveying work. From 1876, as captain of Fawn he surveyed the seas off East Africa. He was promoted to captain in 1880, and for the next two years worked on his manual Hydrographic Surveying. In 1882 he was appointed to H.M.S. Sylvia for survey work in South America, and observed the second transit of Venus in December 1882. On 1 August 1884 he was appointed to the post of Hydrographer of the Navy, which he held for the next twenty years. In 1895 he was promoted to rear-admiral.
