Margaret Woodward is a an artist and an an associate professor of design at Charles Sturt University. Artist statement: "The Sea is All Around us is a multi-layered event which creates a memorable experience for those visiting the Dome Gallery and the Mission to Seafarers in Melbourne’s Docklands. The event acknowledges and raises awareness of the often difficult and dangerous working lives and journeys of seafarers by making visible their role in transporting commodities, materials and objects to and from Australia’s shores. This installation at the Dome Gallery in the Mission to Seafarers in Melbourne’s Docklands marks the third stage of an ongoing research project which seeks to reveal the ‘social life’ of souvenirs. Beyond their representational role souvenirs also trigger intangible, affective qualities – reminders of journeys and places, new associations with tastes, sounds and people, and thereby becoming objects which focus and hold memories. This installation invites seafarers and visitors to participate in a global project which aims to witness sea journeys and trace the mobile life of seafarers and souvenirs. For a fortnight in May 2015, the Dome Gallery became an architectural large scale compass, with the circular floor marking the intersection of its latitude and longitude (37 º 49'21" S 144º 57'03"E). Over these two weeks the Dome Gallery was inscribed with marks recording journeys made by seafarers, recording destination and departure ports, home lands and waterways, and in doing so making visible a small segment of the global patterns of seafaring. Custom-made souvenirs designed for the installation are given to seafarers as gestures of welcome and a memento of their visit. The souvenirs originating in Poland continue their journey by sea, to destinations beyond the Dome becoming part of the global network of seafaring, with an invitation for seafarers to record their future journeys using QR code scanning technologies. It is hoped that by releasing the 200 limited edition souvenirs accompanying the seafarers the mobile life of souvenirs and seafarers will also become visible. Like messages in bottles they leave our shores, becoming ambassadors, representing the Dome Gallery at the Mission to Seafarers, the waters of Port Phillip Bay, Australia’s red soil and vegetation, and carrying memories of visiting Melbourne." The Mission has always been open to the community and has a tradition of hosting cultural events: shows, concerts, exhibitions, festivals.Orange enamel and teal mug created for the art installation by artist Margaret Woodward at the Mission to Seafarers.

An aeronautical chart is a map designed to assist in navigation of aircraft. Using these charts and other tools, pilots are able to determine their position, safe altitude, best route to a destination, navigation aids along the way, alternative landing areas in case of an in-flight emergency, and other useful information such as radio frequencies and airspace boundaries. World aeronautical charts have a scale of 1:1,000,000 and cover relatively large areas. Orbost Aero Club began in 1969 with Basil Dowie as Chair, David Nixon as Secretary/Treasurer. The group went into recess from 1977-1991 closing in 1997. The mid 1960s were boom years in flying training in Australia and the number of Aero Clubs grew rapidly. The Club played a significant role in the establishment of the small airport at Marlo and in the ongoing operation and development of the airport over the years particularly for patient transfer by aerial ambulance.

Charles George Eastland Platts arrived in South Australia on 22 March 1839, and soon after established his business in Adelaide. He became Adelaide’s first bookseller. It was known as Platts’ Library but was also a bookshop and stationer. His business was also used as a postal receiving house. Platts died on 14 November 1871. Boyle Travers Finniss (18 August 1807 – 24 December 1893) had an early career in the British Military before selling off his commission in 1835. He was appointed assistant surveyor to Colonel William Light in South Australia. He then had several roles in public service. Finniss was the first premier and Chief Secretary South Australia, serving from 24 October 1856 to 20 August 1857. In 1864 he was appointed as the Government Resident of the Northern Territory. He was filling this role at the time when the map was produced and is acknowledged on the map.This is a very early map documenting the exploration and opening up of Australia.Map of Australia and part of Indonesia.

This technical textbook is the nineteenth edition of the book by Henry Raper, Lieutenant in the Royal Navy with awards that include F.R.A.S. (Fellow of the Royal Astronomical Society) and F.R.G.S. (Friend of the Royal Geographical Society). The book is dedicated in honour of Rear-Admiral Sir Francis Beaufort K.C.B., Hydrographer to the Admiralty. He was awarded the title K.C.B. (King's Commander) as a Member of the Order of Bath, an order of British Chivalry, The book was first published in 1840 and soon became a resource for navigation students. It includes topics on nautical navigation, astronomy, navigation charts, calculations and mathematical tables, time, tides, ships, longitude, and position at sea. Thomas A. Hull, who revised and expanded this edition, was a Commander in the Royal Navy and had previously been Superintendent of Admiralty Charts used for navigation worldwide by seamen from many walks of life. The publisher, J D Potter of London, was at that time the sole agent for the Admiralty Charts produced by the Royal Navy. Printer Spottswoode and Co.,. was established by William Strachan in 1738. In 1819 his nephews A and R Spottswoode took over the business and bought premises in New-Street Square and Shoe Lane. In 1850 over 200 workers were employed by the firm. and five years later the business became Spottswoode & Co. Andrew Spottswoode invented the Spottswoode Press.This technical book was very popular as a textbook for students of maritime navigation, written and updated by members of the British Royal Navy and relied upon for accurate advice and information. The first edition was published in 1840, this edition was updated, expanded and published in 1891 when ports around the world were filling with travellers, merchants and business people.

A sextant is an astronomical instrument used to determine latitude and longitude at sea by measuring angular distances, especially the altitudes of the sun, moon, and stars. It is a doubly reflecting navigation instrument and used mainly by sailors to measure the angular distance between two visible objects. The name comes from the Latin sextans, or “sixth part of a unit,” because the sextant’s arc can be 60° or 120° of a circle depending on the model used. The primary use was to measure the angle between an astronomical object and the horizon for the purposes of celestial navigation. The estimation of this angle is known as sighting or shooting the object, or taking a sight. This angle and the time when it was measured is used in order to determine Greenwich Mean Time and hence longitude. Sighting the height of a landmark on land can also give a measure of distance from that object. History: The development of the sextant was as an improvement over the octant, an instrument designed to measure one's latitude. The octant was first implemented around 1731-present but can only measure angles up to 45°. As larger angles were needed to allow the measurement of lunar objects - moon, stars and the sun - at higher angles, the octant was superseded by the sextant. The sextant is a similar instrument but better made and allows larger angles from 60° to 120°. This improvement allows distances to be accurately calculated thereby giving longitude when used with a chronometer. The sextant was derived from the octant in 1757, eventually making all previous instruments used for navigational positioning obsolete. The sextant had been attributed to by John Hadley (1682–1744) and Thomas Godfrey (1704–1749), but reference to the sextant was also found later in the unpublished writings of Isaac Newton (1643–1727). Earlier links can be found to Bartholomew Gosnold (1571–1607) indicating that the use of a sextant for nautical navigation predates Hadley's implementation. In 1922, the sextant was modified for aeronautical navigation by Portuguese navigator and naval officer Gago Coutinho. It should be noted that the octant and quadrant are in the same family as they were, and all are, regarded as sextants. The sextant is representative of it's type and although not fully complete it demonstrates how 18th,19th and 20th century mariners determined their latitude and longitudinal to determine their position on a chart, allowing them to navigate there way across the world's oceans. It also demonstrates the skill and workmanship of the early instrument makers that operated scientific instrument businesses from London and other areas of England to provide most of the navigational instrumentation used by commercial and military navies of the time.Sextant with square, fitted box of polished wood, "Hezzanith" brand.

This is a set of 10 photographs of surveyors and support staff in the field undertaking duties in the Northern Territory and North Queensland in 1959 – 1960. The surveyors were employed in the establishment of mapping and geodetic control. In this era surveyors used theodolites to observe horizontal and vertical angles and tellurometers to measure base line distances between survey stations. Laplace survey observations seen in Photo .1P was a series of precise observations carried out at geodetic survey stations to determine astronomic latitudes, longitudes and azimuths to achieve maximum precision in the survey network. Laplace observations were necessary in a geodetic network at every 6th survey station, however the National Mapping Council specified at this time the spacing would be ideally between 4-6 survey stations. The cairn shown in photo .4P was built by RASvy as a landmark over a trigonometric survey station. It was dismantled in 1960 to enable re-occupation and survey observations. It was not restored to the condition shown in the photo.This is a set of 10 photographs of surveyors and support staff in the field undertaking duties in the Northern Territory (NT) and Queensland (QLD) in 1959 – 1960.

This representative example demonstrates a mariner’s astrolabe. Historical examples are rare. There are less than one hundred known to exist and most of these have been recovered from shipwrecks, many from Spanish and Portuguese vessels. An astrolabe is a measuring device once used to navigate the seas by observing the sun and stars to measure their altitude. The measurement of altitude could then be used to calculate the ship’s latitude but at that time in history there was no means of measuring longitude. The body of the navigational astrolabe was cast brass and much heavier, and less complicated than the variety used on land. The heavier weight and cut-away shape reduced the effect of the wind and waves when trying to use it at sea. A mariner’s astrolabe or ‘star finder’ is a simplified version than that used by Arabic astronomers to find the altitude of the sun and stars above the horizon, and time of the sunrise and sunset. It is a forerunner to the quadrant, octant and sextant and was popular for about 200 years over the 1500s and 1600s to find the latitude of a ship at sea. The user held the astrolabe at eye level and, usually with assistance, aligned the stars through the two small sights (pinnules), then read the altitude indicated by the pointer on the arm. It could also be used to sight the sun by holding it lower down, aiming it at the sun, and adjusting it until the sun shone through both pinnules. This astrolabe is an example used to demonstrate the mariner’s astrolabe, which was navigational tool of the 1500s and 1600s, in the time before longitude was able to be determined. It is a forerunner to modern navigation technology. Mariner’s astrolabe – a representative example. A gold painted, disc shaped object with cut outs and revolving arm in centre.

An Octant is a doubly reflecting navigation instrument used primarily by sailors to measure the angular distance between two visible objects and was a forerunner of the sextant. The name comes from the Latin octo, or “one-eighth of a circle,” for the Octant’s arc which spans 45°, or one-eighth of a circle. The primary use of an Octant is to measure the angle between an astronomical object and the horizon for the purposes of celestial navigation. The estimation of this angle is known as sighting or shooting the object, or taking a sight. The angle, and the time when it was measured, can be used to calculate a position line on a nautical chart (latitude), for example, sighting the Sun at noon or Polaris at night (in the Northern Hemisphere) gives an angle by which the latitude can then be estimated. Sighting the height of a landmark on land can also give a measure of distance. History: The principle of the Octant as an instrument to measure ones latitude was first implemented around 1742-present but was superseded by the improvement of the octant to a sextant, a very similar instrument, better made and able to measure bigger angles 120°, allowing the measurement of Luna distances to give longitude when used with an accurate chronometer. The sextant started to appear around 1730 and had been attributed to by John Hadley (1682–1744) and Thomas Godfrey (1704–1749), but reference to the sextant was also found later in the unpublished writings of Isaac Newton (1643–1727). Earlier links can be found to Bartholomew Gosnold (1571–1607) indicating that the use of a Sextant for nautical navigation predates Hadley's implementation. In 1922, the sextant was modified for aeronautical navigation by Portuguese navigator and naval officer Gago Coutinho. Henry Hemsley was a lesser-known instrument maker and optician working in London in the late 17th and early 18th century. However, it should be noted that there were two Henry Hemsley opticians and instrument makers around this period. (Henry Hemsley 1, 1786-89, who had premises at 85 Fleet St London and Henry Hemsley 2, 1828-56), whose workshop was at 135-138 Radcliff Highway London. Therefore, based on the inscribed workshop address Henry Hemsley 2 is responsible for making this example.The octant is representative of its type and although not fully complete it demonstrates how 18th and 19th-century mariners determined their latitude on a chart to navigate their way across the world's oceans in the 18th and 19th century. It also demonstrates the skill and workmanship of the early instrument makers that operated from London at this time and provided most of the navigational instrumentation use by commercial and military navies of the time.Octant, ebony wooden frame and handle.
