  • HYDROGRAPHIC DEPARTMENT Charts, 1769-1824 Reel M406
    AUSTRALIAN JOINT COPYING PROJECT HYDROGRAPHIC DEPARTMENT Charts, 1769-1824 Reel M406 Hydrographic Department Ministry of Defence Taunton, Somerset TA1 2DN National Library of Australia State Library of New South Wales Copied: 1987 1 HISTORICAL NOTE The Hydrographical Office of the Admiralty was created by an Order-in-Council of 12 August 1795 which stated that it would be responsible for ‘the care of such charts, as are now in the office, or may hereafter be deposited’ and for ‘collecting and compiling all information requisite for improving Navigation, for the guidance of the commanders of His Majesty’s ships’. Alexander Dalrymple, who had been Hydrographer to the East India Company since 1799, was appointed the first Hydrographer. In 1797 the Hydrographer’s staff comprised an assistant, a draughtsman, three engravers and a printer. It remained a small office for much of the nineteenth century. Nevertheless, under Captain Thomas Hurd, who succeeded Dalrymple as Hydrographer in 1808, a regular series of marine charts were produced and in 1814 the first surveying vessels were commissioned. The first Catalogue of Admiralty Charts appeared in 1825. In 1817 the Australian-born navigator Phillip Parker King was supplied with instruments by the Hydrographic Department which he used on his surveying voyages on the Mermaid and the Bathurst. Archives of the Hydrographic Department The Australian Joint Copying Project microfilmed a considerable quantity of the written records of the Hydrographic Department. They include letters, reports, sailing directions, remark books, extracts from logs, minute books and survey data books, mostly dating from 1779 to 1918. They can be found on reels M2318-37 and M2436-67.

  • Extraordinary Sequence of Severe Weather Events in the Late-Nineteenth Century
    CSIRO PUBLISHING Journal of Southern Hemisphere Earth Systems Science, 2020, 70, 252–279 Review https://doi.org/10.1071/ES19041 Extraordinary sequence of severe weather events in the late-nineteenth century Jeff Callaghan Retired. Bureau of Meteorology, Brisbane, Qld., Australia. Postal address: 3/34 Macalister Road, Tweed Heads, NSW 2486, Australia. Email: [email protected] Abstract. Between 1883 and 1898, 24 intense tropical cyclones and extra tropical cyclones directly impacted on the southern Queensland and northern New South Wales coasts, with at least 200 fatalities in what was then a sparsely populated area. These events also caused record floods and rainfall, for example Brisbane City experienced its two largest ever floods over this period and Brisbane City set a 24-h rainfall record that still stands today. Additionally, a 24-h rainfall total of 907 mm occurred in a tributary of the upper Brisbane River resulting in a 15-m wall of water advancing down the river. Recent studies have shown that this part of Australia incurs the largest weather-related insurance losses. A major focus in this study is the seas these storms generated, leading to the loss of many marine craft and changes these waves brought to coastal areas. As a famous example of coastal erosion near Brisbane, the continual impacts from large waves caused a channel to form through Stradbroke Island to the open ocean forming two separate islands. Details of how this channel formed are described in relation to the storms. A climatology study of 239 Australian east coast storms that caused severe ocean damage between Brisbane and the Victorian border over the period between 1876 and February 2020 showed that 153 events occurred with a positive Southern Oscillation Index (SOI) trend and 86 events with a negative trend.

  • Severe Storms on the East Coast of Australia 1770–2008
    SEVERE STORMS ON THE EAST COAST OF AUSTRALIA 1770 – 2008 Jeff Callaghan Research Fellow, Griffith Centre for Coastal Management, Griffith University, Gold Coast, Qld Formerly Head Severe Storm Forecaster, Bureau of Meteorology, Brisbane Dr Peter Helman Senior Research Fellow, Griffith Centre for Coastal Management, Griffith University, Gold Coast, Qld Published by Griffith Centre for Coastal Management, Griffith University, Gold Coast, Queensland 10 November 2008 This publication is copyright. Apart from any fair dealing for the purpose of private study, research, criticism or review, as permitted under the Copyright Act, no part may be reproduced by any process without written permission from the publisher. ISBN: 978-1-921291-50-0 Foreword Severe storms can cause dramatic changes to the coast and devastation to our settlements. If we look back through history, to the first European observations by James Cook and Joseph Banks on Endeavour in 1770, we can improve our understanding of the nature of storms and indeed climate on the east coast. In times of climate change, it is essential that we understand natural climate variability that occurs in Australia. Looking back as far as we can is essential to understand how climate is likely to behave in the future. Studying coastal climate through this chronology is one element of the process. Analysis of the records has already given an indication that east coast climate fluctuates between phases of storminess and drought that can last for decades. Although records are fragmentary and not suitable for statistical analysis, patterns and climate theory can be derived. The dependence on shipping for transport and goods since European settlement ensures a good source of information on storms that gradually improves over time.

  • Geographic History of Queensland
    Q ueeno1anb. GEOGRAPHIC HISTORY of CLUEENSLAND. DEDICATED TO THE QUEENSLAND PEOPLE. BY ARCHIBALD MESTON. "IN all other offices of life ' I praise a lover of his friends, and of his native country, but in writing history I am obliged to d}vest myself of all other obligations, and sacrifice them all to truth ."- Polybiua. "Polybius weighed the authors from whom he was forced to borrow the history of the times preceding his own , and frequently corrected them , either by comparing them with each other, or by the light which be had received from ancient men of known integrity among the Romans, who had been conversant with those affairs which were then managed , and were yet living to instruct him. 'He who neglected none of the laws of history was so careful of truth that he made it his whole business to deliver nothing to posterity which might deceive them ."- Dryden 'a " Character of Polybiua." BRISBANE: BY AUTHORITY : EDMUND GREGORY GOVERNMENT PRINTER. 1895. This is a blank page AUTHOR'S PREFACE. Geography and history being two of the most important branches of human knowledge, and two of the most essential in the education of the present age„ it seems peculiarly desirable that a book devoted to both subjects should be made interesting, and appear something more than a monotonous list of names and cold bare facts, standing in dreary groups, or dismal isolation, like anthills on a treeless plain, destitute of colouring, life, and animation. In accordance with that belief, I have left the hard and somewhat dusty orthodox roadway, and out a " bridle track " in a new direction, gladly believing that the novelty and variety will in no way interfere with the instruction, which is the primary guiding principle of the work.

    Botanic Endeavour 250 Botanic Gardens Australia and New Zealand celebrates 250 years of the discovery by western science of the flora of New Zealand and Australia’s east coast in 1769-70 and over 40,000 years of traditional knowledge 2019 - 2020 1 Botanic Endeavour 250 Our plants our future In 2019 and 2020, botanic gardens and arboreta throughout Australia and New Zealand will commemorate the anniversary ‘voyage of discovery’ by Captain James Cook in the barque ‘Endeavour’ during which Joseph Banks and Daniel Solander made a comprehensive collection of flora. Cook mapped the entire coastline of New Zealand in 1769 before traversing the east coast of Australia in 1770 from Point Hicks to Cape York. Pressings of over 520 new taxa unknown to western science were collected along the route up the east coast of Australia and these, along with thousands of botanical illustrations, somehow made it back to England in the face of shipwreck, waterlogging and the dank and humid conditions below decks. The rich abundance of diverse flora excited the botanic world and ultimately led to the settlement of the new colony. 2019 in New Zealand and 2020 in Australia marks the 250th anniversary of these flora discoveries by western science. Our Australian indigenous heritage Prior to 1770, the original custodians of Australia lived in harmony with the land for over 40, 000 years and discovered the ethnobotanic use for Australia’s native flora for food, medicine, tools, clothing, and building materials. After the recording of such unusual and previously undocumented flora along the journey, Banks became a lifelong advocate for the settlement of the ‘new continent’ at Botany Bay.
