Sir George's early career had been involved with physical oceanographic studies in the cold southern waters. Later he undertook research on ocean waves and was knighted for his contribution to oceanography. On the occasion of his visit to Sydney University, he not only showed us Hurley's hand-cranked movie of Mawson's Discovery under sail, but also drew our attention to Prestwich's 1875 compilation and appraisal of the deep sea thermometry of the predecessors of the Challenger expedition of 1872 to 1876. To this, Sir George's last visit to the Antipodes, we owe the inspiration for this account of the contribution to oceanography of investigations in the South Seas. We would like also to take this opportunity to thank both Cynthia Jones and Alexander Jones for their assistance and encouragement during this project. Bruce Hamon, formerly of the CSIRO in Sydney kindly read our manuscript and made many valuable suggestions. While the records of many of the labours of earlier oceanographers are difficult to retrieve, the holdings of the Mitchell Library in the Library of New South Wales and the Fisher Library of the University of Sydney have proved invaluable to us. Many long neglected reports and measurements are to be found in scattered papers and articles, but here we have attempted to draw together into one volume the story of the development of physical oceanography in the waters of the Pacific Ocean. 3 Oceanography in the days of sail PREFACE Man lives on a planet of which almost two thirds is covered by ocean. This ocean has been the main means by which products, faiths and ideas have spread from one continent to another. In maritime societies, the natural history of the seashores had long aroused the interest and curiosity of those who lived near the sea. The behaviour of the coastal waters upon which our ancestors sailed and fished had a very practical importance. Scientific interest in the sea dates back at least to Greek and Roman times. Tidal behaviour, in particular, being very visible, became an early subject of interest and observation in early China. As observation and experimentation increased in importance as a source of knowledge, and the study of 'natural history' advanced and then subdivided into separate sciences, the study of the sea advanced within each of these sciences. As European communities, in particular, sent their sailing vessels further and further afield, the curiosity of the scientifically inclined found an ever enlarging source of nourishment in the observations that were now possible of the wider oceans and distant seas. Supported by those with the practical goals of improving navigation and reducing the risk of foundering, the inquisitive were able to build a description of the oceans. With improved instrumentation, and the capacity to measure and record came the interest in the physical aspects of oceanic behaviour and the beginnings of the science of physical oceanography. The waters of the Pacific have played an important part in the development of the science of oceanography, not so much because of the contribution from littoral scientists but because Oceania was the focus of many European scientific expeditions in the enlightened eighteenth and nineteenth centuries. These expeditions, organised in the days of sail power, were conducted in the face of hardships and dangers unknown today. The narratives of their voyages were eagerly read in their day and still have the power to excite our interest and admiration. While we may be well acquainted with the stories of the most famous of these explorers, of Bougainville and Lapérouse for France and of James Cook for England, we are not so familiar with the efforts of the many others who surveyed the coastlines and probed the deeper ocean in the nineteenth century when European penetration of the southern hemisphere 4 Oceanography in the days of sail was reaching its peak. We here propose a review of the work of the most important contributors to our knowledge of the seas, a review in which we shall tell chiefly of their work in the physical sciences and in the South Seas. Considerable advances in scientific knowledge were achieved before the search for Terra Australis and the exploration of the Pacific became a subject of interest to Europeans and a focus for the study of marine science. For those who wish to know of the earlier developments in geographic knowledge and the knowledge of the tides, currents and waves, the article by Murray (1895) in the HMS Challenger reports provides a good starting point. The discoveries by civilisations other than European are not so readily available. This book will be of interest to those drawn by the romance of the sea: to sailors, yachtsmen, marine officers, hydrographers and marine scientists. They may wish to know of the adventures associated with exploring and measuring the southern seas in the days of sail, and of the qualities of persistence and leadership displayed by those in charge of the expeditions. The accomplishments of their predecessors will be of interest to contemporary environmentalists and oceanographers, as will the legacy they have left us. Measurements of the ocean were mostly made to satisfy curiosity. Only some few questions were of immediate practical consequence. Now, more than a century later, we are able to use the result of labours of the past to answer many economically important questions that would not have occurred to our ancestors. Can oil platforms withstand the waves and currents? How do fish stocks respond to surface currents? Or, more recently, what is the correlation between sustained droughts and the temperature of the tropical ocean surface? From a study of the measurements of the past comes the opportunity to assess questions such as the rate of climate change, since the deep ocean represents a large reservoir of heat that smooths the seasonal and inter-annual fluctuations in temperature. We should continue to build on the base of the curiosity-driven research of previous generations to ensure the sound management of the environment of our planet. University of Sydney Institute of Marine Science NSW, 2009 5 Oceanography in the days of sail 'Revolutions pass, political opinions can vary endlessly, but facts gained for science endure to honour the memory of those who have contributed to their acquisition. They are all landmarks set up by the generations which attest the gradual improvement of the spirit of man.' Dumont d'Urville (1833 ) Portrait of Dumont d'Urville 6 Oceanography in the days of sail Map of Pacific 7 Oceanography in the days of sail 1 In Search of Terra Australis Incognita Early Marine Knowledge Knowledge of the seas and oceans became of practical importance to mankind when trade, conquest and the imposition of religion became driving forces in the affairs of nations. Reliable travel by water depended upon knowledge not only of coastlines, reefs and shoals, but of tides, winds and currents. The possession of this information represented a strong commercial advantage. Competition for trade often precluded the passing of such information to others. Early mercantile civilisations in Europe, such as those in Crete and Phoenicia, relied upon trade for their prosperity by means of short-distance sailing routes within the enclosed Mediterranean Sea. As mercantile activity expanded out of the Mediterranean, knowledge of the tides, winds and currents of the oceans became more important. In the Persian Empire to the east, larger ships were built for use in the Indian Ocean and a grading system for sailors was introduced, based on their knowledge of the sea. In 55 BC the importance of information about the behaviour of the ocean was brought home to Julius Caesar during his first invasion of Britain.

  • The Death of Captain Cook in Theatre 224
    The Many Deaths of Captain Cook A Study in Metropolitan Mass Culture, 1780-1810 Ruth Scobie PhD University of York Department of English April 2013 i Ruth Scobie The Many Deaths of Captain Cook Abstract This thesis traces metropolitan representations, between 1780 and 1810, of the violent death of Captain James Cook at Kealakekua Bay in Hawaii. It takes an interdisciplinary approach to these representations, in order to show how the interlinked texts of a nascent commercial culture initiated the creation of a colonial character, identified by Epeli Hau’ofa as the looming “ghost of Captain Cook.” The introduction sets out the circumstances of Cook’s death and existing metropolitan reputation in 1779. It situates the figure of Cook within contemporary mechanisms of ‘celebrity,’ related to notions of mass metropolitan culture. It argues that previous accounts of Cook’s fame have tended to overemphasise the immediacy and unanimity with which the dead Cook was adopted as an imperialist hero; with the result that the role of the scene within colonialist histories can appear inevitable, even natural. In response, I show that a contested mythology around Cook’s death was gradually constructed over the three decades after the incident took place, and was the contingent product of a range of texts, places, events, and individuals. The first section examines responses to the news of Cook’s death in January 1780, focusing on the way that the story was mediated by, first, its status as ‘news,’ created by newspapers; and second, the effects on Londoners of the Gordon riots in June of the same year.

    CHAPTER 7 WUNSCH AND FERRARI 7.1 Chapter 7 100 Years of the Ocean General Circulation CARL WUNSCH Massachusetts Institute of Technology, and Harvard University, Cambridge, Massachusetts RAFFAELE FERRARI Massachusetts Institute of Technology, Cambridge, Massachusetts ABSTRACT The central change in understanding of the ocean circulation during the past 100 years has been its emergence as an intensely time-dependent, effectively turbulent and wave-dominated, flow. Early technol- ogies for making the difficult observations were adequate only to depict large-scale, quasi-steady flows. With the electronic revolution of the past 501 years, the emergence of geophysical fluid dynamics, the strongly inhomogeneous time-dependent nature of oceanic circulation physics finally emerged. Mesoscale (balanced), submesoscale oceanic eddies at 100-km horizontal scales and shorter, and internal waves are now known to be central to much of the behavior of the system. Ocean circulation is now recognized to involve both eddies and larger-scale flows with dominant elements and their interactions varying among the classical gyres, the boundary current regions, the Southern Ocean, and the tropics. 1.

Track B, Case study 4: Charles Darwin and a new understanding of life STEP 1 Case Study Introduction Here we will focus on some of the contributions and impacts of British naturalist Charles Darwin, whose ideas profoundly shaped not only science, but every sphere of life. Darwin’s descriptions of change over time and evolution showed that life developed through increasing complexity and diversity over millions of years. This raised questions about the basis of knowledge, belief, and understanding, and challenged the idea that faith alone could lead to enlightenment. It also showed the web of interrelated life, with humans a part of the animal kingdom rather than divinely appointed.

He called Groeten Inwick what is now Ice fjord (Hudson’s Great indraught in 1607) a name which was given to it by Poole in 1610. Barentz thought that Spitzbergen was part of Greenland. Barentz also discovered Prince Charles Foreland which he took to be an island and which was called Black point Isle by Poole in 1610. It was in 1612 that English Whalers named it after Prince Charles, son of James VI of Scotland, who became Charles I later. In 1607-1610, following the reports made by Hudson, of the Muscovy Company, a whaling industry was established in Spitzbergen.

  • Miles Down! Oceanography Through History
    MILES DOWN! OCEANOGRAPHY THROUGH HISTORY The history of oceanography is an international story of invention, individual adventure, and exploration that remains little-known. This exhibition presents an historical overview, using timelines, text, photographs, and profiles of oceanographic expeditions and individual scientists from around the world. Image: Colette Kerry From water’s edge, the oceans are as mysterious as the stars. In the 21st century, deep-sea exploration – like space exploration - is no longer a fantastic idea, but a fact of scientific life. How did we move below the surface to study the depths of the sea? This exhibition tells the story of curious humans posing questions about the oceans and developing the tools and technology to move miles down to explore the sea. The oceans that cover 71% of the world’s surface hide complex worlds within their depths. How ocean waters behave, what creatures inhabit the seas, what lies on the ocean floors, what makes up seawater: these are the questions that underlie the scientific study of the oceans - the science of oceanography. Oceanography is the scientific study of the oceans as complex, interrelated systems. It is a mixed science that combines many different approaches to understanding the watery portion of our planet. Physics explores the physical properties of the oceans, the currents and waves. It’s a study of matter and energy and the relation between them. Chemistry is concerned with the properties, composition, and structure of substances in the oceans and the changes they undergo when they combine or react. The geology of the seafloor explores the earth’s history, composition, structure and processes.

  • Cinnamomum Camphora) in Eastern Australia Brett J
    Chapter 14—Australia’s Ever-changing Forests VI: Proceedings of the Eighth National Conference on Australian Forest History. Brett J. Stubbs et al. (ed.). © 2012, ISBN 978-0-9757906-2-5 Saviour to Scourge: a history of the introduction and spread of the camphor tree (Cinnamomum camphora) in eastern Australia Brett J. Stubbs School of Environmental Science and Management, Southern Cross University, Lismore, NSW 2480 Introduction The 50th year commemorative book of Wyrallah Road Public School, in Lismore, New South Wales, records the lopping of camphor trees bordering the school grounds as a ‘milestone’ for 1999. In similar spirit, at Bexhill Public School near Lismore, on World Forestry Day, 26 March 2004, children were told about the need to remove camphor trees and replace them with native species. Palmwoods State School received a Queensland Arbor Day Award in 2005 for the removal from its grounds of an old camphor tree and the transformation of the stump into an artistic wood carving. It is highly incongruous that trees planted in school yards many years before to provide shade and shelter for children, and to beautify their environment, are now being destroyed, not because they are old and unsafe or have grown inconveniently big, but because of a prevailing attitude akin to revulsion which has developed towards the species. The foregoing are just a few examples of the present-day quest for the elimination of camphor trees from the landscape—a quest which is pursued with as much zeal and vigour in parts of eastern Australia as that to reinstate the region’s lost rainforest.
