"As soon as humans spied and later set foot on the remote Antarctic continent in the early nineteenth century, they became aware of its ice cover, and desired to learn about its extent, shape, thickness, and behavior. In this book, David Drewry-glaciologist and former Director of the Scott Polar Research Institute-recounts the science and history of a ground-breaking time in recent Antarctic geophysical exploration, in which scientists were finally able to "see" through the Antarctic ice sheet and take its measure. From the mid-1960s to the mid-1980s, scientists' ability to peer beneath the Antarctic ice sheet and map its thickness was revolutionized by the technology, techniques, and exploratory campaigns of the Radio Echo Sounding Programme, conducted by the Scott Polar Research Institute at Cambridge in the UK. The exploratory radar mapping campaigns of this ambitious research program were largely accomplished during the Cold War, as interest and concern in global climate change were just emerging. To those involved in this research and fieldwork, it was evident that the environment of the planet was indeed changing, and that the great ice masses of Antarctica and Greenland, and their evolving stability and behavior, would feature significantly in understanding the future of our world. This book gives an account of the Radio Echo Sounding Programme, describing the scientific background, goals, various scientific, human, political, and natural challenges, and discoveries of the research program. It follows the twists and turns of operating in a remote and hostile region, where detailed and exact planning and preparations were constantly at risk of disruption by bad weather, mechanical and electronic breakdowns, aircraft crashes, and human frailty. It also highlights the strong international cooperation that occurred in Antarctica, during this contentious time in history, speaking to the importance of the 1961 Antarctic Treaty as well as the necessity of working together to tackle problems of global significance"--
Antarctica, the sixth continent, was discovered more than 160 years ago. Since then this large, mysterious continent of ice and penguins has attracted world interest. Scientific expeditions from various countries have begun to study the geographical and natural conditions of the icy continent. Systematic and comprehensive inves tigations in the Antarctic started in the middle of our century. In 1956 the First Soviet Antarctic Expedition headed to the coast of Antarctica. Their program included studies of the atmosphere, hydrosphere and cryosphere. Thirty years have since passed. Scientists have unveiled many secrets of Antarctica: significant geophysical processes have been investigated, and a large body of new information on the Antarctic weather, Southern Ocean hydrology and Antarctic glaciers has been obtained. We can now claim that the horizons of polar geo physics, oceanology, and particularly glaciology, have expanded. Scientific inves tigators have obtained new information about all Antarctic regions and thus have created the opportunity to use the Antarctic in the interests of mankind.
Highlighting twenty years of U.S. scientific research conducted since the International Geophysical Year (IGY) of 1957-58, this volume marks a turning point in the history of polar investigations and provides a lucid summary of the contributions of many distinguished scientists. The authors provide an overview of major polar research programs, past and present; explore concepts derived, from highly interrelated aspects of physical and life sciences; and seek to offer a glimpse of future polar science and polar development. The introduction briefly describes major physical, biological, and interdisciplinary research programs, as well as the magnitude, extent, and international character of contemporary polar science. Twenty years of polar biological investigations are then reviewed, and subsequent chapters address principles and advances in meteorology, physical oceanography, glaciology, and the geological evidence that hears on the origin of Antarctica. These physical sciences delineate a matrix for the polar biospheres and provide a background for understanding the major categories of structure and dynamic functioning of the marine ecosystem, polar marine mammals, adaptational physiology, and terrestrial biotic adaptations.
The fourth international symposium on Antarctic Earth Sciences took place in Adelaide, South Australia during the week 16-20 August 1982. This volume contains a record of the centenary activities celebrating Sir Douglas Mawson and the one hundred and seventy-four papers that were presented by delegates for discussion over the five days. Sir Douglas Mawson was part of the first team to reach the magnetic South Pole, a leading geologist and scientific figure during the heroic age of of antarctic exploration. The papers presented during the symposium were divided into fifteen categories covering east and west Antarctica, marine, land and glacial geology, plate tectonics, islands, peninsulas, climatic change and Precambrian and Cenozoic era activity. The two hundred persons from sixteen countries who attended the symposium brought together a wide range of the most current expertise and research to share, of which this volume provides a record.
This beautifully illustrated book reviews the development of science in Antarctica from its early beginnings, in the age of Captain Cook, to the present complexity of the 1980s when research teams from many nations work side by side. Three major areas, biological science, the earth sciences and atmospheric science are examined individually, highlighting the principal achievements of the past 25 years, and providing an up-to-date account of our present understanding of this frozen continent. Concern over the future of the Antarctic Treaty and the probable main directions of future research, provide an indication of the importance of Antarctica to all scientific disciplines. This unique natural laboratory for science is now being investigated by eighteen countries. International interest in Antarctica grows apace and, whatever its future use by mankind, its sensible management will require a good, scientific basis.
