Field guide for field trip following the XII INQUA Congress, 1987. Consists of four parts: part one presents an overview of the area of Cumberland Sound and Frobisher Bay in terms of present day climate, glaciology, bedrock geology, topography and bathymetry. Parts two, three and four are area specific field guides and commentary.
First published in 1985, Quaternary Environments represents the culmination of Quaternary research in the region of Baffin Island, Baffin Bay and West Greenland over a period of twenty years and it will serve as a timely and complementary balance to the paleo- oceanographic studies in the NE North Atlantic. The region of Baffin Island, Baffin Bay and West Greenland is probably the best place in the world to examine the interactions between ice, land and oceans on timescales of a few hundred to many thousands of years. Two introductory chapters outline the history of research and the physical background. In Part II the evidence for glacial erosion and deposition over the eastern Canadian Arctic is examined and the history of the Baffin Island continental shelf is described. Part III deals with the paleo- oceanography of Baffin Bay and the Labrador Sea through an examination of deep-sea cores dated by several different methods. In Part IV there is a comprehensive account of the stratigraphy of Baffin Island, Bylot Island, and West Greenland, from the Pliocene to the late Wisconsin. Part V examines the climatic effects of the past 10,000 years, considering evidence from pollen analysis, glacier fluctuations, changes of sea level and the response of early (Eskimo) man. This important volume will interest all quaternary scientists, especially those in glaciology, glacial geology, marine geology, and geomorphology.
The focus of this book is on oceanic climate change during the last deglaciation period and the high temporal resolution that can be obtained from sediment records at continental margin sites. The book draws together papers from the north-eastern North American continental margin with those from the north-west European Arctic and the Arctic and North Atlantic Oceans.
This volume had its origins in an international symposium organised by the Cold Regions Research Centre, and held at Wilfrid Laurier University in November, 1999. The chapters are modified from a selection of the papers at the meeting, and reflect reviews and revisions in light of discussions then. The original idea for the meeting was to address certain questions that the organisers were encountering in their own work, and that we felt had received limited attention in the recent literature. The two broad issues we wanted to address were: the complex associations of actual landforms and processes in cold regions, and how the almost universal legacies of past, different cold environments of the late Quaternary affect these landscapes in the present. The former involves the problem of identifying landform and sediment complexes, and the interrelations of relevant processes. We sought to identify this in terms oflandform and sediment assemblages appropriate to regional and field-oriented concerns.
The first paper in this compilation presents a brief history of geological exploration on southern Baffin Island. The second paper describes the geological framework of the Ordovician system in the south-east Arctic platform, Nunavut, and includes information on the stratigraphy & lithology of the Ordovician formations exposed on southern Baffin Island. The five remaining papers contain detailed paleontological descriptions of Ordovician fossils from that area, including algae, sponges, ostracoda, coral, echinoderms, brachiopods, mollusks, trilobites, conodonts, graptolites, and chitinozoans.
This volume examines the processes responsible for sedimentation in modern glaciomarine environments, and how such modern studies can be used as analogues in the interpretation of ancient glaciomarine sequences. Sediments released from glaciers grounded in tidewater, floating ice shelves, ice tongues, icebergs and sea ice form complex sequences governed by glaciological, oceanographic, sedimentary and biogenic controls. Ten per cent of the world's oceans and epicontinental seas contain such active glacimarine environments, but during Cenozoic glacial periods this area was doubled. This book will, therefore, be of relevance to all scientists concerned with high and middle latitude marine environments. The early chapters are concerned largely with processes of sedimentation in modern glacimarine environments; examples are drawn from Alaska, the Canadian Arctic, Svalbard and Antarctica. Studies of ancient sequences, both Cenozoic and pre-Cenozoic, from the Barents Sea, Greenland, Sweden, Alaska and the northwest European continental shelf, form the latter part of the book.
