Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Antarctic Research Series, Volume 57. Lakes of the dry valley region near McMurdo Sound, Antarctica, which are perennially ice-covered (approximately 4 m thick) and contain only microorganisms in the plankton, present unique systems for studies in hydrologic optics. Profiles of the flux and spectral distribution of photosynthetically available radiation (400-700 nm) and the optical properties of suspended particulate material were measured for Lake Bonney and Lake Fryxell.

Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Antarctic Research Series, Volume 17. Of the volumes currently available in the Antarctic Research Series, this volume is the fourth dealing with the biology of the antarctic seas. These collected papers comprise the results of original investigations, 11 of which are concerned mainly with the identification and distribution of marine plants and animals. In the first of these papers Stewart Springer gives a systematic appraisal of the five species of elasmobranch Rajidae from Antarctica, of which one represents a new and unique species. Heretofore one of the peculiarities of the antarctic ichthyological fauna has been the absence of sharks. In this very significant contribution, the author establishes the most southerly record for any member of the elasmobranchs. The second paper, by Patricia Kott, amplifies our systematic knowledge of the tunicates of the South Atlantic, South Pacific, and Indian oceans. It extends her monograph published as volume 13 of the Research Series under the title of Antarctic Ascidiacea and is based on collections made in the Antarctic through 1967; two new species are included. Additions and corrections to volume 13 are appended to this paper. John C. Markham reports on several lower chordates of the genus Cephalodiscus and discusses the systematics and distribution of the five species known from the Antarctic. The Deep Freeze materials examined in the course of this study were obtained through the U.S. Navy Hydrographic Office oceanographers from icebreakers assigned to task force 43 prior to and after the 1955–1959 International Geophysical Year and precede the National Science Foundation sponsored research now being conducted by the USNS Eltanin and the R/V Hero under the U.S. Antarctic Research Program.

This book was released on 2008 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are continual rounds of annual conferences, special sessions and other symposia that provide ample opportunity for researchers to convene and discuss igneous processes. However, the origin of laccoliths and sills continue to inspire and confound geologists. In one sense, this is surprising. After all, don't we know all we need to know about these rocks by now? As testified by the diverse range of topics covered in this volume, the answer is clearly 'no'. This book contains contributions on physical geology, igneous petrology, volcanology, structural geology, crustal mechanics and geophysics that cover the entire gambit of geological processes associated with the shallow emplacement of magma. High-level intrusions in sedimentary basins can also act as hydrocarbon reservoirs and as sources for thermal maturation. In drawing together a diversity of perspectives on the emplacement of sills, laccoliths and dykes we hope to advance further our understanding of their behaviour.
Download or read book The Transantarctic Mountains written by Gunter Faure and published by Springer Science & Business Media. This book was released on 2010-09-21 with total page 812 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a summary of the geology of the Transantarctic Mountains for Earth scientists who may want to work there or who need an overview of the geologic history of this region. In addition, the properties of the East Antarctic ice sheet and of the meteorites that accumulate on its surface are treated in separate chapters. The presentation ends with the Cenozoic glaciation of the Transantarctic Mountains including the limnology and geochemical evolution of the saline lakes in the ice-free valleys. • The subject matter in this book is presented in chronological order starting about 750 million years ago and continuing to the present time. • The chapters can be read selectively because the introduction to each chapter identifies the context that gives relevance to the subject matter to be discussed. • The text is richly illustrated with 330 original line drawings as well as with 182 color maps and photographs. • The book contains indexes of both subject matter and of authors’ names that allow it to be used as an encyclopedia of the Transantarctic Mountains and of the East Antarctic ice sheet. • Most of the chapters are supplemented by Appendices containing data tables, additional explanations of certain phenomena (e.g., the formation and seasonal destruction of stratospheric ozone), and illustrative calculations (e.g., 38Cl dates of meteorites). • The authors have spent a combined total of fourteen field seasons between 1964 and 1995 doing geological research in the Transantarctic Mountains with logistical support by the US Antarctic Program. • Although Antarctica is remote and inaccessible, tens of thousands of scientists of many nationalities and their assistants have worked there and even larger numbers of investigators will work there in the future.
