Available in PDF, EPUB and Kindle. Book excerpt: Paleoceanographic proxies provide infonnation for reconstructions of the past, including climate changes, global and regional oceanography, and the cycles of biochemical components in the ocean. These prox ies are measurable descriptors for desired but unobservable environmental variables such as tempera ture, salinity, primary productivity, nutrient content, or surface-water carbon dioxide concentrations. The proxies are employed in a manner analogous to oceanographic methods. The water masses are first characterized according to their specific physical and chemical properties, and then related to particular assemblages of certain organisms or to particular element or isotope distributions. We have a long-standing series of proven proxies available. Marine microfossil assemblages, for instance, are employed to reconstruct surface-water temperatures. The calcareous shells of planktonic and benthic microorgan isms contain a wealth of paleoceanographic information in their isotopic and elemental compositions. Stable oxygen isotope measurements are used to detennine ice volume, and MglCa ratios are related to water temperatures, to cite a few examples. Organic material may also provide valuable infonnation, e. g. , about past productivity conditions. Studying the stable carbon isotope composition of bulk organic matter or individual marine organic components may provide a measure of past surface-water CO 2 conditions within the bounds of certain assumptions. Within the scope of paleoceanographic investigations, the existing proxies are continuously evolving and improving, while new proxies are being studied and developed. The methodology is improved by analysis of samples from the water column and surface sediments, and through laboratory experiments.

Book excerpt: The Jurassic of Denmark and adjacent areas occurs mostly in the subsurface and research has thus focussed on the wealth of borehole and reflection seismic data resulting from over thirty years of hydrocarbon exploration. The Jurassic of East Greenland, in contrast, is exposed in spectacular cliffs along fjords and mountainsides and has come to be regarded as a unique field laboratory, particularly amongst those working on the Norwegian shelf--the conjugate margin of East Greenland. This bulletin presents the results of a period of intensive research into the Jurassic in the late 1980s and 1990s. Following detailed chronostratigraphic and biostratigraphic reviews of the Jurassic of Northwest Europe, the successions of Denmark and East Greenland are subjected to a range of stratigraphic, sedimentological, structural and geochemical studies that together provide the basis for a detailed comparison of the Jurassic evolution of the East Greenland and Danish sedimentary basins.

Available in PDF, EPUB and Kindle. Book excerpt: Quaternary geology is the study of the most recent period of geological time, looking at the Earth in terms of its development as a planet. This books examines the history of its life forms, the materials of which it is made, processes that affect these materials, and products that are formed from them.

Download or read book The Vegetation of Poland written by Władysław Szafer and published by Elsevier. This book was released on 2013-10-02 with total page 774 pages. Available in PDF, EPUB and Kindle. Book excerpt: International Series of Monographs in Pure and Applied Biology, Volume 9: The Vegetation of Poland focuses on the plant geography of Poland, including climate, hydrography, geology, and ecology. The selection first offers information on the historical outline of the development of plant geography and the factors affecting the geographical distribution of plants in Poland. Discussions focus on the development of phytogeographical cartography, floristic and ecological plant geography, and the climate, boundaries, land-relief, hydrography, and geology of Poland. The text then ponders on the influence of man and his economic activities on the vegetation of Poland and the floristic statistics and the elements of the Polish flora. The publication examines the terrestrial and fresh-water plant communities and vegetation of the Polish Baltic. Topics include composition and structure of plant communities and methods of their study, associations of coastal and inland dunes, aquatic and swamp associations, and the most important representatives of the benthic flora of the Polish Baltic. The manuscript is a dependable source of data for botanists and those concerned with the plant resources of nature, including agriculturists, horticulturists, and soil scientists.
