Paleoceanography
Whether in the context of off-shore oil exploration or pure research, the oceans of the geological past have never been of more compelling interest. The recent expansion in oceanographic studies has produced a burgeoning of data on ancient ocean circulation, climate, bathymetry, chemistry, biology, and temperature data that now should be considered in a more general geological and paleontological framework. Schopf has produced a remarkable synthesis of these data that provides any earth scientist with the background necessary to appreciate the history of the ancient oceans. Each of his seven chapters includes a summary of modern conditions, a major section on methods for determining ancient patterns, and a summary of each oceanographic factor over geological time. Paleoceanography will serve as an important resource for paleontologists and for a much broader audience of earth and ocean scientists, petroleum geologists, and stratigraphers.
Use of Proxies in Paleoceanography
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....

Proxies in Late Cenozoic Paleoceanography
The present volume is the first in a series of two books dedicated to the paleoceanography of the Late Cenozoic ocean. The need for an updated synthesis on paleoceanographic science is urgent, owing to the huge and very diversified progress made in this domain during the last decade. In addition, no comprehensive monography still exists in this domain. This is quite incomprehensible in view of the contribution of paleoceanographic research to our present understanding of the dynamics of the climate-ocean system. The focus on the Late Cenozoic ocean responds to two constraints. Firstly, most quantitative methods, notably those based on micropaleontological approaches, cannot be used back in t...
Paleoecology, Biostratigraphy, Paleoceanography and Taxonomy of Agglutinated Foraminifera
Agglutinated foraminifera are among the most widely distributed and abundant groups of marine meiofauna in some environments (e. g. marshes, deep-sea). They are tolerant of environmental extremes, tending to live where the evolutionarily more advanced calcareous foraminifera cannot survive. However, largely because of historical reasons, the amount of scientific effort invested in this group has been small in comparison to studies of other marine organisms. The NATO Advanced Studies Institute conference on the paleoecology, biostratigraphy, paleoceanography and taxonomy of agglutinated foraminifera in TUbingen September 17-29, 1989, was a direct outgrowth of two previous workshops on aggluti...
The South China Sea
Pinxian Wang and Qianyu Li The South China Sea (SCS) (Fig. 1. 1) offers a special attraction for Earth scientists world-wide because of its location and its well-preserved hemipelagic sediments. As the largest one of the marginal seas separating Asia from the Paci?c, the largest continent from the largest ocean, the SCS functions as a focal point in land-sea int- actions of the Earth system. Climatically, the SCS is located between the Western Paci?c Warm Pool, the centre of global heating at the sea level, and the Tibetan Plateau, the centre of heating at an altitude of 5,000m. Geomorphologically, the SCS lies to the east of the highest peak on earth, Zhumulangma or Everest in the Himalayas...
Quaternary Stratigraphy and Paleoceanography of the Canada Basin, Western Arctic Ocean
Climate and paleoceanography of the western Arctic Ocean for the last 1 million years interpreted from our four marine sediment cores.
Micropaleontology
Discusses the application of microfossils in stratigraphy and paleoceanography. The book covers geological time from Proterozoic to Cenozoic, deep sea hiatuses, global carbon cycles, ocean circulation and related climate changes, extraterrestrial events, upwelling and productivity, and more.
