Contourites are sediments deposited or substantially reworked by bottom currents. The study of contourites is crucial for several fields of fundamental and applied research: paleoclimatology and paleo-oceanography, since these fairly continuous and relatively high-resolution sediments hold the key for priceless information on the variability in circulation patter, current velocity, oceanographic history and basin interconnectivity; hydrocarbon exploration, since accumulation of source rocks may be favored by weak bottom currents, whereas "clean" deep-sea sands may be formed by robust flows; and slope stability, since low-permeability fine-grained contourites facilitate the formation of overpressurized gliding planes when fresh contourites with a high pore-water content becomes rapidly loaded, or when their rigid biosiliceous microfabric collapses due to diagenetic conditions. Despite its significance, this group of sediments is poorly known by the majority of non-specialists. Notwithstanding the growing interest and the intensified research in contourites, a textbook that might also serve as a reference book on contourites was missing until now. This book addresses all aspects of the knowledge in the field of contourites and provides an authoritative and comprehensive coverage of the subject. It also can serve as a standard reference work for non-specialists, and in particular postgraduate students, university teachers and lecturers, researchers and professionals who are seeking an authoritative source of information about contourites. * reviews both theoretical topics and case histories * provides practical advice on multidisciplinary research techniques * provides also nonspecialist users with an intuitively-accessible, cross-referenced, and comprehensive coverage of the knowledge in the field. * provides a helpful tool for research in the preparation of classroom lectures

There has lately been a growth in the number and level of studies of contourite deposits. Most recent studies of contourites have two major lines of interest. One, propelled by the oil industry's continuous move into increasingly deep waters, concerns their economic significance. The other involves the stratigraphic/ palaeoceanographic record of ocean circulation changes imprinted on contourite deposits that can be a key to understanding better the climate-ocean connection. The application of many different theoretical, experimental and empirical resources provided by geophysics, sedimentology, geochemistry, petrology, scale modeling and field geology are used in the 16 papers of this volume, proposing answers to those two main aspects. The papers are subdivided into two major categories (economic interest and stratigraphic/palaeoceanographic significance), with case studies ranging from well-documented drifts to new examples of modern and fossil series, involving a large diversity of geographic and physiographic scenarios worldwide

PATS-l is the first version of a package of computer programs and subroutines written or acquired specifically for the archiving, analysis, and presentation of marine micropaleontological data. The aim of this report is to document the procedures and programs incorporated in PATS-l and make them available to colleagues working on closely related research problems. The program package described in this report is not intended to be either comprehensive or generally useful. Rather, the PATS-l package was assembled for a specific purpose. It reflects the solutions to problems encountered in the course of my own work in micropaleontological oceanography. Some programs are so strictly tailored to my own research that they may have to be modified to be of any use to others. However, where convenient I have tried to generalize programs, especially in design of the subroutines incorporated into the PATS-l/LIBRARY. This report provides program listings, documentation, examples and instructions for implementation and use of the PATS-l package. Programs were written to be used interactively and at WHOI are run exclusively on the time-sharing system of the VAX ll/780 computer.
