As we discover more about the role of the ocean in global changes and identify the effects of global change on the ocean, understanding its chemical composition and processes becomes increasingly paramount. However, understanding these processes requires a wide range of measurements in the vast ocean, from the sea surface to deep-ocean trenches, fr

Two types of small (30-cm aperture) sheet metal sediment traps were developed to monitor onslope surface sediment transport. Traditionally, sediment traps and erosion pins have been used to measure the onslope movement of surficial soil material. While pins may be appropriate for documentinglandscapedenudation, traps aremoresuitable for monitoring downslope transport parallel to the ground surface. Previous investigations used large (3-m aperture) traps to measure sediment transport. However, large aperture traps are cumbersome and require excessive amounts of time and energy for installation, sample collection, and sample processing. These serious logistical constraints make data acquisition difficult and expensive. The small traps were designed to remedy this situation. Reld tests of these small traps revealed variable patterns of spatial and temporal surficial debris movement obscured in previous studies. Although these traps are not without limitations, the improved sampling logistics allow greater sample sizes andconstituteamarkedimprovement over other transport measurement techniques.

Onondaga Lake in Syracuse, New York is a model for the analysis and management of a polluted urban lake. Sometimes referred to as "the most polluted lake in the United States", Onondaga Lake is one of only two lakes for which a federal advisory body has been set up to guide environmental remediation. The recipient of significant municipal effluent and industrial waste for more than a century, Onondaga Lake has been the focus of intensive limnological investigation and extensive remediation efforts. This book is a comprehensive presentation of the scientific knowledge about Onondaga Lake, based on research coordinated by the Upstate Freshwater Institute. Onondaga Lake: Limnology and Environmental Management of a Polluted Urban Lake is the most complete case study of a lake, and will be of interest to water quality scientists, engineers and managers, as well as environmental engineers, modelers, and policymakers.

Since the book first appeared in 1976, Methods of Seawater Analysis has found widespread acceptance as a reliable and detailed source of information. Its second extended and revised edition published in 1983 reflected the rapid pace of instrumental and methodological evolution in the preceding years. The development has lost nothing of its momentum, and many methods and procedures still suffering their teething troubles then have now matured into dependable tools for the analyst. This is especially evident for trace and ultra-trace analyses of organic and inorganic seawater constituents which have diversified considerably and now require more space for their description than before. Methods to determine volatile halocarbons, dimethyl sulphide, photosynthetic pigments and natural radioactive tracers have been added as well as applications of X-ray fluorescence spectroscopy and various electrochemical methods for trace metal analysis. Another method not previously described deals with the determination of the partial pressure of carbon dioxide as part of standardised procedures to describe the marine CO2 system.

Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 63. In the past twenty or so years, there has been an increasing amount of interest in suspended particulates in seawater. This interest has concentrated on defining the distribution and variance of particle mass, composition, and flux. It is now well recognized that biogenic and other particle fluxes in the ocean define the principle mechanisms of non-conservative behavior that influence all reactive material. There is, however, concern that the analytical and sampling variability associated with our methods must be sufficiently within our control in order to discern important temporal and spatial variability of particles and fluxes. A review of papers in the recent literature which deal with analyzing the chemical and physical properties of particles collected by traps, pumps and other samplers, reveals that there is a considerable diversity of approaches and techniques being used by the community of active researchers in this field.
