This book was released on 2013-06-29 with total page 479 pages. Available in PDF, EPUB and Kindle. Book excerpt: A distinction between contamination and pollution is useful when we wish to consider what strategies to adopt in researching the impact of anthropogenic activities on the marine environment. Contamination strictly refers to the chemical burden imposed on the system and is evaluated in terms of the concentrations of chemical compounds in various abiotic (e. g water, suspended particulate matter, sediments) and biotic (plant and animal, pelagic and benthic) components. The concept of pollution, on the other hand, infers an assessment of biological response to the measured levels of contamination. This response may be measured at various levels of biological organisation, from molecular events within the cell to changes in such ecosystem properties as nutrient flux and biological productivity. Such measures of biological response need not infer any value judgements regarding putative damage or disturbance to the natural systems, although the biologist will usually have in mind a reference point of normality with which to compare the measured response; departure from this "normality" may then provide a quantitiative index of disturbance. The challenge to scientists engaged in research into marine contamination and pollution is to weld the chemical and biological elements together (always with reference also to the physical features of the environment) so as to provide a coherent framework for the quantitative evaluation of environmental response.

Available in PDF, EPUB and Kindle. Book excerpt: Many of the pollutants discharged into the sea are directly or indirectly the result of human activities. Some of these substances are biodegradable, while others are not. This study is devoted to monitoring areas of the environment. Methods assessment is based on monitoring data and an evaluation of the impact of pollution.Surveillance provides a scientific basis for standards development and application. The methodology of marine pollution control is governed by algorithms and models. A monitoring strategy should be put in place, coupled with an environmental assessment concept, through targeted research activities in areas identified at local and regional levels. This concept will make it possible to diagnose the state of "health" of these zones and consequently to correct any anomalies. Monitoring of the marine and coastal environment is based on recent methods and validated after experiments in the field of marine pollution.

Available in PDF, EPUB and Kindle. Book excerpt: The accuracy of chemical oceanographic measurements depends on calibration against reference materials to ensure comparability over time and among laboratories. Several key parameters lack reference materials for measurements in seawater, particles in the water column, and sediments. Without reference materials it is difficult to produce the reliable data sets or long-term baseline studies that are essential to verify global change and oceanic stability. Chemical Reference Materials : Setting the Standards for Ocean Science identifies the most urgently required chemical reference materials based on key themes for oceanographic research and provides suggestions as to how they can be developed within realistic cost constraints. Chemical analyses of seawater are uniquely difficult given the poorly known speciation and the low concentration of many of the analytes of interest. Analyses of suspended and sedimentary marine particulate materials present their own distinct challenges, primarily due to potential interference by predominant mineral phases of different types. Of all the analytical methods applied to marine waters and particles, at present only a small fraction can be systematically evaluated via comparison to reference materials that represent the appropriate natural concentrations and matrices. Specifically, the committee was charged with the following tasks: - compile from available sources a list of important oceanographic research questions that may benefit from chemical reference standards; - create a comprehensive list of reference materials currently available for oceanographic studies; - identify and prioritize the reference materials needed to study the identified research questions; - determine for each priority analyte whether reference materials and/or analytic methods should be standardized; and - identify the most appropriate approaches for the development and future production of reference materials for ocean sciences.
