Field Methods in Marine Science: From Measurements to Models is an authoritative guide of the methods most appropriate for field research within the marine sciences, from experimental design to data analysis. Written for upper-level undergraduate and graduate students as well as early-career researchers, this textbook also serves as an accessible introduction to the concepts and practice of modeling marine system dynamics. This textbook trains the next generation of field scientists to move beyond the classic methods of data collection and statistical analysis to contemporary methods of numerical modeling; to pursue the assimilation and synthesis of information, not the mere recording of data. Boxes and side bars highlight important questions, interesting facts, relevant examples, and research techniques that supplement the text. Students and researchers alike will find the thorough appendices useful as a way of expanding comprehension of fundamental concepts.

This advanced textbook on modeling, data analysis and numerical techniques for marine science has been developed from a course taught by the authors for many years at the Woods Hole Oceanographic Institute. The first part covers statistics: singular value decomposition, error propagation, least squares regression, principal component analysis, time series analysis and objective interpolation. The second part deals with modeling techniques: finite differences, stability analysis and optimization. The third part describes case studies of actual ocean models of ever increasing dimensionality and complexity, starting with zero-dimensional models and finishing with three-dimensional general circulation models. Throughout the book hands-on computational examples are introduced using the MATLAB programming language and the principles of scientific visualization are emphasised. Ideal as a textbook for advanced students of oceanography on courses in data analysis and numerical modeling, the book is also an invaluable resource for a broad range of scientists undertaking modeling in chemical, biological, geological and physical oceanography.

Measurement And Modeling Of Polychlorinated Biphenyl Availability From Contaminated Sediment And Evaluation Of Ecosystem Recovery written by Elisabeth Marie-Louise Janssen and has been published by Stanford University this book supported file pdf, txt, epub, kindle and other format this book has been release on 2010 with categories.
This research comprises measurement and modeling of polychlorinated biphenyl (PCB) bioaccumulation from contaminated sediments and the evaluation of an in-situ sorbent amendment with activated carbon (AC) to allow ecosystem recovery. Laboratory bioassays with the deposit feeding polychaete Neanthes arenaceodentata, showed that PCB uptake from the aqueous phase accounted for less than three percent of the total uptake. High sediment ingestion rates and fast bioaccumulation of PCBs exceeding sediment concentration within 14 days of exposure suggest that deposit feeders are promising test organisms to evaluate local sediment conditions. A biodynamic model that described bioaccumulation by a mass balance approach of contaminant influx and efflux was parameterized for this polychaete. The model allows the prediction of tissue concentrations and facilitates the understanding of exposure pathways. Subsequently, the effects of an AC-amendment to sediment from a PCB-contaminated site at Hunters Point within the San Francisco Bay, California, were evaluated by employing caged deposit-feeders, along with polyoxymethylene (POM) samplers using parallel in situ and ex situ bioassays with homogenized untreated or AC-amended sediment. The AC-amendment reduced bioaccumulation by 90% in the laboratory and by 44% in parallel field tests with treated and untreated sediment. In-situ measurements with passive pore water samplers showed that PCB uptake was greater for samplers placed in the surface sediment compared to the underlying AC-amendment. The tests revealed three factors that influenced the in-situ bioassays: 1. AC-amendment significantly reduces bioavailability under laboratory and field conditions; 2. Deposit-feeding organisms exhibit less PCB uptake from untreated sediment when feeding is reduced; and 3. Sediment deposition within test cages in the field partially masks the benefit of underlying AC-amended sediment and emphasizes the need of area-wide considerations when assessing contaminated sediment management and remediation strategies. Parallel ex-situ and in-situ bioassays in combination with passive sampler measurements can tease apart field influences on PCB exposure. These tests should accompany each other to evaluate in-situ exposure and the effectiveness of remediation alternatives. This research further focused on pollution-induced changes of the benthic community at Hunters Point and the evaluation of the expected recovery potential after an AC-amendment for in-situ sediment remediation. The benthic community composition was compared for the PCB-contaminated site at Hunters Point and 30 reference sites in the San Francisco Bay to evaluate pollution-induced changes. Given the similar number of species, total abundance, and diversity indices between the reference sites and Hunters Point, it could be concluded that the benthic communities did not differ greatly. However, further analysis based on functional traits of the benthic community shows that the community at Hunters Point is deprived of species that may be stressed by the contaminated sediment due to their feeding mode, reproductive mode, or position in the sediment. The benthic community in comparison to reference sites lacks deposit feeders, subsurface carnivores, egg laying species, and species with no/weak protective barrier. Sediment chemistry analysis shows that PCBs are the major risk drivers at Hunters Point and that the reference sites show only ambient levels of PCB contamination. Biodynamic modeling demonstrates how varying exposure and functional feeding strategies affect PCB bioaccumulation, with a deposit feeder accumulating two orders of magnitude more PCBs in its lipids than a facultative deposit feeder and up to three orders of magnitude more than a filter feeder. Modeling scenarios also show that PCB tissue concentrations at Hunters Point are two orders of magnitude higher than at the reference sites. Sediment remediation with a sorbent (activated carbon) amendment at Hunters Point can reduce PCB availability by 85 to 90% under favorable field and treatment conditions. The expected remedial success corresponds to exposure conditions within sediment quality guidelines and the cleanup goal but remains slightly higher than at the reference sites.
