This book was released on 1986 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: Much of the suspended matter in the ocean exists as aggregates of organic detritus, living microorganisms and clay minerals. Historically, these aggregates have been categorized into the following two size classes: 1) marine snow, a general term describing amorphous suspended aggregates in the ocean larger than 500 um in size; and 2) microaggregates which range from a few microns up to 500 um in diameter. Both are primarily products of biological activity including mucus production, grazing, excretion, etc. In the open ocean, even those particles produced by physical/chemical coagulation processes (precipitation, particle collision, etc.) originate from largely biogenically derived component particles. Local loss terms include sinking, advection and decomposition which generally occur simultaneously with redistribution processes such as disaggregation, reingestion and defecation. Therefore, the dynamics of marine snow and microaggregates are functions of the actual aggregate properties, the biological processes and mechanisms which produce/redistribute them and physical/chemical process.

Download or read book Protozoa and Their Role in Marine Processes written by P.C. Reid and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 506 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the summer of 1988, under NATO sponsorship, approximately 80 scientists lived and worked together in Plymouth for two weeks to evaluate the ecological role of protozoa in the sea. Through the convivial surroundings, close working conditions and special facilities that had been brought together for NATO ASI 604/87 a 'melting pot' of ideas was formed, which stimulated the multidisciplinary creativity which is expressed in this book and in a second series of papers which will be published in Marine Microbial Food Webs under the title - "Protozoa and their Role in Marine Microbial Food Webs". Discussions of the role of protozoa in the microbial food web, in the cycling of carbon and nitrogen and the extent to which this web acts as a link or sink to metazoa in the water column were major themes of the ASI. Structured sessions covering oral and poster presentations, field work, model 1 ing, laboratory practicals and demonstrations of techniques such as image analysis and flow cytometry, formed the core of the meeting. Participants took part enthusiastically in the practical sessions developing new concepts and obtaining new insights into their work. The practicals included a 'protozoo' and some beautiful films and videos. Field excursions were made to a range of sites including a unique marine sewage farm at Looe in Cornwall, (Jones this volume). Interactive workshops allowed scientists with no modelling experience to input their results to three simulation models and a flow analysis package.

Download or read book Particle Dynamics in the Sea Processes of Production and Loss Governing the Abundance of Marine Snow written by and published by . This book was released on 1990 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: Much of the suspended particulate matter in the ocean exists as aggregates of smaller particles of algae, bacteria, organic detritus and inorganic particles. The characteristics and abundances of these aggregates affect trophic interactions, chemistry and optical properties of the water column. The goal of this research was to quantify several processes governing the rates of production, breakdown and loss of marine aggregates, particularly those larger than 500 um, known as marine snow. Our results indicate that gravitational settlement is considerably more significant than disaggregation as a process of aggregate loss. Settling velocities of natural aggregates measured directly in situ increased with increasing aggregate size and ranged from 50 to 200 md for aggregates up to 75mm in length. Moreover, aggregates were very strong and resistant to disaggregation by fluid shear. High energy storm events or current shears equivalent to those in tidal channels would be required to fragment even the most fragile organic aggregates in the upper ocean. The process of aggregate formation via particle collision and subsequent attachment occurs at rates up to an order of magnitude higher than previously assumed because the attachment probabilities of colliding marine snow aggregates approaches 100%. Coagulation of diatom blooms is a significant source of marine snow in many ocean regimes.

This book was released on 2008-06-05 with total page 880 pages. Available in PDF, EPUB and Kindle. Book excerpt: The proliferation of harmful phytoplankton in marine ecosystems can cause massive fish kills, contaminate seafood with toxins, impact local and regional economies and dramatically affect ecological balance. Real-time observations are essential for effective short-term operational forecasting, but observation and modelling systems are still being developed. This volume provides guidance for developing real-time and near real-time sensing systems for observing and predicting plankton dynamics, including harmful algal blooms, in coastal waters. The underlying theory is explained and current trends in research and monitoring are discussed.Topics covered include: coastal ecosystems and dynamics of harmful algal blooms; theory and practical applications of in situ and remotely sensed optical detection of microalgal distributions and composition; theory and practical applications of in situ biological and chemical sensors for targeted species and toxin detection; integrated observing systems and platforms for detection; diagnostic and predictive modelling of ecosystems and harmful algal blooms, including data assimilation techniques; observational needs for the public and government; and future directions for research and operations.

Download or read book Ocean Optics written by Rochard W. Spinrad and published by Oxford University Press. This book was released on 1994-01-06 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the publication of Jerlov's classic volume on optical oceanography in 1968, the ability to predict or model the submarine light field, given measurements of the inherent optical properties of the ocean, has improved to the point that model fields are very close to measured fields. In the last three decades, remote sensing capabilities have fostered powerful models that can be inverted to estimate the inherent optical properties closely related to substances important for understanding global biological productivity, environmental quality, and most nearshore geophysical processes. This volume presents an eclectic blend of information on the theories, experiments, and instrumentation that now characterize the ways in which optical oceanography is studied. Through the course of this interdisciplinary work, the reader is led from the physical concepts of radiative transfer to the experimental techniques used in the lab and at sea, to process-oriented discussions of the biochemical mechanisms responsible for oceanic optical variability. The text will be of interest to researchers and students in physical and biological oceanography, biology, geophysics, limnology, atmospheric optics, and remote sensing of ocean and global climate change.
