Available in PDF, EPUB and Kindle. Book excerpt: Phytoplankton are the base of the marine food web. They are also responsible for much of the oxygen we breathe and they remove carbon dioxide from the atmosphere. The cause of seasonal phytoplankton blooms in the ocean is a debated topic. One hypothesis is that blooms are initiated when seasonally changing environmental conditions disrupt the balance in the predator-prey relationship between zooplankton and phytoplankton. This dissertation follows up on this notion with a Nutrient-Phytoplankton-Zooplankton (NPZ) model incorporating diffusion and depth-dependent coefficients. Full spatiotemporal solutions of this coupled reaction-diffusion system are computed. An explanation of the bloom process in this model is presented that involves a saddle point transient equilibrium state. The saddle point bloom process is demonstrated with an ordinary differential equations NPZ model with time dependent forcing to imitate seasonally oscillating solar radiation. This process is illustrated by an animation (movie1_ODE.avi). The details from this analysis inform the bloom process in the reaction-diffusion NPZ model for which the equilibria must be determined computationally. The bloom process in the reaction-diffusion NPZ model is illustrated by another animation (movie2_PDE.avi). The reaction-diffusion NPZ model, incorporated with seasonal solar radiation and mixed layer depth data, simulates blooms with better timing than the ordinary differential equations model but still leaves much to be desired. However, results from models that simulate blooms more accurately show signs of the saddle point bloom process described in this dissertation. The saddle point bloom mechanism described here could be the mechanism by which the seasonal disruption in ecological balance initiates a high-latitude marine phytoplankton bloom, like that in the North Atlantic Ocean.

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.

This book was released on 2013-05-09 with total page 1037 pages. Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 185. Indian Ocean Biogeochemical Processes and Ecological Variability provides a synthesis of current knowledge on Indian Ocean biogeochemistry and ecology and an introduction to new concepts and topical paradigm challenges. It also reports on the development of more extensive/frequent observational capacity being deployed in the Indian Ocean. This represents the first collection of syntheses that emphasize a basin-wide perspective, and the contributing authors include some of the most esteemed oceanographers and Indian Ocean experts in the world. The volume is derived from invited plenary talks that were presented at the initial Sustained Indian Ocean Biogeochemistry and Ecosystem Research (SIBER) workshop held at the National Institute of Oceanography (NIO) in Goa, India, in October 2006. The volume discusses The overlying physical processes set by monsoonal forcing and how these control biological production and variability Nutrient cycling and limitation Pelagic carbon cycling and air-sea exchange Benthic biogeochemistry and ecology The impact of climate and human activities on biogeochemistry and ecosystems. The readership for this book will consist of academic and governmental researchers interested in exploring how oceanographic, atmospheric, and hydrological processes combine to establish the environmental setting that supports and drives the pelagic system and which are especially relevant to understanding the complex biogeochemical and ecological interactions in the Indian Ocean.
