This book was released on 2020-06-15 with total page 521 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coastal and estuarine environments at the interface of terrestrial and marine areas are among the most productive in the world. However, since the beginning of the industrial era, these ecosystems have been subjected to strong anthropogenic pressures intensified from the second half of the 20th century, when there was a marked acceleration in the warming (climate change) of the continents, particularly at high latitudes. Coastal ecosystems are highly vulnerable to alteration of their physical, chemical and biological characteristics (marine intrusion, acidification of marine environments, changes in ecosystems, evolution and artificialization of the coastline, etc.).In contact with heavily populated areas, these environments are often the receptacle of a lot of chemical and biological pollution sources that significantly diminish their resilience. In this context of accelerated evolution and degradation of these areas important for food security of many populations around the world, it is necessary to better identify the factors of pressure and understand, at different scales of observation, their effects and impacts on the biodiversity and on the socio-eco-systems, in order to determine the degree of vulnerability of these coastal ecosystems and the risks they face. A transdisciplinary and integrated approach is required to prevent risks. Within this framework, operational coastal oceanography occupies an important place but also the implementation of a true socio-eco-system approach in order to set up an environmentally friendly development.

Download or read book Visualizing Venice written by Kristin L. Huffman and published by Routledge. This book was released on 2017-10-04 with total page 259 pages. Available in PDF, EPUB and Kindle. Book excerpt: Visualizing Venice presents the ways in which the use of innovative technology can provide new and fascinating stories about places and times within history. Written by those behind the Visualizing Venice project, this book explores the variety of disciplines and analytical methods generated by technologies such as 3D images and interoperable models, GIS mapping and historical cartography, databases, video animations, and applications for mobile devices and the web. The volume is one of the first collections of essays to integrate the theory and practice of visualization technologies with art, architectural, and urban history. The chapters demonstrate how new methodologies generated by technology can change and inform the way historians think and work, and the potential that such methods have to revolutionize research, teaching, and public-facing communication. With over 30 images to support and illustrate the project’s work, Visualizing Venice is ideal for academics, and postgraduates of digital history, digital humanities, and early modern Italy.

Download or read book Clean Coastal Waters written by National Research Council and published by National Academies Press. This book was released on 2000-08-17 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental problems in coastal ecosystems can sometimes be attributed to excess nutrients flowing from upstream watersheds into estuarine settings. This nutrient over-enrichment can result in toxic algal blooms, shellfish poisoning, coral reef destruction, and other harmful outcomes. All U.S. coasts show signs of nutrient over-enrichment, and scientists predict worsening problems in the years ahead. Clean Coastal Waters explains technical aspects of nutrient over-enrichment and proposes both immediate local action by coastal managers and a longer-term national strategy incorporating policy design, classification of affected sites, law and regulation, coordination, and communication. Highlighting the Gulf of Mexico's "Dead Zone," the Pfiesteria outbreak in a tributary of Chesapeake Bay, and other cases, the book explains how nutrients work in the environment, why nitrogen is important, how enrichment turns into over-enrichment, and why some environments are especially susceptible. Economic as well as ecological impacts are examined. In addressing abatement strategies, the committee discusses the importance of monitoring sites, developing useful models of over-enrichment, and setting water quality goals. The book also reviews voluntary programs, mandatory controls, tax incentives, and other policy options for reducing the flow of nutrients from agricultural operations and other sources.

This book was released on 2012-12-06 with total page 555 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book arises from a NATO-sponsored Advanced Study Institute on 'The Role of Air-Sea Exchange in Geochemical Cycling' held at Bombann@§. near Bordeaux, France. from 16 to 27 September 1985. The chapters of the book are the written versions of the lectures given at the Institute. The aim of the book is to give a comprehensive up-to-date coverage of the subject. presented in a teaching mode. The chapters contain much recent research material and attempt to give the reader an understanding of how the role of air-sea exchange in geochemical cycling can be quantitatively assessed. In the last decade, major advances in the fields of marine and atmospheric chemistry have underlined the role of physical, chemical and biological processes at and near the air-sea interface in a number of geochemical cycles (C. S, N, metals etc ... ). Further, there is strong concern over the anthropogenic perturbation of these cycles on both regional and global scales. The first part of the book (Chapters 1 to 8) provides a review of topics fundamental to such studies. These topics include concepts in geochemical modelling, assessment of atmospheric transport from sources to the oceans. description of mixing and transport processes within the ocean for both dissolved and particulate materials, quantification of air-sea fluxes for both gases and particles, photochemical transformations in the atmospheric and oceanic boundary layers.

Available in PDF, EPUB and Kindle. Book excerpt: The cultivation of marine fish comes over the years gaining greater importance, based on the decline of fishing production and increased demand for this protein source. According to Ward and Myers (2005) in the past 50 years the fishing activity in high-scale in the oceans has interfered in the marine ecosystems, generating major ecological changes and dramatically reducing various fish stocks.Currently, due to growing demand for this type of food worldwide, there is a pressure on the scientific community and producers in search of improvements in the system and management. It is known that the main challenges today are fighting diseases, studies about the best place for the cultivation of a particular species, the search for replacement of protein source in the feed and breeding with the goal of finding the best features expressed by any species. Therefore, there is a huge field to evolve and develop the activity, which is relatively new when compared to other animal farming systems. In addition, an important factor to be considered with respect to the cultivation of marine fish is the legislation involved, which in most countries is an obstacle to the development of the activity due to high bureaucracy involved to acquire areas for production, especially in off-shore or near-shore systems.Some aspects are fundamental when it seeks to establish a marine fish farming, including the selection of species, area and cultivation system, the feed being used and your commercial availability, the availability of seed in the region, transportation and logistics, technologies employed in rearing, fattening and breeding, the knowledge of diseases and prophylactic and therapeutic treatments and funding and qualified personnel.This book is intended for professionals, students and researchers who are interested in meeting some aspects of the current situation of production of marine fishes worldwide.
