Studying the Ocean Planet requires measuring and sampling instruments to feed models that take into account its complexity. This book presents the diversity of observation and monitoring techniques at various scales, but also different kinds of model that take into account some conceptual schemes incorporating various scientific knowledge.
Sampling is approached via the efficiency of fishing gears; underwater acoustics is used to detect, count, identify and listen to live and mobile living resources. Bio-logging allows us to rely on the behavior of marine animals to help investigate environments that are difficult to sample by conventional means, while listing the physiological changes they undergo.
Modeling is presented not only in a functional framework, but also in an exploratory design incorporating various scenarios for ecosystem changes under the pressure of global change.
This ninth volume completes the "Seas and Oceans" Set that adopts a transversal approach leading to the governance and sustainable management of the marine environment.

Описание: The atmosphere may be our most precious resource. Accordingly, the balance between its use and protection is a high priority for our civilisation. While many of us would consider air pollution to be an issue that the modern world has resolved to a greater extent, it still appears to have considerable influence on the global environment. The radioactive pollution refers to the physical pollution of air, water and the other radioactive materials. The natural radiations are also known as the background radiations. In this the cosmic rays are involved and reach the surface of earth from space. It includes the radioactive elements like radium, uranium, thorium, radon, potassium and carbon. These occur in the rock, soil and water. The man made radiations include the mining and refining of plutonium and thorium. This production and explosion of nuclear weapons include the nuclear fuels, power plants and radioactive isotopes. Indoor air quality (IAQ) is a term which refers to the air quality within and around buildings and structures, especially as it relates to the health and comfort of building occupants. IAQ can be affected by gases (including carbon monoxide, radon, volatile organic compounds), particulates, microbial contaminants (mould, bacteria), or any mass or energy stressor that can induce adverse health conditions. Source control, filtration and the use of ventilation to dilute contaminants are the primary methods for improving indoor air quality in most buildings. Residential units can further improve indoor air quality by routine cleaning of carpets and area rugs. EPA has guidelines for frequency of cleaning based on traffic, number of household members, pets, children and smokers. Carpets and rugs act like an air filter and must be cleaned. Determination of IAQ involves the collection of air samples, monitoring human exposure to pollutants, collection of samples on building surfaces, and computer modelling of air flow inside buildings. Indoor air pollution in developing nations is a major health hazard globally. In many countries with ambitious economic growth targets the acceptable levels of air pollution have been transgressed. Serious respiratory disease related problems have been identified with both indoor and outdoor pollution throughout the world. This book deals with several air pollution issues air pollution chemistry; air pollutant emission control; radioactive pollution and d) indoor air quality.

Описание: A hull is the watertight body of a ship or boat. Above the hull is the superstructure and/or deckhouse, where present. The line where the hull meets the water surface is called the waterline. The structure of the hull varies depending on the vessel type. In a typical modern steel ship, the structure consists of watertight and non-tight decks, major transverse and watertight members called bulkheads, intermediate members such as girders, stringers and webs, and minor members called ordinary transverse frames, frames, or longitudinals, depending on the structural arrangement. The shape of the hull is entirely dependent upon the needs of the design. Shapes range from a nearly perfect box in the case of scow barges, to a needle-sharp surface of revolution in the case of a racing multihull sailboat. The shape is chosen to strike a balance between cost, hydrostatic considerations (accommodation, load carrying and stability), hydrodynamics (speed, power requirements, and motion and behavior in a seaway) and special considerations for the ships role, such as the rounded bow of an icebreaker or the flat bottom of a landing craft. The book provides an overview of cutting-edge developments in hybrid composite-metal marine ship hulls, covering the critical differences in material processing and structural behavior that must be taken into account to maximise benefits and performance. Supporting the design of effective hybrid hulls through proper consideration of the benefits and challenges inherent to heterogenic structures, the book covers specific details of quality control, manufacturing, mechanical and thermal stress, and other behavioural aspects that need to be treated differently when engineering hybrid ship hulls.

Описание: The fundamental characteristics of a ships design, and how they affect its behaviour at sea are of crucial importance to many people involved in the design, construction, operation, and maintenance of all marine vessels. Naval architects and those working in ship design need to understand these principles in depth. Marine engineers must likewise recognise the degree to which their activities are influenced and bounded by these principles. Naval architecture is an engineering discipline dealing with the engineering design process, shipbuilding, maintenance, and operation of marine vessels and structures. Naval architecture involves basic and applied research, design, development, design evaluation and calculations during all stages of the life of a marine vehicle. Preliminary design of the vessel, its detailed design, construction, trials, operation and maintenance, launching and dry-docking are the main activities involved. Knowledge of the fundamentals of naval architecture is essential not only for newcomers to the field but also the wealth of non-naval architects working in the marine area, including marine engineers, marine surveyors and ship crews. The book provides the most well-known and trusted introduction to the topic, offering a clear and concise take on the basics of this broad field. The book is ideal both for those approaching the subject for the first time and those looking to update or refresh their knowledge on areas outside of their direct expertise.

Описание: An aerosol is a colloidal system of solid or liquid particles in a gas. An aerosol includes both the particles and the suspending gas, which is usually air. Examples of natural aerosols are fog, forest exudates and geyser steam. Examples of artificial aerosols are haze, dust, particulate air pollutants and smoke. Atmospheric aerosols are solid or liquid particles or both suspended in air with diameters between about 0.002 m to about 100 m. Aerosol particles vary greatly in size, source, chemical composition, amount and distribution in space and time, and how long they survive in the atmosphere. Primary atmospheric aerosols are particulates that emitted directly into the atmosphere (for instance, sea-salt, mineral aerosols (or dust), volcanic dust, smoke and soot, some organics). Secondary atmospheric aerosols are particulates that formed in the atmosphere by gas-to-particles conversion processes (for instance, sulfates, nitrates, some organics). This book offers characterisation of atmospheric aerosols and their impact on regional climate. Detailed information about measurement techniques and atmospheric conditions were provided as well. The chemical and physical processes, temporal and spatial distribution, emissions, formation, and transportation of aerosol particles. The book should be of immense useful resource to resolve some of the issues associated with the complex nature of the interaction between atmospheric aerosols and climatology.

Описание: The analysis, design and construction of off-shore structures is arguably one of the most demanding sets of tasks faced by the engineering profession. Over and above the usual conditions and situations met by land-based structures, off-shore structures have the added complication of being placed in an ocean environment where hydrodynamic interaction effects and dynamic response become major considerations in their design. A basic understanding of a number of key subject areas is essential to an engineer likely to be involved in the design of offshore structures. This book provides a broad overview of some of the key factors in the analysis and design of offshore structures to be considered by an engineer uninitiated in the field of offshore engineering. Topics covered range from water wave theories, structure-fluid interaction in waves to the prediction of extreme values of response from spectral modeling approaches. It presents a new outlook on the measurement of wave forces on ocean structures, uniting the deterministic and probabilistic methodologies to wave theory and linking the methods used in field and experimental measurement.

Описание: Wetlands are the vital link between land and water. They support unique flora and fauna as well as provide ecological services that are beneficial to society Wetlands are among the most important and productive ecosystems on Earth. India is blessed with water resources and has a rich diversity of inland and coastal wetlands. Wetlands in India are distributed from the cold arid Trans-Himalayan zone to the wet Teri region of the Himalayan foothills, to the Gangetic plains extended to the flood-plains of Brahmaputra, and to the swamps of Northeastern India including the saline expanses of Gujarat and Rajasthan. This study is about three major natural wetlands of Eastern India: Sundarbans, Chilika and Kolleru. The Sundarbans is the largest mangrove forest in the world. It covers an area of about 1 m. ha. Sixty percent of this wetland is located in Bangladesh and the rest of the forty percent is in India. The Indian part of the Sundarbans is situated in the western part of the GangesBrahmaputra delta, and is extended from the Hooghly River in the west to the Raimangal River in the southeastern portion of the West Bengal State, spreading over two districts: North 24 Parganas and South 24 Parganas. The Chilika is the worlds second largest brackish water lagoon, and it is situated along the east coast of India in the state of Orissa on the Bay of Bengal with an area of 116,500 ha. The Chilika is extended over eight blocks of three districts; these districts are known as Ganjam, Khurda and Puri. This pear-shaped lake is about 64.5 km. long; its width varies from 18 km to 5 km. The water spread area of the lake varies from 906 sq.km to 1165 sq. km. depending upon the seasons. The Kolleru Lake is extended over the Krishna and West Godavari districts along the east coast of India in the state of Andra Pradesh. Kolleru is a large natural freshwater lake, with the catchment area being 4763 sq. km. Although the lake is about 35 km. inland from the present coast, it used to be a coastal lagoon in the past. Kolleru still maintains its connection with the Bay of Bengal through a 60 km long tidal channel called Upputeru. The average depth of the lake varies from 0.5 m. to 2.0m. This study offers a new sampling design; blocks in and around the specific wetland were stratified into three clusters, according to their distance from the specified wetland. Samples were chosen mostly from the blocks closest to the wetland, with minimal samples chosen from the blocks most distant from the wetland. Four different schedules were canvassed to four different groups of people: householders, entrepreneurs, tourists, and experts on wetlands. A new approach has been introduced for valuing the wetlands. This approach attempts to combine valuation of a wetland to the aforementioned groups of people. It also attempts to incorporate the valuation of the wetlands when used for other purposes.

Описание: Propulsion technology is a complex, multidisciplinary topic with design, construction, operational and research implications. A propeller is a rotating fan like structure which is used to propel the ship by using the power generated and transmitted by the main engine of the ship. The transmitted power is converted from rotational motion to generate a thrust which imparts momentum to the water, resulting in a force that acts on the ship and pushes it forward. Using propulsion forces, ships are able to manoeuvre themselves in the water. Initially while there were limited number of ship propulsion systems, in the present era there are several innovative ones with which a vessel can be fitted with. Today ship propulsion is not just about successful movement of the ship in the water. It also includes using the best mode of propulsion to ensure a better safety standard for the marine ecosystem along with cost efficiency. The book provides comprehensive and progressive coverage to furnish marine engineers, naval architects and anyone involved in propulsion and hydrodynamics with the knowledge needed to do the job. The book brings together a great range of knowledge on propulsion technology, a multi-disciplinary and international subject.
