Book Description
The Code on noise levels on board ships has been developed to provide international standards for protection against noise under the provisions of regulation II-1/3-12 of the SOLAS Convention. The Code, adopted by resolution MSC.337(91), recognizes the need to establish mandatory noise level limits for machinery spaces, control rooms, workshops, accommodation and other spaces on board ships, and enters into force on 1 July 2014.The Code applies to new ships of a gross tonnage of 1,600 and above. The specific provisions relating to potentially hazardous noise levels, mitigation and personal protective gear contained in the Code may be applied to existing ships of a gross tonnage of 1,600 and above, as far as reasonable and practical, to the satisfaction of the Administration. The Code may be applied to new ships of a gross tonnage of less than 1,600 as far as reasonable and practical, to the satisfaction of the Administration. The Code includes: a format for noise survey reports; guidance on the inclusion of noise issues in safety management systems; - suggested methods of attenuating noise; and - a simplified procedure for determining noise exposure. These regulations, recommendations and advice are intended to provide Administrations with the tools to promote "hearing saving" environments on board ships. Although legally treated as a mandatory instrument under the SOLAS Convention, certain provisions of the Code remain recommendatory or informative.

Book Description
International cooperation on the health of seafarers began many years ago. As early as 1921, an international convention regarding this matter was presented to govern ments of maritime countries for ratification. The First World Health Assembly, in 1948, recommended that WHO should establish, with the International Labour Of fice, a Joint Committee on the hygiene of seafarers. The first session of this Com mittee, held in 1949, defined the problems affecting the health of seamen and made a number of recommendations. In the opinion of this Joint Committee, the health of seamen called for interna tional attention for a nu mb er of reasons. By the nature of his work, the seafarer is obliged to travel from country to country and is exposed to great variations of cli mate and also to any disease that may be prevalent in the port of call. He may there fore become a carrier of disease, so that the protection of his health is of importance not only to himself and the other members of the crew but also to the populations of other countries he visits. Yet, on account ofthe nature ofhis employment, it is diffi cult to provide the seafarer with the same standard of health care that is gene rally available to other sections of the population.

Book Description
The first International Symposium on Shipboard Acoustics, held in Noordwijkerhout (The Netherlands) in 1976, was a meeting of invited experts, each having considerable expertise in ship acoustics. Many of the participants were dealing with research on various ship acoustical subjects, and it proved to be a good idea to discuss future investigations and new techniques. At that time acousticians learned to use real-time signal-processing techniques and attempts were made to establish sound level prediction methods based on semi-fundamental considerations instead of the methods using empirically obtained data. Time was pressing as it was assumed that, in view of the adoption of Recommendation 141 of the International Labour Conference in 1970, authorities would soon make appropriate provisions to "protect seafarers from the ill effects of noise". This resulted in several national recommendations followed by the IMO "Code on noise levels aboard ships" which was adopted by the IMO Assembly in 1981. After that, pressure on the authorities was increased further by the decision of the European Community to protect labourers against harmful noise at their workplaces, including ships. Legally enforceable noise limits will therefore become normal in the future. In many countries recommendations with respect to maximum allowable sound pressure levels in the crew accomodations and work area aboard ships were already taken into account by ship owners, long before the existence of the Recommendations.

Book Description
For the 119 species of marine mammals, as well as for some other aquatic animals, sound is the primary means of learning about the environment and of communicating, navigating, and foraging. The possibility that human-generated noise could harm marine mammals or significantly interfere with their normal activities is an issue of increasing concern. Noise and its potential impacts have been regulated since the passage of the Marine Mammal Protection Act of 1972. Public awareness of the issue escalated in 1990s when researchers began using high-intensity sound to measure ocean climate changes. More recently, the stranding of beaked whales in proximity to Navy sonar use has again put the issue in the spotlight. Ocean Noise and Marine Mammals reviews sources of noise in the ocean environment, what is known of the responses of marine mammals to acoustic disturbance, and what models exist for describing ocean noise and marine mammal responses. Recommendations are made for future data gathering efforts, studies of marine mammal behavior and physiology, and modeling efforts necessary to determine what the long- and short-term impacts of ocean noise on marine mammals.

Book Description
Forest trees cover 30% of the earth's land surface, providing renewable fuel, wood, timber, shelter, fruits, leaves, bark, roots, and are source of medicinal products in addition to benefits such as carbon sequestration, water shed protection, and habitat for 1/3 of terrestrial species. However, the genetic analysis and breeding of trees has lagged behind that of crop plants. Therefore, systematic conservation, sustainable improvement and pragmatic utilization of trees are global priorities. This book provides comprehensive and up to date information about tree characterization, biological understanding, and improvement through biotechnological and molecular tools.
