Numerical Models of Underwater Acoustic Propagation,n automated computer code capable of being executed by someone other than the originator for a wide variety of problems. No single model currently exists which is adequate for all applications. This is perhaps not surprising considering the diversity of the ocean environment and its boundaries, and 作者: Morphine 時(shí)間: 2025-3-22 06:42
Physical Modeling of Underwater Acoustics,veloped. These include, but are not limited to, mathematical analysis, numerical modeling, in situ empirical description, and physical modeling. All have made substantial contributions to our understanding of the way in which sound behaves in water. The purpose of this chapter is to review the metho作者: intuition 時(shí)間: 2025-3-22 11:00
Oceanography in Underwater Acoustics,ctions, after a discussion of the important physical parameters, follows the scales of variations that exist in the ocean. First, the oceanic “climate” that is represented by mean ocean basin scale conditions with its seasonal changes is presented. Then, the ocean “weather” that is represented by ed作者: Wallow 時(shí)間: 2025-3-22 12:54
Acoustic Probing of Space-Time Scales in the Ocean,derate our weather. The Gulf Stream changes shape and location in rough approximation to the seasons. The weather on the East Coast of the United States may worsen significantly if the stream moves further offshore. These circulating waters also carry nutrients essential to the maintenance of fishin作者: 遺忘 時(shí)間: 2025-3-22 17:26
Numerical Models of Underwater Acoustic Propagation, of the wave equation found in Sect.2.2.1. Fundamentally these models consider the ocean to be a deterministic environment for which the speed of sound is only a function of the spatial coordinates. Non-deterministic effects, if accounted for at all, are included in an ad hoc fashion following the d作者: Customary 時(shí)間: 2025-3-23 00:30
Physical Modeling of Underwater Acoustics,anks and particularly with the study of surface scattering in such facilities. Physical model research has been conducted for some time in a number of contexts. Unfortunately, until the present there has been little communication among various investigators on matters of technique.

Introduction,d, and the relationship can be expressed mathematically. The second and more recent aspect is concerned with the use of acoustics as a tool to prove the oceanic structure. For example, acoustics can be used to monitor ocean currents in the sense that characteristic modifications of the acoustic field infer local changes in the ocean current.作者: Connotation 時(shí)間: 2025-3-23 13:53
Oceanography in Underwater Acoustics,ention. Next, the subjects of internal waves and fine structure representing horizontal scales of tens of meters to order ten kilometers are presented. Finally, we include a short discussion of the scales of variability in the near-surface mixed layer.作者: 減震 時(shí)間: 2025-3-23 20:46
Theoretical Methods in Ocean Acoustics,first describe the properties of the fluid equations. We derive equations for these properties in Sect.2.1 from first principles, but briefly, and then obtain the equations governing the sound field which we discuss in more detail in the remaining parts of this chapter.作者: Fallibility 時(shí)間: 2025-3-23 23:16 作者: engrave 時(shí)間: 2025-3-24 04:45 作者: deriver 時(shí)間: 2025-3-24 08:31 作者: conceal 時(shí)間: 2025-3-24 12:24 作者: 認(rèn)識(shí) 時(shí)間: 2025-3-24 17:48
