Since the sound wave is the only information carrier that can propagate long distances in the ocean, underwater acoustic technology based on sound waves undoubtedly plays an important role in ocean observation. The development of underwater acoustic technology requires the support of various underwater acoustic sensors and signal processing techniques. The function of an underwater acoustic sensor is to conduct the conversion between an underwater acoustic signal and an electric signal. Their performance directly determines the quality of underwater acoustic equipment. However, the harsh environment such as high pressure, high temperature, and highly corrosive fluids, as well as different requirements such as low frequency, broad bandwidth, high power, and deep water, often affect the physical properties of materials and structural performance of transducers, which deteriorates the transducer performance. Due to the lack of comprehensive research on key techniques including material physical properties and interfacial bond properties, the reliability of structural components is often seriously affected by environmental conditions, which may lead to major performance degradation or even failure with the device performance. Therefore, it is challenging for the transducer design to balance the acoustic performance and the device's stability.

The interaction of acoustic fields with submerged elastic structures, both by propagation and scattering, is being investigated at various institutions and laboratories world-wide with ever-increasing sophistication of experiments and analysis. This book offers a collection of contributions from these research centers that represent the present state-of-the-art in the study of acoustic elastic interaction, being on the cutting edge of these investigations. This includes the description of acoustic scattering from submerged elastic objects and shells by the Resonance Scattering Theory of Flax, Dragonette and Überall, and the interaction of these phenomena in terms of interface waves. It also includes the use of this theory for the purpose of inverse scattering, i.e. the determination of the scattered objects properties from the received acoustic backscattered signals. The problem of acoustically excited waves in inhomogeneous and anisotropic materials, and of inhomogeneous propagating waves is considered. Vibrations and resonances of elastic shells, including shells with various kinds of internal attachments, are analyzed. Acoustic scattering experiments are described in the time domain, and on the basis of the Wigner-Ville distribution. Acoustic propagation in the water column over elastic boundaries is studied experimentally both in laboratory tanks, and in the field, and is analyzed theoretically. Ultrasonic nondestructive testing, including such aspects like probe modelling, scattering by various types of cracks, receiving probes and calibration by a side-drilled hole is also studied in details.A comprehensive picture of these complex phenomena and other aspects is presented in the book by researchers that are experts in each of these domains, giving up-to-date accounts of the field in all these aspects.

Ocean engineering is generally considered to be concerned with studies on the effects of the ocean on the land and with the design, construction and operation of vehicles, structures and systems for use in the ocean or marine environment. The practice of engineering differs from that of science in both motivations and objectives. Science seeks understanding of the principles of nature in terms of generalizations expressed as laws and classifications. Engineering seeks the application of knowledge of the physical and natural world to produce a benefit expressed as a device, system, material, and/or process. From the standpoint of the financial sponsors of an engineering project, the ideal approach is one of minimal risk in which only proven knowledge, materials and procedures are employed. There is frequent departure from this ideal in anticipation of the increased benefit expected from a large increase in performance of a structure or device. The process of acquiring this new capability is engineering research. Historically, ocean engineering developed with the application of engineering principles and processes to the design of ships and, later, to the machinery that propels them. In most societies, naval architecture and marine engineering are recognised as the origin of ocean engineering. In fact, the design of a ship constitutes the original systems engineering programme involving hydrodynamics/fluid flow, structural design, machinery design, electrical engineering and so on as well as requiring knowledge of the ocean environment (waves, corrosion, etc.).

This Research Topic is the second volume of this collection. You can find the original collection via https://www.frontiersin.org/research-topics/45485/deep-learning-for-marine-science Deep learning (DL) is a critical research branch in the fields of artificial intelligence and machine learning, encompassing various technologies such as convolutional neural networks (CNNs), recurrent neural networks (RNNs), Transformer networks and Diffusion models, as well as self-supervised learning (SSL) and reinforcement learning (RL). These technologies have been successfully applied to scientific research and numerous aspects of daily life. With the continuous advancements in oceanographic observation equipment and technology, there has been an explosive growth of ocean data, propelling marine science into the era of big data. As effective tools for processing and analyzing large-scale ocean data, DL techniques have great potential and broad application prospects in marine science. Applying DL to intelligent analysis and exploration of research data in marine science can provide crucial support for various domains, including meteorology and climate, environment and ecology, biology, energy, as well as physical and chemical interactions. Despite the significant progress in DL, its application to the aforementioned marine science domains is still in its early stages, necessitating the full utilization and continuous exploration of representative applications and best practices.

With unprecedented attention on global change, the current debate revolves around the availability and sustainability of natural resources and how to achieve equilibrium between what society demands from natural environments and what the natural resource base can provide. A full understanding of the range of issues, from the consequences of the changing resource bases to the degradation of ecological integrity and the sustainability of life, is crucial to the process of developing solutions to this complex challenge. Authored by world-class scientists and scholars, The Encyclopedia of Natural Resources provides an authoritative reference on a broad spectrum of topics such as the forcing factors and habitats of life; their histories, current status, and future trends; and their societal connections, economic values, and management. The content presents state-of-the-art science and technology development and perspectives of resource management. Written and designed with a broad audience in mind, the entries clearly elucidate the issues for readers at all levels. In Volume II, Water includes 59 entries and Air includes 31 entries. The Water entries cover topical areas such as fresh water, groundwater, water quality and watersheds, ice and snow, coastal environments, and marine resources and economics. The Air entries cover air pollutants, atmospheric oscillation, circulation patterns and atmospheric water storage, as well as agroclimatology, climate change, and extreme events. Additional topics in meteorology include acid rain, drought, ozone depletion, water storage, and more. Natural resources represent such a broad scope of complex and challenging topics that a reference book must cover a vast number of subjects in order to be titled an encyclopedia. The Encyclopedia of Natural Resources does just that. The topics covered help readers face current and future issues in the maintenance of clean air and water as well as the preservation of land resources and native biodiversity. Also Available Online This Taylor & Francis encyclopedia is also available through online subscription, offering a variety of extra benefits for researchers, students, and librarians, including: Citation tracking and alerts Active reference linking Saved searches and marked lists HTML and PDF format options Contact Taylor and Francis for more information or to inquire about subscription options and print/online combination packages.
