Investigating Seafloors And Oceans

Investigating Seafloors and Oceans: From Mud Volcanoes to Giant Squid offers a bottom-to-top tour of the world’s oceans, exposing the secrets hidden therein from a variety of scientific perspectives. Opening with a discussion of the earth’s formation, hot spots, ridges, plate tectonics, submarine trenches, and cold seeps, the text goes on to address such topics as the role of oceans in the origin of life, tidal bore, thermal effects, ecosystem services, marine creatures, and nutraceutical and pharmaceutical resources. This unique reference provides insight into a wide array of questions that researchers continue to ask about the vast study of oceans and the seafloor. It is a one-of-a-kind examination of oceans that offers important perspectives for researchers, practitioners, and academics in all marine-related fields. Includes chapters addressing various scientific disciplines, offering the opportunity for readers to gain insights on diverse topics in the study of oceans Provides scientific discussion on thermo-tolerant microbial life in sub-seafloor hot sediments and vent fields, as well as the origin of life debates and the puzzles revolving around how life originated Includes detailed information on the origin of dreaded episodes, such as volcanic eruptions, earthquakes, tsunamis, internal waves and tidal bores Contains information on the contribution of the oceans in terms of providing useful nutraceutical and pharmaceutical products

Measuring Ocean Currents: Tools, Technologies, and Data covers all major aspects of ocean current measurements in view of the implications of ocean currents on changing climate, increasing pollution levels, and offshore engineering activities. Although more than 70% of the Earth is covered by ocean, there is limited information on the countless fine- to large-scale water motions taking place within them. This book fills that information gap as the first work that summarizes the state-of-the-art methods and instruments used for surface, subsurface, and abyssal ocean current measurements. Readers of this book will find a wealth of information on Lagrangian measurements, horizontal mapping, imaging, Eulerian measurements, and vertical profiling techniques. In addition, the book describes modern technologies for remote measurement of ocean currents and their signatures, including HF Doppler radar systems, satellite-borne sensors, ocean acoustic tomography, and more. Crucial aspects of ocean currents are described in detail as well, including dispersion of effluents discharged into the sea and transport of beneficial materials—as well as environmentally hazardous materials—from one region to another. The book highlights several important practical applications, showing how measurements relate to climate change and pollution levels, how they affect coastal and offshore engineering activities, and how they can aid in tsunami detection. Coverage of measurement, mapping and profiling techniques Descriptions of technologies for remote measurement of ocean currents and their signatures Reviews crucial aspects of ocean currents, including special emphasis on the planet-spanning thermohaline circulation, known as the ocean's "conveyor belt," and its crucial role in climate change

A beautifully illustrated reference providing fascinating insights into the hidden world of the seafloor using the latest deep-sea imaging.

This book is a resource manual and guide that will help students learn about the oceans, explore some of the major phenomena that occur on our planet, and appreciate the way that scientific investigation of the Earth proceeds. The book is divided into two parts. The first part contains a series of short investigations that are designed to help students learn about a particular topic. Thirty-seven short exercises deal with the many aspects of oceanography and have been put into a laboratory format and can easily be torn out and handed in for homework. The second part of the text provides a concise overview of major concepts of oceanography, which can serve as an additional resource to help students interpret the workings of the oceanic system.

The book looks at the need of minerals for humanity, how and what the oceans offer as minerals in general, the technological developments achieved and the insight into future technologies and designs in this field before finally focusing on the mineral wealth of the Indian Ocean. It eventually poses some tough questions that need answers if deep seabed mining is to become a success in the future. In addition, it discusses the efforts of the key players in this field operating in the Indian ocean that has rejuvenated the deep seabed mining both economically and strategically. Since, commercial profitability of marine minerals occurs only if the demand is greater than the supply, at times, the decision gets governed by strategic reasoning. Hence, the book aims to give an idea of the driving forces that guide such decision-making and the development of deep seabed mining.

Water Worlds in the Solar System: In Search of Habitable Environments and Life is a comprehensive reference on the formation, availability, habitability potential, and astrobiological implications of water in the Solar System. The book provides understanding of the importance of water on Earth to elucidate potential water and biosignature sources on other bodies in the Solar System. It covers processes involved in the formation of Earth and its Moon, genesis of water on those bodies, events on early Earth, and other processes that are applicable to celestial bodies in the Solar System, directly correlating data available on water on other bodies to over 15 Earth analogue sites. This book forms a comprehensive overview on water in the Solar System, from formation to biosignature and habitability considerations. It is ideal for academics, researchers and students working in the field of planetary science, extraterrestrial water research and habitability potential. Presents a comprehensive reference on water in the Solar System, developing readers’ understanding of the importance and occurrence of water on Earth and beyond, all from an oceanographer’s perspective Contrasts terrestrial analogues in relation to their roles in understanding and exploring ocean worlds and habitability Includes numerous figures, illustrations, tables and videos to help readers better understand concepts covered

Elements of Marine Ecology, Fifth Edition focuses on marine ecology as a coherent science, providing undergraduate students with an essential foundation of knowledge in the structure and functioning of marine ecosystems. The text reflects ecological groupings such as the pelagic lifestyle vs. the benthic lifestyle. In addition, background oceanographic material, previously in various chapters, is consolidated in the first chapter. The broad definition of ecology is the study of organisms in relation to their surroundings. This book presents marine ecology as a coherent science, providing undergraduate students with an essential foundation of knowledge in the structure and functioning of marine ecosystems. This new edition has been thoroughly revised and updated to meet the needs of today’s courses and now includes worldwide examples, all thoroughly updated with brand new chapters. Presents marine ecology as a coherent science, providing undergraduate students with an essential foundation of knowledge on the structure and functioning of marine ecosystems Includes fully updated, color images to enhance the text Provides a new chapter on Marine Nekton to increase coverage of habitat and ecology of water column organisms
