In later life the recipient of the Nobel Peace Prize for his humanitarian work, the explorer and scientist Fridtjof Nansen (1861 1930) encouraged and supported the 1901 voyage of his fellow Norwegian Roald Amundsen (1872 1928), publishing this account of its scientific findings in 1906. Amundsen had just purchased his famous boat, the Gjoa, and wanted to test her in Arctic waters. He planned to pay for the expedition by hunting seals, but wanted to carry out scientific work at the same time. On Nansen's advice, he decided to make oceanographic observations. After a six-month voyage, he returned with both observations and samples of water and plankton which considerably enlarged understanding of the bottom waters of the Norwegian Sea and the play of current in the area. Nansen's work supplies technical details, diagrams and maps from this remarkable scientific survey."

In this wide-ranging and comprehensive review of the historical development and current status of ocean circulation models, the analysis extends from simple analytical approaches to the latest high-resolution numerical models with data assimilation. The authors, both of whom are pioneer scientists in ocean and shelf sea modelling, look back at the evolution of Western and Eastern modelling methodologies during the second half of the last century. They also present the very latest information on ocean climate modelling and offer examples for a number of oceans and shelf seas.

The book includes a critical analysis of literature on ocean climate variability modelling, as well as assessing the strengths and weaknesses of the best-known modelling techniques. It also anticipates future developments in the field, focusing on models based on a synthesis of numerical simulation and field observation, and on nonlinear thermodynamic model data synthesis.

Hurricanes are nature's most destructive agents. Widespread interest surrounds the possibility that they might get even more destructive in the future. Policy makers consider it a call for action. Answers about when and by how much hurricanes will change are sought by financial institutions especially industry. And scientists are challenged by the range and interactions of the processes involved. This book, arising from the 2nd International Summit on Hurricanes and Climate Change, contains new research on topics related to hurricanes and climate change since the 1st Summit. Chapters are grouped into research studies using global climate models and those taking empirical and statistical approaches. The latter include investigations of basin-wide and regional hurricane activity.

Case studies focus on applications of artificial neural networks, evolutionary computation, cellular automata, adaptive agents, fuzzy logic as well as qualitative reasoning. The 2nd edition of the book includes an index with novel evolutionary algorithms for the discovery of multiple nonlinear functions and rule sets as well as parameter optimisation in complex ecological data.

One key uncertainty in predictions of future climate is caused by the lack of knowledge of transport processes in the air-water interface; this poses the main transfer resistance between oceans and atmosphere. This book reviews recent progress in the domains of experimental process studies as well as computer stimulation. It represents an early approach of merging insights gained in both fields and broadens our understanding of air-water gas and heat exchange.

Renewable energy resources now play an essential role in the energy supply debate, and especially a new interest in wind energy has resulted in the intensified construction of wind farms. Thanks to the growing demand for renewable energy, offshore wind farms (OWFs) are increasingly gaining in popularity, since yields over sea are greater and more reliable than over land. Against this background it is becoming particularly urgent to determine whether and if so to what extent such OWF expansion affects our oceans and local climates. OWFs produce a downstream wind speed reduction, the so-called wind-wake effect, which impacts atmospheric boundary layers, alters local wind characteristics and in turn affects ocean dynamics. This book will help readers to understand in detail these OWF-induced changes in the atmosphere and ocean by analyzing model simulations and measurements. In this context, OWF-induced upwelling and downwelling are key aspects.

It all began with Markus Jochum approaching one of us (HvS) - "when you guys are doing interviews with senior scientists from oceanography and related sciences, why are you not doing Walter Munk?" Indeed, why not? Walter Munk, an icon in oceanography, had just given a wonderful talk in a symposium in honor of his 90th birthday, sweeping a grand circle from his earliest work with Chip Cox on airborne measurements of ocean surface roughness to the latest satellite data - not simply a review, but the struggle of an active scientist opening up new perspectives - as inspiring and stimulating as when one of us (KH) rst met him at the Ocean Waves Conference in Easton in 1961 (Fig. I. 1). Walter immediately agreed to share with us his recollections on the nearly seventy years of his path-breaking contributions in a sheer amazing range of topics, from ocean waves, internal waves, ocean currents, tides, tsunamis, sea level, microseisms and the rotation of the earth to ocean acoustic tomography. With "you guys" Markus was referring to HvS and the various partners HvS had 1 invited to join him in conducting a series of interviews of retired colleagues.

Data assimilation methods were largely developed for operational weather forecasting, but in recent years have been applied to an increasing range of earth science disciplines. This book will set out the theoretical basis of data assimilation with contributions by top international experts in the field. Various aspects of data assimilation are discussed including: theory; observations; models; numerical weather prediction; evaluation of observations and models; assessment of future satellite missions; application to components of the Earth System. References are made to recent developments in data assimilation theory (e.g. Ensemble Kalman filter), and to novel applications of the data assimilation method (e.g. ionosphere, Mars data assimilation).

This is a book on the practical side of tropical meteorology which in its 3 Parts covered in 12 chapters reviews several current theories and ideas on tropical circulations and monsoons, offering new definitions and ideas to facilitate a systematic development of the subject. The book emphasizes the need for a system's approach to tropical circulations in general and monsoons in particular to facilitate orderly and systematic development of the topic.

This book is dedicated to the study of structure and transport of deep and bottom waters above and through underwater channels of the Atlantic Ocean. The study is based on recent observations, analysis of historical data, and literature reviews. This approach allows us to understand how water transport and water mass prop- ties have changed over the last years and decades. The focus of our study is on the propagation of bottom waters in the Atlantic Ocean based on new field data at key points. At the end of the 1920s, the first integral study of water masses and bottom topography of the Central and South Atlantic was carried out from the German - search vessel Meteor. This German Atlantic Expedition was one of the first cruises equipped with the newly developed echo sounder (fathometer): an obligatory p- requisite for the investigation of bottom morphology in the deep sea on an - erational base. The results of the expedition were published by Wust, Defant, and colleagues in the multivolume METEOR publication series starting with the cruise report by the ship's commander (Spiess 1928, 1932). Historically, this series of p- lications, intermittently interrupted by World War II, was the basis for many years of research into the development of modern concepts about Atlantic water masses and their circulation schemes.

To all those sailors / Who dreamed before us / Of another way to sail the oceans. The dedication of this Volume is meant to recall, and honour, the bold pioneers of ocean exploration, ancient as well as modern. As a marine scientist, dealing with the oceans through the complex tools, ?lters and mechanisms of contemporary research, I have always wondered what it was like, in centuries past, to look at that vast ho- zon with the naked eye, not knowing what was ahead, and yet to sail on. I have tried to imagine what ancient sailors felt, when "the unknown swirls around and engulfs the mind", as a forgotten author simply described the brave, perhaps reckless, act of facing such a hostile, menacing and yet fascinating adventure. Innovation has always been the key element, I think, for their success: another way, a better way, a more effective, safer and worthier way was the proper answer to the challenge. The map of our world has been changed time and again, from the geographical as well as the social, economic and scienti?c points of view, by the new discoveries of those sailors. One of the positive qualities of human beings is without doubt the inborn desire to expand their horizons, to see what lies beyond, to learn and understand.

Oceanic Migration studies the prehistoric peopling of the Pacific. It uses science and mathematics to expand the research base of Pacific prehistory and casts new light on this final human expansion. It explores the fundamental roles of oceanography and of global climate change in determining the paths, sequence, timing and range of Spice Island-based maritime migrations ranging across a quarter of the globe. The book is of interest to Pacific prehistorians, oceanographers and American anthropologists concerned with the diffusionist debate. For oceanographers it presents the new idea of the role of the West Pacific Warm Pool and of three of its four major currents in determining the evolution of voyaging in two oceans. For diffusionists it provides new chronological and technological contexts in which the issue of diffusionism needs to be reconsidered. For prehistorians it creates a paradigmatic shift by establishing a new time depth and mechanism for Polynesian exploration, offers a new view of voyaging and exploration strategies and of economic imperatives and adds a new dimension to the debate on Polynesian origins.

Major natural hazards have sparked growing public concern worldwide. This book provides new information on Typhoon Impact and Crisis Management using satellite remote sensing technology, linking the natural sciences and social sciences in typhoon studies. It examines remote sensing observations of typhoons (hurricanes), typhoon impacts on the environment, typhoon impacts on marine ecosystems, typhoon impacts and global changes, typhoon (hurricane) impacts on economics, and crisis management for typhoon (hurricane) disasters.

With contributions from leading researchers in science and engineering, this book provides a global perspective on submarine mass movements and their consequences.

All studies relied on the most recent technologies, including multi-beam sonar imaging techniques, 3D seismic analysis, slope stability analysis, debris flow, and tsunami modeling.

Dead-Reckoning aided with Doppler velocity measurement has been the most common method for underwater navigation for small vehicles. Unfortunately DR requires frequent position recalibrations and underwater vehicle navigation systems are limited to periodic position update when they surface. Finally standard Global Positioning System (GPS) receivers are unable to provide the rate or precision required when used on a small vessel. To overcome this, a low cost high rate motion measurement system for an Unmanned Surface Vehicle (USV) with underwater and oceanographic purposes is proposed. The proposed onboard system for the USV consists of an Inertial Measurement Unit (IMU) with accelerometers and rate gyros, a GPS receiver, a flux-gate compass, a roll and tilt sensor and an ADCP. Interfacing all the sensors proved rather challenging because of their different characteristics. The proposed data fusion technique integrates the sensors and develops an embeddable software package, using real time data fusion methods, for a USV to aid in navigation and control as well as controlling an onboard Acoustic Doppler Current Profiler (ADCP). While ADCPs non-intrusively measure water flow, the vessel motion needs to be removed to analyze the data and the system developed provides the motion measurements and processing to accomplish this task.

Sidescan sonar is proving to be the preeminent technique for researchers and professionals seeking knowledge about the structure and behavior of the seafloor, but its data is often difficult to interpret due to the physics of acoustic remote sensing, and to the varied geological processes at play. This book covers the fundamentals of sidescan sonar, incorporates new understanding of marine structures, and explains how to interpret sidescan sonar imagery and bathymetry.

As the world grieves over the catastrophic loss of humanity from the 26 December 2004 tsunami, we must resolve to learn from nature's lessons. This issue provides a framework and a set of tools to develop communities that are resilient to tsunami. This collection of papers represents a starting point on our new journey toward a safer world. The history of tsunami hazard mitigation tracks well with the history of destructive tsunamis in the United States. Following the 1946 Alaska g- erated tsunami that killed 173 people in Hawaii, the Paci?c Tsunami Warning Center was established in Hawaii by a predecessor agency to the National Oceanic and Atmospheric Administration (NOAA). Following the 1960 Chilean tsunami that killed 1,000 people in Chile, 61 in Hawaii, and 199 in Japan, the United States formed the Joint Tsunami Research E?ort (JTRE) and sta?ed the International Tsunami Information Center (ITIC) in Hawaii. JTRE was formed to conduct research on tsunamis while ITIC, sponsored by the United Nations, was formed to coordinate tsunami warning e?orts of the Paci?c Countries. Many research and mitigation e?orts were focused on the distant tsunami problem. Following the 1964 Alaskan t- nami that killed 117 in Alaska, 11 in California, and 4 in Oregon, the U. S. was confronted with the local tsunami problem. In response, the U. S. established the Alaska Tsunami Warning Center in Palmer, Alaska. In 1992, a Ms 7.

This book presents new research on the mathematical description of tsunamis and hurricanes. The description includes dissipative terms and does not contain singularities or two valued functions. The book uses the equivalence principle of solutions of nonlinear large gas dynamic waves and of solutions of water wave equations. An extension of the continuity equation by a source term due to evaporation rates of salt seawater help to understand hurricanes. Detailed formula, tables, and results of the calculations are given.
