Energy and material are continually exchanged at the interfaces between water and air, ice, rocks, and sediments. In addition to the physical and chemical processes, biological processes play a significant role. Vast areas of the ocean remain unexplored. Investigation of the surface ocean is carried out by satellites. All other observations and measurements have to be carried out in-situ using research vessels and spe- cial instruments. Ocean observation requires the use of special technologies such as remotely operated vehicles (ROVs), autonomous underwater vehicles (AUVs), towed camera systems etc. Seismic methods provide the foundation for mapping the bottom topography and sedimentary structures. We cordially welcome you to the international OCEANS ’09 conference and exhibition, to the world’s leading conference and exhibition in ocean science, engineering, technology and management. OCEANS conferences have become one of the largest professional meetings and expositions devoted to ocean sciences, technology, policy, engineering and education. -

An Update on Large Scale Wave Energy Conversion
AN UPDATE ON LARGE SCALE WAVE ENERGY CONVERSION Rik van Hemmen, Fellow and Michael Raftery Member Martin Ottaway van Hemmen & Dolan, Inc. [email protected] [email protected] SNAME – SMC 2019 Technical Paper – Peer Reviewed Abstract Submission SNAME FACE: Engineers/Designers Topic: Design and Engineering, Sustainable Energy It is time for Wave Energy Conversion (WEC) to be part of the sustainable energy toolbox at a utility level. Solar and wind renewable power systems are now sustainable technologies which are economically competitive with existing fossil fuel and nuclear options. Even though there have been WEC development efforts as long as there have been industrial solar and wind efforts, WEC systems simply have never made it out of the experimental starting blocks. This paper examines prior efforts and examines why they have failed at a utility level and describes the design and engineering of emerging technologies that could make large scale wave energy conversion competitive with present state of the art large scale wind and solar projects. The SurfWEC concept is introduced as a game changing approach to achieve much lower Levelized Cost of Electricity (LCOE) rates than are achievable with existing WEC approaches by enabling significant increases in kinetic energy input to various WEC designs.

Assessment of the Effects of Noise and Vibration from Offshore Wind Farms on Marine Wildlife
ASSESSMENT OF THE EFFECTS OF NOISE AND VIBRATION FROM OFFSHORE WIND FARMS ON MARINE WILDLIFE ETSU W/13/00566/REP DTI/Pub URN 01/1341 Contractor University of Liverpool, Centre for Marine and Coastal Studies Environmental Research and Consultancy Prepared by G Vella, I Rushforth, E Mason, A Hough, R England, P Styles, T Holt, P Thorne The work described in this report was carried out under contract as part of the DTI Sustainable Energy Programmes. The views and judgements expressed in this report are those of the contractor and do not necessarily reflect those of the DTI. First published 2001 i © Crown copyright 2001 EXECUTIVE SUMMARY Main objectives of the report Energy Technology Support Unit (ETSU), on behalf of the Department of Trade and Industry (DTI) commissioned the Centre for Marine and Coastal Studies (CMACS) in October 2000, to assess the effect of noise and vibration from offshore wind farms on marine wildlife. The key aims being to review relevant studies, reports and other available information, identify any gaps and uncertainties in the current data and make recommendations, with outline methodologies, to address these gaps. Introduction The UK has 40% of Europe ’s total potential wind resource, with mean annual offshore wind speeds, at a reference of 50m above sea level, of between 7m/s and 9m/s. Research undertaken by the British Wind Energy Association suggests that a ‘very good ’ site for development would have a mean annual wind speed of 8.5m/s. The total practicable long-term energy yield for the UK, taking limiting factors into account, would be approximately 100 TWh/year (DTI, 1999). -

Contents 1. An Acoustical View of Oceanography 2. The History of Research on Ocean Acoustics 3. Measurement of Speed of Sound 3.1. The Sound Speed Profile 3.2. Propagation Theory 3.3. Applications of Underwater Acoustics 4. Other Applications Bibliography Biographical Sketch Summary Underwater acoustics is an important science with significant practical application, especially for the application in ocean. Electro-magnetic waves, which are strongly absorbed by water, have their limits in propagation range in water. Therefore, acoustic waves play an important role on the navigation, underwater communication, underwater detection, and investigation in ocean research. The ocean is an inhomogeneous medium with various sound velocity profiles that vary with depth because of changes in temperature, hydrostatic pressure and salinity. Due to these sound velocity profiles, acoustic wave propagation in ocean results in several interesting phenomena such as surface duct, shadow zone, SOFAR (deep sea) channel, etc. These phenomena all have practical application in underwater communication and detection. Theoretical models and their numerical algorithms for wave propagation are developedUNESCO to describe the complicated ocean– phenomenaEOLSS of wave propagation. Some of these models, such as: acoustic ray model, normal mode model, PE (parabolic wave equation) models are described in this section. SAMPLE CHAPTERS Sonar equations comprise a group of parameters, which considers the phenomena and effects of the underwater sound. -
