At present and over the next few years, large-scale windfarms are being installed far off the coast of Germany in the North and Baltic Sea, making a major contribution to electricity generation from renewable energy sources. One of the German government’s aims is to ensure the environmentally sound and sustainable development of offshore wind energy. Germany’s first offshore test site, alpha ventus, was therefore accompanied from the construction phase to the first years of operation by an intensive environmental research programme, the StUKplus project, financed by the Federal Ministry for the Environment, Nature Conservation and Nuclear Safety and coordinated by the Federal Maritime and Hydrographic Agency. Marine and ecological aspects have been researched there for more than five years to improve the level of knowledge about the ecological impacts of offshore windfarms. This book provides a broad, richly illustrated overview of applied and new research methods and monitoring techniques. It summarises the key research findings on the impacts on benthic communities, fish, marine mammals and birds, also taking into account underwater sound and sediment measurements. Interpreting the results in the sense of lessons learned, new challenges and perspectives are discussed for future sustainable offshore development in German waters.

Marine mammals face a large array of stressors, including loss of habitat, chemical and noise pollution, and bycatch in fishing, which alone kills hundreds of thousands of marine mammals per year globally. To discern the factors contributing to population trends, scientists must consider the full complement of threats faced by marine mammals. Once populations or ecosystems are found to be at risk of adverse impacts, it is critical to decide which combination of stressors to reduce to bring the population or ecosystem into a more favorable state. Assessing all stressors facing a marine mammal population also provides the environmental context for evaluating whether an additional activity could threaten it. Approaches to Understanding the Cumulative Effects of Stressors on Marine Mammals builds upon previous reports to assess current methodologies used for evaluating cumulative effects and identify new approaches that could improve these assessments. This review focuses on ways to quantify exposure-related changes in the behavior, health, or body condition of individual marine mammals and makes recommendations for future research initiatives.

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.

In September 2012, the Natural Environment Research Council (NERC) announced a consultation process on proposals to merge the British Antarctic Survey and National Oceanography Centre. It argued that there was a strong strategic case for the merger, arising from scientific synergies between the organisations, a drive to maximise the social and economic impact of scientific research output and a need to make the most cost effective use of marine and polar infrastructure. A number of serious concerns have been raised about the prospect of merging the British Antarctic Survey and National Oceanography Centre, and the way in which the consultation has been handled. It's important that these concerns are addressed by NERC before any further action is taken. NERC has not properly consulted on whether a merger is the best way to achieve its objectives and has not provided an adequate evidence base to support its case for a merger, with the absence of projected cost savings being particularly notable. In addition, NERC does not appear to have given adequate consideration to the British Antarctic Survey's geopolitical role when drafting its consultation proposals. Nor has it demonstrated an awareness of UK political commitments on protecting the environment, and polar regions in particular. NERC should consider whether its aims could be achieved by means other than a merger. Future consultations should be carried out with better engagement with scientists and other stakeholders

"TRB Special Report 310: Worker Health and Safety on Offshore Wind Farms examines the hazards and risks to workers on offshore wind farms on the outer continental shelf as compared with the hazards and risks to workers on offshore oil and gas operations. The report explores gaps and overlaps in jurisdictional authority for worker health and safety on offshore wind farms and evaluates the adequacy of--and recommends enhancements to--the existing safety management system (SMS) requirement published in 30 CFR 585.810. The study committee recommends that the U.S. Department of the Interior's Bureau of Ocean Energy Management (BOEM) adopt a full SMS rule for workers on offshore wind farms at a level of detail that includes the baseline elements identified in this report. An enhanced SMS rule should require the use of human factors engineering elements in the design process and should encompass all activities that the lessee and its contractors undertake. In collaboration with other regulatory agencies and industry stakeholders, BOEM should clearly define roles and responsibilities and indicate which standards could apply for all phases of wind farm development, regardless of jurisdiction. Also, with the help of stakeholders, BOEM should support the development of guidelines and recommended practices that could be used as guidance documents or adopted by referen"-

TRB Special Report 305: Structural Integrity of Offshore Wind Turbines: Oversight of Design, Fabrication, and Installation explores the U.S. Department of the Interior's Bureau of Ocean Energy Management, Regulation, and Enforcement (BOEMRE) approach to overseeing the development and safe operation of wind turbines on the outer continental shelf, with a focus on structural safety. The committee that developed the report recommended that in order to facilitate the orderly development of offshore wind energy and support the stable economic development of this nascent industry, the United States needs a set of clear requirements that can accommodate future design development. The report recommends that BOEMRE develop a set of requirements that establish goals and objectives with regard to structural integrity, environmental performance, and energy generation. The committee found that the risks to human life and the environment associated with offshore wind farms are substantially lower than for other industries such as offshore oil and gas, because offshore wind farms are primarily unmanned and contain minimal quantities of hazardous substances. This finding implies that an approach with significantly less regulatory oversight may be taken for offshore wind farms. Under this approach, industry would be responsible for proposing sets of standards, guidelines, and recommended practices that meet the performance requirements established by BOEMRE. The domestic industry can build on standards, guidelines, and practices developed in Europe, where the offshore wind energy is further developed, but will have to fill gaps such as the need to address wave and wind loadings encountered in hurricanes. The report also includes findings and recommendations about the role that certified verification agents (third party evaluators) can play in reviewing packages of standards and project-specific proposals.

For more information on this title, including student exercises, please visit , Energy and Climate Change: Creating a Sustainable Future provides an up-to-date introduction to the subject examining the relationship between energy and our global environment. The book covers the fundamentals of the subject, discussing what energy is, why it is important, as well as the detrimental effect on the environment following our use of energy. Energy is placed at the front of a discussion of geo-systems, living systems, technological development and the global environment, enabling the reader to develop a deeper understanding of magnitudes. Learning is re-enforced, and the relevance of the topic broadened, through the use of several conceptual veins running through the book. One of these is an attempt to demonstrate how systems are related to each other through energy and energy flows. Examples being wind-power, and bio-mass which are really solar power via another route; how the energy used to evaporate sea water must be related to the potential for hydropower; and where a volcano’s energy really comes from. With fermi-like problems and student exercises incorporated throughout every chapter, this text provides the perfect companion to the growing number of students taking an interest in the subject.
