This site-wide search returns results for all documents, events, metadata, and stories in Tethys, prioritizing the best matches. Partial word matches are returned (e.g. "environment" finds "environmental"), but every entered term must be found. If you don't find any results, try reducing the number of words entered or removing special characters. Filters to the right can help narrow your search. Tethys now features an integrated search with other marine renewable energy databases in PRIMRE - click the buttons below "Showing Results for" to search other integrated databases.

Freeman et al.
With only a few wave and tidal devices in the water and no long-term post-installation datasets available, there continue to be uncertainties around risks to marine animals and habitats from the deployment and operation of marine renewable energy (MRE) systems. Based on these uncertainties and lack of familiarity with MRE devices, regulators and stakeholders continue to perceive a wide array…

The pace of development for wave and tidal energy projects worldwide continues to be hindered by uncertainty surrounding potential environmental effects of the devices and the balance of system. To respond to this uncertainty the Ocean Energy Systems (OES) international agreement developed a collaborative initiative (Annex IV). Over an initial three-year period (2010-2012) Annex IV collected…

Tidal hydrokinetic energy has the potential to provide clean, reliable power, and emerging turbine designs are making production of electricity from ocean energy technologically and economically feasible. Tidal energy projects could be a viable renewable energy source, displacing fossil fuel-based energy resources, providing benefits to the marine environment through the mitigation of carbon…

The pace of development for marine energy projects worldwide continues to be hindered by uncertainty surrounding potential environmental effects of wave and tidal devices and the balance of system. In response to this continued uncertainty, member nations of the Ocean Energy Systems (OES) developed a collaborative project – Annex IV – to increase collection and sharing of knowledge, research…

Copping et al.
The potential risk to marine mammals colliding with turbines is one of the primary environmental concerns slowing tidal energy development in the US and Europe. Few field observations of interactions between marine animals and tidal turbines have been reported [1], necessitating supplemental risk analyses and modeling to help fill the gap. This study provides a surrogate measure of the…

Copping et al.
Commercial development of tidal stream energy is hampered by technical and financial challenges, and impeded by uncertainty about potential environmental effects that drive environmental risk assessments and permitting (consenting) processes. The effect of greatest concern for operational tidal stream energy devices is the potential for marine animals to collide with turbine blades, resulting…

Copping et al.
Many marine mammal populations worldwide are in decline due to stresses from climate change and interactions with anthropogenic activities such as fishing, coastal construction petroleum extraction, and commercial shipping. The advent of the marine renewable energy industry has raised questions, particularly for tidal turbines. However, it is technically very difficult to observe close…

Copping et al.
Concerns about the potential effects of tidal turbines and wave energy devices on the marine environment continue to slow siting and consenting/permitting (hereafter “consenting”) of single devices and arrays worldwide. While research studies and early results from post-installation monitoring over the past decade have informed interactions between marine renewable energy (MRE) devices, marine…

The Marine Animal Alert System (MAAS) was developed by the Pacific Northwest National Laboratory as an element of compliance monitoring to support deployment of marine hydrokinetic energy devices. An initial focus is prototype tidal turbines to be deployed in Puget Sound in Washington State. The MAAS will help manage the risk of injury or mortality to marine animals from blade strike or…

Copping et al.
The pressure to develop new and renewable forms of energy to combat climate change, ocean acidification, and energy security has encouraged exploration of sources of power generation from the ocean. One of the major challenges to deploying these devices is discerning the likely effects those devices and associated systems will have on the marine environment. Determining the effects each device…

Copping et al.
The development of tidal energy technologies has progressed to where devices can be deployed, operated, maintained, and recovered with some level of assurance that they will and produce adequate levels of power. Equally important to further the tidal energy industry is the ability to site and gain regulatory permission to deploy and operate these devices. This paper sets out a framework for…

Many fish species are threatened worldwide by overfishing, contamination, coastal development, climate change, and other anthropogenic activities. Marine renewable energy (MRE) is under development as a sustainable alternative to carbon-based energy sources. Regulators and stakeholders worry that MRE devices will add another threat to fish populations already under pressure. This paper reviews…

The blue economy is a dynamic and rapidly growing movement that captures the interplay between economic, social, and ecological sustainability of the ocean and encompasses numerous maritime sectors and activities (e.g., commerce and trade; living resources; renewable energy; minerals, materials, and freshwater; and ocean health and data). The demand for ocean data to inform scientific, risk…

The “Blue Economy” is a rapidly growing movement based on the economic, social, and ecological sustainability of the ocean and encompasses various maritime activities, including ocean observations. The demand for ocean data to inform scientific, risk reduction, and national security needs relies upon future deployments of observing systems and over coming constraints, such as power. In…

There is global interest in marine renewable energy from underwater tidal turbines. Due to overlap in animal habitat with locations for tidal turbines, the potential for collisions has led to concern around strike risk. Using data from tagged harbor seals collected before construction and after operation of the SeaGen tidal turbine in Northern Ireland, this study quantifies risks of an…

Global expansion of marine renewable energy (MRE) technologies is needed to help address the effects of climate change [1], to ensure a sustainable transition from carbon-based energy sources, and to meet energy security needs using locally generated electricity. Although the amount of potentially harvestable tidal stream and wave energy from nearshore regions around the world is sufficient to…

The purpose of this project is to better understand the acoustic effects of tidal energy devices through evaluation of the baseline environment (by prototyping several types of bottom-mounted and shore-based instrumentation), evaluating the implications of turbine noise at the site of a proposed pilot project in the context of existing ambient noise, using information from baseline monitoring…

The overarching goal of this West Coast Environmental Protocols Framework is to describe a clear, consistent process for regulators and industry to follow when designing environmental baseline and post-installation monitoring studies for proposed wave, tidal and offshore wind projects along the U.S West Coast, thus reducing time and uncertainty associated with project development. The…
