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.

Hutchison and Copping
This report outlines a coordinated action plan aimed at reducing the scientific uncertainty associated with collision risk of marine animals and tidal turbines. This plan includes steps to take toward resolving the challenging issue of decreasing scientific uncertainty, but is unlikely to completely solve the problem. The content of this report was derived from the involvement of experts…

Copping and Grear
Floating offshore wind farms have been proposed in the deep waters off the U.S. west coast and Hawaii to provide renewable energy to coastal populations.Anchoring floating wind platforms to the seabed requires multiple mooring lines that pass through the water column from platforms at the surface to the sea floor. Electrical cables also will be draped in the water column between wind platforms…

Copping and Kramer
With only a few wave and tidal devices in the water and no long-term post-installation data sets available, there continue to be uncertainties around risks to marine animals and habitats from the deployment and operation of marine renewable energy (MRE) systems [1], [2]. Based on these uncertainties and lack of familiarity with MRE devices, regulators and stakeholders continue to perceive a…

Copping and Farr
This research examined the feasibility of developing small-scale OTEC (3-10 MW) in U.S. waters through case studies in four locations (i.e., Hawaii, Puerto Rico, St. Croix, and Guam). In addition to talking to local leaders and experts in OTEC development and processes, we examined the likely environmental effects that will drive permitting (consenting) and licensing processes in the U.S. and…

Hemery et al.
Marine energy devices harness power from attributes of ocean water to form a sustainable energy source. Knowledge gaps remain about whether marine energy systems can affect the environment, adding another threat to animal populations and habitats already under pressure from climate change and anthropogenic activities. To date, potential environmental effects have been studied under the scope…
- Presentation:
Copping et al.
Surface-placed wave energy converters, floating tidal turbines, and floating offshore wind platforms all require anchoring to the seabed with multiple mooring lines and electrical cables passing through the water column, from near the sea surface to the sea floor. Concerns have been raised that large whales may collide with and/or become entangled in lines and cables from renewable energy…

Freeman et al.
This poster presentation covered the uncertainty about effects of marine renewable energy (MRE) and how this continues to slow consenting/permitting processes. Another argument presented was that sharing the considerable body of information on MRE environmental effects can facilitate decision-making and regulatory processes. Ocean Energy Systems (OES)-Environmental, an international initiative…

Commercial interest in developing floating wind energy in the deep waters of the Pacific Outer Continental Shelf has raised questions about whales and other large cetaceans potentially encountering the mooring lines and electrical cables from a floating offshore wind farm. The BOEM Pacific Region asked the Pacific Northwest National Laboratory to create an animated simulation of a humpback…

Copping et al.
The deployment and operation of a floating tidal technology in the United States require assessing environmental conditions and satisfying all environmental permitting requirements. Two locations in the United States are chosen to evaluate the potential for deployment of the Orbital Marine Power Ltd. floating technology: San Juan Islands (Washington) and Western Passage (Maine). This report…

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.
Power generated from marine energy devices, including those that harvest power from the waves and tides, has the potential to help meet the low-carbon energy needs of many coastal nations. However, these devices, and their related mooring lines, anchoring and buoyancy systems, and power export cables are still under development, resulting in a lack of understanding of potential environmental…

Joy et al.
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…

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…

Hasselman et al.
Global expansion of marine renewable energy (MRE) technologies is needed to help address the impacts of climate change, to ensure a sustainable transition from carbon-based energy sources, and to meet national energy security needs using locally-generated electricity. However, the MRE sector has yet to realize its full potential due to the limited scale of device deployments (i.e., single…

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…

Marine renewable energy (MRE) harnesses energy from the ocean and provides a low-carbon sustainable energy source for national grids and remote uses. The international MRE industry is in the early stages of development, focused largely on tidal and riverine turbines, and wave energy converters (WECs), to harness energy from tides, rivers, and waves, respectively. Although MRE supports climate…

Hemery et al.
For marine wave and tidal energy to successfully contribute to global renewable energy goals and climate change mitigation, marine energy projects need to expand beyond small deployments to large-scale arrays. However, with large-scale projects come potential environmental effects not observed at the scales of single devices and small arrays. One of these effects is the risk of displacing…
