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.

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…

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…
- Conference Paper:
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…
- Report:
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…

… and; changes in circulation and sediment transport from MRE device operation (Kropp 2013; Copping et al. 2016; Copping and Grear 2018). Uncertainty remains about these potential interactions between MRE …
- Presentation:
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…
- Journal Article:
Yang et al.
This paper presents a numerical modeling study for simulating in-stream tidal energy extraction and assessing its effects on the hydrodynamics and transport processes in a tidal channel and bay system connecting to coastal ocean. A marine and hydrokinetic (MHK) module was implemented in a three-dimensional (3-D) coastal ocean model using the momentum sink approach. The MHK model was validated…
- Journal Article:
Wang et al.
To assess the effects of tidal energy extraction on water quality in a simplified estuarine system, which consists of a tidal bay connected to the coastal ocean through a narrow channel where energy is extracted using in-stream tidal turbines, a three-dimensional coastal ocean model with built-in tidal turbine and water quality modules was applied. The effects of tidal energy extraction on…

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…
- Journal Article:
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…
- Conference Paper:
Copping et al.
Potential environmental effects from tidal and wave devices are of concern to regulators, advisors, and other stakeholders in many nations. Monitoring results from early deployments and the first commercial arrays, coupled with targeted research studies, are providing a growing base of knowledge of how components of tidal turbines and wave energy …

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…
- Report:
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…
- Journal Article:
Whiting et al.
The placement and operation of marine energy deployments in the ocean have the potential to change flow patterns, decrease wave heights, and/or remove energy from the oceanographic system. Changes in oceanographic systems resulting from harvesting marine energy, particularly tidal and wave energy, may be of concern. These changes include alterations in nearfield and farfield physical processes…

Yang et al.
Understanding and providing proactive information on the potential for tidal energy projects to cause changes to the physical system and to key water quality constituents in tidal waters is a necessary and cost-effective means to avoid costly regulatory involvement and late stage surprises in the permitting process. This paper presents a modeling study for evaluating the tidal energy…
- Conference Paper:
Copping et al.
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.
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…

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…

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…
