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 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 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 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…

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…

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 …
- 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…

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…

Woodruff et al.
Energy generated by the world’s oceans and rivers offers the potential to make substantial contributions to the domestic and global renewable energy supply. However, the marine and hydrokinetic (MHK) energy industry faces challenges related to siting, permitting, construction, and operation of pilot and commercial-scale facilities. One of the challenges is to understand the potential effects…
- Journal Article:
Copping et al.
Marine renewable energy (MRE) is under development in many coastal nations, adding to the portfolio of low carbon energy sources that power national electricity grids as well as off-grid uses in isolated areas and at sea. Progress in establishing the MRE industry, largely wave and tidal energy, has been slowed in part due to uncertainty about environmental risks of these devices, including…
- Conference Paper:
Copping et al.
Commercial marine renewable energy (MRE) developments can take extended periods of time to progress, in part due to complicated permitting processes that require expensive data collection and data review. Much of this delay is associated with uncertainty around potential effects of MRE on marine animals and habitats, leading regulators and stakeholders to believe that significant risks may…

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…

Ward et al.
To address the complexity of environmental issues associated with MHK energy, PNNL has received support from the Department of Energy Office of Energy Efficiency and Renewable Energy Waterpower Program to develop research and development that draws on the knowledge of the industry, regulators, and stakeholders. Initial research has focused on 1) the development of a knowledge management…

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…

Copping et al.
Marine renewable energy (MRE) is increasingly of interest to coastal nations as a source of renewable energy that can support climate change mitigation goals as well as provide secure locally-produced energy for coastal and island communities. MRE extracts power from tidal streams, waves, ocean currents, run of rivers, and gradients in the ocean, with specialized devices developed and tested…

Chapter 3 encompasses the progress made on understanding the major stressor-receptor interactions that help delineate potential risks from MRE development. Each interaction has been the focus of multiple research and monitoring studies since the 2020 State of the Science report. COLLISION RISK FOR MARINE…

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…
