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.

The 2020 State of the Science Report was released on 8 June 2020 by Ocean Energy Systems (OES)-Environmental, supported by the International Energy Agency, and dedicated to examining the environmental effects of marine renewable energy (MRE)…
- Tethys Story:
Global renewable energy usage is on a steep upward trajectory, much of which is being driven by wind and solar. However, because of the variability of these sources, renewables are best implemented across as a diverse combination of resources and geography as possible. Therefore, utilizing a new renewable resource that is completely uncorrelated with wind and solar is clearly of benefit. Wave…

The Fundy Ocean Research Center for Energy (FORCE) is Canada’s leading center for research and demonstration of in-stream tidal energy technologies. Located in the Bay of Fundy in the Atlantic province of Nova Scotia, FORCE has been collecting environmental and site characterization data for almost ten years. Based on this experience, FORCE has a role to play in supporting informed, evidence-…

A small nonprofit based in Portland, Ore. is helping to place the Pacific Region of the United States – comprised of California, Oregon, Washington, Alaska, and Hawaii – on the map as a vibrant destination for ocean renewable energy research and development. Available offshore wind, wave, and tidal resources offer significant opportunity for states in the Pacific Region to meet their…

The number of fatal bird collisions at wind turbines is rarely studied in relation to the number of birds observed crossing an area. The reason might be that the acquisition of such data is time consuming, costly, and not trivial. The analysis and interpretation of radar data is especially difficult. Furthermore, there are a variety of radar systems and not all systems are technically suitable…

Jim Strittholt, Conservation Biology Institute (US) In order to effectively combat climate change, rapid transition to renewable energy is essential and new economic opportunities are rapidly emerging. The recent progress towards renewable energy is encouraging, but care must be taken to avoid unintended negative consequences on wildlife and existing human uses whether these…

As the marine renewable energy (MRE) industry advances and devices are deployed, there is a need to understand potential environmental effect of introducing structures to marine waters and potentially attracting marine organisms. These structures may act as artificial reefs, underwater human-made structures that function similar to a natural reef, and can include oil and gas platforms, sunken…

At the University of Rhode Island in the United States, a study of electromagnetic field (EMF) impacts on elasmobranchs and lobsters is currently being conducted. The contract is led by the Bureau of Ocean Energy Management and the study aims to assess impacts of direct current (DC) cables on marine organisms. The study was prompted by the potential for the “Atlantic Wind Connection” venture,…

The Province of Nova Scotia has set an ambitious renewable energy production target of 40% by 2020. One of the mechanisms to achieve this goal, initiated by the Province, was the creation of the Fundy Ocean Research Centre for Energy (FORCE) tidal turbine test facility in the Minas Passage, Bay of Fundy. The first of two commercial-scale tidal turbines (16…

Adaptive management (AM) is a learning-based management approach that is used to reduce scientific uncertainty. AM has been identified as a tool to advance the wind energy industry, although its application in practice has been limited. AM has primarily been actively implemented in the United States, while other nations have applied some of the principles of AM. Many wind energy projects use…

One of the key features of renewable energy generation is its benefit to the environment through developing low carbon power sources, so it’s important to develop new types of renewable energy in environmentally responsible ways. Collecting and analyzing environmental data necessary for marine energy projects is difficult – the areas of interest are highly energetic, with (typically) little…

Wind energy developers face challenges to gain public acceptance and necessary permits because of potential impacts on wildlife, especially birds and bats. As a result, developers may be required to monitor projects for the presence and abundance of both diurnal and nocturnal species, collect data on bird or bat collisions with turbines, and implement mitigation strategies that reduce…

Annex IV and ORJIP-Ocean Energy has signed an agreement that will enhance collaboration and data sharing to understand and reduce uncertainty about potential environmental effects of MRE development. Both organizations address issues that are challenging to the siting and permitting/consenting of wave and tidal projects. Annex IV and ORJIP Ocean Energy plan to jointly develop and share…

As tidal energy development ramps up in Europe and North America, questions have been raised about the potential for turbine blades to strike marine mammals, fish, and other marine organisms. Less attention has been paid to potential threats to smaller planktonic organisms such as the larvae of fish, lobster, and the zooplankton that spend their lives floating in moving ocean water. A small…
