The OES-Environmental 2020 State of the Science Report: Environmental Effects of Marine Renewable Energy Development Around the World builds on and serves as an update and a complement to the 2013 Final Report for Phase 1 of OES-Environmental and the 2016 State of the Science Report. Its content reflects the most current and pertinent published information about interactions of marine renewable energy (MRE) devices and associated infrastructure with the animals and habitats that make up the marine environment. It has been developed and reviewed by over 60 international experts and scientists from around the world as part of an ongoing effort supported by the OES collaboration that operates within the International Technology Cooperation Framework of the International Energy Agency (IEA).
Some of the chapters in the 2020 State of the Science Report contained more information and technical details than could be accommodated in the main report. These materials appear as supplementary materials, which are linked within the 2020 State of the Science Report itself and available for download on the 2020 State of the Science Report Supplementary Materials page.
Chapter 10: Environmental Monitoring Technologies and Techniques for Detecting Interactions of Marine Animals with Turbines describes the research on existing environmental monitoring technologies and lessons learned from monitoring programs for turbines. The greatest potential risk from turbine operation continues to be perceived by regulators and other stakeholders to be that of marine animals colliding with turbine blades. These potential interactions are the most difficult to observe using common oceanographic instruments and must be undertaken in parts of the ocean where fast moving water and high waves make studies challenging.
The Chapter 10 Supplementary Material provides information on instrument classes used for monitoring marine renewable energy devices such as passive acoustics, active acoustics, and video cameras. It also describes the applications and challenges of video cameras, and provides a technical glossary related to monitoring terminologies.
