Introduction
Marine renewable energy (MRE), such as wave, tidal stream, salinity gradient, and ocean thermal energy, is under development in many parts of the world. However, studies examining the environmental effects of MRE have primarily focused on deployments in temperate and Northern Hemisphere countries.
OES-Environmental is conducting this survey to collect any existing information relevant to the potential environmental effects of MRE in tropical and subtropical countries. We are specifically looking for information on any active or planned MRE projects in these regions; any research, monitoring, or modeling efforts; and any literature or other resources that may be relevant. We are also looking for specific contacts and/or organizations with relevant experience and interest in these areas.

The results of the survey used to progress the recommendations from Chapter 10: Environmental Effects of Marine Renewable Energy in Tropical and Subtropical Ecosystems of the 2024 State of the Science Report.
Based on existing research studies and monitoring efforts, key areas of uncertainty and subsequently research underway in relation to the potential environmental effects of MRE include:
- Collision Risk for Animals Around Operating Tidal Turbines
- Risk to Marine Animals from Underwater Noise
- Risk to Marine Animals from Electromagnetic Fields
- Changes in Benthic & Pelagic Habitats
- Changes in Oceanographic Systems
- Entanglement Risk
- Displacement Risk
