The study of marine ecological environment and benthic biodiversity around the perimeter of offshore wind farms, which facilitates the understanding of possible changes in marine environment and ecology caused by the construction of offshore wind farms in Taiwan and to serve as a reference for future policy evaluation of sustainable development of offshore wind power.
The impact of offshore wind farm construction on marine ecosystems, including ecology, benthic composition and bait sources, which are important issues that need to be urgently investigated and studied.
This project is an extension of the 2020 project to investigate the ecological environment and benthic biodiversity in the waters surrounding offshore wind farms, and to collect and compile relevant research data in the waters surrounding offshore wind farms in both domestic and international locations, as well as to conduct field surveys and analyses. The results can be used by government agencies, domestic and foreign research institutions and organizations to understand the environmental and ecological changes that may be caused by the construction of offshore wind farms in Taiwan and will serve as a reference for future policy evaluation of the sustainable development of offshore wind power.

In accordance with the "Salute to the Sea" policy promoted by the Executive Yuan, we are conducting information collection and resource surveys on marine organisms in the northern, southern Taiwan, as well as the seas around Penghu, including fish, invertebrates (Cnidaria, Mollusca, Arthropoda and Echinodermata), macroalgae. We aim to build a directory of marine species, biological and ecological pictures, species descriptions and information on toxic or dominant species and to measure the underwater environmental indicators of intertidal and sub-tidal zones in various areas in order to grasp the information of marine life species and dive sites in Taiwan’s seas, and to provide information for the future website development of an exhibition platform, in order to improve the marine knowledge and marine literacy of the nation.

In this project, the towed hydrophone passive acoustic monitoring system and the bottom passive acoustic monitoring system are used to establish the soundscape data and the underwater noise transmission study in the offshore wind farm area.
By measuring the underwater soundscape data, the marine environment can be evaluated and the characteristics of spatial and temporal distribution can be analyzed. By continuing to track and establish long-term data and applying the completed analysis techniques to other marine zones, we can gradually improve the grasp of acoustic data of each offshore wind power construction area, so that we can provide future reference for the relevant units to formulate the impact of underwater noise transmission and offshore wind power development.
