An Assessment of The Capabilities of The In-faunal Quality Index (IQI) To Detect Benthic Ecological Change Within Offshore Windfarm Developments / SAUL MOORE

Swansea University Author: SAUL MOORE

Abstract

Many governments are turning to renewable sources of energy to tackle the current climate emergency and ensure current and future energy demands are met. Offshore wind energy is one of the fastest growing areas of the energy sector, however with increasing areas of the ocean floor being used for win...
