It involved range of methodologies including literature reviews, technical and cost analyses, environmental monitoring, empirical laboratory studies, consultation with industry and experts, technical and environmental data requests to developers, and conference participation. The series found that while some marine species can detect weak EMFs and may alter their behaviour in proximity to anthropogenic sources, there is currently no conclusive evidence of significant ecological harm attributable to EMFs from offshore wind farms, especially with mitigation strategies such as cable burial and shielding. However, substantial knowledge gaps remain regarding the sensitivity, ecological consequences, and cumulative impacts on key species, and inconsistencies were noted in environmental statements and monitoring protocols.

Here we suggest a set of unambiguous labels based on standard electrical nomenclature relating to the different components of an electromagnetic field (EMF) field for clarity in any future publication or communication. The results of the COWRIE Phase 1 work demonstrated that the EMF emitted by industry standard AC offshore cables had a magnetic (B) field component and an induced electric (iE) field component. These EMF components were assessed as being within the range of detection by EM-sensitive aquatic species but whether any potential impact would result remained unknown. It was noted however that a number of monitoring studies for existing wind farms were underway and that these may assist in the determination of potential impact in the future. In addition, during 2003 further consents for development were issued for three strategic areas of the English/Welsh/Scottish coastal zone. COWRIE Ltd.
