Metadata: 2005, CMACS & Cranfield University, COWRIE Research, Electromagnetic Fields (EMF) Review
Abstract:
The reviewed series of studies were primarily conducted in the UK between 2002 and July 2005 to evaluate the potential environmental impacts of electromagnetic fields (EMFs) from offshore wind farm subsea power cables on electrically and magnetically sensitive marine species, especially elasmobranchs. 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.

| Internal code | Internally assigned metadata identifier | 19396 |
| Title | The title is used to provide a brief and precise description of the dataset such as 'Date', 'Originating organisation/programme', 'Location' and 'Type of survey'. All acronyms and abbreviations should be reproduced in full. | 2005, CMACS & Cranfield University, COWRIE Research, Electromagnetic Fields (EMF) Review |
| Alternative title | The purpose of alternative title is to record any additional names by which the dataset may be known. | The potential effects of electromagnetic fields generated by sub-sea power cables associated with offshore wind farm developments on electrically and magnetically sensitive marine organisms – a review. |
| File Identifier | The File Identifier is a code, preferably a GUID, that is globally unique and remains with the same metadata record even if the record is edited or transferred between portals or tools. | bdd66347-d269-4c65-b9ff-0d8fa9962cc4 |
| Resource Identifier | This is the code assigned by the data owner. | TCE-253 |
| Resource type | The resource type will likely be a dataset but could also be a series (collection of datasets with a common specification) or a service. | series |
| Start date | This describes the date the resource starts. This may only be the year if month and day are not known | 2005-07-01 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2005-07-01 |
| Frequency of updates | This describes the frequency with which the resource is modified or updated i.e. a monitoring programme that samples once per year has a frequency that is described as 'annually'. | notPlanned |

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | Throughout the course of the project there was some confusion about the term electromagnetic field and its present acronym, EMF, which has lead to inconsistencies and mistakes in documentation and discussion. 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. |
