Metadata: 2003, National Wind Power Offshore, North Hoyle, Baseline Monitoring
Abstract:
The North Hoyle Offshore Wind Farm environmental monitoring series, led primarily by National Wind Power Ltd, NWP Offshore Ltd, and the Countryside Council for Wales (CCW), aimed to establish environmental baselines and assess the potential impacts of the wind farm prior to and during its early operation. The main conclusions indicate that baseline conditions were well-characterised, with no significant deviations detected in benthic, fisheries, or marine mammal communities, nor any immediate issues reported by fishermen or stakeholders. Baseline studies determined that the wind farm area is outside current boundaries of potential marine Special Protection Areas (SPAs), though future SPA delineation for red-throated divers remains uncertain. The monitoring also provided foundational data for ornithological populations, noting the need for methodological improvements in bird flight height and movement detection, and highlighted that benthic and aerial survey methods require further refinement for higher precision. Key recommendations include ongoing, targeted monitoring—especially for bird and fish populations, EMF, noise, and vibration—refinement of survey techniques, continued stakeholder engagement, and the use of improved technology to ensure comprehensive long-term evaluation of potential and emerging environmental impacts.

| Other details | ||
| Internal code | Internally assigned metadata identifier | 29856 |
| 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. | 2003, National Wind Power Offshore, North Hoyle, Baseline Monitoring |
| Alternative title | The purpose of alternative title is to record any additional names by which the dataset may be known. | Baseline Monitoring |
| 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. | 649ffb61-7fae-48c4-8f7e-379a85a237cc |
| Resource Identifier | This is the code assigned by the data owner. | TCE-1685 |
| 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 | 2003-01-01 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2003-06-26 |
| 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. | The series describes the baseline monitoring undertaken to comply with the conditions of the Food and Environmental Protection Act (FEPA) 1985: Part II (as amended), licence reference 31579/02/0 (as amended), issued to NWP Offshore Ltd. for the North Hoyle Offshore Wind Farm. Subtidal (benthic) sediments were sampled from 17 agreed locations in and around the development site using a Day Grab. Suspended sediments are being monitored to determine any near and far field effects of windfarm construction and post-construction conditions. Benthic organisms: Three replicate samples were obtained from the 17 locations used for the subtidal sediment sampling by the same methods. Consultation with fisherman and appropriate bodies has been undertaken and is ongoing through the Fisheries Liaison Officer....abundance or change in distribution of their catches Marine mammals: site-specific counts being carried out in combination with ornithological surveys. Ornithology: Surveys were conducted for 5 objectives for ornithological monitoring. |
