Metadata: 2019, Ocean Ecology, Burbo Bank Extension, Benthic Ecology Survey
Abstract:
This report presents the findings of the second Burbo Bank Extension (BBW02) post-construction benthic survey undertaken by Ocean Ecology Limited (OEL) on behalf of Ørsted. The benthic survey was undertaken between 8th and 9th September 2019 aboard the vessel Seren Las. During this survey, a total of 30 macrobenthic and 54 Particle Size Distribution (PSD) samples were collected within the wind farm array, near-field and adjacent reference areas. In addition, 102 seabed images combined with associated video were collected at eight drop-down video sampling stations and along four camera transects within the Export Cable Route (ECR) corridor. A full description of survey operations is provided in the benthic survey report (Appendix 1). This report aims to provide an assessment of the benthic habitats and associated infaunal assemblages within and adjacent to the areas of potential impact resulting from the construction and operation of the BBW02 offshore wind farm. It also provides a comparison with previous data collected during the 2015 pre-construction and 2017 post-construction surveys to determine the magnitude of impacts predicted in the Environmental Statement (ES).

| Internal code | Internally assigned metadata identifier | 19198 |
| 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. | 2019, Ocean Ecology, Burbo Bank Extension, Benthic Ecology Survey |
| Alternative title | The purpose of alternative title is to record any additional names by which the dataset may be known. | Benthic Ecology Survey |
| 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. | 6d3e228d-7c86-4159-a163-89356ae97829 |
| Resource Identifier | This is the code assigned by the data owner. | TCE-3484 |
| 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 | 2019-09-07 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2019-09-08 |

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | Grab and drop-down camera sampling was undertaken during favourable weather conditions between 8 and 9th September 2019 aboard the vessel, Seren Las operating out of Liverpool. All targeted grab, drop-down camera stations and transects were visited with 30 macrobenthic samples, 54 Particle Size Distribution (PSD) sub-samples and over 100 high-definition still images and associated video were successfully collected across the survey area. All corresponding macrobenthic, PSD and seabed imagery analysis was undertaken at OELs NE Atlantic Marine Biological Quality Control (NMBAQC) scheme participating laboratory during September to December 2019. Univariate and multivariate statistical analyses were carried out on all data collected using PRIMER v7 and R v 1.2.1335 with each sampling station assigned to a treatment group to allow for a temporal comparison between pre- and post-construction periods The vessel was equipped with a Vector V104â?¢ GNSS compass GPS system that provided an accurate offset position of the sampling equipment when deployed from the stern. This provided a GPS feed to a dedicated survey navigation computer, which was later used to produce an overlay on the seabed video footage. Seabed imagery was collected using OELs ROVTech subsea camera system providing 1080p High Definition (HD) video and 20 Megapixel (MP) still images, mounted in a hydrostatic freshwater housing and bespoke mounting frame. Two laser pointers separated by 10 cm were mounted in the frame and projected into the field of view for a measure of scale. Grab sampling was undertaken using OELs 0.1 m2 Day grab. |
