Metadata: 2011, IECS, Zone 2 - Firth of Forth, North Sea Offshore Benthic Surveys
Abstract:
The Institute of Estuarine and Coastal Studies (IECS) was commissioned by Seagreen Wind Energy Limited to undertake an offshore benthic survey. This survey work and associated sample analysis was designed to enable characterisation of the benthic and epibenthic ecology of the area, the physical characteristics of the sample sites, and the chemical properties of sediments sampled. In order to provide adequate sampling coverage of the proposed development site Seagreen Wind Energy Ltd., in conjunction with Royal Haskoning, identified 150 benthic sampling sites and 50 video and epibenthic trawl sites within the Phase 1 area, in addition to 3 Met Mast sites across the Phase 1 and 2 areas. All survey work was completed between February and April 2011 and the subsequent sample analysis completed by August 2011.

| Internal code | Internally assigned metadata identifier | 19550 |
| 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. | 2011, IECS, Zone 2 - Firth of Forth, North Sea Offshore Benthic Surveys |
| Alternative title | The purpose of alternative title is to record any additional names by which the dataset may be known. | North Sea Offshore Benthic Surveys |
| 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. | d19218be-db5d-4bc2-ba82-1dd0d87b8681 |
| Resource Identifier | This is the code assigned by the data owner. | CES-399 |
| 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 | 2011-04-01 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2011-06-29 |
| 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. | A total of 150 benthic stations were identified by Seagreen in the Phase 1 area, 19 in the Export Cable Route corridor as well as three Met Mast sites across Phases 1 and 2. A mini Hamon grab was deployed to collect a single replicate sample for infaunal analysis (Plate 1), from which a PSA sample was also taken, as per the specification. A second grab was collected for contaminant analysis. A full survey log was maintained throughout the survey detailing time of sampling, position (DGPS derived), station, water depth, volume of sample, physical characteristics of the sample, digital image number (cross referencing (QA)), presence of Sabellaria spinulosa and any other relevant features. The infaunal samples were processed on a sequential basis utilising a nested sieving technique. Each acceptable sample was removed from the grab, photographed with an internal label, placed into a hopper and sieved onboard through a nest of 5mm and 1mm sieves. A nested sieve approach was used in order to separate large sediment types and reduce damage to invertebrates. The sieved residue was gently back-washed into a sealable container and borax buffered 4% formo-saline solution containing Rose Bengal vital stain added as a fixative. Each sample was labelled clearly on the bucket and the internal label placed in the container, noting the client, survey, date and station number. The PSA and organic carbon samples were stored in separate plastic bags, which were clearly labelled, and frozen onboard the vessel. The samples were kept frozen during transportation back to the IECS laboratory. At the laboratory the samples were stored in the freezer. The IECS methodology followed the protocol given by Rees et al. (1990)1 and (1993)2, Davies et al. (2001)3, Boyd (2002)4 and Proudfoot et al. (2004)5. Samples comprising hard substrata (e.g. broken shell, rocks or gravel) were rejected if a minimum sample volume of 5 litres was not achieved. When samples were within these limits, each sample was photographed (digital image) and subsequently processed. Five attempts were made at each site to collect a valid infaunal sample, however if a sample with a volume less than 4 litres was retained the VideoRay was deployed at the site in order to obtain supporting video footage of the seabed. |
