Metadata: 2008-2009, Ecology Consulting, Kentish Flats, Review of Monitoring of Red Throated Divers
Abstract:
The report in this series presents a review and re-analysis of the diver data collected at the Kentish Flats offshore wind farm in order to evaluate the effect of the construction and the operation of the site on the distribution and numbers of divers in and around the project area. The study evaluates data collected during the preconstruction and post-construction boat surveys (7 years to 2007), including a revised analysis of the spatial distribution of the divers before and after construction of the wind farm to determine whether any displacement has taken place. It also includes an analysis of new data sets from surveys completed during 2008-09. The boat-based surveys conducted during 2001-2007 followed the standard Seabirds at Sea survey methodology (Komdeur et al. 1992). This general method is not well suited to divers, as they have behavioural characteristics that reduce detectability by this standard approach, particularly taking flight at distance ahead of the survey vessel. It is recommended that future surveys for divers should include scanning ahead of the survey vessel with binoculars to increase diver detectability. Additional improvements to the survey methodology to improve the quality of diver data have been suggested and trialled during 2008-09.

| Internal code | Internally assigned metadata identifier | 39799 |
| 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. | 2008-2009, Ecology Consulting, Kentish Flats, Review of Monitoring of Red Throated Divers |
| Alternative title | The purpose of alternative title is to record any additional names by which the dataset may be known. | Review of Monitoring of Red Throated Divers |
| 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. | b562555c-83d2-4d7b-9e9a-6ea54cab8f7f |
| Resource Identifier | This is the code assigned by the data owner. | TCE-811 |
| 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 | 2008-12-06 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2009-03-22 |
| Spatial resolution unit | This describes the unit of spatial resolution which for distance must be metres. | urn:ogc:def:uom:EPSG::9001 |
| 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'. | asNeeded |

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | The current data review and re-analysis has allowed the application of a more powerful statistical approach using the specific recorded locations of each diver observation. Diver densities recorded in zones within and around the wind farm and their distances from wind turbine locations (before/during and after construction) have been analysed. Although limited by the extent of the survey area and the lower coverage of the control area, this approach has enabled a revised statistical analysis to be undertaken and updated conclusions to be reached that accord better with the observations made by field observers and reported in the previous monitoring reports. |
