Metadata: 2002, EMU, Kentish Flats, Hydrographic and Geophysical Survey
Abstract:
Emu Ltd conducted a hydrographic and geophysical survey for GREP at Kentish Flats in the Thames Estuary, near Herne Bay, between 15 February and 24 March 2002 to support planning and engineering for a proposed offshore wind farm and associated cable route. Utilizing methodologies such as single-beam bathymetric, side scan sonar, seismic, and topographic surveys, the survey covered a 10 square kilometre area and included high-precision GPS and total-station equipment. The findings revealed a predominantly flat and featureless seabed with minor sand ripples, localised debris, notable sub-seabed features (including a buried channel and sediment thickness variations), and minimal hazards except minor obstructions and archaeological features. The study concluded these results provide essential baseline data for foundation design, future monitoring, and cable routing, and recommended that the data be used as a primary planning resource for wind farm construction, with all positions referenced to National Grid, ETRS89, and OSGB36 datums.

| Other details | ||
| Internal code | Internally assigned metadata identifier | 19039 |
| 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. | 2002, EMU, Kentish Flats, Hydrographic and Geophysical Survey |
| Alternative title | The purpose of alternative title is to record any additional names by which the dataset may be known. | Hydrographic and Geophysical 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. | 7ecfa755-085a-4a3a-863f-5c125105f523 |
| Resource Identifier | This is the code assigned by the data owner. | TCE-777 |
| 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 | 2002-02-15 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2002-03-24 |
| 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'. | unknown |

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | Digital and analogue data are of a high quality, showing seabed features clearly and correlation between adjacent and perpendicular survey lines. When a mosaic was produced a lot of the detail of the area was lost due to the size of the data set and limitations in plotting. Therefore a seabed classification drawing was produced based on this data. Close inspection of each digital file confirmed that the site area is a flat and featureless area of seabed which has some minor sand ripple activity to the eastern and western extremities near the two sand bank features. |
