Metadata: 2009, EMU Ltd, The Outer Thames Estuary Regional Environmental Characterisation Survey Element
Abstract:
The aim of the Thames Regional Environmental Characterisation (REC) survey, funded through the Marine Environment Protection Fund of the Aggregate Levy Sustainability Fund, survey was to acquire data, of the highest quality and resolution possible, to enable broadscale characterisation of the seabed habitat, associated biological communities and potential historic environmental assets within the region. The specific objectives of the project were to: Acquire high quality data within the logistical, time and cost constraints of the project; Acquire acoustic and geophysical data capable of describing broadscale seabed habitats and potential historic environment assets within the region, and so develop the understanding of the physical processes that influence the regional seabed, historic environment and its faunal communities; Acquire seabed imagery to describe the types of seabed habitats and epifauna that exist within the region and enable the future interpretation of acoustic and geophysical data; Acquire seabed grab samples to describe the seabed, and faunal community?s habitats, in the region and enable the future interpretation of acoustic and geophysical data; Acquire scientific beam trawl samples to describe the epifaunal communities; Acquire data capable of determining the location and significance of rare or regionally unique habitats or those that might be considered for protection under the terms of national conservation legislation; Acquire data capable of determining the significance of habitats and benthic species identified in maintaining the health of higher tropic levels of regional marine communities; Acquire geophysical, geological and biological data to support the integrated management of offshore resources in the region and to provide a better basis for marine spatial planning.

| 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. | 2009, EMU Ltd, The Outer Thames Estuary Regional Environmental Characterisation Survey Element |
| 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. | a9d278780a4950aebd0ec8a840200871 |
| Resource Identifier | This is the code assigned by the data owner. | 20434 |
| 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 |

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | Although the project was hampered by unseasonal weather during the geophysical data acquisition phase, approximately 1400 line kilometres of single beam bathymetry, swathe bathymetry, sonar, boomer sub-bottom profiler and magnetometry data was acquired. This is approximately 54% of the original programme. Data quality is generally very good or good. There were few instrument malfunctions. Survey operations invariably ceased before data quality or personnel safety became compromised. In addition to the remote sensing programme, 70 sites were sampled for geological and environmental purposes and seabed photographs were collected. The positions of a number of these pre-selected sites were moved due to difficulties with vessel access. Beam trawls were successfully completed at 30 stations. |
