Metadata: 2009 Center for Environment, Fisheries and Aquaculture Science: Areas surveyed with multibeam to map the seabed habitat
Abstract:
Cefas collects multibeam bathymetry and backscatter data as part of seabed and habitat mapping surveys. These surveys are predominantly conducted as part of environmental assessments of human activities or in the context of the identification and assessment of areas of conservation interest. Cefas has the capability to collect multibeam data from its Research Vessel Cefas Endeavour, but data may also be collected by sub-contractors. Polygon areas represent approximate extents of survey data gathered. In some areas only data corridors were collected, rather than data for the entire polygon. Data are generally acquired for seabed characterisation and habitat mapping purposes. Surveys may not meet all requirements of the IHO Order 1 Standard. Surveys are generally reduced to Mean Sea Level (MSL).

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 Center for Environment, Fisheries and Aquaculture Science: Areas surveyed with multibeam to map the seabed habitat |
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. | 5f49de0fd7d5c542e74c6aa8107081c1 |
Resource Identifier | This is the code assigned by the data owner. | NETGAIN0029 |
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. | dataset |
Start date | This describes the date the resource starts. This may only be the year if month and day are not known | 2009-01-01 |

Abstract | The abstract provides a clear and brief statement of the content of the resource. | Cefas collects multibeam bathymetry and backscatter data as part of seabed and habitat mapping surveys. These surveys are predominantly conducted as part of environmental assessments of human activities or in the context of the identification and assessment of areas of conservation interest. Cefas has the capability to collect multibeam data from its Research Vessel Cefas Endeavour, but data may also be collected by sub-contractors.

Surveys are generally reduced to Mean Sea Level (MSL). |
Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | The polygons represent the approximate extents of areas where survey data was obtained by Cefas or a sub-contractor which undertook the survey. Polygons were created from the bathymetric products created by Cefas or the survey sub-contractor and digitised by Cefas. Cefas staff populated an attribute table (developed and provided by MCA) with the following attributes: HI_Name - Hydrographic Instruction name. Combination of the name of the survey area and the unique Cefas Cruise Code. Often, the survey area name relates to a dreged material disposal site, a licensed aggregate extraction site, a windfarm development area or a major nearby natural feature. HI_Number - A unique HI reference number which is used internally by the MCA and UK Hydrographic Office (UKHO). HI numbers are not used by Cefas and left blank. Contract - The Cefas contract code under which this work was undertaken. Contractor - The organisation which undertook the work. Standard - The overall standard to which the survey data was gathered. Start_Date - The day which the contractor started offshore operations on the polygon area. End_Date - The day which the contractor completed offshore operations on the polygon area. FY_Comissi - The financial year (April 1st to March 31st) in which the survey work was first comissioned. Status - Flag to indicate whether the survey has been completed (Surveyed) or is planned for the future (Planned) Area_KmSq - The total area of the polygon (in WGS UTM -3 deg) |
