Marine Environmental Resources Mapping and Information Database (MERMAID)

 

MERMAID has closed

The MERMAID website has closed: the data previously found here have been significantly updated and are now available from other online sources with additional functionality. The MNCR survey data previously contained in MERMAID gave a static picture of marine survey data held by JNCC in 2000, and therefore did not present a complete picture of our data holdings. The information provided by MERMAID is now available in three places: the NBN Gateway for species data; the MESH webGIS for habitat data and other MNCR survey details; and the JNCC website for the latest version of the Marine Habitat Classification.

 

NBN Gateway – http://www.searchnbn.net/

Species data

If you previously used MERMAID to retrieve taxon data (rather than habitat data), you should now use the NBN Gateway to locate and download taxon data. The NBN Gateway provides access to a substantial volume of biodiversity data for the UK, including downloadable species lists. It allows you to view and use this data alongside other relevant information on the web. There are 3 ways of navigating the site; for more details about these please see the Help on the NBN Gateway website:

  • Type a word or phrase into the search box, e.g. search for species name
  • Browse through lists e.g. browse datasets available, find a site report by name or map
  • Use map based navigation e.g. to generate species list for 10km square

 

MESH webGIS – http://www.searchmesh.net/webgis

Habitat data, survey details, limited species data

The MESH webGIS is free to use but does require users to register a few details in order to receive the login details by email. The MESH webGIS provides access to the MNCR survey data, together with significant additional data holdings which are stored in JNCC’s marine database, Marine Recorder. Data have now been reclassified to the 04.05 version of the marine habitat classification. You can find records by spatial searches of an interactive map, rather than searching for the name of a survey/site/biotope/species. However, the focus of the MESH webGIS is the delivery of seabed habitat maps (polygon areas rather than point samples) and it is possible to search these habitat maps for habitats of interest, as well as to overlay data of numerous different types to give context to the sample points (such as depth, sediments, seabed photos). It is not possible to download data. The table below shows where the information previously available on MERMAID can be found on the MESH webGIS. Full details of how to access these different types of information (PDF). Some additional features of the MESH webGIS which might be of interest are included:
 
MERMAID
MESH webGIS
Surveys
Survey details page: accessible from the JNCC biotope samples layer in ValidationSamples folder (via Sample details page)
 
Sites
MNCR site names are not searchable on MESH webGIS but are available on Sample details page.
 
Search for an area name: from the query page (select country, then type, then place name: e.g. UK > Estuary > Milford Haven)
 
Biotopes (=habitats)
Sample details page: accessible from the JNCC biotope samples layer in ValidationSamples folder
 
Search for habitats: from the query page
 
Species
Sample details page species list with abundance & whether species are characterising: accessible from the JNCC biotope samples layer in ValidationSamples folder
 
Two reports using data from NBN Gateway species list & diversity summary for selected area: accessible from any layer
 
No equivalent
Printable report of habitat details for selected points: accessible from the JNCC biotope samples layer in ValidationSamples folder
 
No equivalent
Printable report of a summary of habitats for selected points: accessible from the JNCC biotope samples layer in ValidationSamples folder
 
 

Marine Habitat Classification –  http://jncc.defra.gov.uk/marinehabitatclassification

The updated Marine Habitat Classification for Britain and Ireland (version 04.05) is available online. It includes the biotope descriptions, search pages and an expandable hierarchy. Downloadable documents are also available. The classification was originally developed by the Marine Nature Conservation Review (MNCR) and published in two paper volumes in 1997 (Connor et al., 1997 a,b). The current version of the marine habitat classification supersedes the 1997 version, as well as the interim version published on this website in 2003 (version 03.02). The latter version has now been removed from the website.
