Welcome to CefMAT
The Cefas Marine Assessment Tool has been developed to support scientists deliver national and international assessments for the protection and conservation of our seas. It enables scientists and marine assessors to efficiently produce quality, bespoke assessments.
It enables rapid integration and visualisation of multi-platform, multi-parameter and multi-national data, at a national and regional scale which users can query and generate assessment outputs, graphs, time-series plots, bespoke assessment maps, and generate reporting material. It delivers transparent, auditable, cost-effective policy-relevant information, e.g. suitable for assessing good environmental status. Further services are available to assessors for the Marine Strategy Framework Directive (MSFD) and the Oslo and Paris Convention for the protection and conservation of the North-East Atlantic (OSPAR).
Defra and Cefas are committed to complying with the requirements of the Data Protection Act 1998 that govern the processing of personal data.
Use by you of the data (which includes model outputs and simulations) on this site is entirely at your own risk and is undertaken in accordance with the User Licence.
