Strategic environmental assessment (SEA) data portal

BGS Technologies — Databases

In 1999, the Department of Trade and Industry (now the Department for Business, Energy & Industrial Strategy (BEIS)) began a sequence of sectoral strategic environmental assessments (SEAs) of the implications of further licencing of the UK Continental Shelf (UKCS) for oil and gas exploration and production.

The SEA process subdivided the UKCS into eight areas. Beginning in 2008, integrated offshore energy SEAs have been undertaken that cover the whole UKCS.

An integral part of the SEA programme has been a series of research and monitoring surveys commissioned to acquire new data about the offshore environment and used to help inform the relevant SEAs. Technical reports describing the surveys are available from the current offshore energy SEA.

To enable free and open access to data collected during the SEA surveys, BEIS commissioned us to develop and maintain this data portal with the aim of providing all reports and datasets associated with each SEA.
