2004 Strategic Environmental Assessment SEA5 Analysis - Particle size and organic matter (North Sea)
This report is a contribution to the Strategic Environmental Assessment (SEA5) conducted by the Department of Trade and Industry (now Department of Energy and Climate Change). This report describes the results of particle size and organic content analysis on samples obtained during the 'Biology' Leg of the SEA5 programme (RV Jean Charcot, September 17th - October 8th 2003; Outer Moray Firth and Northern North Sea). 216 samples sediment samples where analysed for particle size distribution and organic content. Standard geological methods were used to derive the following: percent total carbon, percent nitrogen, percent carbonate, percent organic material, particle size distribution and mud:sand:gravel ratio. Data are summarised within an Excel spreadsheet.

Strategic Environmental Assessment (SEA) data portal
- The Strategic Environmental Assessment (SEA) data portal provides free access to available data and reports which have been produced through the UK Department of Energy and Climate Change SEA process. The site is run and managed by BGS on behalf of the Department of Energy and Climate Change (DECC). Many files can be downloaded directly from this website. Those that are too large to download can be ordered via the website for postal delivery from BGS.

Data Quality
As part of the UK Department of Energy and Climate Change's Offshore Energy Strategic Environmental Assessment programme 216 samples were collected from RV Jean Charcot, September 17th - October 8th 2003 were provided by Geotek Ltd./ERT Scotland for the analysis of sediment particle size distribution and organic content. Standard geological methods were used to derive the following: percent total carbon, percent nitrogen, percent carbonate, percent organic material, particle size distribution and mud:sand:gravel ratio.. The LS230 laser diffraction machine was regularly serviced and calibrated with known standards. Quality assurance protocols outlined in ISO13320 were followed. The report was prepared by Partrac.
