Tittel: Offshore sediment survey of Region I, 2008

In 2008, Akvaplan-niva carried out a regional offshore sediment monitoring survey in Region I of the North Sea. This report presents chemical and biological analyses carried out on material from a total of 161 stations. Samples were collected at 13 individual fields (Ekofisk C & 2/4 B&K, Eldfisk 2/7 B, Tor, Embla, Albuskjell, Ula, Valhall, Tambar, Hod, Valhall Nordflanken, Valhall Sørflanken, Gyda, Oselvar) and at 12 Regional stations
Elevated barium levels in the sediment were found at all fields. THC contamination or disturbed fauna (where analysed) were not found at Valhall Nordflanken, Tambar and Oselvar. The remaining fields had various extents of impacts, but in general there has been a reduction in the area of impact since the previous survey in 2005.
