Baseline environmental survey of the Heidrun Field, June 1988. Volume 1: Main report
Abstract
Results from an investigation of the sea bottom sediments at 25 sites in the Heidrun oil and gas fields, June 1988, showed that levels of petroleum hydrocarbons and heavy metals were expected background. At one site elevated barium content seemed to reflect previous exploratory drilling. The sediment fauna was very rich and diverse, and showed no sign of disturbance. A slight faunal gradient from SW to NE reflected a change in sediment grain distribution.
