The survey comprises 16 fields in addition to the region its self. Corresponding surveys have previously been undertaken in 1997, 2000 and 2003. In total 235 sites were sampled. On deck sample colour, sample odour, visible fauna, sediment type or special conditions of the sample were recorded. In addition samples for measurement of sediments grain size, organic content, oil hydrocarbons and heavy metal were taken. Samples for bottom fauna identifications and enumerations were also collected. Most samples were taken in the immediate vicinity of the installations as to describe the conditions at the seafloor around the installations (212 sampling sites). In an attempt to describe the natural condition in the region samples were collected from 23 sites far off the installations.
