英文摘要	We surveyed the deposition of drill cuttings on the seafloor along a transect at eight drilling locations in the south-western Barents Sea and Norwegian Sea, comparing traditional visual surveying methods and underwater hyperspectral imagery (UHI). The locations range from newly-drilled to around 30 years post-drilling. The visual assessments detected deposited drill cuttings to extend to around 150–200 m from the drilling location at recently drilled sites and generally less than 50 m at older locations. Quantitative UHI analyses of relative change in the spectral signature of the sediments with increasing distance from the drilling location mostly showed a change-over to conditions resembling undisturbed sediments at approximately similar distances as the visual assessments. Biological faunal community analyses also reflected these trends. The UHI-based detection of drill cuttings thus in general supported the results of visual assessments and potentially could be further developed as a method for automated surveying of drilling sites. © 2019
