Recovery of deep-water megafaunal assemblages from hydrocarbon drilling disturbance in the Faroe−Shetland Channel

Abstract: Recovery of megabenthic assemblages from physical disturbance at the Laggan deep-water hydrocarbon drilling site in the Faroe−Shetland Channel was assessed using remotely operated vehicle quantitative video survey. Twelve undisturbed control sites and 2 well sites (A and C, disturbed 3 and 10 yr prior to this work, respectively) were analysed and compared with a previous survey immediately following disturbance at A. The megabenthic epifauna at Laggan was dominated by sponges (69.6% total fauna) represented by… Show more

“…Cuttings are solid material removed from drilled rock together with any solids and liquids derived from any adherent drilling fluids. Cuttings can have a significant impact on taxa, abundance, biomass and diversity around oil installations (Schaanning et al, 2008;Trannum et al, 2010), with those impacts lasting for many years (Jones et al, 2012).…”

“…Since 1996, there have been no discharges of oil-mudcontaminated cuttings (OSPAR Commission, 2001a), and since 2004, virtually no OPFs and cuttings have been discharged in the North Sea region (OSPAR Commission, 2012). However, research into impacts on cold-water coral colonies has shown that cuttings can have a major impact on colony size and mortality (Gass & Roberts 2006;Allers et al, 2013;Larsson et al, 2013), while drilling activities more generally can have an impact on the density of motile organisms close to drilling platforms (Jones et al, 2012).…”

“…Research has primarily focused on impacts occurring during the active exploration and production phase, for example physical disturbance from drill-cutting discharge (e.g. Jones et al, 2012), and impacts of obsolete structures left in place, for example fish attraction-production (see Gallaway et al, 2009). …”

“…In the Norwegian Sea (380 m depth), there was a reduction in the visible footprint of drill cuttings from a radius of over 50 m to ∼20 m over 3 years, but chemical contamination persisted over the larger area (Gates and Jones, 2012). In the Faroe-Shetland Channel (500-600 m), visible drill cuttings reduced from a radius of over 85-35 m over a 3-year period, while an adjacent 10 yearold well-site exhibited visually distinct cuttings piles at a radius of only 15-20 m (Jones et al, 2012a). Recovery of benthic habitats may take longer at sites where bottom water movements limit dispersal of cuttings (Breuer et al, 2004).…”
