Sailing with Sikuliaq

Sensitive Operations in the Arctic

Research Opportunities

  • Arctic Ocean influences on oceanic and atmospheric circulation: Decadal variations in sea ice cover have profound effects on climate, global warming and global ocean circulation.
  • High productivity of Alaskan continental shelves: Effects of these processes on ecosystems and fisheries are not well understood.
  • Marine geological studies: Arctic oceanic sediments can reveal the history of paleoclimates. Better understanding of sub-sea volcanic activity and natural seismicity can predict potentially devastating tsunamis and other hazards.
  • Increasing anthropogenic contaminants: Great potential for adverse environmental effects.
  • Native subsistence users: Diversity and abundance of marine biota, including fish stocks, marine mammals and bird populations, will be critical to their traditional way of life.

Science Capabilities

  • Modern suite of science winches suitable for 10,000m of cable including: deep-sea traction winch; CTD winch; and hydro winch.
  • Flexible over-side handling equipment, including articulated stern A-frame.
  • Full suite of modern deck cranes on Aft deck.
  • Covered and heated equipment staging and deployment area (Baltic Room) featuring hydro-boom (Load Handling System).
  • Accommodation for three ISO standard 20 foot science vans.
  • Dynamic positioning capability.
  • Two multi-beam sonars (Kongsberg midwater EM302 and shallow water EM710), which are protected by ice-capable acoustic windows.
  • Acoustic Doppler current profilers, 75 kHz and 150 kHz. The Sikuliaq will be delivered with a transducer well that can accommodate a 38 kHz ADCP.
  • Jumbo piston coring capability.
  • Undulating towed vehicle (Triaxus) deployment capability.
  • MOCNESS multiple net towing system.
  • Precision vessel motion sensors.
  • Ethernet based, fiber-optic Local Area Science Network (LAN).
  • Modern vessel control system.
