    Voyage overview

    Read details about the aims of the voyage and find information about the scientists and crew on board.
  • Measuring and analysing the Southern Ocean seas and atmosphere

    Data collected continuously from this voyage will fill a critical knowledge gap, helping scientists to produce better global climate and oceanographic models to ultimately improve weather forecasting.
  • Studying Antarctic silverfish spawning in Terra Nova Bay

    This research will investigate whether Antarctic silverfish eggs are spawned elsewhere or whether there is a mass migration of silverfish to their coastal spawning sites each winter.
  • Trawl surveying demersal fish species on the Ross Sea slope

    Commercial toothfish fishing in the Ross Sea has the potential to affect some demersal (bottom-dwelling) fish species in the region through by-catch and ecosystem changes.
