StatusCompleted
Port of departureImmingham, United Kingdom
Port of returnStanley, Falkland Islands (Malvinas)
PurposeResearch
ObjectivesThe cruise was the first polar project of the Darwin Initiative and its aim was threefold.

1. To assess, using multiple apparatus types and molecular methods, benthic biodiversity of the least known areas from inner shelf to shelf break of South Georgia.
2. To quantify change over the terminal moraines left behind marking the maximum advance of ice during the last glaciation around South Georgia.
3. To map distributions, densities and rarity of species and habitat types to provide the scientific underpinning for marine protected areas.

The cruise uses similar spatial sampling structure, apparatus and observers to a previous one to Marguerite Bay, West Antarctic Peninsula allowing strong comparability. This was the main cruise of Darwin project 18-019 in Oct/Nov 2011 which is collaborative project between British Antarctic Survey, Government of South Georgia and South Sandwich Islands and the Shallow Marine Surveys Group of the Falkland Islands.
