PurposeResearch
ObjectivesObjectives

1. To find and identify seafloor animals from around the South Orkney Islands and to name and describe any species new to science.
2. To detect any significant differences between the types of species and numbers of animals in different habitats.
3. To identify species that are indicative of specific habitat types to help with future habitat mapping.
4. To map all vulnerable species found and to report their presence and distribution to relevant stakeholders such as CCAMLR.

Biology and fisheries 
ZoobenthosQuantity: number of deployments = 21
Description: Shallow water camera system (SUCS) designed to estimate benthic community density, biomass and taxa abundance. Deployments at 500m, 750m and close to 1000m. SUCS images taken to complement morphological and molecular anaysis of AGT samples.Sites: 6 locations in relation to the South Orkney Islands (West, South, North, North East, North West, North West Trough)
ZoobenthosQuantity: number of deployments = 13
Description: Epi-Benthic Sledge (EBS) with 0.5mm net, carrying Deep Water Camera System (DWCS) and CTD. Designed for sampling of epibenthic and suprabenthic organisms. Samples to be preserved and analysed for taxa abundance.
ZoobenthosQuantity: number of deployments = 30
Description: Rauschert Dredge with 0.5mm mesh net attached to Agassiz Trawl (AGT) designed to catch epibenthic organisms and molluscs.Samples to be preserved and analysed for community composition and taxa relationshiops.
ZoobenthosQuantity: number of deployments = 81
