Humpback whale (Megaptera novaeangliae) distribution and movements in the vicinity of South Georgia and the South Sandwich Islands Marine Protected Area

C. C. G. Bamford et al.

Summary: Humpback whales are recovering strongly in the western South Atlantic, and their interaction with the regional fishery for Antarctic krill is an important consideration for management. Habitat use of humpback whales varies throughout the foraging period, which highlights the importance of research for informing future management.

Megabenthos habitats influenced by nearby hydrothermal activity on the Sandwich Plate, Southern Ocean

Katrin Linse et al.

Summary: The Sandwich Plate is a highly active region in terms of tectonic activity in the Southern Ocean and Antarctica, with volcanic islands, submarine volcanic features, seismic activity, and hydrothermal vents. A recent investigation explored potential hydrothermally active sites in different depths, revealing thermal anomalies and chimney structures. However, the benthic habitats and communities of the Sandwich Plate are still poorly understood.

Spatial and temporal variability and connectivity of the marine environment of the South Sandwich Islands, Southern Ocean

Sally E. Thorpe et al.

Summary: The South Sandwich Islands, located in the highly biologically productive Scotia Sea, are part of a large Marine Protected Area. They have a complex marine environment influenced by various factors such as the Antarctic Circumpolar Current and seasonal sea ice. This study investigates the dynamics and variability of the ocean and sea ice in the region, using remotely sensed data. The results show clear seasonality in sea surface temperature and sea ice, while local chlorophyll blooms display irregular timing and location. The timing and pattern of sea ice retreat seem to be a key driver in the formation of chlorophyll blooms, influenced by local circulation and other processes.

Bioregionalization of the South Sandwich Islands through community analysis of bathyal fish and invertebrate assemblages using fishery-derived data

Philip R. Hollyman et al.

Summary: The South Sandwich Islands is a biologically rich area with clear differences in fish and invertebrate communities across its latitudinal range, driven by environmental factors such as seawater temperature. Climate change may alter these communities with poleward shifts in species ranges.

From sealing to the MPA-A history of exploitation, conservation and management of marine living resources at the South Sandwich Islands

M. Belchier et al.

Summary: The exploitation of marine resources in the South Sandwich Islands started with fur seal hunting in the 19th Century, followed by pelagic whaling and trawl fisheries for demersal finfish and krill. However, fishing activity in the region is now limited to a licensed demersal longline fishery for toothfish. The South Sandwich Islands is now protected by a Marine Protected Area and additional management measures.

Contrasting life-history traits of two toothfish (Dissostichus spp.) species at their range edge around the South Sandwich Islands

Marta Soeffker et al.

Summary: This paper focuses on two toothfish species, the Patagonian toothfish and the Antarctic toothfish, in the South Sandwich Islands (SSI) region. The study reveals that the Patagonian toothfish around the SSI is connected to the adjacent South Georgia population but has unique characteristics. On the other hand, the Antarctic toothfish at the SSI represents the northern extent of a larger stock. The relative importance of the SSI in the life cycle of both species, especially in the context of climate change, is also explored.

Using habitat models for chinstrap penguins, Pygoscelis antarctica, to inform marine spatial management around the South Sandwich Islands during the penguin breeding season

Gemma Clucas et al.

Summary: This study developed habitat models for chinstrap penguins based on their foraging behavior during the chick-rearing period and predicted their foraging habitat use around the South Sandwich Islands. The results show that the provisions of the marine protected area ensure robust protection for chinstrap penguins and other krill-dependent predators during the summer, while seasonal sea ice acts as a physical barrier to exclude the fishery during the winter. However, competition between krill predators and the fishery could exist in new resource extraction locations.

Plankton and nekton community structure in the vicinity of the South Sandwich Islands (Southern Ocean) and the influence of environmental factors

Cecilia M. Liszka et al.

Summary: The South Sandwich Islands are a biologically productive archipelago in the eastern Scotia Sea, with little knowledge of the plankton ecology. This study conducted a comprehensive investigation on the plankton community in the region, revealing spatial variations in community structure and the influence of environmental conditions on plankton distribution and function. The results suggest that the pelagic community of the South Sandwich Islands supports multiple trophic pathways and operates independently from Antarctic krill.

Hadal fauna of the South Sandwich Trench, Southern Ocean: Baited camera survey from the Five Deeps Expedition.

Alan J. Jamieson et al.

Summary: The South Sandwich Trench is an isolated and cold hadal ecosystem in the South Atlantic and Southern oceans with unique biodiversity including hadal fish, scavenging amphipods, brittle stars, holothurians, gastropods, sponges, and stalked crinoids. This study highlights the endemic community present in this high pressure-low temperature environment.

Population abundance of recovering humpback whales Megaptera novaeangliae and other baleen whales in the Scotia Arc, South Atlantic

Mick Baines et al.

Summary: The populations of humpback whales and other baleen whale species in the South Atlantic are recovering after the cessation of whaling, but limited monitoring in the Scotia Arc, a former whaling epicentre, necessitates up-to-date assessment of whale biomass and prey consumption for managing Antarctic krill fisheries. This study provides the first estimates of whale abundance and krill consumption in South Georgia and the South Sandwich Islands, as well as the total abundance of humpback whales in their southwestern Atlantic feeding grounds, highlighting the importance of further research into baleen whale feeding rates to improve prey consumption rate estimation accuracy and precision.

Enhancing the ecosystem approach for the fishery for Antarctic krill within the complex, variable, and changing ecosystem at South Georgia

P. N. Trathan et al.

Summary: The ecosystem approach to fisheries management aims to sustain healthy marine ecosystems and their associated fisheries. Implementation in the Antarctic has provided valuable insights, but additional monitoring is needed. Variability in the krill fishery at South Georgia is linked to sea surface temperature, with ecological structure influencing results.

Developing UAV Monitoring of South Georgia and the South Sandwich Islands' Iconic Land-Based Marine Predators

John Dickens et al.

Summary: The sub-Antarctic islands of South Georgia and the South Sandwich Islands are home to globally significant populations of seabirds and marine mammals. A marine protected area was created around these islands in 2012 but monitoring populations of marine predators remains a challenge. Researchers trialed the use of a drone to monitor populations of seals, penguins and albatross and found that UAV surveys can allow regular and accurate monitoring of these important wildlife populations, although there are limitations in certain habitats.

Distribution of Vulnerable Marine Ecosystems at the South Sandwich Islands: Results From the Blue Belt Discovery Expedition 99 Deep-Water Camera Surveys

Anna-Leena Downie et al.

Summary: The South Sandwich Islands are a chain of volcanic islands situated to the east of the Scotia Sea, with limited knowledge about their benthic environment. A scientific survey conducted by the Blue Belt Programme in February/March 2019 found that vulnerable marine ecosystem indicator taxa are mostly restricted to waters shallower than 700 meters.
