The benthic invertebrate fauna of subantarctic Marion and Prince Edward Islands
There have been several expeditions to Marion and Prince Edward Islands (MPE) which have sampled the marine fauna and flora, including those of the British ships Challenger (1873-1876) and Discovery (1935), and subsequent surveys by the French ship Marion-Dufresne (Arnaud and Hureae, 1979). South …

Comparative foraging ecology of macaroni and rockhopper penguins at the Prince Edward Islands
… segregation in space, time and/or diet. At the Prince Edward Islands, approximately 302,000 pairs of macaroni Eudyptes chrysolophus and 80,000 pairs eastern rockhopper E. chrysocome filholi penguins breed sympatrically. These populations are closer to parity than at any other locations where two …

Long-term climate variability at the Prince Edward Islands in the Southern Ocean
… has many implications on the sub-Antarctic Islands in the SO. Due to the distance away from continental land these islands experience an oceanic climate, making them the perfect sentinels to climate change in this sector of the Southern Ocean. Studies have proposed that climate changes …

Habitat association and distribution of Nauticaris marionis at the Sub-Antarctic Prince Edward Islands
… and substratum types of the Sub-Antarctic Prince Edward Islands were investigated. Twenty five stations, varying in substratum type, depth and location on the shelf and slope around the islands were sampled photographically with a towed benthic camera sled. At each station the substratum …

Climate change impact on ecosystems of Prince Edward Islands: role of oceanic mesoscale processes
The subantarctic Prince Edward Islands (PEIs, 47◦S-38◦E) are classified as isolated and hostile regions, in which the terrestrial and marine ecosystems are relatively simple and extremely sensitive to perturbations. The island’s location, between the Subantarctic Front (SAF) and the Polar Front …

The hydrography and dynamics of the general oceanic environment of the Prince Edward Islands
The Southern Ocean is the name given to the oceanic region that surrounds the entire Antarctic continent. It comprises the southern extents of the Atlantic, Indian and Pacific Oceans. The Antarctic continent forms the southern boundary of the Southern Ocean, while the northern border is not …

Investigations into the functioning of phytoplankton, zooplankton, kelp and benthic communities at the Prince Edward Islands
… pertaining to the marine communities at the Prince Edward Islands are addressed. Firstly, the nature of the 'island-mass effect', and the cause of the frequently recorded diatom blooms in the area are examined. It had been suggested that the cause of the blooms is related to the presence of a …

Surface and sub-surface hydrographic variability at the Prince Edward Islands: perspectives from the high resolution GLORYS model
The Prince Edward Islands (PEI), comprising of Marion and Prince Edward Island, are located in the direct path of the eastward flowing Antarctic Circumpolar Current, nestled within the Antarctic Polar Frontal Zone of the Southern Ocean. The islands are home to a multitude of species which are …

South Africa's proposed new Marine Protected Area around the Prince Edward Islands: An analysis of legal obligations, options and opportunities
… of a large multi-zoned MPA around the Prince Edward Islands. In particular I examine South Africa's obligations in terms of international and regional treaty law as well as its commitments to global policy statements. Legal options and opportunities for providing the most comprehensive, …

South Africa's proposed new Marine Protected Area around the Prince Edward Islands: an analysis of legal obligations, options and opportunities
… MPAs in the world around its sub-Antarctic Prince Edward Islands. It was clear from the announcement that the objective of the proposed MPA was for both fisheries management purposes as well as conservation of marine ecosystems and biodiversity in the area. As a first step the Minister …

Investigation of the impact of fur seals on the conversation status of seabirds at islands off South Africa and the the Prince Edward Islands
… on the conservation status of seabirds at islands off the coast of South Africa and at the Prince Edward Islands. At Malgas Island, the impact of predation was investigated over three breeding seasons (2000/01, 2003/04 and 2005/06), and at Dyer Island over two breeding season (2004 and …

The impact of longline fishing on the seabirds breeding on Marion Island
… on the seabirds breeding on the sub-Antarctic Prince Edward Islands. The development of a demersal longline fishery for Patagonian toothfish Dissostichus eleginoides close to the islands with almost complete observer coverage during the study allowed a detailed examination of the impacts of …

The population status, breeding success and foraging ecology of Phoebetria albatrosses on Marion Island
… of predatory fish and squid. Sub-Antarctic islands are important breeding grounds for many seabirds, including albatrosses. Monitoring of seabirds breeding on sub-Antarctic islands is important to detect changes in population dynamics to be able to implement timely conservation measures. …

The intertidal and shallow subtidal food web of sub-antarctic Marion Island
The sub-Antarctic Prince Edward Island group, consisting of Marion Island and Prince Edward Island (Fig. 1), was annexed by South Africa in 1947-1948 and subsequently declared a nature reserve. Isolated oceanic islands have always presented interesting opportunities for biological research on both …

Interannual variability and long-term trends of surface hydrography around the Prince Edward Island Archipelago, Southern Ocean
The Prince Edward Islands (PEIs) Archipelago are situated in a prime location for the study of ecosystem response to intrinsic climate variability in the Southern Ocean and the impact of climate change. They are positioned in the Polar Frontal Zone, which is constrained by the subAntarctic Front …
