First quantification of subtidal community structure at Tristan da Cunha Islands in the remote South Atlantic: from kelp forests to the deep sea [PDF]

PLoS ONE, 2018
Tristan da Cunha Islands, an archipelago of four rocky volcanic islands situated in the South Atlantic Ocean and part of the United Kingdom Overseas Territories (UKOTs), present a rare example of a relatively unimpacted temperate marine ecosystem.

Vagrant Antarctic fur seals at the Tristan da Cunha Islands [PDF]

Polar Biology, 2014
Antarctic fur seals Arctocephalus gazella mainly breed at islands south of the Antarctic Polar Front, but stragglers occasionally occur farther north, with records from Gough Island (40°S, 10°W) in the central South Atlantic Ocean in October/November 2005 and September/October 2009.

CLIMATIC DATA COMPARISON BETWEEN MID-LATITUDE AZORES (NORTH ATLANTIC) AND TRISTAN DA CUNHA (SOUTH ATLANTIC) ISLANDS

Studia Universitatis Babeş-Bolyai: Geographia, 2023
The Azores islands in the North Atlantic and the Tristan da Cunha islands in the South Atlantic are approximately located at the same latitude, stretching between 36 and 41 degrees North and South respectively. Nevertheless, there are important climatic

Climate Mitigation through Biological Conservation: Extensive and Valuable Blue Carbon Natural Capital in Tristan da Cunha’s Giant Marine Protected Zone [PDF]

Biology, 2021
Carbon-rich habitats can provide powerful climate mitigation if meaningful protection is put in place. We attempted to quantify this around the Tristan da Cunha archipelago Marine Protected Area.

Dramatic ENSO related Southwestern Atlantic ecosystem shifts [PDF]

Scientific Reports
ENSO (El Niño Southern Oscillation) events are becoming more frequent and more intense as climate change continues. Although ENSO effects are known to propagate into the southwest Atlantic, knowledge of how these anomalies result in ecological impacts is

Uncovering genetic population structure in the Endangered northern rockhopper penguin (Eudyptes moseleyi) across islands in the Southern Atlantic and Indian oceans [PDF]

BMC Genomics
Background The northern rockhopper penguin (Eudyptes moseleyi) is a threatened species, listed as Endangered globally by the IUCN owing to rapid population decreases in the past, combined with a limited distributional range. Their breeding is confined to

Cetaceans Sightings During Research Cruises in Three Remote Atlantic British Overseas Territories

Frontiers in Marine Science, 2021
Marine mammal sightings were recorded during research cruises to three remote, mid-ocean British Overseas Territories in the South Atlantic and Southern Ocean. In March to April 2018 and 2019, the Exclusive Economic Zones (EEZs) of tropical St Helena and

The diet of the Tristan da Cunha Islanders [PDF]

British Journal of Nutrition, 1966
1. An assessment of the Islanders' food consumption on Tristan da Cunha before the volcanic eruption of 1961 was made (Part 1). The mean daily intake of energy was 2030 kcal per person and the calories derived from protein, fat, carbohydrate and alcohol accounted for 21, 26, 50 and 3% respectively of the total calorie intake, the proportion of calories

Climate Change Impacts on Atlantic Oceanic Island Tuna Fisheries

Frontiers in Marine Science, 2021
Climate change is already affecting the distributions of marine fish, and future change is expected to have a particularly large impact on small islands that are reliant on the sea for much of their income.
