New Constraints on the Origin of the EM‐1 Component Revealed by the Measurement of the La‐Ce Isotope Systematics in Gough Island Lavas

Geochemistry Geophysics Geosystems, 2019
Hot spot lavas show a large diversity of isotope compositions resulting from the recycling of surface material into the convective mantle. Amongst the mantle end‐members, EM‐1 (enriched mantle) is widely debated and scenarios involving either old pelagic

Trophic ecology of sooty albatross, segregating mechanisms from the congeneric light-mantled sooty albatross, and conservation implications

Endangered Species Research
The trophic ecology of the Endangered sooty albatross (SA, 4 populations) was investigated using the concept of isotopic niche as a proxy of the trophic niche, and its isotopic metrics were compared with those of the congeneric Near Threatened light ...

Gough Island—A Possible Sanctuary [PDF]

Oryx, 1957
The Tristan da Cunha group includes four islands; Tristan itself with its near neighbours Nightingale and Inaccessible, and Gough Island which lies 230 miles to the S.S.E. The group was discovered by Portuguese seamen in the early sixteenth century, but permanent occupation did not begin until 1810, when a small settlement was founded on Tristan.

A new species of Cresponea (Roccellaceae, Ascomycota) from Gough Island [PDF]

, 2011
The new species, Cresponea sorediata Elix, Øvstedal & Gremmen, based on material from Gough Island, is described. It is characterized by a sorediate thallus, but no apothecia has been found.

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

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.
