After isostatic correction for their sedimentary fill, the depths of two small oceanic basins in the southern Scotia Sea suggest that both started to open in mid to late Eocene times. Models of the short magnetic anomaly profiles across the basins pr

A review of evidence for deformation and terrane accretion on the Late Triassic–Early Jurassic margins of Pangea and the mid-Cretaceous margins of the palaeo-Pacific ocean shows that deformation was global and synchronous with probable superplume e

The East Scotia Ridge is an active back-arc spreading centre located to the west of the South Sandwich island arc in the South Atlantic Ocean, consisting of nine main segments, E1 (north) to E9 (south). Major and trace element and Sr–Nd–Pb isotop

Bathymetric and seismic data show that the southernmost segment of the East Scotia Ridge (segment E9) is anomalous in its curved plan form, and in the presence of a large axial volcanic ridge (AVR). Spreading commenced only within the past 1 million

We have identified first evidence for the presence of submarine hydrothermal activity along the East Scotia Ridge an isolated back-arc spreading centre located at 55–60°S in the Atlantic sector of the Southern Ocean. Using a combination of in situ

The Bouvet triple junction has been proposed to have evolved as a ridge-fault-fault (RFF) type between 20 and 10 Ma, connecting the southernmost Mid-Atlantic Ridge (SMAR) with the Bouvet and Conrad transforms, to the east and west, respectively. We s
