Tectonics of an extinct ridge-transform intersection, Drake Passage (Antarctica)
Read more of: Tectonics of an extinct ridge-transform intersection, Drake Passage (Antarctica)New swath bathymetric, multichannel seismic and magnetic data reveal the complexity of the intersection between the extinct West Scotia Ridge (WSR) and the Shackleton Fracture Zone (SFZ), a first-order NW-SE […]

Definition of Late Cretaceous stage boundaries in Antarctica using Sstrontium ssotope stratigraphy
Read more of: Definition of Late Cretaceous stage boundaries in Antarctica using Sstrontium ssotope stratigraphyNew 87Sr/86Sr analyses of macrofossils from 13 key marker horizons on James Ross and Vega Islands, Antarctica, allow the integration of the Antarctic Late Cretaceous succession into the standard biostratigraphic […]

Aerobic endospore-forming bacteria from geothermal environments in northern Victoria Land, Antarctica, and Candlemas Island, South Sandwich archipelago, with the proposal of Bacillus fumarioli sp. nov
Read more of: Aerobic endospore-forming bacteria from geothermal environments in northern Victoria Land, Antarctica, and Candlemas Island, South Sandwich archipelago, with the proposal of Bacillus fumarioli sp. novAerobic endospore-forming bacteria were isolated from soils taken from active fumaroles on Mount Rittmann and Mount Melbourne in northern Victoria Land, Antarctica, and from active and inactive fumaroles on Candlemas […]

Autopsy on a dead spreading center: The Phoenix Ridge, Drake Passage, Antarctica
Read more of: Autopsy on a dead spreading center: The Phoenix Ridge, Drake Passage, AntarcticaNew bathymetric and magnetic anomaly data from the Phoenix Ridge, Antarctica, show that extinction of all three remaining segments occurred at the time of magnetic chron C2A (3.3 ± 0.2 […]

Model and measurements show Antarctic ozone loss follows edge of polar night
Read more of: Model and measurements show Antarctic ozone loss follows edge of polar nightA three‐dimensional chemical‐transport model of the stratosphere has been used to study the 1996 austral winter and spring. Both the model and ozonesonde measurements show that ozone depletion associated with […]

Middle Jurassic ultramafic lamprophyre dyke within the Ferrar magmatic province, Pensacola Mountains, Antarctica
Read more of: Middle Jurassic ultramafic lamprophyre dyke within the Ferrar magmatic province, Pensacola Mountains, AntarcticaAn ultramafic lamprophyre dyke is described from the otherwise tholeiitic Ferrar magmatic province of Antarctica. We report an Ar-Ar age of 183 ± 2.2 Ma for the dyke, indistinguishable from […]

Magma supply in back-arc spreading segment E2, East Scotia Ridge
Read more of: Magma supply in back-arc spreading segment E2, East Scotia RidgeSegment E2 is situated in the back-arc East Scotia Ridge. The segment is unusual in that it has an axial topographic high underlain by a seismically imaged melt lens. The […]

A comparison of two spectral approaches for computing the Earth response to surface loads
Read more of: A comparison of two spectral approaches for computing the Earth response to surface loadsWhen predicting the deformation of the Earth under surface loads, most models follow the same methodology, consisting of producing a unit response that is then con-volved with the appropriate surface […]
