Variations in crustal structure across the transition from West to East Antarctica , Southern Victoria Land
S U M M A R Y The crustal structure beneath Ross Island and the Transantarctic Mountains (TAM) in Southern Victoria Land, Antarctica, is inferred using non-linear inversion of receiver functions, derived from teleseismic earthquake data. Intermediate-period waveforms from more than 160 teleseismic earthquakes recorded between January 1994 and January 2000 were used in the analysis. The inversio...
متن کاملDeglacial temperature history of West Antarctica.
The most recent glacial to interglacial transition constitutes a remarkable natural experiment for learning how Earth's climate responds to various forcings, including a rise in atmospheric CO2 This transition has left a direct thermal remnant in the polar ice sheets, where the exceptional purity and continual accumulation of ice permit analyses not possible in other settings. For Antarctica, t...
متن کاملConstraining the crustal thickness on Mercury from viscous topographic relaxation
[1] Mercury exhibits long-wavelength topography which has probably survived for 4 Ga. Assuming Airy compensation, the survival of the topography indicates that only certain combinations of crustal thickness and thermal structure are allowable. A dry diabase rheology allows a thicker crust than a dry plagioclase rheology. The existence of ancient faults places some constraints on the thermal str...
متن کاملAccelerated sea-level rise from West Antarctica.
Recent aircraft and satellite laser altimeter surveys of the Amundsen Sea sector of West Antarctica show that local glaciers are discharging about 250 cubic kilometers of ice per year to the ocean, almost 60% more than is accumulated within their catchment basins. This discharge is sufficient to raise sea level by more than 0.2 millimeters per year. Glacier thinning rates near the coast during ...

To ascertain whether the , ·elocity of Ice Stream B, \\'est Antarctica, may be controlled by the stres e in its marginal shear zones \ the .. Snake" and the ..
