Glacial isostatic adjustment and the anomalous tide gauge record of eastern North America
Article Abstract:
The sea-level variations measured by the international network of tide gauges need to be corrected to eliminate the 'contaminating' effects of continuing glacial isostatic adjustment (GIA). It is shown that flaws in the numerical prediction for GIA commonly relied upon in the past are responsible for the highly anomalous long-term sea-level trends observed in sites on the east coast of North America. These trends can therefore be ruled out as signs of neotectonic processes or Gulf Stream ocean circulation..

Going halves over Hudson Bay
Article Abstract:
Researchers have developed a new method for explaining the variation in gravitational pull at the surface of the Earth over areas such as Hudson Bay, North America. The global free-air gravity field was analyzed and the geographical variation in the field's spectral content was examined. Canada's post-glacial rebound was found to be consistent with a substantial material strength increase and mantle depth, with incomplete post-glacial rebound found to be responsible for 50% of the region's peak anomaly.

Deep-mantle high-viscosity flow and thermochemical structure inferred from seismic and geodynamic data
Article Abstract:
Research into the thermal convection in the Earth's mantle is discussed. A viscous-flow model based on seismic data implies there is a high-viscosity layer near 2,000 km depth.
