The tectonic evolution of Western Ishtar Terra, Venus
Autor: A. Lenardic, D. L. Bindschadler, W. M. Kaula
Publikováno v: Geophysical Research Letters. 18:2209-2212
The origin and evolution of Ishtar Terra is modeled using numerical simulations of crust/mantle interaction on Venus. Based on our modeling, we favor a two phase evolutionary sequence for Ishtar. The first phase is driven by bulk mantle flow due to t

The History and Dynamics of Global Plate Motions
The effects of continents on mantle heat flow are explored through a synthesis of heat flow data analysis and theoretical modeling. The data employed are from the Canadian Shield and the Canadian Appalachians and consist of both surface heat flow mea

Tectonic plates, D″ thermal structure, and the nature of mantle plumes
Autor: A. Lenardic, W. M. Kaula
Publikováno v: Journal of Geophysical Research. 99:15697
It is proposed that subducting tectonic plates can affect the nature of thermal mantle plumes by determining the temperature drop across a plume source layer. The temperature drop affects source layer stability and the morphology of plumes emitted fr

National Geodetic Survey Policy on the Role of Government in Geodesy
Autor: W. M. Kaula
Publikováno v: Journal of Surveying Engineering. 112:74-78
Most activities supported by geodesy are under state jurisdiction, but the main governmental organization that is purely geodetic is federal: the National Geodetic Survey (NGS). NGS (before 1970, as the U.S. Coast & Geodetic Survey) established the f

Reconciliation of Stokes' function and astro-geodetic geoid determinations
Autor: W. M. Kaula
Publikováno v: Journal of Geophysical Research. 64:61-71
The combined application of astronomic, geodetic, and gravimetric data to computations of the geoid is discussed. The general principle observed is that any adjustment should weight all observations inversely as their variances. Two conditions are im
