The electrical conductivity of Atlantic type pyromagmas from Mount Etna, Sicily

Creator:: Mathews, Frank Samuel
Abstract:: The electrical conductivity of the pyromagmas from the Northeast Crater of Mount Etna, Sicily was measured over the temperature range 1032°C to 1071°C and over the frequency range 1 kHz to 400 kHz. Measurements were made using a four-terminal Wenner array in conjunction with a Wavetek Model 110B portable signal...

Tidal tilt observations in the Krafla geothermal area in North Iceland

Creator:: Axelsson, Gudni
Abstract:: A brief tilt and strain survey was conducted in the Krafla-Namafjall area in the North of Iceland during August of 1979 in order to study the feasibility of applying solid earth tidal observations in the exploration of volcanic geothermal systems. The rationale of the survey was based on the expectation...

Downward continuation and transformation of potential fields with application to marine magnetic anomalies

Creator:: Eggers, Dwight Edward
Abstract:: The problem of downward continuation of potential fields is being considered. The basic approach involves computation in real space using a power series expansion. The computation of the derivatives required for evaluating the series is carried out on the basis of two approximation methods, viz. (1) polynomial method, and (2)...

On the influence of terrestrial heat flow anomalies on the temperature microstructure at the ocean floor

Creator:: Vossler, Donald Alan
Abstract:: The effects on the temperature microstructure of terrestrial heat flow and heat flow anomalies at the ocean floor are discussed on the basis of a simple heat diffusion model. The effects on the temperature microstructure of layering of the thermal properties of the ocean are investigated. This is done both...

On the theory of heat transport in a semi-infinite solid

Creator:: Wong, James Teng
Abstract:: The paper concerns itself with the problem of heat transport in a homogeneous, incompressible, isotropic, semi-infinite solid whose boundary is nonstationary. The methods of solution in the one dimensional case are discussed. Numerical examples and a method for arriving at the solutions published by Bailey and Lakin in their paper...

Stability of convective flows in porous media

Creator:: Ghandour, Nabil Nassib
Abstract:: The stability of fluids in porous media subject to various physical and geometrical conditions is studied here. Criteria for the onset of convective motions are given in terms of critical temperature gradients or heat sources. The general method used involves the linearization of the field equations about the hydrostatic solutions...

Iterative techniques in linearized free surface flow

Creator:: Avera, William Edgar
Abstract:: The displacement of the free liquid surface in geothermal and hydrologic reservoirs is an important capacitance factor. An iterative approach to determining the drawdown of the free liquid surface for a single sink region in a homogeneous, isotropic, Darcy-type porous mediums is discussed. The iterative approach involves a stepwise adjustment...

On the reduction and interpretation of ocean-floor temperature and heat flow data

Creator:: Shih, Keh-gong
Abstract:: In this thesis, the interpretation and reduction of ocean heat flow measurements are discussed on the basis of theoretical models. The instrument effect x heat flow measurements is investigated for the case of long period measurements by studying the heat conduction along the measurement probe for both steady and unsteady...
