Direct measurements bearing on the question of the nighttime heating mechanism in the ionosphere
(Elsevier, 1967-01)
Langmuir probe measurements of electron temperature and density were made in the upper F-region on two different occasions near local midnight. The experiments were carried out at Fort Churchill, Canada, and at Wallops ...
Thermal stresses at the oceanic-continental margin
(Elsevier, 1967-03)
Dissimilar temperature profiles beneath oceans and continents give rise to thermoelastic stresses at and adjacent to the oceanic-continental margin. Computations of the magnitude and orientation of the maximum shear stress ...
