On Discrete Schemes in Downward Continuation of Gravity
2005Two discretization schemes of the Poisson integral have been proposed to date. Although they are mathematically solvable, they produce different gravity on the geoid for the same input data. This discrepancy arises because of different discretization techniques of the Poisson kernel; still, this problem has not received adequate attention. The question

Geophysical Activity in Canada Continues Downward Trend
Geophysics, 1976Abstract The decline in geophysical activity in Canada has exceeded the most pessimistic predictions, according to the Canadian Society of Exploration Geophysicists. This decline is blamed on a provincial-federal confrontation over sharing increased petroleum revenues.
