These anomalies are thus of substantial geophysical and geological interest. The Norwegian expedition continued with topographical mapping, while the others started geophysical and geological research. Seismic Unix has many of the processes needed on the geophysical processing. Both mapping and geophysical work was undertaken. He majored in geophysical survey and exploration. There are many methods and types of instruments used in geophysical surveys. Other methods include solute sampling and geophysical methods. He had the task of planning and conducting geophysical investigations during that expedition. Conversion of a Yak-42 for geophysical survey and environmental monitoring. This effect must be accounted for in detailed geophysical measurements. There are a number of geophysical methods for characterising aquifers. A variety of electric methods are used in geophysical survey. Optimization techniques are regularly used in geophysical parameter estimation problems. In geophysical reservoir engineering studies, the harmonic mean is widely used. In addition to the geophysical survey, core samples and aerial photographs were taken.
