Its main activities include the organization of an annual scientific conference of geophysicists mostly of German speaking countries or close personal or professional ties to them and the publication of a major scientific journal, the Geophysical Journal International GJI in cooperation with the Royal Astronomical Society . The DGG also organizes seminars and workshops on specific scientific topics for its members and offers information and advice on issues related to the organization of university curricula in geophysics. Members are mostly professional geophysicists, but in principle, everybody who supports the aims of the society can become a member.

Upward continuation is a method used in oil exploration and geophysics to estimate the values of a gravitational field gravitational or magnetic field by using measurements at a lower elevation and extrapolating upward, assuming continuous function continuity . This technique is commonly used to merge different measurements to a common level so as to reduce scatter and allow for easier analysis.

In magnetic confinement fusion the zonal direction primarily connotes the Toroidal and poloidal poloidal direction i.e. the short way around the torus , the corresponding coordinate being denoted by y in the slab approximation or in magnetic coordinates. However, in the fusion context, usage is restricted to the context of Zonal flow plasma zonal plasma flows and there will in general be a Toroidal and poloidal toroidal component in such flows as well. Thus, although the term zonal has come into use in plasma physics to emphasize an analogy with Zonal flow zonal flows in geophysics , it does not uniquely identify the direction of flow, unlike the case in geophysics.

In geophysics , a magnetic anomaly is a local variation in the Earth s magnetic field resulting from variations in the chemistry or magnetism of the rocks. Mapping of variation over an area is valuable in detecting structures obscured by overlying material. The magnetic variation in successive bands of ocean floor parallel with mid ocean ridge s is important evidence supporting the theory of seafloor spreading , central to plate tectonics . These layers are used for dating rocks.

If math f i f i math represents the collected data then math average 12 frac f 1 f 2 2 math is the average of two values. Consider this value to be plotted between point 1 and point 2 and do the same with points 3 and 4 math average 34 frac f 3 f 4 2 math If math Delta x math represents the space between each station along the line then math frac average 12 average 34 2 Delta x frac f 1 f 2 f 3 f 4 4 Delta x math is the Fraser Filter of those four values.

Unreferenced date December 2009 A secondary circulation is a circulation induced in a rotating system. For example, the primary circulation of Earth s atmosphere is zonal . If however a parcel of air, that moves in a purely zonal direction, is accelerated or decelerated zonally, the Coriolis force will add a meridional component to its velocity. This meridional circulation is then the secondary circulation.
