Campaigns of dated-drilling in the stations from repetition from the southern
and antarctic lands French (1998-1999)

Station of Martin Port : on the site of the absolute pillar of the derrick of dated-drilling
installed in 1991 by French Polar Forwardings (pavu - iatsu).
The average values of the magnetic field to the derrick of Martin Port in 1992,
calculated by professor J. Perconte, were: X = +845 nT, Y = +646 nT and F = 69183 nT.

The reduction of the observations made at the time of the reoccupying of 1995
only made it possible to determine elements X and F;
it was in the same way in 1996 and 1997.
Only measurements of F could be taken in 1998.
The attempts made in 1998 and 1999 to re-occupy the station of
Martin Port finally gave access the sites of dated-drilling.
