The Ampére smt was not completely surveyed with magnetometer due to rough
sea. For the same reason Unicorn smt was not surveyed at all while Seine
smt was surveyed with optimal line spacing. However, the very preliminary
results indicate that Ampére smt has a strong magnetic signature with a 
700-800 nTesla anomaly with respect to the regional field which is in the
order of 41600 nT while Seine smt is relatively poorly magnetized. Data pre-
processing (temporal and diurnal corrections, IGRF correction, cross-over
check; etc.) has not yet been completed so magnetic contour anomalies will
not be presented in this report apart from some preliminary profiles (see
figure 18).
