"RF Project 2264, Report No. 1"A profile of the total magnetic field was obtained along a 208 km track in Gerlache Strait, a tectonic depression off the west coast of the Antarctic Peninsula. There is no direct correlation between bottom topography and magnetic intensity. A very low magnetic gradient exists where the profile parallels the regional tectonic trend. Sharp anomalies occur where the profile crosses the tectonic trend.National Science Foundation Grant GA-529
