1985 Total Magnetic Intensity (TMI) gridded data, Karonga Area, Northern Malawi, 9.69S-10.09S (2017, investigator Estella Atekwana)
The Total Magnetic Intensity (TMI) data for the Karonga area of Northern Malawi (IGRF not subtracted) between 9.69S-10.09S and 33.79E-34.09E. This processed airborne magnetic data set is a subset of the Southern African Development Community (SADC) airborne magnetic data set which covers the entire area of southern Africa. The data was acquired in 1984-1985, with a flight elevation of 120 m along NE–SW lines with spacing of 1 km. The tie lines were oriented NW–SE and spaced 10 km apart. The data was gridded at 95 m cell size using a minimum curvature algorithm. The data set is cited in Kolawole et al. (2017) in which it was used as part of the project called "Active deformation of Malawi Rift North Basin hinge zone modulated by reactivation of pre-existing Precambrian shear zone fabric". Funding was provided by NSF award EAR 1009988. The data file is in netCDF grid format. This data set is shared with other researchers for the purpose of research in Malawi only. The Council for Geosciences, South Africa has to be acknowledged as the source of the data. Detailed information on the acquisition parameters for this data (e.g. magnetometer sensor used, acquisition dates, geophysical contractor etc.) can be obtained from the The Council for Geosciences, South Africa.
