2013 IGRF-Corrected Total Magnetic Intensity (TMI) gridded data, Karonga Area, Northern Malawi, 9.69S-10.09S (2017, investigators Estella Atekwana, Jalf Salima, Leonard Kalindekafe)
IGRF-corrected Total Magnetic Intensity (TMI) data for the Karonga area of Northern Malawi between 9.69S-10.09S and 33.79E-34.09E. This processed airborne magnetic data set is a subset of a larger country-wide airborne magnetic data set acquired by the Geological Survey Department of Malawi in 2013. This data was acquired with a flight elevation of 80 m along NE–SW lines with spacing of 250 m. The tie lines were oriented NW–SE and spaced 5 km apart. The data was gridded at 50 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". The data file is in netCDF grid format. Funding was provided by NSF award EAR 1009988. This data set is shared with other researchers for the purpose of research in Malawi only. The government of Malawi has to be acknowledged as the source of the data, and all research findings have to be shared with the Geological Survey Department of Malawi. Detailed information on the acquisition parameters for this data (e.g. magnetometer sensor used, acquisition dates, geophysical contractor etc.) can be obtained from the Geological Survey Department of Malawi.
