Profile location data for a 2-D Electrical Resistivity Tomography (ERT) survey, Karonga, Northern Malawi Rift (2015, investigators Estella Atekwana, Daniel Lao-Davila, Folarin Kolawole)

This data set contains shapefiles showing the location of the 2-D electrical resistivity tomography profiles acquired in July 2015 in the Karonga area of northern Malawi Rift. The ERT profile data was collected using a dipole–dipole array with an Iris Syscal Pro 10-channel resistivity meter. There were 72 electrodes with 10 m electrode spacing. Profile 1 is a NNW-SSE profile along the trend of the surface ruptures. Profiles 2 and 3 are roughly E-W profiles oriented perpendicular to and across the trend of the surface ruptures. Profile 1 is 1070 m long, and Profiles 2 and 3 are 710 m long. The data files are in shapefile format. They were generated as part of the projects called Integrated studies of early stages of continental extension: From incipient (Okavango) to young (Malawi) rifts, and IRES: Research Opportunities in Continental Rift Initiation for U.S. Undergraduate Geoscience Students in Malawi. Funding was provided by NSF awards EAR 1009988 and OISE 1358150. The 2015 Malawi data acquisition team included five 2015 International Research Experience for Students (IRES) participants: B. Clappe, C. Hull, T. Johnson, V. Nyalugwe, and S. Dawson.
