Raw lake floor horizon data and bathymetry for Lake Malawi (Nyasa), East Africa (within Malawi, Tanzania, Mozambique)

This ASCII CSV file provides raw lake floor horizon and bathymetry data interpreted from legacy multichannel and single-channel seismic reflection data from as early as 1985, and not from hydrographic surveys. Accordingly there is considerable error associated with lake floor horizon picks. Primary data quality varied widely. Positioning information is derived from autonomous GPS data or from Transit Satellite data collected during seismic acquisition, and positioning quality varies widely. See the Lyons et a., 2011 for specific information on primary data. The file contains six columns: UTM X (meters), UTM Y (meters), latitude (degrees), Longitude (degrees), Lake Floor Elevation above sea level (m), Depth below lake surface (meters). The UTM values are in UTM zone 36 S.
