Purpose | |
Abstract | Cruise M123 dealt with investigating the dynamics and control of climate change in South Africa during late quaternary. The two Kongsberg Multibeam bathymetry systems were used alongside the EM710 shallow/mid water system. Each system was used to acquire data within respective operational water depths which allowed the best possible resolution data to be collected along transects and during transit between working areas. |
