The increased interest in the potential shale gas extraction within the Karoo basin is raising concerns regarding the potential impact it may have on this fragile environment. In order to be in the possible position to moderate any negative effects associated with possible hydraulic fracturing, a scientifically thorough base-line of this region will need to be obtained. Since our current geophys ... More

Poor choice of colourmaps within visualisation can lead to the creation of visual artifacts, which creates false interpretation of the visualisation, either by seeing edges that do not exist or by obscuring edges that do. The use of perceptual colourmaps, where each change in colour is perceived as smooth can greatly enhance the ease of interpretation of a visualisation by removing ambiguity. In ... More

The main Karoo basin sedimentary sequence covers an approximate area of 700 000km2, and attains a thickness of more than 5Km. The emplacement of the Karoo Large Igneous Province (LIP) through dolerite dykes and sills, and lava flows (ca 183Ma) led to extensive devolitilization, metasomatism, and out-gassing of approximately 2000Gt of carbon dioxide and methane into the atmosphere.

The existing link budget equation estimates the number of return photons for given conditions and LLR system parameters. This equation is one of the essential mathematical tools that can be considered when developing an integrated system and m ... More
