MATLAB Recipes for Earth Sciences, 5th Edition

The 5th edition of MATLAB Recipes for Earth Sciences now has a book cover and can already be pre-ordered on the publisher’s webpage. The picture on the top is a 3D display of a filtered SRTM elevation data set of the Baringo area in Kenya, showing fault escarpments and lake basins. The function surfl has been used to generate a shaded-relief map with simulated lighting, contour3 to create white elevation contours and the demcmap colormap from the Mapping Toolbox.

Dip and Dip Direction using Smartphones

The following exercise is intended to help to understand the measurement of the orientation of linear and planar structures in the field, using the magnetometer and the gyroscope of the smartphone. We will carry out a large number of repeated measurement, not possible with a traditional compass in a reasonable time. These repeated measurements will be statistically evaluated and interpreted with regard to their accuracy and precision.

Fifth Chew Bahir Drilling Project Workshop at Neanderthal Museum

Next week scientists from the Chew Bahir project will meet at the Neanderthal Museum near Düsseldorf to discuss the latest results of the 290 m long ICDP cores from S Ethiopia. The project, as part of the international Hominin Sites and Paleolaces Drilling Projects (HSPDP), tries to fill gaps in the environmental history of eastern Africa, the habitat of early human ancestry. Within the framework of the project, two ~290 m long cores were collected in the Chew Bahir Basin in Southern Ethiopia including the last ~550,000 year history of environmental change in the southern Ethiopian rift were some of the oldest fossils of our own species were discovered. The latest results from analyzing these cores will be discussed during the workshop.
