Methane emissions from the upwelling area off Mauritania (NW Africa)
Coastal upwelling regions have been identified as sites of enhanced CH4 emissions to the atmosphere. The coastal upwelling area off Mauritania (NW Africa) is one of the most biologically productive regions of the world’s ocean but its CH4 emissions have not been quantified so far. More than 1000 measurements of atmospheric and dissolved CH4 in the surface layer in the upwelling area off Maurita...
متن کاملMicroallopatry Caused Strong Diversification in Buthus scorpions (Scorpiones: Buthidae) in the Atlas Mountains (NW Africa)
The immense biodiversity of the Atlas Mountains in North Africa might be the result of high rates of microallopatry caused by mountain barriers surpassing 4000 meters leading to patchy habitat distributions. We test the influence of geographic structures on the phylogenetic patterns among Buthus scorpions using mtDNA sequences. We sampled 91 individuals of the genus Buthus from 51 locations sca...

متن کاملGamma spectrometry for chronology of recent sediments Tracing human induced climate change in NW Africa
Gamma spectroscopy was used for determination of radionuclides in sediment cores from the continental shelf off NW Africa to provide age control of the sediment record used for a study of aridification of the Sahel zone. Pb, Ra and Cs were measured in the upper part of a gravity core and the associated multicorer and used for aligning these cores. This provided information about the amount of s...
