Imaggeo on Mondays: Strombolian eruption 

Jonas Kuhn, a researcher at Heidelberg University , took the photograph during a field campaign at Stromboli volcano in Italy. The objective of this campaign was to gather data from different gaseous compounds of the volcanic plume. Via emission fluxes of volcanic gases (e.g. SO2, CO2, halogen compounds…) or the ratio of emitted gases, one can retrieve information about the interior of the volcano and magma dynamics. Volcanic gas measurements can therefore contribute to better [...]

The trek to Patagonia in 1930 had its paleontological objectives, for sure, but it also had singularly personal ones for George Gaylord Simpson (1902-1984).  In that year, though a young 28 years of age, Simpson already was associate curator of vertebrate paleontology at the American Museum of Natural History and a leading expert on Mesozoic mammals.  He was at the beginning of a brilliant career, one that would transform paleontology.  By the middle of the 20th century, he would [...]
