Joven Mandair has accomplished his bachelor thesis on Sr isotope measures in corals and seawater


Joven Mandair conducted his bachelor thesis on the use of Sr isotopes as a tracer of riverine and aeolian dust to the Atlantic Ocean. He analysed a 150 year long coral sequence from Cuba, but within the reproducibility of ±20 ppm no significant 87Sr/86Sr ratio variations could be found. The results perfectly match present day seawater Sr isotope composition, for which, however, a minor but significant deviation from the global mean was found near the Gulf of Cadiz and in the surface waters. Likely a first evidence of Sr weathering from Sahara dust. We congratulate Joven for his great work and implication and in particular for his outstanding thesis colloquium. We wish you all the best for the future.
