Research Article of IES postdoc Yi-Wei Liu Published in Nature Communication

Dr. Yi-Wei Liu and her international research team first apply boron isotopes, stable carbon and oxygen isotopes, and particulate inorganic carbon and particulate organic carbon content to investigate the impact from ocean acidification to coccolithophore species Ochrosphaera neapolitana. Their results suggest that this species will maintain a constant pH at the calcification site, regardless of CO2-induced changes in pH of the surrounding seawater. The algae utilize carbon from a single internal dissolved inorganic carbon (DIC) pool for both calcification and photosynthesis, and that a greater proportion of dissolved CO2 relative to HCO3− enters the internal DIC pool under acidified conditions. These two observations may explain how O. neapolitana continues calcifying and photosynthesizing at a constant rate under different atmospheric-pCO2 conditions. The research also help us better understand the mechanisms behind the highly varied calcification and growth responses from marine calcifying organisms to ocean acidification.

IES High-pressure Mineral Physics Laboratory Research Published in PNAS (Proceedings of the National Academy of Sciences, USA)

Dr. Wen-Pin Hsieh of the IES high-pressure mineral physics laboratory has combined ultrafast optics with diamond cell techniques to measure the thermal conductivity of ferropericlase at high pressures. His team found that the thermal conductivity of iron-rich ferropericlase drops significantly across spin transition of iron, resulting in an enhanced iron substitution effect in the low-spin iron-rich ferropericlase. Combined with prior results and data modeling, they demonstrated that iron plays critical roles in affecting the thermal conductivity, thermo-chemical structures, cooling rate, and geodynamics in the lower mantle. These results further help better understand the thermal history of ultra-low velocity zones at the bottom of the mantle: if these regions are hot and enriched in iron, their exceptionally low thermal conductivity may delay their cooling and keep them substantially hotter than their surroundings. The international research team includes Drs. Wen-Pin Hsieh and Frédéric Deschamps of IES, Prof. Jung-Fu Lin of University of Texas at Austin, and Dr. Takuo Okuchi of Okayama University.

IES Director Academician Sun-Lin Chung was elected 2018 TWAS Fellow

The World Academy of Sciences (TWAS) announced the election of three Academia Sinica Academicians among its 2018 list of 55 new TWAS Fellows on January 26 in Trieste, Italy. IES Director Academician Sun-Lin Chung was elected to the area of Astronomy, Space and Earth Sciences among only 5 new TWAS Fellows. Academician Chung has made significant contribution to our understanding of continental tectonics and magma generation based on his outstanding studies in High Asia (from Tibet to Iran) and neighboring regions. He has also received the TWAS Prize in Earth Sciences in 2014. [Details]
