EPSL：Radiogenic and stable Sr isotopes constrain weathering processes in rapidly eroding Taiwan catchments

Ni Sua， Shouye Yanga， Kai Denga， Yuan-Pin Changb， Juan Xua， Zhouyang WuaaState Key Laboratory of Marine Geology, Tongji University, Shanghai 200092, ChinabInstitute of Marine Geology and Chemistry, National Sun Yat-sen University, Kaohsiung, TaiwanAbstractSmall mountainous rivers (SMRs) in subtropical Taiwan supply a disproportionately large quantities of suspended and dissolved flux to the ocean due to extraordinarily high denudation rates in the world. We present major elements, 87Sr/86Sr, and

JGR-Solid Earth: Reflection Full Waveform Inversion With Second-Order Optimization Using the Adjoint-State Method

Tengfei Wang , Jiubing Cheng , and Jianhua Geng State Key Laboratory of Marine Geology, School of Ocean and Earth Science, Tongji University, Shanghai, ChinaAbstract: In controlled-source seismology, the standard full waveform inversion (FWI) cant reliably recover the macrovelocity structure in the deep part, if the surface seismic data lack of ultra-long offsets and very low frequencies. Reformulating the FWI for pre-critical reflections based on model scale separation leads to reflection wave

The Innovation： Low-latitude forcing: A new insight into paleo-climate changes

PinxianWang11 State Key Laboratory of Marine Geology, Tongji University, Shanghai 200092, ChinaMain textThe origin of glacial cycles is central to paleo-climate research. A major breakthrough of Earth science in the 20th century was the discovery of orbital forcing of the glacial cycles, known as the Milankovitch theory. The periodicity of the glacial cycles over the last million years was successfully explained by the variations of June solar insolation at 65°N. In responding to the changes in
