GSF: Proterozoic to phanerozoic case studies of laser ablation microanalysis for microbial carbonate U–Pb geochronology

Yuxiang Jianga, Simon V. Hohla, Xiangtong Huanga, Shouye YangaaState Key Laboratory of Marine Geology, Tongji University, Shanghai, 200092, ChinaAbstract：Some of the earliest bio-sedimentary records of life on Earth are represented by microbial carbonates, which are also critical geochemical archives of ancient seawater chemistry and the environmental circumstances in which they precipitated. Reconstructing paleo-microbial environments on Earth and potentially other planets requires precise dete

JGR-Oceans:Enhanced Mixing at the Edges of Mesoscale Eddies Observed From High-Resolution Seismic Data in the Western Arctic Ocean

Shun Yang1,2, Haibin Song1,2, *, Bernard Coakley3, Kun Zhang1,21School of Ocean and Earth Science, Tongji University, Shanghai, China2State Key Laboratory of Marine Geology, Tongji University, Shanghai, China3Geophysical Institute, University of Alaska Fairbanks, Fairbanks, AK, USAAbstractIn recent years, the Arctic Ocean has experienced a dramatic decrease in sea ice cover, leading to enhanced turbulent mixing and eddy activity. Due to the scarcity of high-resolution observations, our understan

GPC：Precession control of interglacial winter monsoon intensity over tropical East Asia

Enqing Huang, Shihe Wang, Sihua Wei, Zijie Yuan, Jun TianState Key Laboratory of Marine Geology, Tongji University, 200092 Shanghai, ChinaAbstract：The history of the East Asia winter monsoon (EAWM) and its forcing mechanisms remain elusive due to conflicting reconstructions. In this study, we attempt to quantify changes in interglacial winter monsoon intensity over tropical East Asia, based on reconstructions from the southern South China Sea (SCS) and model outputs from transient simulations (T

IEEE TGRS: Broadband Acoustic Impedance Building via the Fusion of Sparsely Promoted Reflectivity and Background Acoustic Impedance

Ting Leia, Huazhong Wanga, Bo FengaaSchool of Ocean and Earth Science, Tongji University, Shanghai 200092, ChinaAbstract：Geophysical exploration is developing from qualitative seismic imaging to quantitative imaging, and broadband acoustic impedance is the core. Directly estimating broadband impedance using Full-Waveform Inversion is a strong nonlinear problem. It is difficult to obtain a reliable result in practice. We proposed an alternative way: Estimate background velocity, density and broad
