Deep-Sea Research Part I: Oceanographic Research Papers: Radiocarbon-based ages and growth rates of cold-water bamboo corals in the South China Sea

HaozhuangWanga,XiaoliZhoua,HaowenDanga,LesWatlinga,ZhiminJianaaState Key Laboratory of Marine Geology, Tongji University, Shanghai, ChinaAbstract:Growth rates of cold-water bamboo corals are of crucial importance for establishing high-resolution chronology and reconstructing the development of these corals. However, due to the difficulty of sampling, their ages and growth rates as well as ecological indications are still fragmentary. In this study, radiocarbon analysis was performed on live-coll

GRL：Intermittent lobe reconnection under prolonged northward interplanetary magnetic field condition: Insights from cusp spot event observations

Xiong, Y.-Ta., Han, D.-Sa., Wang, Z.-Wa., Shi, Ra.,Feng, H.-Ta.aState Key Laboratory of Marine Geology, School of Ocean and Earth Science, Tongji University, Shanghai, ChinaAbstract:Previous studies have suggested that lobe reconnection under stable northward interplanetary magnetic field (IMF) conditions should be continuous. However, to what extent it can be considered as continuous is unknown. Auroral cusp spots have been considered a signature of lobe reconnection. Here, we show that during
