Tracing the Persistence and Role of Deep‐Sea Iron Sources in the Pacific Ocean Over the Last 23 Million Years

Yongzhi Chu, Xiaohu Li, Ruifang C. Xie, Tim M. Conway et autres

Abstract Iron (Fe) plays a critical role in marine productivity and the global carbon cycle. The relative contribution of different Fe sources such as atmospheric aerosols, sediment dissolution, and submarine hydrothermalism influences the distribution and biogeochemical cycling of Fe in the ocean. …

Grain-Size Characteristics and Transport Trends of Surficial Sediments at Mushao Beach, Sanmen Bay: Insights from Random Forest and K-means Clustering

Yi Zhang, Xibin Han, Zhenyi Cao, Zhihua Zheng et autres

This study examines 72 surficial sediment samples collected from Mushao Beach in Sanmen Bay (Zhejiang Province, China) to investigate grain-size characteristics and sediment transport trends in a tidal-flat environment. The spatial distribution of particle size and the direction of net sediment transport …

In-situ geochemistry of fish teeth in REE-rich mud: Indicating missing REE-bearing mineral phases for mass balance

Yang Chen, Huan Zhang, Yanhui Dong, Tianyi Wang et autres

Due to the high concentration of rare earth elements (REE) and the tremendous volume, the deep sea REE-rich mud has gained significant attention as a potential resource. The bioapatites, mainly fossil fish teeth and bones, were thought to be the main host …

Iterative Maximum Ratio Combining Detector for Satellite Multiple-Input Multiple-Output/Orthogonal Time–Frequency Space Systems Based on Soft-Symbol Interference Cancelation

Meng Sun, Qi Zhang, Haipeng Yao, Ran Gao et autres

Orthogonal time–frequency space (OTFS) modulation combined with massive multiple-input multiple-output (MIMO) can simultaneously address the problems caused by multipath delay, the Doppler effect, and channel fading. To mitigate inter-subcarrier and inter-symbol interference in satellite–terrestrial MIMO-OTFS systems, an iterative maximum ratio combining detection …
