Marine hydrogen production systems deployed on ships and floating platforms are inevitably subjected to complex multi-degree-of-freedom motions induced by waves and wind, which may influence electrolyzer performance. However, experimental investigations under realistic marine motion conditions remain limited. In this study, a laboratory-scale alkaline water electrolyzer was installed on a six-degree-of-freedom (6-DOF) motion p...

Human-driven soil erosion is a signal of the widely debated “Anthropocene”. There is widespread controversy regarding the time consistency and time transgression of human-driven soil erosion in the Late Holocene. In this study, three well-dated cores, B10, B14 and W20 from west to east, spanning the past 4–6 ka from the Pearl River Estuary (PRE) shelf, southern China, were selected for elemental tests. Principal component anal...
