Nearshore archipelagic waters are crucial zones for offshore wind power development.However,re-search on the transport processes of suspended sediment in archipelago environments remains limited,which re-stricts a deeper understanding of regional material and energy movement mechanisms.Based on field observations of tidal currents and suspended sediment in the waters around the Fujian Nanri Floating Wind Farm,this study an-alyzed tidal dynamics,distribution patterns of suspended sediment under the topographical constraints of the Nanri Islands,and identified the sources and pathways of sediment transport over a tidal cycle.The results show that the distribution of suspended sediment concentration near the Nanri Archipelago varies over space and time,with tidal transport pathways involving both onshore and offshore movements.Suspended sediments are mainly transported onshore via the coastal zone north of the Nanri Waterway and the Xinghua Waterway,while offshore transport oc-curs through the Nanri Waterway.Onshore transport mainly comes from offshore areas,whereas offshore transport originates from Xinghua Bay and nearby regions,with some areas experiencing localized resuspension.These findings provide a scientific foundation for engineering operations and maintenance of wind-fishery integrated floating wind power projects,as well as for marine area management.
