Summary

Story summary

Prof. Xiao Kai's team at the Yantai Institute of Coastal Zone Research found that sandy beaches and mudflats influence nutrient fluxes in intertidal groundwater.
The findings published in the Journal of Hydrology show distinct nutrient distributions between fine-grained and coarse-grained sediments.
Sandy beaches discharge higher dissolved nutrients and carbon, which may worsen nearshore eutrophication and acidification, prompting researchers to propose sediment-structure management to enhance purification of tidal flats.
