Effects of a storm on the transformation and export of phosphorus through a subtropical river-turbid estuary continuum revealed by continuous observation

Zhang MZ, Krom MD, Lin JJ, Cheng P, Chen NW*Journal of Geophysical Research: Biogeoscienceshttps://doi.org/10.1029/2022JG006786Published: 8 August 2022AbstractMajor storms, which are increasing in frequency due to climate change, flush pollutant nutrients, including phosphorus (P), from river catchments through estuaries to the coast. Changes in P speciation alter the potential for P removal in...

Simultaneous observations revealed the non-steady state effects of a tropical storm on the export of particles and inorganic nitrogen through a river-estuary continuum
