Heavy precipitation-induced Yangtze River runoff greatly regulates heterotrophic prokaryotes production and induces P-limited growth in the northern East China Sea

To elucidate the impact of Yangtze River Diluted Water (YRDW) on Heterotrophic prokaryotes production (HPP) and growth-limiting resources, we conducted comprehensive microbial oceanographic measurements from 2020 to 2022, integrating satellite image analysis and optical property measurements of dissolved organic carbon (DOC) in the northern East China Sea (31.5-32.5°N, 124.5-127.1°E). Seawater samples were collected on board. Limiting resources assay were conducted on board. DOC, fluorescent dissolved organic matter, prokaryotes abundance (PA), heterotrophic prokaryotes production (HPP) and primary production (PP) of seawater were analyzed.
