Han et al. (2025) Biogeochemical observations during the 2024 Yellow River Water-Sediment Regulation Scheme (WSRS) in Laizhou Bay and the Yellow River Estuary

Hydrographic (T, S, DO, pH), nutrient (NO₃⁻, NO₂⁻, NH₄⁺, PO₄³⁻, SiO₃²⁻), chlorophyll-a, suspended solids, and surface sediment TOC data collected during three cruises (June 16–20, July 11–18, and September 23–29, 2024) in Laizhou Bay and the Yellow River Estuary. These data support the findings reported in Han et al. (2025) "The Engineered River Pulse Paradox: A Dual-Action 'Sediment Brake' Regulates Hypoxia in an Anthropocene Estuary" published in Water Research
