Sediment shifts reshape microbial life and carbon cycles in Yellow River estuaries
Sediment shifts in the Yellow River estuary are rewriting the rules of microbial life and carbon storage below the seafloor. Comparing cores from the river's abandoned and present channels reveals that where sediment accumulates, reactive iron pools persist, sustaining iron-reducing microbes and fostering a more connected subsurface community. Where sediment supply stops, methane-related functional potential rises as iron declines. This is empirical, measurable evidence that sedimentary regimes govern benthic carbon-cycling potential.
Sediment Records Reveal 250 Years of Climate and Human Impact
Two hundred fifty years of sediment in the South China Sea and Taiwan Strait tell a clear story: climate drove the past, but humans now steer the system. Clay minerals and grain-size records from cores D0 and Y22 reveal intensified monsoon runoff before the 1920s, then a sharp divergence after the 1950s. Declining terrigenous input and coarser sediments point not to natural variability, but to regional dam and engineering projects. This is measurable, human-driven change.
