Divergent Blue Carbon Trajectories in the Yellow River Delta Post‐1976 Diversion: Hydrological Stability and Human Disturbance Contrasts Revealed by Multi‐Source Remote Sensing (1984–2023)

Land Degradation &Development, EarlyView.
ABSTRACT Coastal wetlands are critical blue carbon sinks, yet their spatiotemporal dynamics under environmental change remain insufficiently quantified. Taking the Yellow River Delta (YRD) as a natural laboratory, this study synthesizes multi‐source remote sensing data, including optical and radar imagery spanning from 1984 to 2023, to explore the ...

Refining techniques for high‐frequency monitoring of chlorophyll a fluorescence in estuarine systems

Limnology and Oceanography: Methods, EarlyView.
Abstract Concentrations of the photosynthetic pigment chlorophyll a are commonly used as a proxy for phytoplankton biomass in aquatic systems. Traditional methods for extracting chlorophyll a in discrete samples limit measurement frequency, while in situ sensor technology provides high frequency chlorophyll a fluorescence measurements at a more ...

A simplified two‐station approach for modeling metabolism in dam tailwaters subject to diel flow variation

Limnology and Oceanography: Methods, EarlyView.
Abstract Tailwaters are ubiquitous and highly managed ecosystems whose food webs often rely disproportionately on autochthonous energy. In situ continuous dissolved oxygen data are increasingly being used to estimate gross primary productivity and ecosystem respiration in rivers, but this approach is complicated in tailwaters, where upriver ...

Modeling the tidal and sub-tidal hydrodynamics in a shallow, micro-tidal estuary

Ocean Modelling, 2015
Abstract The three-dimensional hydrodynamics of Galveston Bay were simulated in two periods of several month duration. The physical setting of Galveston Bay is described by synthesis of long-term observations. Several processes in addition to tidal hydrodynamics and baroclinic circulation processes contribute substantially to the observed variability

Tidal Bores

2013
A tidal bore is a series of waves propagating upstream in the river mouth as the tide turns to rising. It forms during the spring tide conditions with a tidal range in excess of 4.5–6 m in a narrow funneled estuary with low freshwater levels. The presence of a tidal bore indicates some macrotidal conditions associated with an asymmetrical tide. Two key
