DNRA in intertidal sediments of the Yangtze Estuary

Journal of Geophysical Research: Biogeosciences, 2017
AbstractDissimilatory nitrate reduction to ammonium (DNRA) plays an important role in regulating the fate of reactive nitrogen in estuarine and coastal ecosystems. In this work, intertidal sediments of the Yangtze Estuary were collected in January and August 2015.

Annual cycle of hypoxia off the Changjiang (Yangtze River) Estuary

Marine Environmental Research, 2012
The annual cycle of hypoxia off the Changjiang Estuary, China, was assessed from data acquired during nine cruises in 2006-2007. Hypoxia began to develop in late spring and early summer, reached its maximum in August, weakened in the autumn and finally disappeared in the winter.

Management of Fishery Resources in Yangtze River Estuary

2009
We introduce the fish fauna composition and main commercial fishes in Yangtze River estuary. We also analyze the current situation of resources and environment in Yangtze River estuary as well as the influential factors. Finally, related countermeasures are put forward on how to protect and use the fishery resources in Yangtze River.

Pseudoalteromonas lipolytica sp. nov., isolated from the Yangtze River estuary

International Journal of Systematic and Evolutionary Microbiology, 2010
A strictly aerobic, Gram-negative, non-pigmented bacterial strain, designated LMEB 39T, was isolated from a seawater sample collected from the Yangtze River estuary near the East China Sea and was examined physiologically, chemotaxonomically and phylogenetically.

Natural radioactivity assessment of surface sediments in the Yangtze Estuary

Marine Pollution Bulletin, 2017
The activities of the natural radionuclides (238U, 232Th, 226Ra and 40K) of the surface sediments in the Yangtze Estuary were determined and used to evaluate radiation hazards in the study area. The of activities of 238U, 232Th, 226Ra and 40K ranges from 14.1 to 62.3, 26.1 to 71.9, 13.7 to 52.3, and 392 to 898Bqkg-1, respectively, which were comparable

A predictive model for salt intrusion in estuaries applied to the Yangtze estuary

Journal of Hydrology, 2015
Summary Understanding the way salinity distribution in an estuary reacts to external drivers (e.g., tide, fresh water discharge, dredging, etc.) is important for both water quality and water resources management in estuaries. The salinity distribution depends strongly on the geometry of an estuary, but also on the fresh water discharge that ...

[Study on nanoparticles in Yangtze Estuary].

Huan jing ke xue= Huanjing kexue, 2012
Filtration and cross-flow ultrafiltration (CFUF) was applied for the effective separation of NPs in the Yangtze Estuary. The physiochemical properties of NP were characterized, and their relationships with environmental factors were further studied in the present study.

Eco-Morphological Problems in the Yangtze Estuary and the Western Scheldt

Wetlands, 2011
This paper compares the Yangtze Estuary in China and the Western Scheldt Estuary in The Netherlands by their morphodynamic and ecological systems, their engineering works and estuarine management issues, and the major challenges in studying them. Physically speaking, the two estuaries are very different. The Yangtze Estuary is much larger and much more

Suspended Sediment Transport in the Offshore Near Yangtze Estuary

Journal of Hydrodynamics, 2008
Based on the Estuarine, Coastal and Ocean Modeling System with Sediments (ECOMSED) model, a 3-D hydrodynamic-transport numerical model was established for the offshore area near the Yangtze Estuary in the East China Sea. The hydrodynamic module was driven by tide and wind.

Numerical analysis of sediment deposition in Yangtze river estuary: Insight from conceptual estuary models

Applied Ocean Research, 2020
Abstract Since the construction of the Deepwater Navigation Channel Project in Yangtze River Estuary 1998, it is extremely imperative to clarify the sediment dynamics in Yangtze River Estuary to reduce deposition risks in the channel. However, the sediment deposition mechanism has not been well understood.
