英文摘要: Based on two multidisciplinary investigations conducted in summer and winter 2015, the distribution of dissolved oxygen (DO) and the associated seasonal variations off the Changjiang River Estuary (CRE) were studied. The DO content was high in winter, ranging from 6.81–10.29 mg/L, and the distribution was mainly controlled by temperature and salinity. The DO concentration was 1.92–9.67 mg/L in summer, and a hypoxic zone (DO < 3 mg/L) covered 14,800 km2, which was mainly controlled by stratification and organic matter decomposition. The hypoxic zone exhibited a “dual-core” structure and the differences in the biochemical and physical processes between the southern and northern regions were compared: the northern region exhibited stronger pycnocline intensity; while larger biomass and higher TOC as well as TN contents were observed in the southern region. Hypoxia in the northern region might be mainly dominated by stratification, while that in the southern region was mainly associated with organic matter decomposition. © 2017 Elsevier Ltd Citation statistics:
