Web15 hours ago · Hypoxia, or low dissolved oxygen (DO) is a common outcome of excess nitrogen and phosphorus delivered to coastal waterbodies. Shallow and highly productive estuaries are particularly susceptible to diel-cycling hypoxia, which can exhibit DO excursions between anoxia (DO ≤1 mg L −1) and supersaturated concentrations within a …

WebThe dissolved oxygen budget in the upper Delaware Estuary between 1970 and 2014 was inferred from oxygen concentration measurements using a box model approach. The region was found to be a net biogeochemical sink of oxygen, with net oxygen consumption greater in the tidal fresh portion than in the oligohaline portion. Net oxygen consumption … WebSep 28, 2024 · Abstract. The Pearl River estuary (PRE) frequently experiences low-oxygen conditions in summer, with large-extent low-oxygen events and a long-term deoxygenation trend being reported recently. In this study, we provide a synthesis of the spatiotemporal patterns and incidence of different low-oxygen levels in the PRE based on the in situ …
WebCarbon dynamics of salt marsh-dominated estuaries have fascinated coastal ecosystem ecologists for more than half a century because of their tremendously high rates of primary production, their support for commercial fisheries, and their disproportionately large contribution to the global carbon budget relative to their size (Bauer et al. 2013 ). WebNov 14, 2024 · We compute monthly NEP over more than 12 years by constructing the dissolved oxygen budget for the estuary from monthly snapshot oxygen survey data (i.e., collected once per month). High-frequency observations of oxygen in similar subtropical estuaries were used to quantify the error associated with the snapshot monthly sampling.
