Oxygen budget dynamics estuaries
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 … WebA case study on the oxygen budget in the freshwater part of the Elbe estuary. V: Distribution of different ammonia-oxidizing bacteria in the river Elbe downstream of Hamburg at low …

Weboxygenated seawater into the estuary, also alters the oxygen budget of estuaries (Lin et al. 2006; Hagy and Murrell 2007). In this paper, we investigate oxygen depletion that ... which is set by the sediment dynamics of turbidity zones - governs the depletion of DO. Observational Background The Ems-Dollard estuary, located on the border of the ... 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.
WebNov 30, 2024 · Especially in the warmer months with a lower oxygen saturation and higher biological activity, the oxygen content can reach critical thresholds in estuaries like the upper Elbe estuary. Many studies have dealt with the nutrient fluxes that occur during a resuspension event. WebGED has developed a process-based approach to hypoxia research on Pensacola Bay as a model Gulf of Mexico estuary. We selected Pensacola Bay because, like many Gulf coast estuaries, it is shallow, microtidal, and experiences seasonal hypoxia. We also have an historical database from EMAP-related activities and other research programs resulting …
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 … WebJan 4, 2024 · This offshore change can also impact biogeochemical pathways in estuaries. Advection of low dissolved oxygen water from offshore was observed by Fujiwara ( 2002) and Brown and Nelson ( 2015) and is a central component of …
WebIn many estuaries, oxygen depletion is tied to the inputs of organic matter caused by effluent, industry, or natural causes (Hagy et al. 2004; Dai et al. 2006; Fang and Lin 2002; …
