Tidal exchange between a freshwater tidal marsh and an impacted estuary: the Scheldt estuary, Belgium Vrije Universiteit Brussel

Feeding preferences of estuarine mysids Neomysis integer and Rhopalophthalmus tartessicus in a temperate estuary (Guadalquivir Estuary, SW Spain) Universiteit Gent
Impact of salinity gradient, water pollution and land use types on greenhouse gas emissions from an urbanized estuary Universiteit Gent
Estuaries have been recognized as one of the major sources of greenhouse gases (GHGs) in aquatic systems; yet we still lack insights into the impact of both anthropogenic and natural factors on the dynamics of GHG emissions. Here, we assessed the spatiotemporal dynamics and underlying drivers of the GHG emissions from the Scheldt Estuary with a focus on the effects of salinity gradient, water pollution, and land use types, together with their ...
Carbon and hydrogen isotope signatures of dissolved methane in the Scheldt Estuary Vlaams Instituut voor de Zee Vrije Universiteit Brussel
We collected water samples from the Scheldt estuary during December 2015 and November 2016 for methane (CH4) concentration and isotopic composition (δ13C and δD values) analyses, to investigate the origin of the excess dissolved CH4, which is a common feature in estuaries. The Scheldt estuary is a eutrophic, heterotrophic tidal estuary, located at the border between Belgium and the Netherlands. The gas chromatography and mass spectrometry ...
The effect of a dam construction on subtidal nematode communities in the Ba Lai Estuary, Vietnam Universiteit Gent
Nematode communities and relevant environmental variables were investigated to assess how the presence of a dam affects the Ba Lai estuary benthic ecosystem, in comparison to the adjacent dam-free estuary Ham Luong. Both estuaries are part of the Mekong delta system in Vietnam. This study has shown that the dam's construction had an effect on the biochemical components of the Ba Lai estuary, as observed by the local increase in total suspended ...
Unravelling spatiotemporal N2O dynamics in an urbanized estuary system using natural abundance isotopes Universiteit Gent
Estuaries are strong sources of N2O to the atmosphere; yet we still lack insights into the impact of their biogeochemical dynamics on the emissions of this powerful greenhouse gas. Here, we investigated the spatiotemporal dynamics of the N cycle in an estuary with a focus on the emission mechanisms and pathways of N2O. By coupling N2O isotopocule analysis and substrate NO3- isotope analysis, we found that nutrient availability, oxygen level, ...
Spatial distribution and general population characteristics of mysid shrimps in the Westerschelde estuary (SW Netherlands) Vlaams Instituut voor de Zee Universiteit Gent
The distribution and general population characteristics of five mysid shrimps were investigated in theperiod 20032005 in the Westerschelde estuary, a tidal temperate estuary situated along the DutchBelgian border. Multivariate analyses revealed that salinity predominantly governs the spatial distribution of Neomysis integer, Gastrosaccus spinifer, Schistomysis kervillei and Schistomysis spiritus while temperature, and to a lesser extent ...
Origin and partitioning of mercury in the polluted Scheldt Estuary and adjacent coastal zone Vrije Universiteit Brussel
Estuaries and coastal zones are areas with complex biogeochemical and hydrological cycles and are generally facing intense
pollution due to anthropogenic activities. An emblematic example is the Scheldt Estuary which ends up in the North Sea
and has been historically heavily contaminated by multiple pollutants, including mercury (Hg). We report here Hg species
and their levels in surface waters of the Scheldt Estuary and the ...

Carbon biogeochemistry of the Betsiboka estuary (north-western Madagascar) Vrije Universiteit Brussel
Madagascar's largest estuary (Betsiboka) was sampled along the salinity gradient during the dry season to document the distribution and sources of particulate and dissolved organic carbon (POC, DOC) as well as dissolved inorganic carbon (DIC). The Betsiboka was characterized by a relatively high suspended matter load, and in line with this, low DOC/POC ratios (not, vert, similar0.4-2.5). The partial pressure of CO2 (pCO2) was generally above ...
