Longitudinal distribution of salinity, temperature, turbidity and dissolved oxygen of surface waters in the Loire and Gironde estuaries. SEANOE. https://doi.org/10.17882/60629 Key physico-chemical parameters (salinity, temperature, turbidity and dissolved oxygen) were measured in surface water during longitudinal transects in the Loire and Gironde estuaries in summers 2017 and 2018. This objective of this work was to determine the distribution of the dissolved oxygen and to detect potential severe desoxygenation. The transects were scheduled in order to begin the measurements at high tide from a site located upstream of an area where severe deoxygenation have been already been reported. Then, the transect was realised by sailing at low speed downstream with a multiparameter probe SAMBAT, maintained at 0.5 m below the surface, that collected a measurement every 2 minutes. This work has received funding support of the AEAG (Agence de l’Eau Adour Garonne) and the AFB (Agence Française pour la ; Biodiversité).

The measured parameters are temperature (−-5 to +35°C; ± < 1%), salinity (range 0.1 -42; ± < 5%), turbidity (Turner Designs CYCLOPS-7; 0 - 3000 NTU; ± < 5%), dissolved oxygen (0 - 20 mg L-1;  ±0.1 mg L-1) and fluorescence (Turner Designs CYCLOPS-70 - 50 µg L-1; ± < 5%).
