Vertical distributions of temperature, salinity, dissolved oxygen concentrations and saturations, Chl-a, turbidity and pH in the water column of the continental shelf off the Gironde (North East Atlantic, France)
The aim of this work was to document the seasonal and inter-annual dynamic of dissolved oxygen and ancillary data (T, S, Chl-a, turbidity, pH) along a cross-shelf transect off the Gironde estuary. This work has been motivated by recent simulations that suggest the occurrence of seasonal bottom deoxygenations in this River-dominated Ocean Margin (Riomar); but unfortunately there were no data sets to test this hypothesis until now. Profiles of temperature, salinity and dissolved oxygen were performed in the water column of the West Gironde Mud Patch off the Gironde estuary (from 45°46.383’N – 1°28.925’W to 45°35.524’N - 1°50.689’W) during seven cruises on the R/V Côte de la Manche (doi: 10.18142/284 ; 10.17600/18000861) between 2016 and 2021 (October 2016, August 2017, January 2018, April 2018, July 2019, April 2021, October 2021). Turbidity was measured in January and April 2018, July 2019 and October 2021, Chl-a in October 2016, August 2017, January 2018, April 2018 and July 2019 and pH in October 2021. This dataset had permitted to validate the occurrence of bottom deoxygenations when the water column is stratified.

- Statement
- The measurements were performed using a SeaBird SBE-19plus, a Wimo Plus multiparameter probe (NKE Instrumentation) and autonomous sensors (STPS, SDOT and STBD, NKE Instrumentation). The measured parameters were temperature (SeaBird SBE-19plus: -5 to +35°C, <±1%; STPS: -5 to +35°C, <± 1% ; Wimo Plus: -2 to +35°C, ±0.02°C), salinity (SeaBird SBE-19plus: 2 – 42 , <±1% ; STPS: 2 - 42, <±1% ; Wimo Plus: 2 – 42, ±0.1%), dissolved oxygen (SDOT: 0 – 500µM, 0 – 150%, <±5% ; Wimo Plus: 0 – 700µM, 0 – 250%, <±1%), turbidity (STBD: 0 – 2000 NTU, <±5%, Wimo Plus: 0 – 4000 NTU, <±5%), Chl-a (SeaBird SBE-19plus: 0.03 – 75 µg/L, <±5%) and pH (Wimo Plus: 0 – 14, ±0.1). Turbidity sensors were intercalibrated using formazin, allowing to provide turbidity data in Formazin Nephelometric Units (FNU). Missing data are replaced by the value “-9999”.
