δ18O and δ2H measured in tap waters from France and neighbouring countries
收藏资源简介：
The database contains <strong>δ<sup>18</sup>O and δ<sup>2</sup>H in tap waters from France and neighbouring countries</strong> (original data:Daux et al., 2021), in precipitation, tap water or river water in Belgium, Deutschland, Great Britain, Italy, Netherland, Spain and Switzerland (already published data; references below), and <strong>modelled in precipitation by ECHAM6-wiso</strong> (original data: Daux et al., 2021). <strong>Analyses:</strong> Performed with Picarro L2130-I wavelength-scanned cavity ring-down spectroscopy instrument (Picarro Inc, Sunnyvale, CA, USA) Sample values reported using the <strong>δ</strong> notation where <strong>δ</strong> = R<sub>sample</sub>/R<sub>standard</sub> -1, R being <sup>18</sup>O/<sup>16</sup>O or <sup>2</sup>H/<sup>1</sup>H Reference : VSMOW water standard Analytical precision: 0.20‰ (1s) for oxygen and 0.7 ‰ (1s) for hydrogen
