Moreover, in ordrer to evaluate how topsoil can influence the quality of surface water, lake water was sampled monthly at the same time that soil was sampled. The N-NO3 concentration is measured in water samples collected in triplicate in two lakes (Cimalegna and Bowditch). The ongoing studies aimed at investigating how the meteorological variables affect the biogeochemistry of seasonally snow covered areas, with a special focus on the effect of the snow cover duration on soil and water C and N dynamics during the growing season.","keywords":[{"label":"alpine","uri":null},{"label":"alpine tundra","uri":null},{"label":"carbon","uri":null},{"label":"lakes","uri":null},{"label":"nitrogen","uri":null},{"label":"soil chemistry","uri":null},{"label":"water chemistry","uri":null}],"inspire":null,"dateRange":{"from":"2008-09-30","to":null},"language":"English","relatedSite":[{"type":"site","title":"Istituto Scientifico Angelo Mosso (MOSSO) - Italy","id":{"prefix":"https:\/\/deims.org\/","suffix":"17210eba-d832-4759-89fa-9ff127cbdf6e"},"changed":"2025-01-07T11:14:56+0100"}]},"contact":{"corresponding":[{"type":"person","name":"Michele Freppaz","email":"michele.freppaz@unito.it","orcid":null}],"creator":[{"type":"person","name":"Michele Freppaz","email":"michele.freppaz@unito.it","orcid":null}],"metadataProvider":[{"type":"person","name":"Michele Freppaz","email":"michele.freppaz@unito.it","orcid":null}]},"observations":{"parameters":null,"speciesGroups":null},"geographic":[{"boundaries":"POLYGON ((7.86836 45.87656, 7.8911 45.87656, 7.8911 45.86617, 7.86836 45.86617, 7.86836 45.87656))","abstract":"Istituto Scientifico Angelo Mosso (MOSSO): LTER_EU_IT_076:Col d\u0027Olen, water chemistry (KCl extractable NO3)","elevation":{"min":"2500","max":"2900","unit":"msl"}}],"onlineDistribution":{"dataPolicyUrl":null,"doi":null,"onlineLocation":[{"function":"url","url":{"title":"Lakes N-NO3","value":"https:\/\/b2share.fz-juelich.de\/records\/efbfb51283584e0ab7693a94dbc50876"},"email":null}]},"legal":{"accessUse":[{"label":"Free for access and use upon request","uri":null}],"rights":["Co-authorship on publications resulting from use of the dataset","Formal acknowledgement of the dataset providers","The opportunity to collaborate on the project using the dataset","Reprints of articles using the dataset must be provided to the data provider"],"legalAct":null,"citation":null},"method":{"instrumentation":["Hitachi Spectrophotometer U-2000"],"qualityAssurance":null,"methodUrl":null,"methodDescription":["Concentrations of nitrate in water samples were determined spectrophotometrically by the Greiss reaction as described by Mulvaney (1996) and modified by Cucu et al.(2014).","Spectrophotometer (U-2000, Hitachi, Tokyo, Japan)"],"samplingTimeUnit":{"label":"_unknown","uri":null},"spatialDesign":{"label":"unknown spatial design","uri":null},"spatialScale":{"label":"catchment","uri":null},"temporalResolution":{"label":"_unknown","uri":null}}}}
