IceAq Groundwater Hourly Data

<p><strong>Groundwater level, temperature, and sometimes electro-conductivity (EC) in two aquifers</strong></p> <p><strong>- Hourly automatic data, 11 boreholes</strong></p> <p>Spreadsheet describing the groundwater observation network.</p> <p>Map localising the 18 boreholes and 10 springs (2 textfiles, 6Ko): 14 boreholes selected among the abandoned ones, and 4 new ones drilled downstream of Fl&aacute;aj&ouml;kull, on a line toward the coast (FLA1, FLA2, FLA3, FLA4). The network thus constitutes of 13 boreholes in the basalt formation and 5 in the till and glacio-fluvial formation. In addition, we monitored 10 depression springs, 4 from the basalt aquifer and 7 from the till and glacio-fluvial deposits aquifer. All boreholes and springs were localised using a differential GPS in September 2021.</p> <p>Monitoring of 4 boreholes in the till and glacio-fluvial deposits and 7 boreholes in the basalt using automatic pressure and temperature probes, at an hourly time step (6 TD-Diver type DI802, 3 TD Micro-Diver type DI501) and 2 probes measuring in addition electro-conductivity (2 CTD-Diver type DI217). To correct for the atmospheric pressure we used 3 Baro Diver type DI800 and 1 Baro Micro-Diver DI500.</p> <p>One spreadsheet per borehole, giving groundwater level (m asl) and temperature (total 3.5Mo):</p> <p>ASK102 period from 10 Nov 2021 to 13 July 2022 and 17 July to 19 Sep 2022</p> <p>ASK103 period from 16 May to 19 Sep 2022</p> <p>ASK104 period from 17 March 2022 to 21 Sep 2022; in addition EC (microS/cm)</p> <p>ASK105 period from 15 Sep 2021 to 21 Sep 2022</p> <p>FLA1 period from 16 Mar to 21 Sep 2022</p> <p>FLA2 period from 10 Nov 2021 to 21 Sep 2022</p> <p>FLA3 period from 24 Aug 2021 to 21 Sep 2022</p> <p>FLA4 period from 24 Aug 2021 to 12 Jul 2022</p> <p>HA12 period from 17 May to 22 Sep 2022</p> <p>HA13 period from 17 Mar to 22 Sep 2022</p> <p>HA16 period from 17 May to 22 Sep 2022; in addition EC (microS/cm)</p> <p>Origin: MSCA Project Number: 885891 Project Acronym: IceAq</p> <p>Project title: Proglacial and subglacial aquifers: their evolution under climate change and the potential impacts in terms of resources and natural hazards, through the case of eastern Iceland</p> <p>Period of data collection: from May 2021 to September 2022, precise periods specified for each file.</p> <p>Area of data collection: Iceland, south-east of Vatnaj&ouml;kull, Su&eth;ursveit and M&yacute;rar.</p> <p>Accessibility: The data can be read using e.g. the following open source softwares: LibreOffice (https://www.libreoffice.org), QGIS (<a href="https://qgis.org/">https://qgis.org</a>).</p>
