Description
Groundwater level, temperature, and sometimes electro-conductivity (EC) in two aquifers
- Hourly automatic data, 11 boreholes
Spreadsheet describing the groundwater observation network.
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 Fláajökull, 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.
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.
One spreadsheet per borehole, giving groundwater level (m asl) and temperature (total 3.5Mo):
