attribute NC_GLOBAL history String Database was standardized by SLGO through an ETL process with the following steps:
- Concatenation of variables 'day' and 'hour' using the 'T' separator to created the 'time' variable;
- Conversion of the 'time' variable from timezone 'America/Toronto' to UTC;
- Conversion of the 'day' variable from '%d-%m-%y' format to '%Y-%m-%d' format;
- Standardisation of header variable names (original name is preserved in the metadata for each variable)

attribute NC_GLOBAL summary String This dataset presents a study of groundwater dynamics along a subarctic coastal environment of the St. Lawrence Gulf. To this purpose, sampling was conducted along a sandy beach located at the base of coastal cliffs in Rivière St. Jean, Quebec, Canada. Water samples were collected to measure concentrations of stable water isotopes (δ2H and δ18O) and short-lived radioisotopic tracers (222Rn, 223Ra, 224Ra). Additional measurements included water temperature and salinity to characterize basic properties of the water masses. Samples were collected from the cliffs, the beach and the seawater. Three sampling campaigns were conducted in 2023 to capture seasonal variations: February (freezing period), April (thawing period) and October (before the new freezing period). A total of 54 samples were collected in these periods to document temporal changes in groundwater flow patterns under variable ice conditions. The results obtained provide significant insights into groundwater recirculation processes and freshwater contribution rates in seasonally frozen coastal environments.
