from wetlands located in the South\u2011Western Cape Province of South

70
part of a wetlands research project managed by the Freshwater Research

geographical patterns existed in the major\u2011ion chemistry of

conductivity, salinity, pH, total dissolved solids and nutrients. The

79
later re\u2011analysed for reproducibility as part of the ReScience 
            
80
challenge. The reproduced analysis demonstrated the continued 
            
81
usability of historical environmental datasets and illustrated
