Chemical characteristics of supraglacial stream water on Canada Glacier, McMurdo Dry Valleys, Antarctica during the 2015-2016 austral summer

Summary

Abstract: 

This data package contains chemical characteristics of water samples collected along four supraglacial streams on Canada Glacier, located in Taylor Valley, McMurdo Dry Valleys, Antarctica. Samples were collected during the 2015-16 and 2016-17 austral summers in order to characterize the spatial and temporal evolution of glacial meltwater as it travels over and off Canada Glacier. Samples from the 2015-16 austral summer have been fully analyzed and those data are included here. Samples from the 2016-17 austral summer have been stored frozen since collection and have not been analyzed. This package may be amended in the future if analysis of the 2016-17 samples occurs.
