Chemical characteristics of terminal waterfalls along the Canada and Suess Glaciers in the McMurdo Dry Valleys, Antarctica in January of 2018 and 2019

Summary

Abstract: 

This data package contains chemical and other relevant characteristics for several waterfalls situated along the terminus of two glaciers in Taylor Valley, located in the McMurdo Dry Valleys region of Antarctica, during the 2017-18 and 2018-19 austral summers. Specifically, water samples were collected from terminal waterfalls along Canada and Seuss Glaciers as part of a larger study characterizing the geochemical evolution of glacier ice to meltwater. Samples were collected from just above the base of each waterfall and processed using similar protocols developed and used by the McMurdo Dry Valleys Long Term Ecological Research program.
