Chemical and sediment characteristics of ice cores collected from the ablation zones of Canada, Commonwealth, Howard, Hughes, and Seuss Glaciers in the McMurdo Dry Valleys, Antarctica from 2015 to 2019

This data package contains chemical and sediment characteristics of ice cores collected from the ablation zones of five glaciers in Taylor Valley, located in the McMurdo Dry Valleys region of Antarctica, during the 2015-16, 2016-17, 2017-18, and 2018-19 austral summers. Specifically, shallow ice cores were collected from the ablation zones of Hughes, Howard, Seuss, Commonwealth, and Canada Glaciers in order to characterize the spatial and temporal evolution of ice chemistry and sediment concentration across Taylor Valley. Cores were collected in triplicate from each sampling location and measured 79 mm in diameter and up to 1 m in depth. Cores were sectioned in 5 cm (0-25 cm depth) and 25 cm increments (25 cm to the maximum depth of the core) prior to analyzing chemical and sediment characteristics.
