Average glacier stake height and snow depth measurements, McMurdo Dry Valleys, Antarctica (1993-2020, ongoing)

As part of the Long Term Ecological Research (LTER) project in the McMurdo Dry Valleys of Antarctica, a systematic sampling program has been undertaken to monitor glacial mass balance and meltwater flow. This data package includes stake height and snow depth measurements to the surface of six glaciers (Canada, Commonwealth, Hughes, Suess, Howard, and Taylor) in Taylor Valley and one glacier (Adams) in Miers Valley, all of which are located in the McMurdo Dry Valleys of Antarctica. Most measurements began during the 93-94 field season. Adams measurements were established during the 14-15 field season. Measurements are ongoing except at Hughes and Suess Glaciers where monitoring ceased following the 08-09 field season. Monitoring the changes in these measurements over time provides a record of mass balance, and aids in determining the role of glaciers in the polar hydrologic cycle.

作为南极麦克默多干谷长期生态研究（Long Term Ecological Research, LTER）项目的组成部分，研究团队已实施系统性采样计划，用于监测冰川物质平衡与融水径流。本数据集包含泰勒谷（Taylor Valley）内6座冰川的相关测量数据，分别为加拿大冰川（Canada）、英联邦冰川（Commonwealth）、休斯冰川（Hughes）、苏斯冰川（Suess）、霍华德冰川（Howard）与泰勒冰川（Taylor），以及迈尔斯谷（Miers Valley）内的亚当斯冰川（Adams），测量指标涵盖冰川表面的测杆高度与雪深。上述所有冰川均位于南极麦克默多干谷区域。绝大多数测量工作始于1993-1994年度野外考察季，亚当斯冰川的测量工作则启动于2014-2015年度野外考察季。除休斯冰川与苏斯冰川外，其余冰川的测量工作仍在持续；该两座冰川的监测工作已于2008-2009年度野外考察季结束后终止。长期追踪上述测量数据的时序变化，可形成冰川物质平衡的完整记录，并有助于阐明冰川在极地水文循环中所发挥的作用。
