Glacier 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 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.

作为南极洲麦克默多干谷区长期生态研究（Long Term Ecological Research, LTER）项目的组成部分，本项目开展了系统性采样工作，以监测冰川物质平衡与融水径流过程。本数据集包含泰勒谷6座冰川（加拿大（Canada）、联邦（Commonwealth）、休斯（Hughes）、祖斯（Suess）、霍华德（Howard）、泰勒（Taylor））以及迈尔斯谷1座冰川（亚当斯（Adams））的雪深测量数据，所有冰川均位于南极洲麦克默多干谷区域。绝大多数测量工作始于1993-1994年野外季，亚当斯冰川的测量工作则始于2014-2015年野外季。除休斯冰川与祖斯冰川外，其余冰川的测量工作仍在持续；后两座冰川的监测工作已于2008-2009年野外季结束后终止。对上述测量数据的长期变化进行监测，可形成冰川物质平衡记录，有助于阐明冰川在极地水文循环中的作用。
