Lake level surveys in the McMurdo Dry Valleys, Antarctica (1968-2026, ongoing)

This data package contains lake level measurements from multiple lakes in the McMurdo Dry Valleys of Antarctica, collected seasonally as part of the McMurdo Dry Valleys Long Term Ecological Research (MCM LTER) program. Measurements were obtained manually using optical leveling techniques relative to established local benchmarks. Locations include Lake Fryxell, Lake Hoare, and the east lobe of Lake Bonney in Taylor Valley; Lake Vanda and Don Juan Pond in Wright Valley; Lake Vida in Victoria Valley; Lake Miers in Miers Valley; and Lake House and Lake Joyce in Pearse Valley. These long-term data provide valuable context for understanding lake level dynamics and hydrologic change in this polar desert ecosystem.

本数据集收录了南极洲麦克默多干谷（McMurdo Dry Valleys）多个湖泊的水位测量数据，此类数据作为麦克默多干谷长期生态研究（MCM LTER）计划的一部分按季节周期采集。所有测量数据均采用光学水准测量技术，参照已确立的本地基准点手动采集获得。本次观测涉及的湖泊包括泰勒谷的弗莱克塞尔湖（Lake Fryxell）、霍尔湖（Lake Hoare）以及邦尼湖（Lake Bonney）东翼；赖特谷的万达湖（Lake Vanda）与唐胡安池（Don Juan Pond）；维多利亚谷的维达湖（Lake Vida）；迈尔斯谷的迈尔斯湖（Lake Miers）；以及皮尔斯谷的豪斯湖（Lake House）与乔伊斯湖（Lake Joyce）。这些长期观测数据可为理解该极地荒漠生态系统的湖泊水位动态与水文变化提供宝贵的研究背景。
