Dissolved oxygen concentrations in discrete water column samples collected from lakes in the McMurdo Dry Valleys, Antarctica (2010-2018, ongoing)

As part of the McMurdo Dry Valleys Long Term Ecological Research (LTER) project, dissolved oxygen (DO) concentrations have been monitored in several perennially ice-covered lakes in the McMurdo Dry Valleys of Antarctica, including Lakes Fryxell, Hoare, Bonney, and Miers. DO concentrations at varying depths within the water column were measured using mini-Winkler titrations, providing valuable insights into DO dynamics in these extreme polar environments.

作为麦克默多干谷长期生态研究（Long Term Ecological Research，缩写LTER）项目的组成部分，科研团队对南极洲麦克默多干谷内数座常年被冰盖覆盖的湖泊开展溶解氧（dissolved oxygen，缩写DO）浓度监测，监测覆盖弗莱克塞尔湖、霍尔湖、邦尼湖与迈尔斯湖。研究人员采用微型温克勒滴定法（mini-Winkler titrations）测定了水柱内不同深度的溶解氧浓度，该工作为解析这类极端极地环境中的溶解氧动力学特征提供了极具价值的科学见解。
