McMurdo Dry Valleys Lake Bonney Autonomous Lake Profiler and Samplers (ALPS): Conductivity, Temperature, and Pressure

Knowledge of the McMurdo Dry Valley (MDV) lakes is limited by winter access, a period which is most relevant in understanding the habitability of other icy worlds and critical to understanding the overall function of these lakes. Owing to the lack of winter access, data that normally require human presence are incomplete. Our goal was to conduct the first year-round investigation of the biogeophysics of these unique lakes. An important part of the McMurdo Long Term Ecological Research (LTER) is evaluating carbon and nitrogen budgets in perennial ice-covered lakes. This data set addresses this core area of research and quantifies the vertical profile of conductivity, temperature, and pressure in Lake Bonney.对麦克默多干谷（McMurdo Dry Valley, MDV）湖泊的研究认知受限于冬季无法通行的现状——而冬季正是探究其他冰封天体可居住性的关键时期，同时对理解这些湖泊的整体运作机制至关重要。由于缺乏冬季通行条件，常规需要人工现场获取的相关数据均存在缺失。本研究旨在首次对这些独特湖泊开展全年连续的生物地球物理调查。麦克默多长期生态研究（McMurdo Long Term Ecological Research, LTER）的一项核心工作，是评估常年冰封湖泊的碳氮收支情况。本数据集针对该核心研究方向，量化了邦尼湖（Lake Bonney）内电导率、温度与压力的垂直分布剖面特征。
