During the Austral summer of 2022, a study was conducted to investigate the physical properties of six lakes in the Larsemann Hills, East Antarctica. The lake water column's key properties, viz. temperature, salinity, density, fluorescence, and depth, were examined using a CTD profiler to establish a high-resolution description of their variations and identify the factors influencing intra and inter-lake variations. The results indicated that the shallow lakes LH14, LH04, and Discussion were well mixed. Lakes LH04 and LH14 on Stornes were affected by salinity, likely sea spray. In contrast, the deeper lakes, namely Nella, Cameron and Progress, were primarily driven by temperature and density dynamics. The hydrological characteristics of Cameron and Progress were notably impacted by their proximity to the ice sheet, while Nella was influenced by the presence of a partial lake ice cover. The lake depth, geographical location and presence of ice cover in the catchment significantly influenced temperature and salinity variations within the lakes. Deep lakes may be more sensitive to changes in temperature and density as compared to shallow lakes and could potentially affect other physical lake parameters. This baseline information is a valuable reference for future investigations on these lakes and similar environments.

2022 年夏季，开展了一项研究，调查东南极洲拉斯曼山六个湖泊的物理特性。湖泊水柱的关键特性，即。使用 CTD 剖面仪检查温度、盐度、密度、荧光和深度，以对其变化进行高分辨率描述，并确定影响湖内和湖间变化的因素。结果表明，浅水湖泊LH14、LH04和Discussion混合良好。斯托恩斯 (Stornes) 上的 LH04 和 LH14 湖受到盐度（可能是海浪）的影响。相比之下，较深的湖泊，即内拉湖、卡梅伦湖和进步湖，主要是由温度和密度动态驱动的。卡梅伦湖和进步湖的水文特征明显受到靠近冰盖的影响，而内拉湖则受到部分湖冰覆盖的影响。湖泊深度、地理位置和流域冰盖的存在显着影响湖泊内的温度和盐度变化。与浅湖相比，深湖可能对温度和密度的变化更敏感，并且可能会影响其他物理湖泊参数。该基线信息对于未来对这些湖泊和类似环境的调查具有重要参考意义。
