Abstract. During the thirty-eight months between December 2018 and January 2022, multiparameter hydrographic measurements were taken at thirty-one sites within Admiralty Bay, King George Island, Antarctica. These records consisted of water column measurements (down to 100 m) of temperature, conductivity, turbidity, and pH as well as the dissolved oxygen, dissolved organic matter, chlorophyll A and phycoerythrin contents. The sites were chosen due to their variable distances from glacial fronts and open ocean waters. Fifteen sites were localized within smaller glacial coves, with waters highly impacted by glacial infusions; seven sites were located in the open waters of the main body of Admiralty Bay; and nine were located in intermediate conditions of the Ezcurra Inlet. The final dataset consists of measurements carried out over 142 separate days, with an average 3.74 measurements per month. However, data were not collected regularly throughout the year and were collected less frequently during winter, though data were gathered for all but two winter months. On average, each site was investigated 98.2 times. Due to calibration issues, absolute values of optically measured properties occasionally show impossible negative values, but the relative distributions of these values remain valid. Variabilities in the measured properties each season and throughout the whole duration of the project reveal regular oscillations as well as possible long-term trends.

注入冰川流入的南极沿海水域的年度水文变化

摘要。在 2018 年 12 月至 2022 年 1 月的三十八个月内，在南极洲乔治王岛金钟湾内的 31 个地点进行了多参数水文测量。这些记录包括温度、电导率、浊度和 pH 值以及溶解氧、溶解有机物、叶绿素 A 和藻红蛋白含量的水柱测量值（低至 100 m）。之所以选择这些地点，是因为它们与冰川前沿和开阔海域的距离不同。15 个地点位于较小的冰川海湾内，水域受到冰川注入的高度影响；七个地点位于金钟湾主体的开阔水域；9 个位于 Ezcurra Inlet 的中间条件。最终的数据集包括在 142 天内进行的测量，平均每月测量 3.74 次。然而，数据并未在全年定期收集，并且在冬季收集的频率较低，尽管数据只收集了两个冬季以外的月份。平均而言，每个站点被调查 98.2 次。由于校准问题，光学测量属性的绝对值偶尔会显示不可能的负值，但这些值的相对分布仍然有效。每个季节和整个项目期间测量属性的变化揭示了规律的波动以及可能的长期趋势。每个站点被调查 98.2 次。由于校准问题，光学测量属性的绝对值偶尔会显示不可能的负值，但这些值的相对分布仍然有效。每个季节和整个项目期间测量属性的变化揭示了规律的波动以及可能的长期趋势。每个站点被调查 98.2 次。由于校准问题，光学测量属性的绝对值偶尔会显示不可能的负值，但这些值的相对分布仍然有效。每个季节和整个项目期间测量属性的变化揭示了规律的波动以及可能的长期趋势。
