在南极洲的一系列地点，利用机械叉和连续温度数据记录，在环极活动层监测-南方（CALM-S）计划下，对活动层融化深度和活动层厚度（ALT）进行了监测。本研究的目的是总结2006年至2015年南极不同地区站点的关键数据，以审查南极活动层的状态和CALM-S计划的有效性。研究中使用了南极16个地点的数据，包括8个CALM-S和另外8个钻孔。探测融化深度，同时提供当地的空间变异性的信息，往往低估了南极土壤的最大ALT相比，使用连续的温度监测确定。这些差异可能是由于石头限制了探测器的穿透，探测的时间与最大解冻的时间不一致，而最大解冻的时间在季节之间变化。在许多区域，关于活跃层深度的资料仍然很少，监测工作需要扩大和继续，以便更好地了解南极土壤热特性的空间和时间变化。
ABSTRACT Monitoring of active layer thawing depth and active layer thickness (ALT), using mechanical pronging and continuous temperature data logging, has been undertaken under the Circumpolar Active Layer Monitoring – South (CALM-S) program at a range of sites across Antarctica. The objective of this study was to summarize key data from sites in different Antarctic regions from 2006 to 2015 to review the state of the active layer in Antarctica and the effectiveness of the CALM-S program. The data from 16 sites involving 8 CALM-S and another 8 boreholes across the Antarctic have been used in the study. Probing for thaw depth, while giving information on local spatial variability, often underestimates the maximum ALT of Antarctic soils compared to that determined using continuous temperature monitoring. The differences are likely to be caused by stones limiting probe penetration and the timing of probing not coinciding with the timing of maximum thaw, which varies between seasons. The information on the active layer depth is still sparse in many regions and the monitoring needs to be extended and continued to provide a better understanding of both spatial and temporal variability in Antarctic soil thermal properties.
