地热热流（GHF）是一种难以捉摸的物理特性，但它可以揭示过去和现在的板块构造过程。在南极洲，GHF 在预测冰盖对气候变化的反应方面具有进一步的影响。在这篇综述中，我们讨论了基于地球物理方法的南极 GHF 模型的变化，并深入了解了构造学和 GHF 模型在冰盖建模中的使用。推断的西南极洲大陆尺度的 GHF（高达 119 mW m−2，第 95 个百分位）指出了许多影响因素，包括非稳态新构造过程。综合影响导致思韦茨冰川附近的数值特别高，该位置对于准确预测南极冰块加速流失至关重要。整个东南极洲的推断变化更为微妙（高达 66 mW m−2，第 95 个百分位数），其中某些位置的值略有升高，这与岩石圈变薄和产热元素集中的构造单元的影响相对应。由发热元件和热流水平分量引起的细尺度异常对于区域建模非常重要。因此，由中心值和在不确定性范围内捕获的这些精细尺度异常组成的 GHF 地图可以改进基于集合的冰盖模型对南极冰损失的预测。✉ 电子邮件：anya。阅读@utas。教育。 au https://doi。 org/10.1038/s43017-022-00348-y
Geothermal heat flow (GHF) is an elusive physical property, yet it can reveal past and present plate tectonic processes. In Antarctica, GHF has further consequences in predicting the response of ice sheets to climate change. In this Review, we discuss variations in Antarctic GHF models based on geophysical methods and draw insights into tectonics and GHF model usage for ice sheet modelling. The inferred GHF at continental scale for West Antarctica (up to 119 mW m− 2, 95th percentile) points to numerous contributing influences, including non-steady state neotectonic processes. Combined influences cause especially high values in the vicinity of the Thwaites Glacier, a location critical for the accurate prediction of accelerated loss of Antarctic ice mass. The inferred variations across East Antarctica are more subtle (up to 66 mW m− 2, 95th percentile), where slightly elevated values in some locations correspond to the influence of thinned lithosphere and tectonic units with concentrations of heat-producing elements. Fine-scale anomalies owing to heat-producing elements and horizontal components of heat flow are important for regional modelling. GHF maps comprising central values with these fine-scale anomalies captured within uncertainty bounds can thus enable improved ensemble-based ice sheet model predictions of Antarctic ice loss.✉ e-mail: anya. reading@ utas. edu. au https://doi. org/10.1038/s43017-022-00348-y
