我们通过考虑木卫二的岩石海洋下岩石圈内潮汐应力和放射性热生产产生的热量范围来估计木卫二的全球热液热传输。我们表明，如果控制木卫二潮汐产生热量的因素与木卫一相似，全球热液热输出及其高温分量可能超过地球。然而，在单个系统尺度上，木卫二上的低重力加速度表明单个热液羽流相对较弱。这种微弱的热液羽流不太可能导致熔穿事件，这被假设为形成表面特征，如科纳马拉混沌。需要对集中的热液活动和由此产生的相互作用的羽流进行研究，以解决热液活动对木卫二冰盖可能产生的影响。
We estimate the global hydrothermal heat transport on Europa by considering the range of heat generation resulting from tidal stresses and radiogenic heat production within Europa's rocky sub‐ocean lithosphere. We show that if factors controlling tidally generated heat on Europa are similar to those on Io, global hydrothermal heat output and its high‐temperature component may exceed that on Earth. On the individual system scale, however, the low acceleration of gravity on Europa indicates that individual hydrothermal plumes are relatively weak. Such weak hydrothermal plumes are not likely to result in melt through events, which have been hypothesized to form surface features such as Conamara Chaos. Studies of concentrated hydrothermal activity and the resulting interacting plumes are needed to address the possible impact of hydrothermal activity on Europa's ice sheet.
