As new insights have emerged in recent decades about the dynamics of sea ice, researchers have sought to extend these insights to ice covered oceans in the solar system, where nonicy materials preserved in icy lithospheres may hold clues to solid‐state convection and the possible presence of life. The recent study by Buffo et al. (2020), https://doi.org/10.1029/2020je006394, considers the salt content of the ice covering Jupiter's moon Europa in the context of gravity drainage and mushy layer theory, and makes provocative predictions about the amounts of salts retained in the ice. A major question in such studies is how well the preservation and transport of salts in ice translates to the length and time scales of ices in ocean worlds. This work underlines the fundamental importance of including the role of chemistry in the modeling the structures and dynamics of the ice layers in ocean worlds.

冰冷的海洋世界的咸秘密

随着近几十年来关于海冰动力学的新见解不断涌现，研究人员试图将这些见解扩展到太阳系中被冰覆盖的海洋，在那里，冰冻岩石圈中保存的非冰冻物质可能为固态对流以及可能存在的线索提供线索。生活。Buffo等人最近的研究。（2020），https：//doi.org/10.1029/2020je006394，在重力排水和糊状层理论的背景下，考虑了覆盖木星月球欧罗巴的冰中的盐含量，并对含在其中的盐含量进行了激进的预测。冰。这些研究中的一个主要问题是冰中盐的保存和运输如何转化为海洋世界中冰的长度和时间尺度。
