MODELING OF ICE SHELLS II
Hammond N. P. * | Near-Surface Melt on Europa: Modeling the Formation and Migration of Brines in a Dynamic Ice Shell [#6024] I examine how the presences of salts affect the dynamics of melt generation and migration in Europa’s ice shell. I find that low-temperature brines can readily be generated in the near-surface by shear heating beneath strike-slip faults. |
Buffo J. J. * Schmidt B. E. Huber C. Walker C. C. | Quantifying Impurity Entrainment at Ice-Liquid Interfaces [#6006] A one-dimensional model of salt entrainment in planetary ices — implications for icy world geodynamics, habitability, and spacecraft data analysis. |

WATER IN ICE: MODELING, FIELD, AND LAB WORK
Takahagi W. * Seo K. Shibuya T. Takano Y. Fujishima K. Saitoh M. Shimamura S. Matsui Y. Tomita M. Takai K. | Mineral Surface-Assisted Abiotic Peptide Synthesis Under Enceladus Alkaline Hydrothermal Condition [#6034] This is the first experimental evidence showing that biologically relevant short polymer can potentially form in Enceladus ocean and has impact on future astrobiology-related space missions. |

WATER IN ICE: MISSION PROPOSALS AND FIELD WORK
Stone W. C. * Siegel V. Richmond K. | Europa Station: Developing a Concept for Higher-Fidelity Analog-Environment Testing of Candidate Ocean World Technologies [#6039] We present a preliminary concept for Europa Station, an Antarctic field camp facility and technology development effort to advance development and testing of fully-integrated robotic systems for subsurface Ocean Worlds missions. |
German C. R. * Boetius A. | Robotics-Based Scientific Investigations at an Ice-Oean Interface: First Results from Nereid Under Ice in the Arctic [#6002] This paper will present new physical and biogeochemical results from the ice-ocean interface in the Arctic collected using the Nereid Under Ice vehicle which can access pristine ocean-ice interfaces that have not been perturbed by ice-breakers. |
Nguyen T. * Nemetallah G. Aslam S. | Microfluidic Imaging for Europa Lander Using Digital Holographic Microscopy Based Convolutional Neural Network [#6009] We developed an optical microscopy for Europa Lancer mission for searching life. Off-axis Digital Holographic Microscope using visible laser and either numerical reconstruction or deep learning-based automatic-defocusing phase retrieval method. |
Lorenz R. D. * | Submarine Hunting and Ocean Worlds: The Importance of Asking the Right Questions [#6010] Operations Research and Bayesian quantification of certainty employed in WWII may help guide Ocean Worlds Exploration by exposing the expectation value of science return from candidate measurements and mission architectures. |
