Intro
Ocean World Microhabitats 101
The search for life in the Ocean Worlds What is the spatial distribution of life in the Deep Ice habitats of Ocean Worlds? How do we look for it?
Deep Ice in the Solar System Ocean Worlds have very deep ice; the largest have ice convection
Deep Ice will be the first habitable environment encountered in Ocean World exploration
Analog Ocean World environments with microhabitats
Comparison of cell sizes Deep Ice microbes are ultrasmall
Many many many microhabitats in ice
Microhabitat targeting workflow Detect acquire analyze
First step: Microhabitat Detection Fluorescence is good technique for spot detection
Excision diameter How do we drill out a target sample?
Excision diameter not same as feature diameter Excision diameter is diameter needed to melt drill and acquire target
