Project highlightsa. to map the major, minor, isotopic and ionic interstellar ice species across a range of molecular clouds, probing dense extinct regions. YOs and their docs as well as cloud edges, to identify their distribution as a function of column density.b. to compare ice column densities to gas-phase emission, to text the linkages between gas and solid-state, molecules according to our current astrochemical understanding, and establish ice abundances.c. to compare ice abundances with dust emission maps, to test the formation, evolution destruction of ices as a function of temperature, dust, density and local astrophusical conditions.
