Scientists at the research station in Antarctica are immured [ɪˈmjʊr] by the frozen wild that surrounds them.

immure
verb [ɪˈmjʊr]

To immure something is to enclose it within or as if within walls. Immure is also sometimes used synonymously with imprison.

Like mural, immure comes from murus, a Latin noun meaning "wall." Immure came to English by way of the Medieval Latin verb immurare, formed from murus and the prefix in- (meaning "in" or "within").
