Trapped!
Ice bubbles
The cold moved in fast and hard, and in short order, it was back to feeding the implacable appetites of two woodstoves to keep the house warm enough so its inhabitants could avoid freezing solid. At the millpond, that option was unavailable and fresh ice was soon the order of the day. The phase change was fast enough to trap bubbles of air and other gases in the crystalline matrix. In the Arctic and Antarctic, scientists can actually sample the contents of the bubbles found in ice cores and obtain clues to ancient climates. Here, my interest in the bubbles is purely aesthetic—they make fine photographic subjects.
