Ice is one of the strangest, most beguiling
and mesmerising substances in the world. Full of contradictions, it is
transparent yet it can glow with colour, it is powerful enough to shatter rock
but it can melt in the blink of an eye. It takes many shapes, from the fleeting
beauty of a snowflake to the multi-million tonne vastness of a glacier and the
eeriness of the ice fountains of far-flung moons.
Science writer Dr Gabrielle Walker has been
obsessed with ice ever since she first set foot on Arctic sea ice. In this
programme she searches out some of the secrets hidden deep within the ice
crystal to try to discover how something so ephemeral has the power to sculpt
landscapes, to preserve our past and inform our future.
