Sensing Ice: Explorations of Knowing Nature

“Follow the course of terrestrial ice as it melts and contributes to rising seas in this immersive multimedia exhibit.”
This is a compilation of video that was displayed in three repeating segments as part of an exhibit on the University of Colorado-Boulder Earth Science library from 2022-2023.
Glacial, meltwater, and ocean ice footage in three parts: On the Glacier, Descent, and Ocean. Scenes mainly from Greenland, but also Iceland and one from Nepal.

"Sensing Ice: Explorations of Knowing Nature, an immersive multimedia exhibit about the lifecycle of the world’s ice and snow. The exhibit was designed and curated by Department of Environmental Studies PhD graduate, Chris Dunn. It features large-format photography and video from Dunn’s research and music by Alaskan composer, Matthew Burtner, performed and recorded on-site with glaciers.
The exhibit presents images from different elevations to evoke a global trajectory that is at once measurable and sensual. Dunn’s breath-taking images of the Khumbu Glacier along the flanks of Mount Everest in Nepal represent the world’s highest storehouses of ice and are placed on the first floor of the exhibit. Images of ice formations and transitions descend to images from Greenland’s terrestrial and coastal glaciers as the ice melts into the sea."
Viewers are invited to contemplate the evolving human relationship with ice. The Earth's ice is melting. Sea ice is diminishing while ancient ice caps and glaciers pour themselves into the oceans. To most of us, the earth’s icy landscapes seem remote. Yet, the furthest reaches of the earth are responding directly to us and our daily decisions.
**Most segments have audio, but a few are silent (mainly drone footage).

The first video you encounter focuses on this “region”-the heights of some of the world’s most significant bodies of ice-and depicts various scenes from glaciers in Greenland, Iceland, and one from Nepal. Some display sweeping views, or musk ox pummeled by the wind, but most dwell on early stages of glacier melting:
*A bubble rises from a sediment filled cryconite hole
*Sediment spinning in a tiny rivulet thinner than a pen resembles cellular microbiology
*In larger streams sediment is pushed across ice like blood within a vessel
*After gas bubbles stream out of submerged glacial ice, they break the surface of a cryopond suggesting rain drops on a cloudless sunny day
*Supraglacial streams of increasing size pour through curved channels of ice
The journey as guided by photographs and video proceeds by depicting increasing melt. Meltwater pours into the impenetrable darkness of moulins-smooth, steep, vertical holes in glacier ice-before eventually erupting into tremendous rapids of gray-brown sediment-rich water, until finally joining the sea. The portion of the water that reaches the base of the ice lubricates and accelerates its flow across underlying bedrock.
